Upgrade of Lion to Mountain Lion

I finally decided to upgrade my Mac Mini from OS X 10.7 Lion to 10.8.2 Mountain Lion. I waited a service release and read the reviews. This is my first major update of a OS X system. Before this I only had minor upgrades.

It was easy to upgrade and it went well.

These where the few simple steps:

  1. First a bootable copy of my system disk was created with Carbon Copy Cloner.
  2. Downloaded the Moutain Lion installer from App Store. The price was 149 SEK.
  3. When the app with a picture of a big cat appeared, I made a copy of the 4.4 GB large installer file. Otherwise it would have been deleted after the installation was completed.
  4. Press continue and wait for a long long time.
  5. Done!
