Read Instructions Carefully
kernel from Apple's source and since they don't include XCPM in their source, this kernel is without it. This kernel is recommended to anyone who experiences instant reboots with the vanilla 10.9 kernel. With the exception of lacking XCPM, this kernel is completely unaltered from the vanilla stock version. A patched AppleIntelCPUPowerManagement.kext from 10.8.5 is REQUIRED if you expect CPUPM functionality.
