Ciao Luke, well it might help if you know what exact cpu you have i.e. Intel Core 2 Duo T5500 is mine, try CPU-Z (freeware with Windows). I have both cores working fine on both of my hack OSX PC's. Maybe you use a "bad" OSX version but I wonder when you use the latest kernel everything should work OK. Maybe you did overclock your CPU ?

darkmental Posted May 7, 2007 Share Posted May 7, 2007 trye to set the fsb in the com.apple.boot.plist. I have Core 2 Duo 1.66GHz T5500 too, on Acer Aspire 5583. but can't run at fully 2 cores on Hack OSX 10.4.9 sh it show as this picture. P.S. On 10.4.8 it show 1.67GHz but when on 10.4.9 it show 2GHz (at cpus=1 of both version OSX) My com.apple.boot.plist is below How to set FSB that you told. Thank you. <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE plist PUBLIC "-//Apple Computer//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"> <plist version="1.0"> <dict> <key>Kernel</key> <string>mach_kernel</string> <key>Kernel Flags</key> <string>cpus=1</string> <key>Boot Graphics</key> <string>Yes</string> <key>Timeout</key> <string>10</string> </dict> </plist> Link to comment https://www.insanelymac.com/forum/topic/38723-centrino-duo-can-work-without-cpus1/#findComment-360973 Share on other sites More sharing options...
3phemeral Posted May 10, 2007 Share Posted May 10, 2007 My com.apple.boot.plist is below How to set FSB that you told. Thank you. Just add <string>fsb=200</string> on the line after <string>cpus=1</string>. So your new plist would be: <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE plist PUBLIC "-//Apple Computer//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"> <plist version="1.0"> <dict> <key>Kernel</key> <string>mach_kernel</string> <key>Kernel Flags</key> <string>cpus=1</string> <string>fsb=200</string> <key>Boot Graphics</key> <string>Yes</string> <key>Timeout</key> <string>10</string> </dict> </plist> Also, if your system is booting fine, you can reduce the Timeout to something like 5. This will reduce the time you have to modify options during boot to 5 seconds.
