To be honest, I ran the trial version of MacKeeper and I did like it. But from my research, I found out that it is not the most "kosher" program to keep your Mac clean. Quote on Quote: "MacKeeper has been described by various sources as highly invasive malware" So, I came across 'CleanMyMac 2'. Ran it, liked it, but..... my machine (2011 MBP 2.3Ghz i5 16GB ram) started acting up right afterwards for a brief period of time. Nothing major, nothing which couldn't be fixed with a restart, everything back to normal now. 1. What program do you use, to keep your Mac clean? 2. Anyone else having issues with 'CleanMyMac 2' 3. Any other recommendations on similar software?
