Like a desk, an apartment, or even the back of your car, your Mac requires a bit of tidying now and then. You download stuff, install programs, back things up and before you know it your hard drive is cluttered with files that you don’t even realize are there. Clean My Mac 2 scans your system and helps you make room with the click of one button. And today, you can get two licenses for the price of one, allowing you to keep two Macs nice and clean. It’s $29.99.
