Clearing an application’s cache does not usually make an app run faster.
For example, if you want to clear the cache for Adobe After Effects, just launch the app and go to Edit > Purge > All Memory & Disk Cache….
Open Finder and go to Go > Go to Folder… Type /Users/yourusername]/Library/Caches (replacing yourusername with your actual username). Click Go to open the folder. Open the folder that contains the cache files you want to delete. Drag individual cache files out of the folder and into the Trash. [2] X Research source
Clearing the system cache will not speed up your Mac. Cache is designed to make it faster for apps and services to load. If you’re trying to make your Mac run faster, try a simple reboot to get rid of unused processes and free up RAM.
Open Finder and go to Go > Go to Folder… Type /Library/Caches. Click Go to open the folder. You’ll find fewer folders in here than you found in your regular application cache. Open the folder that contains the cache files you want to delete. Do not delete an entire cache folder from this location. Drag individual files to the Trash bin.
