Empty Cache on Mac – Cache Clearing Guide
What are Caches?
In computing, a cache is a component that stores data so future requests for that data can be served faster; the data stored in a cache might be the result of an earlier computation or the duplicate of data stored elsewhere. A cache hit occurs when the requested data can be found in a cache, while a cache miss occurs when it cannot. Cache hits are served by reading data from the cache, which is faster than recomputing a result or reading from a slower data store; thus, the more requests can be served from the cache, the faster the system performs.
Simply, caches are temporary files that the system and apps use to avoid recreating or re-downloading some information for their operating. It sounds not that bad, but over time caches become bigger and bigger and start slowing your Mac instead of making it work faster. Thus, periodically we have to delete them.
How to delete cache on Mac?
To clear caches remove all files and folders from the following locations:
P.S. If you need to remove the caches of any application, then remove all the content, but not the folder with its name.
Then reboot your Mac. The first boot will be longer than usual – this is normal. In this way, you delete the cache files, most but not all of them.
There are a lot of caches stored in many locations. To find all of them use Clear Disk.
Clear Disk is a utility, that allows you to clear Trash, Caches, Downloads and unused Language Resources.
