Mac is really helpful but cleaning it regularly is one of the annoying thing ever. Not just that its really make my mac slow but i am not sure if i can ever use without cleaning it , so i was looking for an option and when i did , i got this one. After looking at few basic things and reviews, i thought of trying it. i bought the software and run in my mac. Well i must say its really much better than any other option i have tried. Not just my mac is working smoother than ever but also cleaning trash , history etc is much easier than ever.
