Buy once instead of CleanMyMac
4 apps in the directory cover what people use CleanMyMac for. 1 of them is a one-time purchase, and 3 cost nothing at all.
CleanMyMac costs about $40 a year. At that rate DaisyDisk, the cheapest dollar-priced replacement at $9.99, pays for itself in 3 months.
Read the catch on each one before you switch — a one-time price is not automatically the better deal, and we say so where it is not.
