I am officially Jaguar-ed. So far, so good. I will recommend to you folks out there who have not installed it yet, to use the Archive and Install option… it’s a new install option that archives everything from your previous system (assuming you are running OS 10.x already)… very handy.
Also, refer to this sidebar from the current MacWorld mag Migrate to Jaguar with a Clean Install. There’s more info at this link than in the printed mag.
I’ve spent almost the whole afternoon tinkering with this OS. Me likey.
