lapic_fix Kernel PKG Installer - for OS X Lion & Mountain Lion
Mountain Lion and Ivy Bridge Support Added!
Note: This does not work on OS X Lion 10.7.5 or OS X Mountain Lion 10.8.2. Apple has not released kernel sources yet, and because of that we can't get the kernel and patch it yet.
This is a package installer for the lapic_fix patched kernel by finntriel and maxhello. This kernel enables multicore support on laptops that have to use "cpus=1" to boot OS X. The vanilla kernel will be backed up to the Backup Kernels folder on the selected volume.
The lapic_fix patched kernel is compatible with Lion and Mountain Lion
Special thanks to finntriel and maxhello for making the Lion and Mountain Lion lapic_fix patched kernels. Also thanks to @shawnanastasio for making the scripts for the installer.
Tested on an HP dv7 4087cl running Lion 10.7.3 & 10.7.4 and Mountain Lion 10.8.
So download and enjoy! Comment if it works for you!
