I have a serious problem with my 2017 iMac running macOS Catalina BETA. After a normal reboot the iMac loaded until the bar reached 100%. Then for hours nothing happens, it just stays at 100%.
The things I tried:
- Boot in Safemode – still hangs on 100%, can’t access Safemode
- Reset NVRAM/PRAM – nothing happened
- Reset SMC – nothing happened
- Run First Aid on all disks – helped and discovered nothing
- Uninstalled Google Chrome update in terminal – nothing happened
- Tried to reinstall MacOS Catalina – not enough space on my disk
- Tried these commands:
cd /Volumes/Macintosh\ HD/var/db/caches/opendirectoryandmv ./mbr_cache ./mbr_cache-old– “no such file or directory” - Tried to boot in startup manager – still hung on 100%
- Tried to run the Apple diagnostics – it said everything is fine
- Single user mode with commands like
mount-uw /– command not found - Let the iMac sit for a couple days – still hangs on 100%
And so on…
So, as you can see, I tried many things and nothing helped. Do you have a good solution or a advice/suggestion without erasing the disk?
Best Answer
Apple has a very good triage step that I follow even after doing a very good job like you in trying to eliminate things (or hope for a quick fix)
Why not start down that path and this evening make a good last backup so you can proceed where it says erase and start over?
