With CleanMyMac X, data is removed when it is no longer needed instead of it hanging around on your system for years. Monitoring the applications on your Mac is important because there is a tendency for modern apps to leave files scattered everywhere on your computer, and much of it can hold personal data. CleanMyMac X does hard drive management, erases web browsing history and website cookies, cleans up unused apps, and junk files for quick and permanent deletion, making taking care of your Mac system easy.
