I just recently sent my old early 2009 Mac mini back to Apple for recycling. I had El Capitan installed so I booted into recovery, ran disk utility and did a 7-pass erase of the Macintosh HD volume.
We just boxed up my old Mac and it heads to charity Monday! This video was a big help. I encrypted (pre T2) and I feel so good knowing it's as good a job of cleaning that ssd as I can do. You even found the Apple guidelines for everything else and I appreciate that. Many Thanks
One important piece of information is missing in the video: Even on the M1 Macs it's necessary to enable FileVault because the "standard" encryption is easily bypassed. Search for "Built-In Mac SSD Encryption Is Easily Bypassed by an Attacker With Physical Access if Filevault Isn't Enabled" to get more info.
I always make sure I have both an external hard drive and cloud backup prior to wiping/reinstall op sys. But that is just me. Typically I’m upgrading to a newer Mac (even MS software or Linux). Simplifies the new setup.
Excelente as always. I'm anal when it comes to wiping a computer I'm selling as I understand the risks of identity theft. What your video did was provide me with greater comfort that stealing data from an erased drive with a fresh OS installation would be a specialist activity that would be unlikely to be worth the effort.
1. Erase from recovery disk utility 2. Create a new account again and enable file vault 3. Open terminal 4. Run 'dd if=/dev/random of=rnd bs=1M' This would write random data to the encrypted disk. You could do this multiple times. Totally unnecessary though. Great video!
Before getting rid of your old Mac, use it to try out all the cool things Gary explains how to do. Many people never get more capable on the use of their Mac because they don’t want to risk messing up their work and then needing to spend time and effort to get back to where they were before they messed up. That older Mac is still likely relevant so it can be your discovery tool without consequences. Get your older family members more computer savvy in this way.
I may end up watching this video again at some point in the future, as i plan on getting an M1 Mac Mini (base model with 8GB RAM and 256GB SSD) as a temporary Mac until i am able to get a Mac Studio, or whatever i decide to get And then the Mac Mini may either go to a relative (i know that 256GB will be plenty of storage for them, one of the windows laptops they have has only 64GB of eMMC storage), or it may get sold
Does Apple have this kind of info on their website or YT channel? They should have an entire webpage and YT videos dedicated to this to help protect people. The info should be simple and easy to access with helpful photos and videos of the process. This should be easy for us.
As mentioned at 6:20 Turning on File Vault after the fact is an odd suggestion. You have no guarantee that the new encrypted files would overwrite the original unencrypted files. You might think and feel more secure doing this but if you were in a situation where you really needed to make sure your data is fully gone this is not a good suggestion.
Note that current Macs (T2) and newer already encrypt the entire drive, even without FileVault. (FileVault just adds the protection of needing your login password to access the data).
Hi Gary, I tried to reset my M1 MacbookPro have managed to delete something I shouldn't have, now I get the Exclamation Mark in a circle with a link to apple Restore. Could you possibly make a vid on how to restore an M1 MacbookPro using another computer with a data link and Apple Configurator? Going bananas here...
In the case of the M1 situation what about external hard drives that had been formatted in the disk utility? Are those also encrypted by default? If not, then what way should I erase the drive to be secure?
Pretty much knew this but still great as an extra reenforcement and a great video to save for future reference. not even sure what i did with my old Hewlard Packard back in 2012 thats when i got my first MacBook pro that i am still using. excited for my new 2021 MBPro to arrive next week supposedly, i ordered it 6 weeks ago it is due to arrive the 4/ 22 to 4/29. just got pushed out to 6/6 to 6/21 what i bought is 16" MBPro M1 Max with 32 Ram and 2 TB storage, hope to have it 10+ years without worrying about software and app upgrades or space. In 2012 i bought my 2012 MBPro 8GB Ram was biggest & i got it with 1TB Storage which was huge back then. I only have only used 592.92GB storage since 2012, the new one for me should be plenty big, although im almost thinking i should have got 4TB as i want to move that 600GB to the new 2021. As mentioned above, I'm still on a 15" 2012 MBPro, the 2021 MBPro M1 Max is actually lighter, slightly smaller with a larger screen. Excited for my new 2021 MBPro to arrive next week supposedly, i ordered it 6 weeks ago it is due to arrive the 4/ 22 to 4/29 just got delayed until 6/6/ to 6/21. what i bought is a 16" MBPro M1 Max with 32 Ram and 2 TB storage, hope to have it 10+ years like my 2012 MBPro without worrying about software and app upgrades or storage space.

As mentioned above, I'm still on a 15" 2012 MBPro, the 2021 MBPro M1 Max is actually lighter, slightly smaller with a larger screen. THE 2021 is 19/64 inch thinner, 11/32 inch narrower, 3/64 inch less depth and 13/16th of a pound lighter with a 13/16" inch larger screen. The new 2021 compared to my old 2012 is basically slightly more than a 1/4 inch thinner, slightly less than 3/8 inch narrower, slightly less than a 1/16 inch front to back, slightly more than a 3/4 pound lighter with slightly more than a 3/4 inch larger screen. And they brought back the ports that i like and mag safe that i love. It is a win win for me. With all he improvements and bring backs it could not have been a better model, year and time to upgrade!! Absolutely Psyched!!!
HI, Laptop with soldered in C drive- Windows , How do i erase the C drive if i need the operating system on it to do it and its all being erased? I have USB stick with ubuntu on it if that helps. If i do a fresh install, it only has option for delete not ERASE when you what to start fresh. Thanks
Hey Gary, would you please provide me with your take on software updates on MacBooks or refer me to the video in which you do so? I have a 2021 macbook pro and would like to maximize its lifespan. I fear that, although today’s updates may be optimized for my computer, this will not always be the case, and such updates will be increasingly less beneficial and/or more negative. Thank you Gary.
I always use the current version of macOS and all apps. Apple adds new features with each version of macOS. You pay for those when you buy a Mac. Why turn those down and keep your Mac set in the past? New versions also include optimizations that could make your Mac faster too.
Thank You!! What about an older iMac with a spinner that won't mount? I can't access it at all. Even though I can use the iMac by connecting an external drive with OS Sierra installed, the internal drive is not seen. Can I just send the iMac to Apple to be recycled as is? Its an intel core 2 duo ...
If you can't mount the drive, there's nothing you can do to erase it. The super-cautious would open it up, remove the drive, and take it to a data shredding company to be shredded (they can do hard drives). But it is very unlikely anything will happen if you just take it to recycling.
Very helpful information. I have been anxious about it. I lost my 2012 iMac during a property dispute and i always wonder whether my data stayed safe or not. Before i had lost it though, coincidentally it wasn’t booting up n there was problem with the fusion drive. I was told to reformat the drive which i didnt do.. so most probably the drive’d hv been safe. My another question is, without having my osx password or appleid password, how easy is it for someone to reuse that imac. I haven’t heard from it within “find my”…. Isnt there any mechanism that stops any stranger to reset the imac n use it as new?
On a 2012 model someone can always wipe the drive and reuse the Mac (but then they get a 11-year-old Mac for their efforts). With newer Macs, you can prevent this with Activation Lock. See support.apple.com/en-us/HT208987
Hi Gary just a few more questions. I have three older iMacs that need to go because I am selling my home and moving into a rental condo. My first one that I bought was in 2007, so I did what you said in the video and did the security pass at the highest level and I think it took a minimum of 12 hours or so. That’s the one that came with two disc that you would load in the side and I have everything that came with that in the box. I guess I should keep the keyboard because it’s a plug-in which is always nice to have. I’m feeling that one is ready to be taken to either Best Buy or Apple to get that off my hands because no one will buy that from me. Not sure if I trust Best Buy, an article years ago where they replaced a hard drive for someone and about three months later a guy in another state notified the owner of the old computer/hard drive that he just installed that hard drive in his computer and all the information was still on there. That made the newspapers back then. My other two iMacs are from 2013 which I think works great as a second monitor, but I’ll never use it because of lack of space, but I hate to just have it destroyed as well. Can still surf the Internet and everything else on that. But I have deleted everything and it’s in the box. :-) Now, the third iMac is the first one with the “ fusion drive“ from 2015 I believe? I’m assuming I would just delete that the same way as the older ones with the security wiping it clean for lack of better words. I don’t think I could get anything for that even though it’s working fine, but it is slow as a dog. I’m done with big computers. Last but not least I am either going to sell or trade in my MacBook Pro 2017 15 inch with a 256 GB solid-state drive. The thing that kills me about this… As I wound up talking to a great senior advisor at Apple about the battery giving me some problems and I caught him on a good day and even though my AppleCare is long expired on it, he had a box sent to me and I was able to send it to Apple and they replaced the battery for free! To make this even better they sent me a text message and told me they found something they didn’t like something on the logic board and they also replaced the whole logic board so basically it’s a new computer, right? This was just done by Apple in January of this year 2022. Best Buy is offering me $425 for a trade-in on a new one or just a gift card for $425. I would think I could definitely sell that on craigslist for at least $600? I know you’re busy and I always ask you these long questions. I was a supporter of your channel monthly and plan to do that again after I sell my home and get situated with retirement. Any feedback would be helpful from you. Also, any comments from other viewers of this, would be welcomed. Thanks so much. I am a nutcase when it comes to security. Here’s a final question I just thought of… What about thumb drives going back to 2005? I must have 20 of those!:-) I know you’re loving Ness. Thank you.👍🏻👍🏻
Sounds like you have kept everything in mind here. Selling on Craigslist and the like could get you a higher price, but also means you have to deal with scammers and annoying people (that just don't show up or try to change the deal at the last minute, etc). You can erase those USB drives, and then just destroy them. Don't waste too much time on them is my advice.
@@macmost Thank you Gary. Years ago are used to sell all my Mac products on craigslist… It truly is a pain in the butt. I think I’ll just trade in the MacBook Pro 2000 1715 inch to Best Buy. Thanks again. If I can just stick those USB drives into my laptop and erase them then toss them that would be great. I’ll give that a try this evening or tomorrow. Thanks again, so true about wasting time especially when I’m getting ready to sell my home. Take care.
Much too wordy to follow the mass of information. I don't know how to access apple's site and if I did how to find on there the facility you mention to do the drive erase and factory reset. All much too complicated. A reset button with a pin would be a much more useful option. My next option is to put a 9lb club hammer through the Macbook 13 and take it to the tip !
@@activate-motivation You do. Just a normal erase. You see the data is encrypted on the internal drives on all MX Macs. Once you erase, any bits that could be recovered would just be encrypted "mush" without any way to piece together or decrypt. Think of it as being completely irrevocably scrambled and randomized.
This was PERFECT! I love the in-depth explanation of formatting. Nice job and thank you!

In the case of the M1 situation what about external hard drives that had been formatted in the disk utility? Are those also encrypted by default? If not, then what way should I erase the drive to be secure?
Not necessarily. Use Disk Utility to check. You can also encrypt them using DU.

How can u wipe the hard drive with out being able to log in on the computer?
Hey Gary, I just upgraded my old drive on my macbook pro to an ssd. Somewhere i heard i need to make sure TRIM is turned back on. What's your opinion?
Not something I've ever done so can't advise you there, sorry.
6:56, so why didn’t Apple just remove FileVault on these Macs? Seems pointless if your data is already encrypted.

You should always secure wipe your device before you give it away … no excuses
I just yank out my old drives; destroy them... and sleep tight.
Worked in the old days, but now SSDs are attached to the board. Plus, you can't resell it (and in some cases you can't recycle either).

Your Mac Mini's drive is an SSD and it is encrypted. No need to secure erase. A normal erase means that the data is unrecoverable.
