Painless JaS 10.4.8 to 10.4.9 update

[josh256]

What I backed up before running the update:

/mach_kernel

/System/Library/Extensions/AppleSMBIOS.kext

/System/Library/Extensions/IOATAFamily.kext

 

After running the update:

I backed up the new unpatched kernel, restored my backed up [semthex] version and restored the two kexts. Deleted /System/Library/Extensions.mkext and /System/Library/Extensions.kextcache (likely not needed), repaired permissions and rebooted.

 

Comments:

I'm not certain all these steps were necessary (EG: 10.4.9 may not knockout AppleSMBIOS.kext and IOATAFamily.kext like 10.4.8 did). If you haven't had to patch any of the existing nic/audio/video kexts you likely have nothing to worry about - if you have patched kexts (vs. new kexts such as titan) I'd recommend backing those up beforehand as well.
