I am setting up a brand new Mac Pro someone for their Christmas present (lucky them ), and though it is super fast after it starts up, startup takes longer than on my MBP. More specifically, when you first press the power button, a gray screen comes up and it takes about 10-15 seconds for the apple logo to appear and the hard drive to begin thrashing. My main theory is that it is testing the memory before it starts to boot (I know that a lot of PCs do that). I has a lot of memory (4GB), and it is configured with eight 512MB memory chips, which supposedly is not ideal because of latency issues). Anybody have any ideas of what the deal is?
