After seeing an article today from Computerworld titled Leopard at six months: Does it live up to the early hype? and getting this mail from a CPU Upgraded G4 tower owner (happily running OS X Tiger) considering upgrading to Leopard I thought I'd ask for feedback from readers running Leopard for awhile on their CPU Upgraded Macs to see what their current experiences were (was it worth it, recap on any issues, etc.) - If you're running OS X Leopard on a CPU Upgraded Mac, let me know what your experience has been (satisfied with the decision to upgrade? Performance OK? Any issues seen with your hardware or software?, etc.) Please include the following info in your report - Mac system details (model, etc.), CPU Upgrade details (brand/model/speed), Any 3rd party hardware installed or attached (PCI cards, Graphics card, FW or USB devices, etc.), Info on Software apps, addons, startup/login items, etc. (especially if you saw a compat. issue), How satisfied are you with OS X Leopard?
