Prepare Your Mac for Update
Check Compatibility and Storage
Before installing a Mac operating system update, verify that your Mac model supports the new version and that you have enough free storage. Apple lists compatible Macs on each update page, and macOS typically requires several gigabytes of available space.
Back Up Important Data
Use Time Machine or another backup method to create a current copy of your files. Backing up protects you in case something goes wrong during the update and helps you recover apps, settings, and personal data quickly.
Install macOS Update from System Settings
Access Software Update
Open System Settings, click General, then select Software Update to see available updates. The system checks for the latest macOS version and any pending security patches.
Review and Install
If an update appears, review the details, accept the license agreement, and choose Install Now. Keep your Mac plugged in and avoid interrupting the process to prevent issues.
Update Using Recovery Mode
When Standard Updates Fail
If the Mac App Store or Software Update does not start the installation, restart your Mac and hold Command-R at startup to enter Recovery Mode. This method downloads the latest compatible macOS version from Apple servers.
Reinstall or Update
Choose Reinstall macOS from the Utilities window and follow the prompts. Recovery Mode is also useful for erasing the disk, reformatting, or troubleshooting installation errors.
Manage Update Settings
Control Automatic Updates
In Software Update preferences, you can turn on Automatic Updates to keep your Mac up to date without manual checks. You can schedule installations and decide whether to install system data files and security updates automatically.
Pause or Defer Updates
If you need a break from updates, you can pause macOS updates for a few days or weeks. This is helpful when working on important projects or using specialized hardware that requires a stable environment.
Maintain Long-Term System Health
- Check for updates regularly and install security patches promptly
- Keep sufficient free storage before starting an update
- Back up with Time Machine or an equivalent solution before major updates
- Use Recovery Mode when standard installation methods fail
- Review update notes to understand new features and known issues
- Defer noncritical updates if you rely on specialized hardware or software
FAQ
Reader questions
Will updating macOS delete my files and apps?
No, updating macOS does not delete your files and apps. It installs the update in place while preserving user data, but you should still keep regular backups to protect against unexpected issues.
What should I do if the update fails halfway through?
If an update stalls or fails, restart your Mac, reconnect to power and Wi-Fi, and try again. If problems continue, use Recovery Mode to reinstall macOS without losing your personal files.
Why does macOS ask to reinstall the same update repeatedly?
Repeated install requests can happen if important files were changed after the update or if system components did not update correctly. Running Software Update again or reinstalling macOS usually resolves this.
Can I choose which features to update and which to keep?
macOS updates are delivered as full system packages, so you cannot select individual features. You can, however, test new releases in a beta channel or delay major updates until you are ready to adopt them.
