I'd stay away
I have been using Mac TuneUp for some basic things and liked it OK.
However, when I decided to use the clean-up cache feature, Mac TuneUp deleted ALL my software, system settings, user folders, and some firmware. 😡
It wound up being worse than a virus.
I'd pass on the software. It really put me in a pickle. Apparently, it has done the same to others, but Mac TuneUp still sells it without a fix. 😕
