Updating Your Mac OS:

1. Access System Preferences > Software Update.
2. If an update is available, click "Update Now."

This usually suffices. However, occasional errors like "macOS installation couldn't be completed" may occur. Let's explore solutions.

Why Won't My Mac Update?

Troubleshooting starts with your Mac's model. Newer macOS versions may not support older, less powerful machines. Check compatibility requirements (e.g., for macOS Monterey).

Beyond compatibility, other causes include poor network connection, insufficient disk space, or Apple server issues. Let's address these:

Monterey-Specific Problems:

• System bricking: Some Intel Macs (especially those with T1/T2 chips) and even M1 MacBook Pros have experienced bricking. Professional repair may be necessary.
• App memory issues: The "out of application memory" error might require force-quitting apps and restarting.
• SD card reader problems: Some SD cards may malfunction with 2021 14/16-inch MacBook Pros (awaiting an Apple fix).

Big Sur Problems:

Big Sur users often faced disk space issues. Ensure at least 20GB of free space before updating. CleanMyMac X can help clear unnecessary files. Network problems ("update package deleted") can also occur.

Pre-Update Optimization:

System clutter can hinder updates. CleanMyMac X optimizes your Mac before upgrading.

Check Apple's System Status:

While rare, Apple server issues can affect updates. Check apple.com/support/systemstatus for the macOS Software Update status.

Network Connection:

A weak WiFi connection can cause problems. Test your internet speed (speedtest.net). Consider using Ethernet for better stability. NetSpot helps optimize your WiFi network.

Restart and Retry:

Sometimes, a simple restart of your Mac and the update process resolves the issue.

Alternative Update Methods:

• App Store: Major macOS version updates (e.g., Catalina to Big Sur) are available in the Mac App Store.
• Apple Support Website: Incremental updates (e.g., 10.15.3 to 10.15.4) can be downloaded from support.apple.com/downloads.

Automatic Date and Time:

Incorrect date/time settings can interfere. Ensure "Set date and time automatically" is enabled in System Preferences > Date & Time.

Safe Mode:

Safe Mode disables interfering processes. Instructions for Intel and M1 Macs are provided in the original article.

Reset NVRAM (Intel Macs only):

Resetting NVRAM (Command Option P R during startup) clears stored settings. M1 Macs handle this automatically.

Reinstall macOS in Recovery Mode:

A last resort: Reinstalling macOS in Recovery Mode (instructions for Intel and M1 Macs provided). Use Disk Utility to erase your hard drive before reinstalling to prevent future errors.

Backup and Restore:

Regular backups are crucial. Get Backup Pro offers comprehensive backup solutions, including incremental backups and cloning.

Mac Optimization:

CleanMyMac X optimizes your Mac's performance, potentially mitigating update issues on older machines.
