4. Clean Junk Files

Over time, as you use your Mac, junk files are bound to accumulate since your Mac preserves some history of the usage of apps and their functionality. It is also advised that you get rid of junk files from time to time as these files may cause issues such as the error 102 on your Mac. However, it might not be possible for you to clean the junk out of your Mac manually. This is where you can take the help of a Mac cleaner. For instance, CleanMyMac X is one of the best Mac cleaning apps. With the help of this tool, you can get rid of System Junk in the form of user and system cache and log files and broken login items.
