How to Clean Junk Files on Mac Directly

As there are two ways of getting rid of junk files on Mac, you can do it yourself manually in the old fashioned way. You can remove all junk files one by one to free up your Mac. But compared with using Mac Cleaner, it is more complicated and takes more time to clear junk files.

1. Clean up System Junks

One of the most effective ways of freeing up your Mac and creating more space from the hard drive is cleaning up the junk your macOS has accumulated. System Junks includes temporary and unnecessary files left behind by the activity log, cache, language database, leftovers, broken app data, document junk, universal binaries, development junk, Xcode junk, and old updates that you probably didn’t know had left behind some seemingly harmless pieces of stuff that would soon become a pain in your Mac system.

How do you get rid of all these junks? You will have to open the folders one after the other to empty their contents; don’t delete the folders themselves. To be on the safe side, you can first copy the folder to another destination, either another folder or perhaps an external drive if you have one before you delete them. This is because you don’t want to delete files your system actually needs. However, after deleting them, once you see that it doesn’t affect it negatively, you can go on and permanently delete it.

Mac saves a lot of information in files with or without your involvement. These files are called Caches. Another way to relieve your Mac of the junk is to clean up the cache on Mac. It stores all the information so that you don’t have to go back to the original source to get it again. This is both helpful and unhelpful at the same time. It makes your work easier and faster, but all those cache files stored take up too much space on your Mac. So, for your system’s sake, you might want to clean up those files. Open each of the folders, and delete them.

2. Clean up Unused Language Files

Most apps on Mac come with a language database that gives you language choices from which you can choose any language you prefer. This would be perfect but this database eats up a lot of space on your Mac’s storage. Since you have already chosen your preferred language, why not just remove the remaining language data and free up space on your Mac. Simply go to where the applications are and find the app with the language database you want to delete and delete them.

3. Uninstall Unwanted Apps

The more the apps you install on Mac, the more its storage space reduces. And the storage gets bigger if you use those apps more. Now, I know some of those apps are nice and appealing but, for your Mac’s health, you might want to only install apps you need. This is because those apps take a large percentage of the space hence increasing the risk of your system getting low on storage which slows down its performance. To free up space from Mac, you would have to delete these apps on Mac completely. If you only drag them to the Trash bin, it won’t help at all because dragging them to the trash bin won’t remove all the files and caches they have generated.

4. Delete Mail Attachments

Mail attachments, when they are too many, make your system overloaded hence putting it at risk. Delete these attachments you don’t need anymore and free up space on your Mac. Besides, these attachments are still in your mailbox so you can always download them again anytime you need them.

5. Remove iTunes Junk

iTunes junk includes the backups of iPhone, broken downloads, iOS update files and caches that are useless to your Mac and they can be deleted to free up space. Deleting them won’t cause any problem.

6. Remove Browser Cache and Extensions

You may not know this but when you browse, your browser stores cache that takes up space. Your browsing history, download history, etc. swallow up space your system needs for better things. The best thing is to clear out your browsing history, delete the caches and remove the extensions once you confirm you don’t need them anymore.

7. Empty Trash Bins

All the files, apps, folders, and caches you delete end up in the Trash bin of your system where they still take up precious space. So, to really create more storage space, you need to empty your Trash bins. Since they are useless, this shouldn’t be a problem. If you keep them there, you still put your system at risk of crashing due to low storage. To do this, just click and hold on the Trash bin icon; select “Empty Trash” from a popup that appears and you’re good to go.

Conclusion

Low storage on Mac is injurious to its health so it needs to be cleaned. However, you should know that deleting junk files is not a one-time thing. You should do the cleaning and keep your Mac smoothy all the time. In this case, Mac Cleaner is the best tool that you can clean up useless files in an easy way every day. Keeping your Mac good and new is a simple task to Mac Cleaner.
