- In this video, I go over the process of completely restoring an A12Z-based Apple Silicon Developer Transition Kit "DTK" Mac Mini that I got from China sold essentially as scrap. After many months of work, research, and testing, I was FINALLY able to fully restore one of these salvage DTK logic boards, and get it back up and running booting macOS! The culmination of all that work is shown here, as well as the process of making it into a complete DTK machine using a 2018 Mac Mini chassis and parts.

Cool. My company was able to get a few of these DTK's and I had a bit to do with setting it up for the rest of our staff to use it. I had to lock it up in a room that only a few people (including me) could unlock and the rest of staff used it over remote access. When the time was up, Apple's lawyers were pretty adamant they wanted it back pronto, so I had to box it up and send it back via their special courier. Thanks for showing me what the inside looked like!
Why is that? Can you do anything with these?
@@Rollmops94 The OP would have been using the DTK for it's intended purpose not for a laugh and a giggle. The video explains what the usecase of these DTK's was.
@@adem1781 Thanks for nothing.
@@Rollmops94 the reason these were locked up is because they are the first ARM boards that could run MACOS, and apple is a jealous cunt and thinks they invented every technology that they copy from others
I had one also but as an independent developer and the process was much less threatening sounding. I originally wasn't even going to bother because it sounded like they had very few and were going to be pretty restrictive with who could get them, but a few weeks after they had started sending the kits out they sent a reminder email to developers that they were available and at that point I decided since they clearly weren't all gone I might as well try. I've never even published anything directly to the Mac App Store, I just gave them links to multiple apps I developed and they approved the application and sent the DTK.
There was no special courier and the return was just a normal prepaid FedEx shipping label.
It's pretty cool that someone was actually able to activate one of these several years later, I'm surprised they didn't disable that on the server side.
This reminds me of a big box of windows 98se cds I recovered from a business that shut down and they tossed them in a dumpster. They had never been installed, or even opened, but they were supposed to be destroyed and written off. The way they choose to destroy them was to drill a hole through the installation cd. Unfortunately they only drilled through the box and went right through the center of the disc and through the hole that was already there. Not a single one was damaged and I managed to save and sell 120 discs for $40 each. That was a good day.
Wow that was stupid of them
@@YimYum911 probably the easiest way to drill into those packages - and since the checkmark "drilled" was reached, the intern doing it didn't care for doing more damage
Sounds like you beat them from their planned dumpster dive.
I don't understand why businesses do things like that. I found my own main PC in perfect condition in a dumpster similarly to this.
@@JoBot__ They do it because of depreciation and taxes. They are allowed do deprecate a PC in as little as two years if they want. So, in two years you allowed to claim back the full value of the PC (pay less tax). You can keep that PC if you want or dump it and get a new one and again claim back on your taxes. Is that the question?
Many companies “destroy” prototype equipment when it is no longer needed due to IRC 174 (tax code). Basically the prototype is rendered reasonably worthless to insure it is no longer used by the company or anyone else, otherwise they do not get to deduct the cost of the prototype. The IRS became very concerned in the 1990s that companies were writing off the prototypes but still using them in business (if it’s still being used you can’t write it off). The developers basically leased it, and at the end of the lease they would send it back and get a credit for what is essentially a production level replacement (a bare bones Mac mini for developers was about the same price). They got the credit no doubt because maybe they might rather have something better than a base model Mac mini, like maybe more RAM, or more storage, or maybe a laptop instead. Cutting the PCB is just due diligence, certainly it “could” be fixed, but probably the amount of work would not be worth it. Though a determined you tuber with a soldering iron might fix it not for its intrinsic value, but for the views as well.
Company: makes functional prototype
IRS: destroy that for tax money
Company: how much?
It's stuff like this which makes our society so wasteful and perversely incentivized
@@maverick9708 Tax office and legislature want taxes be paid, not avoided
Yeah, the point is that they genuinely won't derive any more value from them, but the IRS doesn't know that if they export them. Breaking them first is easier/cheaper than maintaining records of what happened to them
I also kinda object to another common feeling people express. These aren’t “perfectly good machines”. They are a low volume orphan with limited potential. The processor wasn’t an M1, it didn’t support all the important MSRs that the M1 had (some for instance might make Rosetta work better). It didn’t have the same number of cores in the same configurations, the peripheral interfaces were not the same as the M1. Apple wouldn’t want to support this configuration in a shipping OS. “But Linux” you say… sure, but what district would want to carry around support for such a limited machine? It isn’t a waste, it is just how development works, there are steps and often times the intermediate steps are simply limited usefulness. Historically significant, sure, and I am confident that apple saved a few examples for its archives. I am equally sure that somewhere out there some developers didn’t turn one back in (probably more than one maybe). Either that developer just forgot, or intended to give it to a museum so others can enjoy it, or simply keep it secret for long enough to sell it to a collector for a profit later. (Which sounds a little shady I guess)
@@jonqu7041 This is a fair point "Apple wouldn’t want to support this configuration in a shipping OS", but I still think it's very wasteful that they deliberately destroy them! If people want to use them, they should be able to do, apple can just be very explicit that they are unsupported.
The fact that this is considered normal is a pretty bad sign of how our society works.
This is absolutely astonishing. Your fix for the cut to the PCB is nothing short of miraculous; never would I have thought a multi layer PCB like that could ever be operable again after damage like that. Amazing repair of a piece of Apple history.
Depends entirely on where the damage is on the board.
If it's through power rails, but doesn't affect any rails which are vital for basic functionality like in this case, you can just clear the damaged area and it'll work
If the board's snapped in half and is multi-layer you're SOL since the traces under the surface layers can't be accessed to be rejoined without destroying the other traces above them. Same if the damage is more centralized, the board was drilled or the damage has occurred in an area where a lot of critical power and data traces reside.
It is possible to repair PCBs, including traces deep within a multilayer board. It just becomes more and more expensive to do, so it’s rarely worth the effort.
Take a look at Pace’s “Adventures in Rework” video series. They demonstrate excavating traces, fixing them, and then repairing all the layers above them to restore the whole PCB.
Insane amount of research to get this to work. There were so many points where I thought "how could he possibly know that".
This right here
plot twist: bro's hacking irl 💀
Dude, mask off the drilled hole with UV-resin. It will isolate the layers and improve board integrity
Already did that actually.
That was kinda what I was thinking. This answers my question heh
Ok bro
I once punctured my HDD pcb with a very small Phillips head screwdriver. HDD wouldn't respond whatsoever. I took out the pcb and after some careful observation, noticed there weren't any traces at or near the puncture, so I took a flathead and slowly ground away. Once there was a sufficiently large enough hole that I could clearly see through, I cleaned it off to make sure there wasn't any copper dust and finally taped on both sides to prevent anything going in and causing a short. Plugged it into my PC and it started working again. It's still in my PC right now, haven't had any issues whatsoever.
I hope for your own sake you have backups 😅
@@spicybaguette7706 screwdriver is his backup
I'd replace that hdd immediately
That's one way to get rid of a virus! 😅
So there were no traces near the hole, but it wouldn't respond, and after you made the hole bigger, it worked perfectly? That makes absolutely no sense.
You truly have a gift, Collin.
I'm just in awe, that this guy would even try to repair that cut.
@@cathrynm it’s nuts. It takes courage I certainly don’t have! But I suppose, if it’s already broken, nothing to lose if you have a level of patience I also don’t have lollll
Maybe he could put Mac-OS onto M1, 2, ...& A11, 12, ... iPad PROs ? Truly gods work if this would happen, .. & build hacking community about such a process!!
@@johndfella1That would be a sight to behold. It would also make the iPads worth their crazy high prices!
Yeah, the soldering work alone, on those tiny components. Like he could do it blind. That would have taken me a week of trial and error 😅
not going to lie this was one of the most in depth repair and programming I've seen in years. absolutely wonderful video. keep up the good work brother.
I remember a guy at work had blown a fortune on a dual pentium server board to get a bit of a gaming advantage while everyone else had the fastest CPUs but only one of them.
He had his PC setup for ATX and when he first installed the MB there was a standoff sitting right where a heat spreader is mounted on the server board and this high spot caused the board to crack when he screwed it down. After this was discovered I helped him move the standoffs to the right spots for his server board and we got it running, but someone walking past his computer was enough vibrations to cause random errors. It was so painful watching him suffer with it.
I love watching these videos. It amazes me to the extent Apple goes to make the devices unrepairable and unserviceable, but smart people have developed tools and the knowledge to make it work.
Truly awesome.
This one is a two part screwing,
The IRS for saying you can write its expenses off if you destroy it and apple for complying
they have to destroy them by law.
In the name of sustainability this shit needs to stop.
@@maverick9708 Imagine if I could write off my car as expense if I said it was a prototype and just destroyed it.
I agree with you, but that's not what happened here. They wanted to destroy these machines specifically because they were never supposed to be given to anybody but developers on a temporary basis. The fact they were dumb enough to trust some random Chinese recycling company to not resell them is funny though.
It’s a shame they tried to destroy them all, but now you get to have a super rare piece of kit. Very awesome work!
I know your content is mainly hands on work on systems, but I would love to see a deep dive into this machine. As it was under so many NDAs and whatnot when it came out, there wasn’t much info. It’d be fascinating to see benchmarks, any quirks in the OS, that kind of thing.

incredible work by the way!

You, sir, are continually redefining my perception of what's possible. Bravo!
I don't get all the people suggesting that Apple would have a legal leg to stand on to give Colin grief about this.
I *am* surprised they didn't blacklist the serials from activation after the program was over.
_They might, now._
They will, next week now that this video was released, and someone somewhere will get in trouble for not sufficiently disabling them - big companies like to pin their problems on some unfortunate schmuck somewhere, rather than managers take responsibility
I'm surprised as well, xbox and sony did this with xbox 360 and ps3 dev kits back in the mid 2000's. If they logged online they were effectively bricked.
@@jforce321same with the Xbox one x dev kits I believe
@@lordgamer0912 yeah they've all done it since then just mentioning how far back they started
Not even the weirdest DTK apple made, The one they made for the move to intel was a Pentium 4 in a power mac G5 chassis.
thats not weird, just lazy.
@@domi8585 more like logical, as Pentium 4s were known for their heat, as were the latest PowerPC variants.

@@domi8585 Not lazy more like cheap, it wasn't a commercial product for the masses so why invest in a ton of R&D for it.
Amazing work! Thank you so much for taking the time to film your process and documenting it so thoroughly.
Hats off to all the tool makers who build out the hardware and software to enable craftspeople like this to make a functional tool good. 👊👏🙏
It's immensely satisfying to see such things resurrected. I'm delighted that you were able to make it happen and to have one in spite of Apple's efforts to the contrary! 😊
Reviving stuff like this makes me so happy, and your skills amaze me!
It's genuinely incredible to watch you work on these projects, amazing that you were able to get that thing working!
Omg I used one of these with the original macOS 11 beta build--it was terrible if not unusable: slow, freeze prone.. At least those issues were fixed, and the final product worked well!
Lol, perhaps it's a "feature".. i.e. if your software works ok on the DTK, it'll _fly_ on the actual device..🤭
@@mugwump-bk7os At work, we nicknamed Big Sur as "Bug Sir". Ironically, Apple accidentally put it as Bug Sir on a KB article until I used my connections to alert them...LOL. Big Sur on ARM was extremely buggy for the first few months.
@@mugwump-bk7os At work, I never wanted the fastest PC to develop on. All my stuff was for internal use. If it ran good on my box, it would run good on anyone else's. The last thing you want is the fastest PC in the company where everyone else is 2 or 3 steps behind. You WILL HEAR about it.
This video is so crazy. It's just amazing how far you can go with the hardware, such as reprogramming the NAND gates. Wow!
Dosdude, first off I want to congratulate you on your dedication and hard work to get this project running. You’re also super-smart, though I’m sure you’ve heard that plenty of times before. Literally during the entire video, I was thinking, “How does this guy know this much?!”
Now secondly, I want to challenge you. The DTK is a very cool Mac, one that I would love to see continue to live on. It can sort of do it on macOS Big Sur, but with even Sonoma about to be superseded come WWDC, I wanted to ask if you’d be up to the task of developing a patcher specifically for the DTK that would allow it to be updated as a normal Mac. If so, that would be absolutely amazing.
Thank you for all you do!
Collin as a user of the OpenCore Legacy Patcher I appreciate your dedication!!
Goes to show…..This is an interesting video..and also goes to show that an iPad would totally run MacOS “if apple wanted it to” - The Apple Dev kit was a ipad A12z chip on a mac mini form factor mobo.. so its CPU/GPU totally can
What are the 3 coin cell holders for? One wouldn't be out of place but 3 just seems odd?
It was for the sheer amount of power the silicon pulled on these DTK boards. Even with those batteries, it could still only last for essentially the duration these were available for.
This was essentially an iPad chip working in a desktop form factor, and there had to be some way to persist the RTC upon power failures even if it really did guzzle through those coin cell batteries.
@@FairPlay137 ah so the coin cells are basically replacing what would have been the original iPad battery that would have been used for keeping time.
@@FairPlay137 Oh okay that makes sense thank you!
Thank you for asking this question.. I had to shake my head at DOSDUDE for not even mentioning what the hell they were.
Shame on him... and he's supposed to really teach us about these boards -_-
Wow @@FairPlay137
It's remarkable such a crude and ape style repair technique can fix anything.
Huge kudos to you. Love your methodical approach in walking through this and getting the DTK up and running. Really amazing work and patience!
A really fascinating and informative watch. Your natural enthusiasm is life-affirming and infectious so thank you for the lift :)
Awesome video. We need more obscure hardware in our lives :)
i happy to see this job ended with success because you worked so much on it
Bro, you never cease to amaze me. I wish I had the kind of skill that you had when it comes to this stuff because you have defied apples laws in so many different ways. It just goes to show that people like you are the people who actually own the future in tech, not these large corporations
Made my ear lobes tingle with delight and joy! Bravo on an ineluctably magnificent piece of computer restoration and thank you for sharing! A think of beauty is a joy forever.
I have owned, and unfortunately sold, a few Apple prototypes including a Prototype "Pismo" and a red G4 QS Logic board; the Apple hardware ecosystem is so damn cool to marvel at... so much fanatical culture and things to geek over, I am in awe of your DTK and I am guessing it will be one of your prize possessions. This is literally like finding an original hand painted copy of the Mona Lisa that was painted over and had a few holes in it, and then restoring it to 100% and hanging it on the wall in your bedroom. Recording the process for all mankind, yet enjoying it quietly for yourself; as always, I applaud both your skills and tenacity my friend.
As a Pismo owner and fan, I'm very curious about what the Prototype was like.
Or it's like taking a shit in a bucket, sniffing it to reminisce the essence of a days past... This is cool, you huff shit bucko

Really fascinating how involved a project like this is.
I don't know why I've watched this. BUT now I know about the DTK. Thanks a lot 😊
I didn't understand much of the whole procedure, but as long as it means giving Apple the middlefinger, I'm all for it. I hope it helps to understand better their proprietary crap in order to crack it open. Kudos for what you're doing, keep it up.
Definitely a cool Mac, a lot of work but it’s awesome to see one in action! Reminds me of the Intel transition “PowerMac” with a Pentium 4 inside. Great video!

I dunno why I watched the whole video but I did. Respect for your retention of the know how to go about this type of eh stuff😊. I used to break apart components from tech stuff for gold and scrap. Thinking of making a short spoof video of what my attempt at a go for this would look like. Godspeed young man!
Another fantastic video from great man! Congrats!
You have such amazing patience and character. Really enjoyable watch. Thank you.
Fantastic to see you resurrecting history Collin
I did enjoy the video, I love to see people restore stuff that should never be trashed in the first place.
Really great video. I'm not an Apple guy and I thoroughly enjoyed watching this. Good work.
I feel like this would be one of those awesome items you write in your will to donate to a computer history museum
While not really practical compared to an M1 Mac, I feel like this hardware is more interesting than the intel transition dev kit
Nice work Colin! Btw why don’t you get the dremel 225 flex shaft attachment, that makes this sort of thing much easier.
This is sheer madness and I'm here for it.
i love that you went to such lengths to save something from the landfill! maximum respect :)

Legend
As always impressive video!
I believe you had put insane amount of work to overcome the hurdles before having it to work and getting the processes recorded on camera.
Maybe you're the only one on this earth have it working now. Amazing work as always Collin!
Couple of questions though:
1. Do you think 2x NANDs configuration will work knowing that you have the Data from the FDR server?
2. Do you think one day you'll able to bypass it to run OS later than Big Sur? Because we all know the M1s also might not get the latest MacOS update soon/in future
1. FDR server is only for syscfg data (not the same as NAND firmware). Though, I still have gotten dual-NAND working no issue on these, you can use NANDs from A12Z iPad Pro. You can also install blank M1 NANDs onto A12Z iPad Pro board, restore on there, then they also work on DTK (after programming correct serial number and such of course)
2. I absolutely intend to attempt to get later macOS versions running. If successful, I will be prepared for the future when they stop supporting M1. Hopefully that won't be any time soon haha.

Would it be reasonably feasible to modify an iPad Pro to run full macOS? Or an iPhone for that matter?
What are those 3 button cell holders for?
The three button cells are for the CMOS/PRAM memory because apple didn’t spend the time to optimize the power draw. Thus the three cells to keep it alive long enough for the time devs were using them
Nice job! Loving the XP!
This is the definition of “if there is a will there is a way” Well done 👍🏻.

After watching this , i have to wonder if you could install Mac OS on a iPad using DFU mode & if you could would the touch screen still work
I would love this
Maybe on very early stage prototype devices with factory protection fusing, definitely not on a production device.
@@bemorewantless so would a lot of Mac users including myself if it was possible I wouldn’t hesitate in trading my two MacBook Air laptops for an iPad Pro 13 inch fully loaded

I hope you keep having success like this, and share the details. Altho you skip over the details on how you failed here and there, it would maybe be interesting as-well, to learn from other peoples mistakes.
Thanks and also tons of other awesome content, apparently i seen one other vid already. subbed :D
I've never seen this channel before, and I'm only minimally interested in this subject, but anybody who sees a delicate Crapple PCB from a modern device and gets out the dremel right off the bat deserves a watch and a like.

You have the hands of a surgeon my friend and I have worked with a lot of surgeons. I started doing a little SMD work following you guys but nothing on this level. I am curious why Apple would destroy them. They are only worth scrap... or to collectors who would pay more than scrap price as is no warranty same as the scrap dealers. I am sure there is some business/legal reason but makes no sense to me.
Tax.
halfway through and loving the vid, you are a true wizard!
This is a great informational video, thanks for sharing!
Using an iPad chip in a Macintosh and having it run full macOS in its unrestricted glory means that iPadOS needs not be so locked down at all, and that the SoC supports free form window management….
I´m always so confused by comments like this. If you want a laptop get a laptop. Nobody who uses an iPad actually wants a window manager.
@@JonGretarB I use an iPad Pro and would love a much better window manager… I’m so sick of dismissive comments like yours i.e., “because I don’t do something means everyone thinks just like me!” Apple put the name “Pro” in iPad, they also gave it the Mac chip when they didn’t have to… they gave us proper mouse support, which once upon a time did not exist, in the m4 generation they moved the camera to the top of the screen like on a MacBook, they also gave us an excellent keyboard with function keys like a MacBook… it’s clear from the hardware perspective, iPad Pro pro is much more Mac like than ever before. Apple also gave us thunderbolt (with pcie tunneling), and the ability to connect to a monitor (with DisplayPort tunneling). These are Mac like hardware features.
But the software is too limiting. Apple should bring macOS lite (with the traffic lights 🚥) and free form window management, possibly the ability to run Mac apps, the ability to use more than one audio source simultaneously. The files app should have the ability to unmount media and format media with no partitions (give us APFS, HFS, exFAT … just like on Mac). The hardware is already more than capable… the software needs its training wheels taken off and let power users tap in to the hardware. And just like stage manager, if you want to turn off the free form window manager and go back to ‘regular iPad OS’ then give us that option as well. I think Apple needs to stop presuming that only it knows best what the user shall be able to do with the hardware, and instead empower users to be able to use the hardware in a more open manner, similar to how it is on the Macintosh. The Macintosh is a great paradigm for what an Apple operating system can be.
i bought one on ebay to reference for repairing damage to a different one (components torn off up by the ports and a hole drilled in it) and it has the same serial number and identical damage
neat
You probably bought this one, which I sold on eBay after filming this video.
Subbed. I know how hard it is to work with SMD on that scale, and you made it look effortless. Good work, seriously.
Such a great job. Thanks for the video.
What, so you didn't do anything for traces and it works just fine? mind blown
No crucial traces in this area, luckily.
luke mini wishes he could do this
Me too.😀
such skill and such knowledge demonstrated here. so much respect!
You guys/gals that can solder the complex surface mount parts really impress me. The fix for the cut board was slick. I grew up in family electronics business, like from back when TV''s were all tubes and hand wired chassis lol Was really fun being involved in electronics especially the evolution of computers and programming over the decades. That said this kind of repair is way beyond my old shaky hands and not so good vision lol Nicely done !
It's not that hard unless you really want lead free solder. After a few hundred components it's still fiddly but you'll get there.
So strange seeing it with 3 battery slots 😆 I wonder why
Basically the circuitry that is responsible for the real time clock? Or nvram? Not really sure is not optimized at all and uses "a lot" of power when the system is off. So the quick fix was to tack on multiple batteries because it's a prototype after all and was designed to be returned after a few months. I read somewhere that even with the three batteries installed it drains them in a few months lol.
The SoC was designed for use in an iPad, which has a gigantic battery at its disposal to run the SMC/RTC coprocessor off of when the device is off. In that instance, the amount of power it draws is not an issue. The DTK doesn't have that, of course, so instead they added multiple coin cell batteries... Which even then, still die after 6 months.
@@dosdude1Ah that makes a lot of sense. it was such a joy seeing you bring this back to life. Seeing that restoring software bar move along after all the trouble you went through... I am so glad this unique piece of hardware made it into the right hands. Thank you for persisting and saving it. And thanks for the reply too. That's hilarious that even with the added capacity of 3 batteries that it still only lasts 6 months 😆
