iMac not working after restart, multiple functions affected

I restarted my iMac sequoia Version 15.7.2 last night and now nothing works.

I don't have my apple spot where I can see applications, nor my back-up hard drive.

I cannot write in messages, cannot make an alias of a file, cannot put anything into the trash, etc.

What happened?

iMac 27″, macOS 15.7

If a simple reboot of your Mac doesn’t fix things, see if the problem still happens in safe mode.  Safe mode will often correct weird software behavior by forcing the OS to clear caches, do disk repair and other self-maintenance and housekeeping and temporarily disables third-party mods.

TIP - Use a wired USB keyboard for this. If you have the Magic Keyboard, plug that into the Mac with its charging cable.


Does the problems go away in Safe mode? 


You can exit safe mode by restarting your Mac normally, then reevaluate the problem.
