The Ultimate Guide on How to Clear Cache on Mac

By Gina Barrow, Last updated: August 27, 2019

Caches are temporary files and data stored inside the hard drive and used to speed up processes especially on downloading images. This is very helpful when browsing, for example, a Safari browser and a webpage. The images inside the website are stored so when you re-visit the site, the images are already downloaded for faster site opening rather than waiting for few seconds and wait for the images to completely download.

However, these caches build up over time. Although they are temporary files, no one's gonna throw these temporary files for you unless you do it yourself. These files will begin to take up more storage space and instead of its basic function to speed things up, they rather slow your system down.

Thus, we will discover how to clear cache on Mac and boost your device's performance.

Part 2. How to Clear System and App Cache on Mac

System and app caches are hidden files that are usually created by apps stored on your Mac. Meaning, all the temporary files including the media contents are stored inside the system and app files. Some people still argue if clearing both are necessary but then, there's no harm if you try it and if it helps to boost your Mac's performance, then why not?

How to:

Open ~/Library/Caches and remove the contents of the folders with the app name.

Remember: Not all app cache is safe to clear. Some app developers keep significant user info on cache folders so backing up is highly advised!

One of the common examples of system cache is the DNS cache. These are old cache records that interpret internet domain names into IP addresses.

  1. Open Terminal by typing “terminal” into Spotlight
  2. Type this into Terminal: sudo dscacheutil -flushcache;sudo killall -HUP mDNSResponder; say cache flushed
  3. Enter your admin password to execute the command

Note: if you use OS X 10.10.0-10.10.3, use: sudo discoveryutil mdnsflushcache;sudo discoveryutil udnsflushcaches; say flushed

Part 3. How to Clear User Cache on Mac

Next type of cache we will clear is the user cache. This type of cache is the main culprit for the slowing down of your system. It mainly contains all the junk files.

Here are the steps on how to clear user cache on Mac:

  1. First, open Finder and choose the “Go to Folder” from the Go menu
  2. Type: ~/Library/Caches and press enter
  3. Backup Tip: You can also highlight and copy all the files to a different folder in case something happens
  4. Open each folder and clear out contents

Note: Please remove only the contents of these folders, and not the folders themselves

If you want to clear Library Caches, you can do the same steps but replace it with: /Library/Caches (please see the difference)

Part 4. How to Clear Browser Cache on Mac

If you love surfing the internet on your Mac, well you might accumulate a lot of browser caches. Browser caches are also temporary files that store web info especially media files for better and faster access. Over time, they consume at least 15% of the total space of your system so it is necessary to clear them from time to time.

However, each popular browser has different cache setting so you must be familiar with how to navigate:

However, if you are concern about your privacy, you may include clearing the other two. This will then reset your browsing activity and will require you to sign-in to most of the accounts you visited.
  5. Select All Time for the frequency
  6. Click Clear Data
