Hi,
If you don't have enough storage space to upgrade your Mac's operating system to the latest version, here are some solutions to the "not enough space to install macOS" error message.
1. Optimize your storage disk
2. Clean out system junk
3. Delete iPhone and iPad backups
4. Uninstall unused apps
5. Clean up the Downloads folder
6. Store on iCloud
7. Upgrade from external drive
8. Use a third-party cleaner
9. Wait for a new installer
It's infuriating to become stuck while upgrading your Mac. Even more so if the cause is a lack of storage space; in general, you should keep at least 64GB free to allow your operating system to function properly and everything to run smoothly.
So, the best way to proceed is to clear out some files and trash. The tips above will undoubtedly assist you in getting back on track with your macOS upgrade, and we recommend cleaning out the trash once or twice a month to keep everything organised and to avoid trash pileup.
With that said, we have reached the end of our guide today, and we hope that you can now effectively clean your Mac and upgrade it without errors.
Thanks
