what’s new in 10.6.2：
64-bit kexts for intel graphics
64-bit atheros driver
support for desktop radeonhd 43xx/45xx/46xx (only dvi output works yet, dvi2vga dongle doesnt work) with beta booter(dont forget to unpack before installing;) )
Bye bye atom, should be fixed as soon as apple releases kernel sources or use kernel&system.kext from 10.6.1
better opencl support for radeons 4 series, also opencl support for 46xx cards
Something I forgot to mention
Radeon users need to use PCEFI 10.4.1 or 10.5, pre 10.4 will cause panic in ATIRadeonX2000.kext
There is panic with geforce7 cards and 64-bit kernel mode, use 32-bit kernel mode
New core i5/i7(8xx) is supported by vanilla kernel now.
How to update – it’s easy.
--------------------------------------------------------------
Use any disabler for AppleIntelCPUPowerManagement.kext, for example – NullCPUPM.kext, install it to Extra mkext and reboot, of course if you made AppleIntelCPUPM to speedstep your cpu, you can skip this step.Make backup of your kexts, you might need some.
Remove SleepEnabler.kext if you use it, this is very important step, old sleepenabler + new kernel = panic.
Hit the update button, if you need to edit some kexts AFTER updateand BEFORE reboot – download and install update from apple site.
After reboot – re-add your device-ids to kexts where you need it and enjoy.
------------------------------------------------------------
Updated sleepEnabler for 10.6.2 – link, I binpatched the old one, so don’t ask for sources, I don’t have them, install(if you want) only AFTER updating.Radeon 4830/4850/4870×2/4890 users, tired of adding device-id to ATI4800Controller.kext after every update ? Use this kext in Extra mkext.
Also, for atheros users, here is legacy kextfor it, to stop thinking about dev-id insertion after every update, wemade it together with XyZ, add your dev-id to it in two places andinstall to Extra mkext, the unique feature of it is ability to load oldkext in 32-bit mode and new kext in 64-bit mode, this is needed becausesome users have problems with signal level and new driver.
Radeon 4830/4870×2/4890 users – you need to install this pkg – qe_ci_exotic_10.6.2
Netkas I just wanted to mention there is additional nVidia support with the update aswell. All of the G200 series mobile gpus (the ones built off the 40nm chipset) are working now in 10.6.2. This includes ( but not limited to) GT1×0m series, GT2×0m series, GTS2×0 series, and GTX2×0 series. Pre-10.6.2 QE/CI worked but was rediculously slow and full of artifacts everywhere. 10.6.2 has full support, and everything works great (even out of the box on some systems with GraphicsEnabler
