About This File

So for a few days we've been working on a user friendly way to easily apply a lapic fix to kernels. This is the result of our work biggrin.png

If you don't know what this is used for, it fixes an issue that causes booting to hang on HP laptops with Intel i processors.

Simply select the kernel you want to patch, choose if you want to create a backup, select patches to apply, and press the patch button.

Should work on all past, present, and future kernels released by Apple. Even works on the developer's preview of Mavericks victorious.png

Unlike previous lapic kernels, the patches this app applies allow FaceTime, iCloud, Dictation, etc to work without any problems.

If your curious about what it does, read about it here on my blog.

UPDATE: Confirmed working on 10.8.4 by Yuan Lukito here.

UPDATE: Confirmed working on 10.8.5 by BadNumberBoy.

UPDATE: Confirmed working on all Mavericks previews up to DP5 by lightskreen here.

UPDATE: V0.7 adds support for all remaining Mavericks developer previews, GM, and official release. Special thanks to noname.

Please consider donating if your satisfied with my work. My donation page is here. Thanks smile.png

@skypete Nope, just for Intel processors. AMD is much more complicated.

This kernel just fixes the issue with getting this kernel panic on boot: Local APIC Error, ESR: 64\n" @/source/xnu/xnu_1504.15.2/osfmk/1386/lapic.c:704

@atleeit Lol, what's up with you always having problems with my kernels? Did you try doing that ever you did last time to get my 10.8.3 kernel working? :eagerness:

And are you still using Clover, cause gsyl added my lapic patches to its kernel patching feature. You need to have Clover with revision 1731 or greater, and add the following to your config.plist:

KernelAndKextPatches

KernelLapic

@sherlocks Hey!! Haven't heard from you in forever.

Just got a friend to send me the mavericks kernel, and it has the same patch patterns as all the others. No need to worry about lapic problems with 10.9 :D

Thanks for checking out my blog :eagerness:

@rwang1000 What mac version are you using? Try booting with -f to see if that helps. I notices that some people needed to clear their kext cache in order to get a new kernel to work.

If that doesn't work, then if you created a backup of the original kernel using my program then use the following boot parameters to use it:

Kernel=/mach_kernel.bak cpus=1

Then send me the original and modified kernel so I can take a look them.

@donovan6000 I use 10.8.4 with Chimera 2.1. I tried the -f flag with no avail. Right now the boot stops before Mac Framework is loaded. An error message comes after all of the kext loads but it reboots too quickly for me to read. Here are the kernels.

@donovan6000 I repatched the kernel with version 0.6, and I am still having trouble. I videotaped the boot process and found that chimera reads all of the kexts and then displays the boot flags used. Then the computer restarts.

With patched kernel system can't build kernelcache and reboots.

10.07.13 23:54:40,426 com.apple.kextcache[14183]: Child process /usr/sbin/kextcache[14184] exited due to signal 11.

@calin1975 Haven't tested it personally, but it should work for. By default my program creates a backup of the original kernel, so there's no harm in testing it out. Also it'll tell you if it successfully patched the kernel or not, so it's worth giving it a try.

@donovan6000 There are the new kernels. Thanks for all your help. One thing of note: although OSX86 says the patcher is v0.6, the files I downloaded says the patcher is still v0.5. Perhaps thats the problem?
