Let’s get started!

2. Install the Update in Safe Mode

- Once in Safe Mode, try running the macOS update again to check if it completes without freezing.
3. Skip the Update During Setup

4. Restart the Update
- If you’re sure the update is frozen, refresh it by holding the power button for 30 seconds until the Mac shuts down.
- Press the power button again to restart and continue the update process.
- You can press
Command + Lto check the estimated installation time.
5. Give the Update Some Time
Large updates can sometimes take a while to complete. Keep your Mac plugged in and allow the update to run for a few hours before concluding that it’s stuck.
6. Reset macOS Software Update
Update Services helps keep your computer up-to-date with the latest patches and security updates. Whenever you experience a freezing issue with the new macOS update, just reset the update services. This may help solve the problem.
To reset software updates on Mac,
- Open Finder and enter the path
~/Library/Preferences/ - Find the file called ‘com.apple.SoftwareUpdate.plis‘ and delete it by moving it to the Trash. If you also spot a file with the same name but ending in ‘.apple‘ (such as “com.apple.SoftwareUpdate.plist.apple”), remove that one as well.
- Restart your Mac
OR You can use below Terminal commands to reset the update service:
sudo rm -rf "/macOS Install Data"
sudo rm /Library/Preferences/com.apple.SoftwareUpdate.plistAfter running these two commands, restart your MacBook. The next time you check for updates, macOS will automatically generate a new preferences file to replace the one you deleted.
7. Use Recovery Mode
If the update still won’t finish, try reinstalling macOS through Recovery Mode. Don’t forget to take a backup of your data before performing these steps.
- Power off your Mac, then restart it while holding Command + R to enter Recovery Mode.
- Choose “Reinstall macOS” and follow the instructions to download and install the latest version.

Following these fixes, you should be able to resolve most issues you encounter with freezing when trying to complete macOS updates.
A Genius Thought
When a major OS update is released, it’s wise to exercise caution. Instead of updating immediately, consider waiting for a subsequent minor update that addresses any potential bugs.
For example, waiting for macOS Sequoia 15.1 or 15.2 can help ensure a smoother upgrade experience.
