davecool Posted September 6, 2008 Share Posted September 6, 2008 Hi all. I searched all around the forum and on Google for this answer, but couldn't find one. I built a OSx86 box about a month ago. It's running fine, but I'm concerned that it's running in 32-bit mode, rather than 64-bit, given that the hardware supports 64-bit. Intel Q9450 Core 2 Quad Asus P5K Deluxe WiFi-AP 4 GB DDR2 800 RAM (other hardware too, but hard drives wouldn't affect this) I installed Leopard 10.5.4 from iATKOS 4i with the vanilla kernel. The motherboard supports 64-bit, the CPU certainly supports it. The vanilla kernel should be running 64-bit on this hardware, but it's defaulting to 32-bit. I have confirmed this by running "arch" and "uname -a" in the Terminal, both report i386. I can't run any 64-bit applications. Chess, for example, crashes immediately upon launch. Any thoughts? I've seen other OSx86 systems run in 64-bit mode, so I know it can be done. Thanks, David.

Donw35 Posted September 7, 2008 Share Posted September 7, 2008 those same commands return that my OSX is running I386 as well but I am able to run chess.

davecool Posted September 16, 2008 Author Share Posted September 16, 2008 Installing 10.5.5 fixed the 64-bit issue. I can now run 64-bit apps! Sweet.
