Macs are known for their excellent maintenance: for this very reason, many users when considering MacBook to buy choose this device despite quite a significant cost. There are many debates Mac vs Windows PC but it still remains one of the high-performed systems. However, it is still a challenge to be able to constantly control storage space available on your Mac.

It is not just the matter of keeping it clean: you should understand what you are dealing with and find the source of the problem once it occurs. This can be done either manually or with the help of different automatic programs (you can use free tools built in your Mac or such instruments as MacFly Pro etc.). So how to clean Mac from junk?

12 Shades of Junk

First of all, you should understand what kinds of things are considered as junk and should be deleted. MacOS has been developing over years to avoid absolute junk files and putting it somewhere deep in your system so you do not even know about it. Often junk is either the data which should be regularly erased or info that takes too little space to be noticed. Roughly, there are 12 kinds of junk files to clean up:

  1. App cache (software that keeps application data for retrieving it in the future);
  2. Log files (it stores info about different events, updates, and activities);
  3. Language files (it displays the content of the app in different languages);
  4. Broken login items (link files and entries remaining in the Startup menu);
  5. Duplicates (intentionally or accidentally created copies of the files);
  6. Browser cache (a temporary place for keeping certain web elements);
  7. Development waste (items created by the installation of the app);
  8. Universal binaries (files enable to run on both systems);
  9. Trash files (files in the Trash bin that have not been removed completely);
  10. Old downloads (items saved in mail downloads);
  11. Old backups (automatically created backups after a certain period of time);
  12. Remnant data (files in the system remaining after the app has been uninstalled).

Accumulating such files not only takes up space on your Mac but also slows down the work of the system in general. Therefore, learning how to get rid of junk files on Mac helps Mac to rebuild required data and maximize its efficiency.

Cleaning up

There are three main ways on how to clean Mac of junk:

  1. Manual cleaning
  2. Built-in utilities
  3. Automatic cleaning

You can look through folders on your Mac and delete unnecessary files and unwanted apps manually (however, it will take up hours). You can also use Activity Monitor to check what files take too much space and then delete them (around 40 minutes). And finally, you can use one of the automatic tools (MacFly Pro etc.) which constantly monitor your MacBook Pro and automatically remove all duplicates, cache and other files (a few minutes).


Despite the fact that cleanups can be really helpful, do not become overzealous. In other words, you should use the cleaner only once you have noticed that your device is not working great anymore. You may also avoid cleaning all the temporary files and instead make the focus on the things that are causing the issue. So whether it is making more space on your drive or optimizing system performance, systematic cleaning benefits the work of your Mac!
