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:
- First a bootable copy of my system disk was created with Carbon Copy Cloner.
- Downloaded the Moutain Lion installer from App Store. The price was 149 SEK.
- 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.
- Press continue and wait for a long long time.
