----- Original Message ---- From: Read Weaver <rweaver at igc.org> So the 867MHz minimum that Apple requires isn't really a requirement? An Apple System's engineer told me that the big hang up is the video adapters. Leopards graphics us the GPU much more than the CPU. That is the reason for the 866MHz minimum. Tiger works fine on my 667 G-4 so I see not reason to upgrade that machine. It is time to think new hardware. 10.5 works well on my G-5 Tower. -------------- next part -------------- An HTML attachment was scrubbed...
