Apple announced recently that their new Mac OS X version, Mountain Lion, will be released next month for $19.00. At this price point it’s expected that many users will opt to upgrade and stay current with the latest operating system and its features. Also, if you buy a new Mac now and it ships with Lion you will get a free upgrade offer for Mountain Lion. If you are upgrading OS X through the App Store it’s imperative that you make a bootable back up for Lion or Snow Leopard beforehand.
First things first, does your Mac support a Mountain Lion upgrade ? Make sure your Mac can run Mountain Lion.
Your Mac must be one of the following models: ▪ iMac (Mid 2007 or newer) ▪ MacBook (Late 2008 Aluminum, or Early 2009 or newer) ▪ MacBook Pro (Mid/Late 2007 or newer) ▪ MacBook Air (Late 2008 or newer) ▪ Mac mini (Early 2009 or newer) ▪ Mac Pro (Early 2008 or newer)
I also suggest cloning your 10.6 or 10.7 volume or create a bootable backup to another drive before upgrading. Typically the upgrades go fine, however we did see a good number of users buying Data Rescue 3 to recover files after Lion failed to upgrade properly. We suggest running a dual boot Mac with your current and new operating system at the same time. This allows you take your time while you upgrade and have the luxury of your old OS intact. This is a safe and convenient way to approach an operating system upgrade.
Make a list of your important applications that you must have support for. Check them for 10.8 support , just because Apple is launching a new Mac OSX doesn’t mean every other software developer will have support for it. We have seen this with Snow Leopard and Lion. If you use professional software it is even more important to check before upgrading. Many mainstream applications will be behind the Mac OS X upgrade curve.This is why I highly recommend a dual boot drive so you can experience the new Mac OS X but not have to worry if all your applications can’t run on it yet.
