Anyone here has used this program? Meron daw disk optimizing, parang PC, pero many people say na Macs don't need optimizing. Which is which ba? I used to optimize and defragment my PCs every month, pero I never needed sa Mac. If its not important, bakit meron feature na to sa Techtool. Very confusing. Anyway, just want to know if anyone had experience with this program, and if its a good buy. I looked at reviews sa internet, pero magulo - some like it, some dont, pero di ko naman kilala tong mga to. He he.
