If not, you should consider upgrading your Mac. Maybe to the new MacBook Air? 

Version & Memory


  • Click the Apple icon at the top left of your screen.
  • Click "About This Mac."
  • Underneath "OS X" is a version number.
  • If this number is 10.6.7 or higher, you’re good to go.
    If you’re running an older version of OS X, you’ll need to look into upgrading your OS X or maybe even consider upgrading your Mac.


  • Below version number, you’ll see “Processor” and “Memory” — If you have 2GB+ memory, great!
    If not, you’ll have to look into upgrading your RAM.

But it All Begins with Hard Drive Space

So, to check how much space you have, again:

  • Click the Apple icon at the top left of your screen.
  • Click “About This Mac.”
  • Click on “More info…”
  • In the new window, select “Storage.”
  • Above the multi-colored bar you will find the phrase, “XX.XX GB free out of XX.XX GB.” 
    Do you have more than 8 GB of free space? Great, you're good to go.

But again, if you need more space, don’t worry, there’s an app for that. Clear out some free space on your Mac with CleanMyMac 3. It’s the fastest, safest way to clean up your Mac hard drive. You’ll have gigabytes of free space in no time!
