Migrate to Mountain Lion

Although all new Macs come with OS X 10.8 Mountain Lion pre-installed, you might have bought a second-hand Mac running the older version of S X such as 10.7 Lion or 10.6 Snow Leopard. Obviously, it’s a very good idea to update, because the latest version includes a host of improvements, bug fixes and features. In terms of hardware, your Mac needs to be the minimum requirements, and you’ll also need an Apple ID to purchase the upgrade from Mac App store.

In theory, all your settings and data will be preserved when you migrate. However, because theory and practice sometimes differ, it’s a good idea to ensure that yo have an up-to-date Time Machine back up on an external drive or removable disk before you start. If your machine has a regular backups set up, then all you need to do is check when the last successful one ran. Click the Time machine status icon in the menu bar and choose One Time machine Preferences. If the latest back up is older than today, run a new one, if your settings get wiped when upgrading, you’ll then be able to restore them from this back up.

Get The Update

You’ll also need to ensure that the most recent OS X updates are all installed so that you can access the app Store, since this is the only way to purchase a Mountain Lion upgrade. Note that the update process will be different depending on whether you’re updating from 10.6 or 10.7.

in 10.6 Snow Leopard, go to the Apple menu, select Software Update and wait while it checks or the new software. Once all relevant updates have been identified, choose Snow details to see which one are available. To save some time, you can opt to install only the Mac OS X Update Combined. Once updates have been downloaded and installed, yo may need yo restart your Mac. Now, once you’ve made sure there’s a recent back up in place, go to the apple menu, then open the App Store to buy and install Mountain Lion. In OS X 10.7 lion, Software Update will launch the App Store for you to upgrade from directly.
