I did the Snow Leopard upgrade last night, and it went OK.
First step was to back up my MacBook. It’s an exaggeration to say that it had never been backed up–I do, or did, regularly back up files to my .Mac iDisk, but rarely if ever did a whole system back up. A $99 external USB hard drive let me use Time Machine for the first time and I let that run for about three hours. Once it ran, I kicked off the installer and went to bed. (Yes, tempting fate.)
In the morning, I came down to the login screen. After login, about five copies of Software Update popped up, prompting me to install Rosetta so that “HP IO Classic Proxy 2” could run. I cancelled all of them, and went to HP’s site, where I found a suggestion that I didn’t need that driver, or any of HP’s software. Seems that the printer drivers are included in Snow Leopard, and scan support has been added to the built in Apple Image Capture application. Um, yay. Scan support from pressing the printer button is gone, but I never used that.
I couldn’t get my Cisco VPN working, but I should be able to get a later version of the client from work on Monday. Even better, I’ll be able to try out the built in VPN support once I turn up my connection file (it’s in a directory that’s not indexed by Spotlight, apparently).
Best of all? The update did free up disk space. About 11 gigs. Now that’s what I call a good upgrade.
