Symptom: My IMac 5K (Ultimo 2014, Monterey) always freezes for a short time, i.e. no matter if I briefly open the Finder, select folders or open a setting, then the ball icon always appears for about 1 minute or less, so it is not app, folder specific.
Analysis: My guess is, it's the hard drive problem so I ran Disk Utility and did a first aid check. The apps found several permission errors, however the app does not repaired it. In OSX system > Disk Utility > Disk and Container selected > First Aid started. There are also no error messages in the system logs that would match to the freezing time.
- Start Disk Utility via CMD+R: It doesn't happen, the screen stays black. I read that the partition is damaged or not present, that's probably why it doesn't appear.
- Reinstall via Internet CMD+Alt+R: It loads, but later I receive the error 2003f appears (network problem). Then I connect the iMac directly via LAN and then I receive 1006F. I execute Command + Option + P + R performed, then the installation progressed and I received 2003F again.
- Created bootable USB stick: I thought the connection to the server seems to be unstable, so I created a Bootable USB OSX Monterey (using a Mac mini Intel). When booting, I pressed ALT and selected the installation, then a crossed out icon appears, although the system is compatible with the Mac and the installation is also bootable from another Mac.
I don't know, how to fix the problem with the iMac. Maybe the hardware is broken, because I got a 1006F error... Maybe one more has an idea how I can fix the problem. Thanks a lot for the help.
