Why clean up a Mac

Even if you have enough free space on your Mac, you should regularly clear junk files, which might make your Mac run slowly. Nothing is worse than a slow computer.

Junk files consist of caches, cookies, the leftovers of already removed applications, unneeded installation files, duplicates, and so on. Most of these files are absolutely useless and they can and should be safely removed.

Also, we recommend that you check your Mac carefully and make sure that there are no remaining files of the applications you have already uninstalled. Some applications might spread their files all over the disk. For your Mac’s security, as well as general performance, it’s important to find and remove such files. Keep on reading to find out how to find and remove applications’ leftovers.

Steps to Clean up a Mac

1. Clean up caches and logs

Mac keeps cache files created not only by the browser but also by the system and applications. By default, caches are stored in the ~/Library/Caches folder. Here is how to clean up the Cache folder:

  1. Open finder.
  2. Go to the Finder’s menu → click on Go → select Go to Folder…
  3. Type ~/Library/Caches in the appeared search field and click on Go.
  4. You will see the Cache folder which contains subfolders with the cache files of all applications on a Mac. By removing these subfolders, you clear caches of these applications. Finder window showing the Caches folder
Note: Don’t remove the folders which contain com.apple in their names. Removing important system files can damage the system.

To remove logs from your Mac, the process is nearly the same, but you’ll have to find the Logs folder. Open finder and navigate for the following location:

~/Library/Logs

2. Delete installation files

You can install applications on Mac by downloading them from the App Store or by downloading their installation files right from the developers’ websites. These installation files (.dmg files) are needed only once when installing the apps. However, most users then forget to remove them, and they start to clutter the Mac’s hard drive. By default, files you download get saved in the Downloads folder on Mac, but you could also save them in other locations.

Here is how to find and remove DMG files on Mac:

  1. Open Finder.
  2. Type “.dmg” in the search field and press Enter.
  3. Sort files by Kind and you will see the list of all .dmg files on your Mac.

3. Remove email attachments

If you use the standard Mail application on macOS, you should know that the system saves all attachments in a separate folder on the hard drive. In just a few months of work with your mail client, the folder size can grow to several GB. You can find this folder using the Spotlight search. Just type “Mail Downloads” in the Spotlight search field and press Enter to open it. Then, select and remove all unneeded attachment files from the Mail Downloads folder.

To solve this problem we highly recommend that you use the Pro tool from MacCleaner Pro bundle: Disk Space Analyzer.

6. Remove duplicate files

Finding duplicates on Mac manually is not that simple. iTunes provides an option to find duplicate music, but when it comes to finding duplicates of other types of files on Mac, this can be too complicated. You can use the Smart folder to manually find duplicates on Mac, but the better way to do this is to use a special tool called Duplicate File Finder. This tool is included in the MacCleaner Pro bundle as well.

9. Empty the Trash

This tip might sound very simple, however, most users forget to clean up the Trash! So please, especially after ridding your Mac of all types of junk files, don’t forget to empty your Trash!
