MOUNTAIN LION 10.8(12A269) Darwin 12.0.0 HP USERS WITH AN INTEL i3, i5, or i7 sandybridge processors. CPUS=1 FIX FOR HP LAPTOPS
ML mach_kernel (recompiled) - compiled without adding "export BUILD_STABS = 1" in line 1 of ~/xnu-1699.22.81/makedefs/MakeInc.def
said in the forum it wouldn't compile without that line but it did compile. Both kernel seems to work. Please test and let us know which one is better...
