4. Clear cache

In addition to junk files, deleting files manually can leave behind system cache files. Cache files are temporary system files created by OS X Yosemite to speed up your Mac’s performance by storing the files it knows you’ll need again. However, they can be counterproductive over time and therefore need to be deleted during a cleanup session.


To delete cache files on macOS Yosemite:

  1. In Safari, go to the top menu bar, click Safari, and select Clear History.
  2. Choose the duration for which you’d like to delete the cache files, and click Clear History.

That's it, your browser's cache is now cleared. There are various types of cache on macOS. Clearing cache files also helps you flush DNS on Mac.

5. Stop your Mac startup items

Many apps are set to automatically start as soon as your computer boots up. However, some of these apps don’t have to start at launch and can slow down your Mac. In such cases, the solution is to remove them from your list of login items.

  1. Go to System Preferences and search for Users & Groups using the search bar in the top-right corner.
  2. Click the Login Items tab and search for the apps that shouldn’t be on the list.
  3. Select the apps you want to remove from the list and click the minus (-) icon below the box.
