Lyve Posted May 5, 2011 Share Posted May 5, 2011 Hello, I successfully installed Snow Leopard on my machine by using Empire EFI and a SL Retail DVD. Everything was fine, I even didn't need any special arguments while installing. After installation, I could easily upgrade to 10.6.7, so far so good. I didn't install anything else yet except NVEnabler for my graphics. The problem is, in the Activity Monitor, I see 4 Graphs for all 4 Cores of my Core 2 Quad Q6600 processor, but 3 of them are black and the performance of the machine is bad. I assume that 3 cores are completely idling, they seem to do nothing. The "About this Mac" box lists my processor as 1 CPU - 4 Core Intel Xeon @ 2,73Ghz. The clock is correct, but it's not a Xeon, only a Core 2 Quad. My machine is a Asus P5Q Motherboard, 4GB of DDR2 RAM, A Geforce 9800 GT graphics and the CPU mentioned above. Is this a common problem? Any advice? Thank you very much. Nils Link to comment Share on other sites More sharing options...
Gringo Vermelho Posted May 6, 2011 Share Posted May 6, 2011 Apple don't ship any Macs with Core 2 Quad CPUs. Your bootloader automatically convinces OS X that you have the Xeon equivalent. This is good for compatibility. Enable ACPI 2.0 and ACPI APIC in the BIOS. Enable all advanced CPU features except CPUID Limit. Use a MacPro3,1 smbios.plist in /Extra (find one via the Forum search) Upgrade to Chameleon 2.0 RC5. Read about the new features here: http://www.insanelymac.com/forum/index.php?showtopic=225766 But try to find a newer version. I've compiled and posted a few lately, look in my previous posts. There's an install guide as well. Link to comment Share on other sites More sharing options...
rrprime Posted May 7, 2011 Share Posted May 7, 2011 boot using -v to see all you cpus and count which are working or not. Try the legacy kernel and Gringo Vermelho is right do that and then this if you can't get it to work Link to comment Share on other sites More sharing options...
