Resolving High CPU Usage by mediaanalysisd on Older MacBooks Running Monterey

Step-by-Step Solution for High CPU Usage by mediaanalysisd on MacBook7,1

Target Audience: Intermediate users comfortable with macOS, OpenCore Legacy Patcher (OCLP), and basic terminal commands.

Step 1: Understand mediaanalysisd

• The mediaanalysisd process is related to analyzing media for features like Memories and facial recognition in Photos.
• High CPU usage can occur when it's processing a large media library or encountering corrupted files.

Step 2: Update Your System

• Ensure your macOS Monterey is updated to the latest version.
• Update OpenCore Legacy Patcher to the latest version as well.

Step 3: Monitor and Identify

• Use Activity Monitor to confirm that mediaanalysisd is the process causing high CPU usage.
• Identify if the high usage is constant or spikes periodically.

Step 4: Check Your Media Library

• If possible, temporarily move your media library (especially Photos) to another location or drive. This helps in identifying if the issue is related to media file processing.

Step 5: Disable iCloud Photo Library Temporarily

• If you use iCloud Photo Library, try disabling it temporarily to see if it reduces the CPU usage.

Step 6: Clearing Photo Library Cache

• Navigate to ~/Pictures/Photos Library.photoslibrary in Finder.
• Right-click and select 'Show Package Contents'.
• Locate and delete the com.apple.mediaanalysisd folder to clear the cache.

Step 7: Safe Mode Check

• Reboot your MacBook in Safe Mode (hold Shift during startup) to check if the issue persists. This can help rule out third-party software conflicts.

Step 8: Terminal Commands

• If comfortable with Terminal, use commands to disable or limit the mediaanalysisd process:
  • To disable: sudo launchctl disable system/com.apple.mediaanalysisd
  • To limit: Adjust CPU priority using the renice command.

Step 9: Create a New User Account

• Test by creating a new user account on your MacBook. If the issue doesn't occur on the new account, the problem might be user-specific settings or files.

Step 10: Backup and Reinstall

• As a last resort, back up your data and consider a fresh installation of macOS Monterey.
