Supported macOS versions

How do I know which macOS version is on my Mac?

Click the Apple menu (upper-left corner of your screen) and choose About This Mac. The macOS name and its version are in the very center of the window.

CleanMyMac X fully supports macOS 10.12 and newer

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

  • Ventura (13)
  • Monterey (12.4)
  • Big Sur (11.6)
  • Catalina (10.15)
  • Mojave (10.14)
  • High Sierra (10.13)
  • Sierra (10.12)

Operating systems with limited support: 10.10 and 10.11

On OS X El Capitan (10.11) and Yosemite (10.10), you can only use CleanMyMac X 4.10.7 (download it here).

This version is fully functional and regularly receives updates for its malware database. However, CleanMyMac X 4.10.07 has only the features released before June 02, 2022; newer features are not available. 

Surely, subscriptions or licenses remain fully valid. You may renew your subscription after it expires, as usual.

Why is CleanMyMac ending full support for OS X 10.10 and 10.11? 

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

We also explain our motivation in details in this blog article. Here are the key highlights from it:

- Apple doesn’t support older OS X versions, so they no longer receive security updates.
- We cannot guarantee stable performance of the application on unsupported systems.
- Technical restrictions don’t allow us to add new features that are available for more recent versions of macOS.

Non-supported operating systems: 10.9 and older

CleanMyMac X will not 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)
  • Jaguar (10.2)
  • Puma (10.1)
  • Cheetah (10.0)

Find out which CleanMyMac X version is on your Mac

  1. Open CleanMyMac X.
  2. In the menu bar (upper-left corner of your screen), choose CleanMyMac X > About CleanMyMac. The version is in the lower-left part of the window.
