SimBooster is an all-in-one package that includes a variety of system tools to help you clean and protect your Mac. For slow Macs, SimBooster can release RAM to increase the processing speed. It can also help users protect their personal data from malicious cookies. SimBooster doesn't just look for system junk - it also finds large files you've forgotten about or haven't opened in a while such as movies, .dmg files, and unpacked archives. SimBooster can identify and remove such files to return you more space to use.
