Xenogenesis Posted July 4, 2008 Share Posted July 4, 2008 First let me say that this forum has been an amazing resource for installing and customizing OSX86, as well as discovering the limits of my other hardware (9600GT driver issue). However, I've searched high and low for a solution to this problem and I can't find anything other than a potential BIOS mod. That being said, if there is indeed information on this topic already floating around, let me apologize for posting this thread and would appreciate a reply to forward me there. So, my e8400 Core2Duo 3.0GHz (OC 4.0GHz) is showing up as only one core and zero processors in the Apple System Profiler. Other benchmark and widget hardware monitor apps only display one active core, as well. It seems that the vast majority of people have successfully enabled both cores to work on their OSX86 installs so I'm wondering what could be causing mine to either not display this information correctly, or to not use the other core. Here is my system information: Kalyway 10.5.3 e8400 Core2Duo 3.0GHz @ 4.0GHz ASUS P5K-E Motherboard, P35 chipset 2GB OCZ DDR800 RAM @ 887MHz 500GB WD hard drive Can I add a flag that will force recognition of both cores? Do I need to tamper with my motherboard's BIOS to fix this? Any and all ideas appreciated!

zakfontaine Posted July 4, 2008 Share Posted July 4, 2008 Look up the file /Library/Preferences/SystemConfiguration/com.apple.boot.plist (I THINK this is the file location.. I haven't looked it up in ages), and see if there's a tag that says "cpus=1" (without quotes). If so, take it off and try again. Antaholics helped me with this problem and that fixed it for me. Just delete that tag and everything should be fine. I had the same exact problem. Cheers.
