It is not easy to pick a fitting Mac optimization tool since the only thing that is certain for both PCs and Macs is that a little tampering with the settings is enough to render your OS virtually useless. This is why it is practically mandatory to first try out your this software in some way or another.
Thankfully MacPaw, the company behind the pair of ‘CleanMy…’ tools, figured out how to please uncertain customers and those who are happy to have limited access without paying. Opting for downloading the free version of CleanMyMac won’t limit the software’s functions, though you can’t exceed 500MB of junk data removal. However, if you want to take the full program for a spin, you can pay the purchase price and get a full refund within 30 days via the money back guarantee should you not be satisfied with what you get.
