Bubu77 Posted December 5, 2009 Share Posted December 5, 2009 Hello, I installed Snow leopard 10 days ago. After few search, I solve few problems (sound...). I still can't shut down my computer: the fan remains ON... That's why I tried i installed CHUD.pkg and then PowerOff fix. I also tried OpenHaltRestart.kext I still can't power off or reboot my computer correctly (I need to keep power button pressed 5s to power off when screen is black) and now, my CPU is not recognized anymore. I can read: "processor 3Ghz unknown" and before I was used to read "Core Duo 2 3ghz". Do you have any idea to reactivate the second core? If you also have a solution for the power off/ reboot problem..... Thanks a lot Snow leopard 10.6.2 kernel Darwin 10.2.0 - Gigabyte EP35C-DS3R - Core duo 3Ghz - Geforce 9600GT - 4Go RAM DDR2 Link to comment https://www.insanelymac.com/forum/topic/200994-how-to-re-activate-core-on-dual-core/ Share on other sites More sharing options...

kalel83 Posted December 5, 2009 Share Posted December 5, 2009 what's in your com.apple.BOOT.plist file? Link to comment https://www.insanelymac.com/forum/topic/200994-how-to-re-activate-core-on-dual-core/#findComment-1351298 Share on other sites More sharing options...
Bubu77 Posted December 5, 2009 Author Share Posted December 5, 2009 what's in your com.apple.BOOT.plist file? here what I have: <plist version="1.0"> <dict> <key>Kernel</key> <string>mach_kernel</string> <key>Kernel Flags</key> <string>arch=x86_64</string> <key>GraphicsEnabler</key> <string>y</string> </dict> </plist> Link to comment https://www.insanelymac.com/forum/topic/200994-how-to-re-activate-core-on-dual-core/#findComment-1351370 Share on other sites More sharing options...
xian1243 Posted December 5, 2009 Share Posted December 5, 2009 here what I have: <plist version="1.0"> <dict> <key>Kernel</key> <string>mach_kernel</string> <key>Kernel Flags</key> <string>arch=x86_64</string> <key>GraphicsEnabler</key> <string>y</string> </dict> </plist> I just want to let you know, that your core is NOT disabled. When unknown CPU comes up in about this mac, it just means that your SMBIOS kext isn't working right. It has nothing to do with CPU usage, it's merely info on your CPU. Don't worry. More proof: if it was disabled, your boot.plist would be different. Solution for the About this mac problem: install Chameleon RC2 bootloader (google search Chameleon EFI, it's easy to find), install that to your Leopard partition, and if it still doesn't work, look in /System/Library/Extensions for something like SMBIOSEFI.kext, which is conflicting. Delete it, and reboot with the -f flag. DO NOT DELETE SMBIOS.KEXT. That is the normal system kext which you need for Leopard to work. If you have any questions, I'd be sure to answer them, and I'm sure someone else here can help too. Like I said, don't worry about it showing unknown in about this mac, YOU ARE USING 2 CORES ALREADY. Regards, Chris EDIT: I just noticed you already have Chameleon, so just look for the kext that is causing the problems. Normally Chameleon injects that info but if a custom SMBIOS EFI kext is in there it won't work.
