✅ macOS 10.13 High Sierra and newer: CleanMyMac X works on these OS versions without
limitations
🟡 macOS 10.10-10.12: for these systems, you'll need one of the compatible CleanMyMac X versions
released earlier
❌ macOS 10.9 and older: CleanMyMac X does not run on these OS versions
Also learn why we limit support for older operating systems, and how to find out
which macOS and CleanMyMac X versions you're
using.
Fully-supported systems: macOS 10.13 and newer
To run the latest version of CleanMyMac X and fully enjoy all of its features, you must have any of these macOS editions:
- Ventura (13)
- Monterey (12)
- Big Sur (11)
- Catalina (10.15)
- Mojave (10.14)
- High Sierra (10.13)
Systems with limited support: macOS 10.10-10.12
To use CleanMyMac X on macOS 10.10-10.12, install the earlier version of the app that is compatible with your system.
| macOS version | Compatible CleanMyMac X version (click to download) |
|---|---|
| 10.12 Sierra | 4.12.3 Released on December 22, 2022 |
| 10.11 Capitan, 10.10 Yosemite |
4.10.7 Released on June 02, 2022 |
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)
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.
