About This File

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.

OVERVIEW

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.

COMPATIBILITY

The lapic_fix patched kernel is compatible with Lion and Mountain Lion

THANKS TO

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!

@eruiz00 Is "Kernel Flags" "cpus=1" in your Boot.plist? If so, remove it. Select the proper version of the kernel for your OS X version. @Dragon-chen If you have to use "cpus=1" to boot Mac OS X without kernel panics, then this should work. @baby_demon Unfortunately, third party kernels cannot use FaceTime and iCloud. This is the case with all third party kernels and can't be fixed.

@baby_demon Snow Leopard? This kernel is for Lion only.

Guys, I'm in the process of creating an application that replaces the lapic_fix kernel with the vanilla kernel.

@Dragon_Chen: Finntriel is correct with this. This kernel is only for 1st generation and Sandy Bridge Core i processors. If you need Ivy Bridge support, install BridgeHelper by {censored}.

@k8l: I'd recommend using Carbon Copy Cloner or another tool to make a full bootable backup. If you can't or don't want to do that, you can just rename the mach_kernel file. Open up Terminal, then type

sudo mv /mach_kernel /mach_kernel.bak

It should rename mach_kernel to mach_kernel.bak. I'd still recommend the bootable disk clone over this, though.

I'm working on integrating this feature into the installer.

@Dragon-chen: It won't work with Ivy unfortunately, because the Ivy kernel only is in the special build of OS X 10.7.4 for MacBook Pro Retina editions.
