How to Update Your Mac OS for CleanMyMac 3

CleanMyMac 3 works on 10.8 and later. There are five OSes that can upgrade to CleanMyMac 3: Mountain Lion (OS X 10.8), Mavericks (OS X 10.9), Yosemite (10.10), El Capitan (10.11), and macOS Sierra (10.12). Sierra is newer, has more features, and is free and we highly suggest update your Mac to macOS 10.12.

Requirements for Upgrading to Sierra:

You’ll need 2 GB of RAM (preferably 4 GB), 8 GB of free disk space on drive, and one of the following Macs:

• MacBook
  Late 2009 or newer
• MacBook Air
  Late 2010 or newer
• MacBook Pro
  Mid 2010 or newer
• iMac
  Late 2009 or newer
• Mac Pro
  Mid 2010 or newer
• Mac mini
  Mid 2010 or newer

To check your how much memory you have, follow these steps:

1. Click the Apple icon at the top left of your screen.
2. Select “About This Mac” and then click on “More info…”
3. Next to “Memory,” you’ll see the amount of RAM (memory) you have.
   If you’ve got more than 2 GB of memory, great. If not, consider upgrading your RAM in order to upgrade to El Capitan.

To see how much disk space you have:

1. Click the Apple icon at the top left of your screen.
2. Select “About This Mac.”
3. Click on “More info…” and then “Storage.”
4. Next to the name of your hard drive, you’ll see the phrase “X.XX free out of XXX.XX.”
   If you have more than 8 GB free, cool, you’re good to go.
