Apple is probably releasing the next OS X version tomorrow. Why I wont be upgrading instantly.
Upgrading OS X to its latest version will be easier than ever. Apple decided to even dump the classic retail model and go for a ‘online-only’ one click upgrade path. You can buy the €23,99 upgrade from Apple’s online Mac App Store and it will download and self install. This makes the step from ‘Snow Leopard’ to ‘Lion‘ an easy one, but beware, upgrading comes with some dangers. I rely on Adobe’s CS5 software for a lot of work and a previous early upgrade gave me some serious problems.
Even thou a new Operating System like Lion has been thru intensive beta testing it is still a young and immature OS, this makes it wise to first wait for confirmation that the software you rely on for your daily bread functions without hiccups and then consider upgrading. Usually this process takes about three months and you can take track of this best by googling on the subject once in a while.
If you really can’t wait for Lion I recommend you install it on a separate partition as a Clean Install so you can always go back to your old system. Once you’re ready, copy all of your files and Voila, you’re up to date.
Update: The guys at Mashable made a lovely tutorial on clean-installing lion.
Update 2: Most of Adobe CS5 seems to work lovely on Lion, i’ve tried Fireworks and Photoshop myself and I came across no hiccups.
