Yep, you're right, Jim, it
was the G5, and it's no disaster, but it took about 15 minutes to pull in the almost 7K tunes I've got, and adjust the volume, organize and do whatever. I hadn't updated because I was afraid it might not run it, but it appears to be doing fine.
I finally got the MacBook up and running and reloaded with new software;
now I have to get all my pics from iPhoto & Aperture into, and I'm hoping that it'll be able to read the old files, because there is 109 gigs of stuff in the pictures folder. . .
