That was an unbelievable save...I lost one weekend plus two days trying to figure out what went wrong when from an error my data was erased and sent back to stone age, at bottom of old version....My apple ID started acting crazy didn't recognize my account, I couldn't start upgrading version from Apple Store, I was stuck in time with that slow version. I tried almost everything, I even contacted the Apple Support team, without success, until accidentally I saw your tutorial and in 5 seconds, my mood jumped from dispare to happiness. Not just I have my version back, I skipped to last possible version allowed to my system, I mean Catalina. Thank you again and God bless you!

For M1 chip macs you don’t need the command r just when you shut down hold the power button until it enters macOS recovery

If you're having trouble booting to recovery, try holding down the key combination until you see the status bar, and not just the Apple logo... sometimes the status bar appears a few seconds later. I've seen Macs boot back to their current OS many times when users don't wait until the status bar appears. Just a tip if anyone is getting frustrated :).

I was having difficulty using Command and R when restarting as it wasn't showing me a drive to install the original OS which was OS X Yosmite 10.10. Turned out using Option, Command and R made my computer look for the most up to date OS for my computer (Mac Air early 2015). macOS Monterey popped and allowed me to select and follow the steps for install. Yay! So simple but took me a while to find the right advice on line.

Any1 else doing this because your mac was laggy

[yamessaves]

I had two options for the OS install to HD, MAC HD, and MAC HD DATA, I chose the first one. Hope I picked right. Haven't seen a single video covering a fusion hard drive where it shown as two, with two options locations for OS install.

How do i unmount a file/disk when it says it is in use?

[blueguest]

Do I need to download drivers again or is that a Windows thing? Also I used Boot Camp and whenever I click restart in OS X it says something like cannot find boot drive or something

I love apple support videos. I just watch them for fun because of how easy it is to watch and the smooth animation. Its kinda like Vsauce
