Put your Mac on a diet with CleanMyMac

Put your Mac on a diet with CleanMyMac.  I was approached by this company a few months ago to write an article on this program.  I agreed to try it out first, and I ran everything that it could do.  I then had problems that required the reinstallation of Snow Leopard.  I do not trust this app.  In contrast, I have never had a problem with Tinkertool, Onyx, or YASU.
