So you’ve checked out the good stuff and decided to take the plunge to Snow Leopard. Upgrading is mind-numbingly easy, but in case you wouldn’t mind a little hand-holding, here’s our quick and simple UltraNewb guide to upgrading from Leopard to Snow Leopard.
Prep Your Mac
One thing to note: You’ll need at least 5GB of free space to upgrade using the basic Leopard-to-Snow-Leopard upgrade path. If you don’t have enough free space (my laptop didn’t), try an application like GrandPerspective to identify large files you don’t need and free up the necessary space.
Install Snow Leopard
This process is exceedingly simple, but as I said above, sometimes it’s nice to watch the canary in the coal mine so you know what to expect. So, here goes:
1. Insert the Snow Leopard DVD: Just insert your Snow Leopard DVD, open it up, and double-click Install Mac OS X.
At this point, you’re pretty much done. (We told you it was easy.) Grab a cold drink, put on some music, and wait. The installation will start as soon as you enter your password. On my computer, the install process went on for about 15 minutes, then restarted, then continued for another 50-odd minutes. (It hung for at least 10 minutes when it said “Less than a minute” remaining, but I’ve got an old-ish MacBook Pro, so yours may be a bit faster.)
Now that you’ve upgraded and had a chance to spend a little time poking around, let’s hear what you think about the cold kitty in the comments.
