2019 iMac not booting

Recently, I was using my iMac, then I accidentally unplugged it after dropping something. After that, the iMac would refuse to boot whatsoever, staying stuck on the apple logo. I tried whatever I could in recovery, such as reinstalling MacOS on top of my data (which is safe when I checked in the terminal), first aid on the drive, try to make a bootable drive, and trying to boot using safe mode. Whatever I did, nothing worked, and doing verbose mode using Command+V wouldn’t work, and target disk mode wouldn’t work as well with my M1 MacBook Air, since it wouldn’t even start in target disk mode, it would just stop loading. Eventually, i used nvram boot-logs”-v” to enable verbose mode in the terminal, and it worked, showing all the logs, this is what I summed it down to.


AppleKeyStore: operation failed (sel: 7)


unexpected session uid: 0 requested by: AirPlayXPCHelper


AirPlayXPCHelper (163)


and, as memory can serve, something about disk1s1 (aka my disk) not being able to be read.


Please help me. Thank you.

Try booting into the Recovery volume (boot with the Command + R keys held down  - Intel Macs) or  (How to Boot an M1 Mac into Recovery Mode), select and run Disk Utility's Repair on all available volumes. Then reboot normally.


If that fails to fix the problem reboot into the Recovery volume and reinstall the system. The user data is not affected. But, as with any major event, be sure you have a current and full backup with Time Machine.
