At a glance

• macOS 10.13 or later: CleanMyMac X works on these macOS versions without limitations.

• macOS 10.10–10.12: For these macOS versions, you'll need one of the compatible CleanMyMac X versions released earlier.

• macOS 10.9 or earlier: CleanMyMac X doesn't run on these macOS versions.

We believe that limiting support for older systems gives us more flexibility and resources to develop new features for CleanMyMac.

Another aspect is that Apple doesn't support older macOS versions, so these systems no longer receive security updates. We can't guarantee that CleanMyMac X performs stably and securely with partially supported or unsupported systems.

Finally, some CleanMyMac X features are based on technologies available only in later macOS versions. We can't bring these features to earlier macOS versions because of technical limitations.

Fully-supported systems

To run the latest version of CleanMyMac X and fully enjoy all of its features, you must have any of these macOS editions:

• Tahoe 26
• Sequoia 15
• Sonoma 14
• Ventura 13
• Monterey 12
• Big Sur 11
• Catalina 10.15
• Mojave 10.14
• High Sierra 10.13

Systems with limited support

To use CleanMyMac X with macOS 10.10–10.12, download and install the earlier version of the app that's compatible with your system.

The earlier versions of CleanMyMac X are secure, stable, functional, and regularly receive updates for their malware databases. However, these versions don't get new features or functional updates since their release dates. For example, the Menu isn't included in CleanMyMac X for macOS 10.10–10.11, but is still available for 10.12.

Surely, any subscriptions or licenses remain fully valid. You may renew your subscription after it expires, as usual. And, of course, you may rely on our Support Team for any earlier version of CleanMyMac X.

Unsupported systems

CleanMyMac X won't open on operating systems older than OS X Yosemite 10.10, including these:

• Mavericks 10.9
• Mountain Lion 10.8
• OS X Lion 10.7
• Snow Leopard 10.6
• Leopard 10.5
• Tiger 10.4
• Panther 10.3
