netcreator Posted July 9, 2009 Share Posted July 9, 2009 Try to set up with OSX86Tools: 1) Choose "Modify About this Mac" from the main panel; 2) Choose "Autoset CPU Info". Printscreen attached.

MGJulius Posted July 10, 2009 Share Posted July 10, 2009 For the one core issue what kernel do you have installed. To find out open up the terminal and type in: uname -a Then post the info here. Also check your com.apple.Boot.plist in /Library/Preferences/SystemConfiguration/ for the "cpus=1" flag Link to comment https://www.insanelymac.com/forum/topic/174305-core-2-quad-dont-recognized/#findComment-1196941 Share on other sites More sharing options...
ampAIR Posted August 1, 2009 Share Posted August 1, 2009 hi there, i have (quite) the same problem, i have a dual xeon setup and osx (iDeneb 1.3) also only recognizes only 1 core out of 8... I already tried: booting with "cpus=8" (I don't have a "cpus=1" entry in my apple.boot.com.plist) setting MAX CPUID to Disabled Enabling ACPI APIC results in an immediate reboot loop my uname -a output: Darwin sebastian-vs-macpro31.local 9.5.0 Darwin Kernel Version 9.5.0: Wed Sep 3 11:29:43 PDT 2008; root:xnu-1228.7.58~1/RELEASE_I386 i386 any help will be appreciated, i need those cores for video rendering. sebastian Link to comment https://www.insanelymac.com/forum/topic/174305-core-2-quad-dont-recognized/#findComment-1214631 Share on other sites More sharing options...
