Manually Clearing Cache Files

• System Cache: Open Finder and select “Go to Folder” in the Go menu. Type in /Library/Caches and press enter. You’ll see a bunch of folders, each corresponding to an app on your Mac. You can go into each folder and delete the files inside, but do not delete the folders themselves.

  

• User Cache: This is similar to the system cache but is specific to your user profile. You can access it by going to ~/Library/Caches (the tilde represents your user directory).
• Browser Cache: Each web browser will have its own method of clearing cache. For example, in Safari, you can clear the cache by choosing “Clear History” from the History menu, then selecting “all history“.

  

Using Third-Party Tools

There are several third-party tools that can simplify the process of clearing cache files. Here are a few examples:

• CleanMyMac X: This is a popular Mac cleaning tool that can help you remove system junk, including cache files, with just a few clicks. It also offers other features like malware removal and optimization. Learn more on removing leftover apps with CleanMyMac X.
