Your Mac software update is stuck downloading or installing
A stuck update is almost always caused by a slow internet connection or your Mac running out of storage space. Restart your Mac to try the update again, make sure you have at least 20 GB of free space, and confirm your internet is stable — this fixes it for most people.
macOS updates are large files that need to download and install. If your internet keeps dropping, your Mac runs out of space, or the installation gets interrupted, the update gets stuck. The quickest fix is to restart your Mac and try the update again. Make sure you have enough free storage space and a stable internet connection before you start.

Skip — I just want a technicianCommon mistakes to avoid
- Interrupting the update by restarting during installation — always let updates finish completely before restarting
- Not checking storage space before starting an update — if your Mac is full, the update will fail
- Assuming the update is frozen when it is really just slow — large updates can take 20-30 minutes
Signs you need professional help
- You have waited 30+ minutes, freed up storage, and the update is still stuck
- You see an error message with a code like -43 or SSL error
- Your Mac restarts but still shows the update screen over and over without completing
