I am thinking about buying MacKeeper (since it's now 38 dollars on their website). Is it reliable? I tried using it for the fully functional trial to recover lost data (not that much important stuff, but I did want to see what I could get back). I tried to hit recover on the supposedly free functional 15 day trial, but they make you pay to recover. Is it worth the 38 dollars for long run? I use diskdrill from the app store, but it only recovers external drives (and it's not even that great). Has anybody tried using a fully functional version of MacKeeper? If so, what do you think about it?
