I'm just curious. I see Leopard will be out in a week or so. I've never upgraded a system before so I have a couple of questions. First, am I right in assuming Leopard can be used to upgrade a system that doesn't use the Intel chip? Second, I assume it would be useless - or impossible - to install the new OS in my G4 tower, which is 9.2.2, but what about my relatively new iMac which is 10-something? Forgotten exactly. Would it be worth or necessary installing the new OS in that model? Finally, and this from a non-techie type, how difficult is it to install a new OS? What are the problems, if any? jim ----------------------------------------------------------- MUGLO information at <http://www.freewebs.com/muglo> Manage list subscription options at <//www.freelists.org/list/muglo> -----------------------------------------------------------
