iMacs are great devices, but even great devices can encounter issues. Speaking of which, many users reported that their iMac is stuck on the loading screen with an Apple logo.
This can be a big problem because you might not be able to access your files at all. However, there’s a way to fix this.
What can I do if iMac is stuck on loading screen / bar / Apple logo?
1. Use the Terminal
- Turn on your iMac and press and hold Command + S.
- When the Terminal opens, run the following commands:
mount -uw /
- After running these commands, check if you can boot to your system. If not, repeat the first two steps, but run these commands instead:
mount -uw /
mv /Library/Extensions/*.kext /
mv /Library/LaunchAgents/*.plist /
mv /Library/LaunchDaemons/*.plist /
If you manage to boot back to your computer, try removing all third-party applications, since it’s highly likely that third-party software is causing this issue.
Alternatively, users are suggesting to run the following commands in the Terminal:
cd /Volumes/Macintosh\ HD/var/db/caches/opendirectory
mv ./mbr_cache ./mbr_cache-old
Many users reported that this set of commands worked for them, so be sure to try them.
2. Disconnect USB devices
- Turn off your iMac.
- Disconnect all USB devices from it.
- Now try to start your iMac again.
Few users reported that they had a problem with an external hard drive, but after disconnecting it, the issue was resolved.
3. Use the Time Machine feature

- Restart your Mac and press and hold Command + R while it boots.
- Select Restore From Time Machine Backup.
- Follow the instructions on the screen and select your source as well as the desired backup.
4. Format the disk and install macOS again

- Restart your Mac and while it boots press and hold the Command + R
- Once the Apple logo appears, release the keys.
