I sat down a few minutes ago to attempt to install the copy of Aperture 1.5 that member fuchsdh generously gave me a weeks ago(as part of the lot of the big lot of software he gave away). I attempted to install it on my main Quicksilver, which is my main computer for photography purposes. Interestingly enough, it wouldn't install, as I didn't meet the minimum processor requirements. As per the install documents, I need either a G5 or a 15/17" PB with a 1.25ghz or faster processor. I have an appropriate video card(I'm using a 9600XT, which has full core image support), and I would think that a pair of 1ghz 7450s with 2mb of L3/core would give better performance than a single 7447A with no L3, unless there's some sort of instruction set the 7447A supports that my QS does not. As a corollary to that, I wonder if it would install on my(now) dual 1.6 Quicksilver, which has 7447A. I would need to put a core image card of some sort in it, which I think I could come up with(assuming a 9600 Pro would play nice, or at least I could use the PCI 5200). I'm away from that computer at the moment, so can't test it and won't be able to until late tomorrow or Monday. So I guess my question is-does anyone know if there is something in the coding of Aperture that would prevent it from running on the 7450, or can I bypass the installation checks and have it work fine as many of us do frequently with Leopard. If the latter is the case, I could always put my Quicksilver in TDM and attempt an install from a supported Powerbook. If no one has a direct answer, I'll try doing just that tomorrow and see what happens.
