As you have probably noticed, CleanMyMac 2 has taken a back seat on our website after the release of CleanMyMac 3. That's because this new version of CleanMyMac is much better in revealing disk space and keeping your Mac healthy. We've changed its design, improved cleanup features, and added useful maintenance tasks. And, since we want the Mac community to get the best products and services, only CleanMyMac 3 is now available for download.
However, if you'd like to go on with CleanMyMac 2, it's also possible. Here's your download link for CleanMyMac 2, but please note that it supports macOS 10.7-10.12 only (CleanMyMac 2 won't work on High Sierra).
