Before we start


Macs, like all computers, use caches for maintenance and performance purposes—from browsers to individual apps. But you need to clear cache from time to time to let your machine browse faster and reduce the load on websites.


To prevent your Mac from being overloaded and overheated, use dedicated cleaning software. MacKeeper’s Safe Cleanup tool is good for getting rid of junk files and clearing cache on Mac—both to optimize your laptop.


To use MacKeeper’s Safe Cleanup tool:

  1. Download MacKeeper on your MacBook Pro, MacBook Air, or iMac and select Safe Cleanup in the sidebar
  2. Click the Start Scan button and wait a few minutes while the tool checks your Mac
  3. When the scan is done, click Clean Junk Files and let MacKeeper work its magic.



What are caches on Mac?

In the computing world, cache (pronounced “cash”) is a temporary data storage location or a memory bank that fast tracks the retrieval of data. Namely, it allows your browser to load websites you've previously visited faster.


It achieves this by storing data in a hardware device that can be accessed fast (like random access memory). As a result, the cache eliminates the need to tap into the data’s core storage location, which speeds up the response time. That’s why clearing your Mac’s cache can slow down response times, but this measure is essential to help your computer perform more efficiently.


There are three main types of caches on your Mac:

Cache type


System cache              This is the glue between the main memory and a processor. System cache is stored on your Mac’s system to help your device execute instructions quickly so that you can enjoy a fast and efficient experience. Otherwise, it would take a while to carry out tasks on your Mac
Browser cache                                  Every browser you use on your Mac manages cache files that store essential elements. These elements include JavaScript, HTML, cookies, CSS, and images that help the browser display websites. It’s what keeps your online shopping carts intact.
User cache                         User cache includes app cache. Every app on your Mac has its own cache. Similar to browsers, these cache files improve the performance of apps by loading images, videos, and search history fast

Do you need to clear cache on your Mac?

Caches are generally good for your Mac, but, in our experience, they can cause issues too. In such cases, you may need to delete your Mac’s cache. Below are the reasons why you should clear cache:

  • If they grow too large, they can affect your Mac’s speed, particularly on an older machine
  • They can also end up hogging disk space that could be put to better use
  • Cached data may become corrupted, causing your Mac to behave unpredictably
  • Cached data may contain private information that you don’t want other people to see.

If any of these things happen, then it can be a good idea to clear caches on your Mac.

What happens if I delete all cache files on Mac?

If cache files are so important for your Mac’s performance, you may wonder if anything bad would happen if you delete them. It’s good to be careful about deleting stuff from your Mac, but it’s generally safe to remove cached data from your MacBook. You shouldn’t run into any major issues if you delete cached files from system-level and user-level folders. Deleting cache isn’t permanent either.


However, our advice is to be cautious when deleting cached files in apps, as some developers store important files in the cache folders. Be wary of deleting cache files from apps you’re actively using, as you run the risk of deleting your work or progress.


If you're in any doubt, use a cleaning tool like MacKeeper. It checks which files are safe to delete, so you don't accidentally remove essential files.


If you do proceed, take note of the results of deleting cache files on a Mac device:

  • Some site settings will be reset, so you may have to sign in to your online accounts again
  • Websites will load much slower than you’re used to because their elements—including images, text, and video—will have to load from scratch again
  • You’ll free up more space on your MacBook.
