Accidently deleted Macintosh HD on Disk Utility - now my mac won't start up Earlier today I was trying to reset my Macbook Pro (2016 model on MacOS Big Sur) to sell and I deleted Macintosh HD from the Disk Utility software thinking that it would reset my mac to factory settings. Now my Mac can't start up and shows a folder with a question mark in it. First Aid does not work for any of the internal options. "Preboot", "Recovery" and "VM" are unmounted every time I go back in to Disk Utility. First Aid for Internal > AppleAPFSMedia does not work and says I need to repair the startup volume by running First Aid from Recovery? Isn't that what I'm doing? When I try re-install MacOS it only shows "Macintosh HD - Data" & "Update" and the installation always fails when reaching the end on either option. Attached is a photo of my Internal disks on Disk Utility. I would appreciate any help, thank you in advance!

"The file can't be found." on booting... Everytime I start my MacBook Pro (intel chip), I get two error message. Both say "The file can't be found". This has been happening ever since I updated to big sur. I have to click on "OK" (twice) to make them go away. Neither does it tell you what file can't be found. I just updated to Ventura 13.1 and the problem remains. As does the control strip/touch bar issue. Is Apple going downhill...SMH.

Most likely yes: Contact Support to determine repair options.

I already started the disk utility to repair and then I restarted the mac - Didn‘t solve the problem. Even when i reinstalled the macOS from recovery mode the problem still remains... what do you mean, defect hardware?

That Mac is having difficulty reading or writing to its startup disk. Restart your Mac in macOS Recovery mode, and use Disk Utility to repair it:

Repair a storage device in Disk Utility on Mac - Apple Support

That "repair" may or may not be successful.
