What you need is a Mac cleanup software to help you clean up all those junk files and make the most use of every gigabyte. You want to know how to make it faster, and clean up the overloaded junk files to get more storage space. While you will be annoyed if you are a Mac user with a 128GB SSD MacBook pro or MacBook Air, because you will notice that your Mac computer is running slower and slower, or you’re getting the “your disk is almost full” error message after a few months of use. You own a modern Mac computer and are enjoying its awesome performance and great self-maintenance features.
