Released on June
The earlier versions of CleanMyMac X are secure, stable, functional, and regularly receive updates for their malware databases. However, these versions do not get new features or functional updates since their release dates. For example, the new Menu is not included into 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 Customer Support for any earlier version of CleanMyMac X.
Unsupported systems: 10.9 and older
CleanMyMac X will not open on operating systems older than OS X 10.10 Yosemite, 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)
❌ Jaguar (10.2)
❌ Puma (10.1)
❌ Cheetah (10.0)
Does CleanMyMac X work on macOS 14 Sonoma?
Yes, but you need to install the beta version of CleanMyMac X.
Remember that macOS Sonoma is also a beta version. Apple says betas “may contain errors or inaccuracies and may not function as well as commercially released software.” The same is true for any apps you install on a beta operating system.
Please don’t get upset if CleanMyMac X has issues with macOS 14 Sonoma. We’d appreciate it if you let us know about possible problems. This information will help us fix the issues and make CleanMyMac X more stable and reliable. Thank you!
Why is CleanMyMac ending full support for older systems?
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 does not support older OS versions, so these systems no longer receive security updates. We cannot guarantee that CleanMyMac X performs stably and securely on unsupported systems.
Finally, some CleanMyMac X features are based on the technologies available in later macOS versions only. We can’t add these features on earlier systems because of technical limitations.
