Before the clean-up, let's see what's taking up space of your Mac's hard drive so that you will know what to clean to get a faster Mac. Here is how you can check your hard drive storage on Mac:
Click the Apple icon at the top-left corner of your screen.
Choose "About This Mac."
You’ll see that there are six kinds of data that are eating up your storage: photos, movies, apps, audios, backups and other. You probably have no doubt about the first five kinds of data but get confused about what this "Other" storage category is. And sometimes it is the "Other" data that takes up most of the space on your hard drive.
In fact, this mysterious "Other" category includes all data that can't be identified as photos, movies, apps, audios, backups. They could be:
Documents such as PDF, doc, PSD;
Archives and disk images, including zips, dmg, iso, etc;
Various types of personal and user data;
System and applications files, such as user library items, user caches and system caches;
Fonts, app accessories, application plugins, and app extensions;
Now that we have know what's taking up the space of the Mac hard drive, we can search for the unwanted files and delete them to clean up space. However, this is much more troublesome than it sounds. It means that we have to go through folder by folder to find the unwanted files. Moreover, for system/application/users files in "Other" catagory, we don't even know the exact locations of these files.
That's why developers create different Mac cleaners to make cleaning easier and more effective for Mac users. Dr. Cleaner, the program that will be introduced below, is top-ranked among its kind.
Dr. Cleaner is a free cleaner for Mac that you can download from iTunes Store.
You can use the program to:
