"Piece of junk not worth $80 or $50 for upgrade."1.0 starson by teabing
Pros: Does what it says it will do but doesn't tell you that it will also mess up your computers OS. Version 7 works just fine with Mountain Lion.
Cons: If you use this product and also use Micromat's TechTool Pro 6.0.5 you will find that Volume Rebuild will always give you a red number which usually means a change that you don't want to make. It will also not allow for complete Volume Optimization.
Summary: Buy this and suffer though a messed up OS. Would give it no stars if possible. Wasted a good 8 hours of time dealing with Micromat and Apple just to find that Parallels 8 is a piece of junk and was the problem. Have no idea how many files it damaged and each one I find Parallels is going to hear about it.
