How to Remove Log Files on Mac

What Causes This?

macOS and the apps you use constantly create log files to record errors, updates, crashes, and background activity. Over time, these files can build up in system and user Library folders, especially if an app is misbehaving, crashing often, or generating excessive debug logs. Most log files are harmless, but old or oversized logs can waste storage space and make it harder to find useful troubleshooting data.

Common Symptoms

• Your Mac is low on storage space for no obvious reason
• The Logs folders in Library contain large or growing files
• An app keeps creating new crash or error logs
• System Data or Other storage appears unusually large
• You want to clear old diagnostic files before troubleshooting again

How to Fix It Manually

1. Check your available storage first

   1. Click the Apple menu > System Settings.
   2. Go to General > Storage.
   3. Wait for macOS to calculate disk usage and confirm that storage is running low.

2. Open your user log folder

   1. In Finder, click Go in the top menu bar.
   2. Select Go to Folder...
   3. Type:

      ~/Library/Logs

   4. Press Return to open the folder.

3. Delete unnecessary user log files

   1. Look for large folders or old logs from apps you no longer use.
   2. Common examples include crash reports, installer logs, and app-specific debug logs.
   3. Move unneeded files to the Trash.
   4. If you are unsure about a file, leave it alone rather than deleting it.

4. Check the system log folder

   1. In Finder, use Go > Go to Folder... again.
   2. Enter:

      /Library/Logs

   3. Review the contents carefully.
   4. Delete old installer logs or logs from removed third-party apps.
   5. You may be asked for your Mac administrator password.

5. Clear crash reports if needed

   1. Open Go to Folder... in Finder.
   2. Check these locations:

      ~/Library/Logs/DiagnosticReports

      /Library/Logs/DiagnosticReports

   3. Delete old crash reports you no longer need for troubleshooting.

6. Empty the Trash

   1. Right-click the Trash in the Dock.
   2. Choose Empty Trash.
   3. Restart your Mac afterward so macOS can recreate any log files it still needs.

7. Use Terminal only if Finder won’t remove the files

   1. Open Terminal from Applications > Utilities.
   2. To view your user logs, run:

      du -sh ~/Library/Logs/*

   3. To remove a specific file or folder, use:

      rm -rf ~/Library/Logs/folder-name

   4. Be very careful with rm -rf. Deleting the wrong folder can remove important data.
