How to Check the Cache on a Mac Computer
Checking the cache, a storage area containing frequently accessed data, on a Mac computer is simple. You can locate and check the cache of a given Mac application, including web browsers, via its corresponding menu options, or locate a global folder that holds an organized list of subfolders containing the cache for all applications. System cache and user cache are found in different locations for Macs. In both, you may view the cache's contents and size to decide whether you wish to clear this data.
