Target disk mode

My MacBook Air says there's an error with the software update, now it goes to a screen that only gives the option to do a "Target Disk Mode" restart.

But even if I choose this is keeps going through the same cycle and won't restart. Help!

Errors while updating from 11.7.2 Big Sur to Ventura 13.1 or Monterey 12.1 macOS Big Sur Version 11.7.2 MacBook Pro (16-inch, 2019) 2.6 GHz 6-core Intel Core i7 16 GB 2667 MHz DDR4 Intel UHD Graphics 630 1536 MB I have been trying to complete the newest software update. I have not been updating regularly which I am assuming may be one of my problems. I tried to upgrade to macOS Ventura 13.1, which is what shows when I got to software update in system preferences. I get this error every time I attempt the upgrade. I have restarted, restarted in safe mode, as well as tried to reinstall the Mac OS from recovery mode. None of it works. Always the same result. I have used WiFi and ethernet. I've scoured this board to try and find a fix. When I am try it in recovery mode it gives me this status bar screen: But doesn't move from that. It stays "about 2 hours and 21 minutes remaining" for about 20 minutes and then it gives me this error: I tried to move from Big Sur to Monterey thinking that perhaps I needed to go from 11 to 12 before 13. This is the error I get when I try to upgrade to Monterey: “The operation couldn’t be completed. (PKDownloadError error 8.)" I'm not sure what is wrong and I would love any advice on how to fix this. I appreciate any help! Thanks!

"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.

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!

Target Disk Mode basically turns a Mac into an external disk drive that, in theory, you can connect to another functional Mac to be able to access its contents.

I am assuming that you tried starting your Mac in Recovery Mode and were unsuccessful doing so ... correct?
