How to empty user cache on Mac?
Potential space reclaimed from junk - Up to 70%
As you can see, a single user cache folder on my computer takes up enormous 1.6 GB of space. And that’s just one folder out of hundreds. That means a good cleaning could free up gigabytes of free space and speed up your Mac in the process.
To clear your user cache, do the following:
- Open a Finder window and select “Go to Folder” in the Go menu.
- Type in ~/Library/Caches and hit enter to proceed to this folder.
- Optional step: You can highlight and copy everything to a different folder just in case something goes wrong.
- Go into each of the folders and clean out everything.
Note: We recommend that you remove the insides of these folders, but not the folders themselves.
Now, repeat the same steps above, but substitute…
~/Library/Caches with… /Library/Caches
~/Library/Caches with… /Library/Caches
Make sure that once you have finished clearing out these caches for additional hard drive space, you empty out your Trash. To do this, Control-click on the Trash icon in the dock and select “Empty Trash.” Restart your Mac afterward so your Mac can begin to create new, fresh cache files.

Caches
Temporary data created by apps and websites. Your apps keep generating cache files for as long as they are active. Relying on such pre-loaded content reduces memory load and speeds up data exchange.
Preferences
Prererences folder is where you’ll find customized settings for your apps. Sometimes, there is a need to reset an app and delete its corrupted Preferences file. Preference files always end with .plist — so they are easy to spot and delete.
App support
App support folder contains large pieces of app data, like game saves. App support files may remain on your Mac long after you’ve deleted the app itself. That’s why “cleaners” for system junk were invented.

Potential space reclaimed from junk - Up to 15%
We all love to surf the web but every site we visit adds to the growing browser cache. Clearing your browser cache doesn’t just free up space, it will can also clear your browsing history to secure your privacy.

Also, resetting your browser cache will potentially help to get rid of 404, 502, and other errors caused by corrupted cache.
Each browser has its own cache location, so the process of clearing is different in each case. For instance, Chrome cache location is in Settings, Safari stores its cache in Privacy, and Firefox cache location is History tab.
Here’s a quick introduction into how to delete browser cache on Mac.
