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. Link to comment Share on other sites More sharing options...
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. Link to comment Share on other sites More sharing options...

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. Link to comment Share on other sites More sharing options...
