How To Use Safe Cleanup in MacKeeper

The Safe Cleanup feature detects the junk files in your system and can do a Mac cleanup in a click.


If your Mac is running out of disk space or you see the ‘Your startup disk is almost full’ message, you can free up megabytes or even gigabytes of space without removing any personal files.


Just start the Safe Cleanup scan and remove junk files from your Mac quickly and easily.

How to scan Mac for junk files

Junk files can take up valuable space on your Mac and weaken the performance of your device over time. Fortunately, it is simple to scan for and identify junk on your Mac.


1. Open MacKeeper, select Safe Cleanup from the left sidebar, and click Start Scan

  • Logs
  • Caches
  • Trash
  • Languages
  • Mail attachments

What are junk files?

MacKeeper divides junk files into six categories. Below you can find a brief description of each.

  • Logs are files that keep records of various events in macOS system, like system and app notifications, error messages, information about incoming connections, etc.
  • Caches are temporary files that are created by the system. Cached files, especially browser caches, can pile up and waste a lot of your system space.
  • Trash are files that have been removed by the user and placed into Trash.
  • Languages are unneeded localization files for applications that support multiple languages. Apps are often equipped with localization files, so that customers from different countries can use the app in their native languages. Usually, a customer needs only one preferred language, so the others can be removed to make the Applications folder more lightweight.
  • Mail attachments are files sent to your inbox that are stored locally on your Mac. You may have quite a lot of attachments if you use the Apple Mail app, so you can free up some space by removing the stored email attachments.


All categories are selected by default, so MacKeeper scans and detects files from all of these groups.

How to remove unneeded files from Mac

Once the scan is done, you can perform a Mac cleanup. Before removing files, you should check the details about the files you’re planning to delete.


1. Select a category from the scan results list, and review the details to the right

Does MacKeeper remove files automatically?

MacKeeper doesn’t perform your Mac cleanup automatically since removing some files requires your confirmation.


However, MacKeeper performs Safe Cleanup scans automatically every 24 hours.  If something critical is found in your system, MacKeeper notifies you, so that you can start your Mac cleanup manually.


If you would like to turn the automatic scan off, follow the steps below.


1. Open MacKeeper, and click MacKeeper next to the Apple logo, then select Preferences

2. On the Regular Scan tab within the Preferences window, deselect the checkbox next to Automatically scan my Mac every 24 hours
