This wikiHow teaches you how to clear the cache of temporary system files that your Mac stores as you use it, as well as how to clear the Safari browser's cache of temporary Internet files. Keep in mind that clearing the system cache can cause your Mac to freeze or crash unexpectedly; this is a normal response to clearing the cache.

Clearing the System Cache

  1. Close as many open programs as possible. Open programs use files from the "Cache" folder, so you won't be able to remove as many cached files as you like if you have multiple programs open.
  2. Go to your Mac's Finder. Do this by clicking on your Desktop image or on the blue smiley-face icon on the far left in your Dock.
  3. Click Go. It's in the menu bar at the top of the screen. A drop-down menu will appear.
  4. Click Go to Folder…. You'll find this option near the bottom of the Go drop-down menu. Doing so opens a text box.
  5. Enter the "Library" folder path. Type ~/Library/ into the text box.
  6. Click Go. It's a blue button in the bottom-right corner of the text box. This will open the Library folder, in which you should find a folder named "Caches".
  7. Double-click the "Caches" folder. This folder should be near the top of the Finder window, but scroll down to find it if it isn't there.
  8. Select the "Caches" folder's contents. Click one item or folder in the "Caches" folder, then press ⌘ Command+A. Doing so selects everything in the "Caches" folder.
  9. Delete the "Caches" folder's contents. Click the File menu item at the top of the screen, then click Move Items to Trash in the drop-down menu. The "Caches" folder's contents will be moved to the Trash.
    • If you receive an error telling you that one or more of the files can't be deleted, they're being used by a program that's currently open. Skip deleting these files for now, then try deleting them later when the programs in question aren't open.
  10. Click Finder. It's a menu item in the top-left corner of the screen. A drop-down menu will appear.
  11. Click Empty Trash…. This option is in the Finder drop-down menu.
  12. Click OK when prompted. Doing so will empty the trash, thus completely clearing the cache files from your Mac.

Clearing the Safari Cache

  1. Open Safari. The Safari app icon resembles a blue compass, and can usually be found in your Mac's Dock at the bottom of the screen.
  2. Click Safari. It's a menu item in the top-left corner of the screen. A drop-down menu will appear.
    • If you see a Develop menu item in the bar at the top of the screen, click it instead, then skip ahead to the "Click Empty Caches" step.
  3. Click Preferences…. It's near the top of the Safari drop-down menu. A new window will open.
  4. Click the Advanced tab. You'll find it on the far right side of the Preferences window.
  5. Check the "Show Develop menu in menu bar" box. It's at the bottom of the Preferences window. This adds the Develop tab to the menu bar for Safari.
  6. Click Develop. It's an option in the menu bar at the top of the screen. A drop-down menu will appear.
  7. Click Empty Caches. You'll see it in the Develop drop-down menu. Doing so will automatically clear your Mac's Safari cache.
    • You won't see a pop-up window or a confirmation notice when the cache is cleared.

Tips

  • If you use a different browser than Safari, you can clear your browser's cache from within the browser's settings.
  • It's normally a good idea to restart your computer once the cache has been cleared since clearing the cache can cause your Mac to run into errors or glitches until you restart it.

Warnings

  • Clearing the system cache may cause your Mac to crash. While your Mac should restart and begin working again without any problems, make sure that your work is saved and that you've exited any open programs before clearing the system cache.
