After waiting for Leopard to arrive I finally got my hands on it and went ahead with the installation. When you install your latest OS X you have a few choices:
In the past I’ve usually done a full HD backup, I then format the drive, and do a clean install of the new OS – using the upgrade as an excuse to clean house and get rid of all the crap that accumulates over time. But for some reason when I went through the process this time, the only option available to me was an “Upgrade”, which entails updating the OS as well as all applications and settings ( I later learned that perhaps having my external USB hard drive connected was the cause of that single option. )
So I rolled the dice and after doing the “upgrade” i noticed lots of sluggishness and beach balls a plenty !
So over the holidays I finally decided to do a full cloning of my hard drive using carbon clone ( which was simple and worked well ), and then proceeded with a clean install of Leopard aptly named “erase and install”.
Things are now snappy and that clean fresh OS feeling is quite minty ! You can also use the built in migration tools to transfer settings or just use the clone to copy over the “home” directory.
