Feel free to poke around — we’ve got answers for common questions about activation, license, compatibility, upgrades, and more.
Generally, your activation number can only be used on one Mac at a time unless you have a license for multiple Macs. To upgrade your single license version to multiple Mac license, please contact Customer Support.
To transfer your license to a different Mac, you need to deactivate CleanMyMac first:
If you've already removed the app or do not have access to the computer anymore, please refer to our License Retrieval system. Detailed instructions are here.
After CleanMyMac has been deactivated, it can be installed and activated on the Mac of your choice with your original activation number.
If you encounter problems while deactivating and reactivating your license, please contact our Customer Support for assistance.
If you lost your activation number and can’t find it in your inbox, take advantage of our License Retrieval feature.
If that doesn’t help, please contact us via this form.

The Photo Junk module scans your Photos library (or iPhoto, if you haven’t upgraded to Photos yet) to remove useless junk only. In Photos, it’s iCloud local copies, Faces cache, and other app-related cache. In iPhoto, it’s invisible original versions of files that were automatically or manually modified. For instance, if you imported a photo from your camera and then rotated and cropped it, iPhoto will keep an unrotated, uncropped copy of it as a backup. You can remove these unnecessary files to decrease the size of your photo library significantly.
The Menu gives you quick access to useful features of CleanMyMac 3 and lets you monitor your Mac’s health. For example, you can launch CleanMyMac 3, free up RAM, get hardware alerts, and empty Trash.
