With Pacifist you can install any kext or file from an update/package without having to install the rest, for example, to update my iatkos 10.5.2 to 10.5.4 I downloaded the 10.5.4 combo update from apple downloads, then i open it with pacifist and select to install all the files except for the extensions and mach_kernel and other harmful files for my installation.
So from the convenient combo update you can extract and install the single System.kext you need.
I think you need the 10.5.2 version of System.kext for 9.2.0.
Hope this helps.
Dumb question. Does this not work with the 10.5.5 update???
ok now I'm installing using Kalyway's 10.5.2 and I want to update it to either 10.5.4 or 10.5.5, and I know how to do this. What I don't know is do I install the kernel patch before, or after I update, and which kernel patch would I need?
