1. A system with High Sierra installed has pulled down firmware for the machine when the installer runs, and it's supposed to lock out previous OS versions running. So the Sierra install not booting is about what I expected. 2. You're getting permissions errors under single user mode as root, because the system libraries are under Apple's SIP protection. So it won't let you do much.
5:15 Isn't the recovery partition sometimes hidden? Wouldn't you have had to press Cmd + R with the internal boot drive selected? Also, when you did press Cmd + R a few seconds later, the Apple logo appearing means that either it didn't detect the key press or local recovery is loading. If internet recovery had been loading, a spinning globe would have appeared. Am I right, Ken?

Don't recommend the owner to buy another 2011 15" MBP, these GPU"s are extremely prone to failing, so probably another one would fail pretty soon as well.
High Sierra runs pretty well on my 2011 Mac Mini, though it is a pretty damn virgin install (only added Chrome, Diablo 3, Hearthstone, the Battle.net launcher and the orginal Call of Duty). It is slow to boot though. Guessing the ol' 5400 RPM HD doesn't cut the mustard in this SSD world
I can confirm that is a 2011 / older model. Looking closer at the laptop in full screen, and it looks like it has a dashboard key instead of a launchpad key. The more you know.
It looks like there is a problem with the GPU firmware that is preventing it from changing into 3D mode to display OS animations and effects, that's why removing the drivers worked because without the drivers it won't try to change into 3d mode. You might be able to repair this by flashing the GPU rom.
My 2018 MacBook Pro shipped with High Sierra despite Mojave being released when I got it (I got it new btw) and I thought this computer was broken sometimes because of how glitchy it was on high sierra. But I upgraded my MacBook to Mojave and this has been the best computer I have ever used in my life. I have no idea what was wrong with High Sierra but I really did not like it.
Good video, perhaps I missed it but I would've tried to boot in verbose mode so you could try to capture what was happening when it went to the white screen without the loading bar and hung there. I recently had this issue with a much newer iMac and it turned out it was trying to find wifi constantly (obviously not the issue with this laptop) but had I not used verbose boot I would've never known where to look first. Also perhaps it's an issue with that specific SKU + High Sierra combo? Try rolling back the OS or do as others have suggested and try booting an alternative operating system to see if they reciprocate the gpu hardware issue. Anyways, good luck! Your videos always make me laugh :)
i think the whole logic board needs to be replaced. my dad has a 2011 15” MBP and it also had an endless boot loop problem. he did some research and eventually replaced the logic board to see if this would fix the problem, and it did! the computer runs perfectly and there hasn’t been and problems with it since.
in Most cases its yust the C9560 300µF 2.5V Tantalium Capacitor which supplies the power to the GPU Replace it with a New Equal or even better 330µF 3.0V Aluminium Organic Polymer Capacitor
They only started the repair program for the 2011 MBP solder flaws in 2015, you were only applicable three years from the date of purchase, and ended in 2017. Miss any of those windows and you were boned. Nice, huh. Richest company out there isn't beyond bill dodges, and maybe that just makes sense.
've got a 2013 MacPro. Apple managed to build yet another GPU issue into the system with the D300, D500 and D700 FirePro cards crashing randomly. Apple so far has not provided a true fix so I will probably have to get an eGPU to get around that problem. Apple should know better. Very frustrating
To internet recovery it needs to be connected to the internet and select it from boot picker (if not connected to internet you can connect from boot picker and if its not connected to internet, internet recovery won't show up in boot picker)
Having experienced GPU failure on a Windows machine several times, yeah, that screams GPU failure. The behavior in Windows is that everything works just fine until the GPU drivers load properly, then all manner of chaos happens, the GPU driver crashes, and the computer typically BSOD's. Not really trying to Apple-Bash here, but I just find it amusingly typical that Apple obscures the reason the system crashes, while Microsoft gives you a BSOD with an error code to look up. (A hint for Windows users: If your rig's crashing with a 0x116, it's either the GPU or the GPU drivers.) First thought I had, though, was bad RAM. I've had laptops not boot because of RAM before, and they'll get surprisingly far (had a couple actually get to Windows before crashing) on occasion. Any time I see a laptop, I suspect memory, because laptops move a lot, and all it takes is a memory module getting wiggled out of the socket just ever so slightly, and you're in for a world of trouble.
I don't use an apple device but on older versions of mac os x the os would die and start spewing os logs onto the screen, but they dont show the reasons anymore :(
Windows error codes arent as accurate anymore on BSOD cause for some reason they stopped doing hexadecimal error codes and instead using strings which mean multiple things
@@_danu Oh, that's just stupid. At least the hexadecimal codes could be Googled and a solution could be found. Microsoft needs to understand that they are not Apple, and Windows will never be OS X, so they should quit trying to appeal to the Apple fans because all that does is make it _easier_ for their normal customers to switch to the Apple products.
I have the same model of MacBook Pro , whenever you connect it to power it turns on the charger light in green but very dimly, when it finally decides to turn on it’s stuck on a boot loop, if it doesn’t you will have to enter in safe boot, if you are lucky it will turn on normally but when ever you disconnect it from the power and try to open anything it will shutdown and you will have to start all over although the battery is new it has the same problem and I don’t nor what to do.
I think recent versions of the macOS (later Sierra updates and High Sierra) hide the recovery partition from boot picker and maybe Disk Utility as well. It's on there. Thus the different behavior (I hate that Apple hides things like that). 11:20 I don't trust High Sierra. I just don't have the time to deal with a slowing then corrupting APFS boot drive and no Mac to read it in TDM again. :/ My e2011 MBP i5 13" will never have High Sierra on it. Ever. It's probably my last Apple computer as well. I'm done with Apple as it is in its current form as a company.
Ryan Martinez I just hate them for two reasons: 1. high sierra was fully downloaded, but decided to download all 6 GB again?! 2. they force my poor SSD to get f***ed by APFS with no option to disable it! Background: I could measure lower boot times and better responsiveness with HFS+
It seems to me that the problem is with the GPU. Verbose mode stops before this white screen because at that point the system should have switched to graphical mode but something went wrong. Maybe, because the GPU is faulty. 15:24 you should have just pressed "q" 😂
Computer Clan, if you try to boot Mac OS High Sierra off a extr hard drive, you got to take out the inter hard drive because Apple had put a special code where a user cannot have 2 OS on a Mac
Couldn't you have tried booting either your MBP on the other person's MBP or vise versa? I realize that you tried booting off of your external ssd, but couldn't you have given that a shot?
I skipped booting my Mac's internal M.2 on the other party's hardware because I already tried the Recovery Mode, and it failed. I figured it would do the same. Plus, I didn't want to mess with my startup volume by accident.
MacBooks have GPU issues like crazy. I remember on my mothers 2013 MacBook Air the GPU was so goofed it would occasionally just crash the computer at random intervals. I found though that if I just used mini-display port into an external display it would work completely fine even if the computer kept crashing it wouldn’t crash on the external display
the issue is likely that the C9560.Tantalium Cap which is responsible for the power to the GPU that Specific cap need to be replaced with a equal 330µF 2.5v Alu-Organic-Poly Capacitor or even better a 3.0V and then it works like a charm in most cases
You also can boot up into the safe system start by holding shift during the boot screen. In this mode it only loads the necessary kernel extensions. So you wouldn’t need to mess around with the extension files. You also should pay attention to which “repair store” you give it. Because officially it isn’t supported by Apple anymore and some “repair stores” only heat the logic board up or resolder the defective gpu. By doing that you only make it work temporarily but you don’t really fix the gpu. So you should advise the costumer to buy an refurbished one or a newer model.
Also I would NEVER buy a 2011 MacBook pro with dedicated graphics because they all fail and AMD never made a revised chipset so the replacements will also fail
I got my Samsung phone at "recovery loop" and it looped between screen: Installing system update between recovery errors. The errors was: E: failed to mount /efs (invalid argument) dm-verity error E: failed to mount /system (invalid argument) E: failed to mount /cache (invalid argument) but I easily fixed it via flashing new firmware. I have the video how to fix it.

At 14:10 you typed the command wrong, you are supposed to type it as this: /sbin/fsck -fy
Usually if you can choose a Wifi Network it should be possible to go into Recovery mode using Wifi
3:14 damn dat pun...
That's an issue I also have with an iMac. Well, the bar reaches 3/4 before going white, so, I think, that's quite a similar problem
Thankfully on the iMac the graphics are easily replaceable.

If you are in the boot picker you can press Command+R to do recovery mode.
"Siri,how do you reset t.., no Siri, you b**ch, stop, never works" by far, best part of the video.

IIRC if you boot into single user mode, your drive is read only by default. You have to manually remount it read/write.
i wonder... if you upgraded an macbook pro 2015 model to HS, do you still have the bong?
The bong might be muted, but I’m guessing it’s still stored in the EFI (or ROM equivalent) and it could possibly be re-enabled.
so that means you can just jam the bong into the ROM and do a little bada bim and bada boom and it should be on, right?

osama Tliti Well sorry I never tried it on my mac. I knew mac could boot into Windows but I didn't know if Linux was supported
Linux IS a type of unix. So linux actually shares a common ancestor w/ mac os.
you can disable gpu with nvram fa4ce28d-b62f-4c99-9cc3-6815686e30f9:gpu-power-prefs=%01%00%00%00
