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 an enormous 2.05 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 if 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

Make sure that once you have finished clearing out these caches for additional hard drive space, you empty 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.

4 main types of the cache within the Library folder

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
The Preferences 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.

Containers
Containers folder is an exchange buffer that apps use to communicate with one another. This is often referred to as “sandboxing.” The Containers folder is automatically emptied after you restart your Mac.

Next up, we’re looking at your system cache files. These hidden cache files are mainly created by the apps that run on your Mac.

What is app cache? In short, it’s any media downloaded by the apps you use to work faster and not load it every time you open the app. Do you need it? It’s debatable, but the app cache takes up disk space and can be cleaned.

You can delete the app cache on Mac in the same way as the user cache by going to ~/Library/Caches and removing the insides of the folders with the app name.

Proceed with caution! Not all app cache can be safely cleared. Some app developers keep important user info on cache folders. Backing up a folder before you delete is always a good idea. If everything works fine, then you can delete the backup later.

To be on the safe side, use CleanMyMac; it works with a Safety Database, and knows how to clear the app cache safely. As if that wasn’t enough, it will also remove more junk than manual methods.
