All operating systems use cached files for better performance. Caches can be described as small areas where computer stores data that probably will be used again. For example, they save data from the websites you open, so they load faster when you revisit those domains.

Your computer stores system, browser, and app cache files on your hard drive in several locations. All this data is helpful, but with time it can pile up and take up too much space or affect the performance of your machine. That is why learning how to clear the cache on Mac is important for computer maintenance.

Is it Safe to Clear Cache on Mac?

Even though it is usually safe to clear the cache, you should still be careful when deleting data on your computer. Be attentive and select only the file you intend to erase for removal.

You shouldn’t face any issues when removing the browser cache and system files in folders /Library/Caches/ and ~/Library/Caches/. But take a closer look when clearing the app cache of software you constantly use since the developers sometimes use cache folders for important files.

You can also create a backup or a copy of the folders before the removal so you can revert the changes in case anything goes wrong.

How to Clear System Cache on Mac

System cache files help maintain your Mac’s excellent performance, so there is rarely a need to delete them. But with time, it can pile up and clutter your disk space too much.

How to Clear Application Cache on Mac

Every app on your computer saves its individual cache files. Similar to system caches, there is no need to clear them regularly. But it might be a good idea if it takes too much space or the application lags or works incorrectly.

1. Open finder and click on Go > Go to Folder
2. Type /Users/[YourUserName]/Library/Caches in the window that appears

In this folder, look for the files with the app name for which you want to clear the cache. You can then simply drag those items to Trash and empty it to delete the files completely.
