I own a late-2010 MacBook Air (1.4 GHz Core 2 Duo, 2GB RAM), and I'm wondering if should update my OS from Snow Leopard to Mountain Lion. CON: The obvious argument against updating is that I have only 2GB RAM, and this worries me. I don't find this to be very problematic in Snow Leopard, but. Mac Pro introduced in early 2008 or later Xserve models introduced in early 2009. To find your Mac model, memory, storage space, and macOS version, choose About This Mac from the Apple menu. If your Mac isn't compatible with OS X El Capitan, the installer will let you know.

You can find out what OS X version you are on by clicking on the Apple icon, then select the 'About This Mac' menu item. The number under the Apple logo is the version you are on. 10.5.x is Leopard, 10.6.x is Snow Leopard and 10.7.x is Lion.
If you are on Leopard:
You can't go from Leopard to Mountain Lion directly. You first need to upgrade to Snow Leopard. Read my post 'How to upgrade from Leopard (10.5) to Snow Leopard (10.6)' and then continue reading the 'If you are on Snow Leopard' section below.
If you are on Snow Leopard:
You can go from Snow Leopard to Mountain Lion directly, but first make sure you machine supports it. Give Apple a call, 1-800-MY-APPLE (1-800-692-7753), and they'll tell you whether or not you can upgrade to Mountain Lion.
If you can upgrade to Mountain Lion then read my post 'Where is the Mac App Store on Leopard (10.5) or Snow Leopard (10.6)' to make sure you have the version of Snow Leopard that has the App Store. Once you have the App Store then continue down to the 'Upgrade to Mountain Lion from the App Store' section below.
If you can't upgrade to Mountain Lion then you should consider upgrading to Lion. Read my post 'How to upgrade to Lion (10.7) from Leopard (10.5) or Snow Leopard (10.6)'.
If you are on Lion:
If you are already on Lion then you can upgrade to Mountain Lion through the App Store – just call Apple first to make sure you machine is compatible with Mountain Lion and continue reading below.
