How to update to 10.5.2./10.5.3

UPDATE: doesn;’t work with software update, need to have dmg/pkg.

Open Terminal/Finder/etc, go to System/Library/Extensions. start installing update.

Monitor System/Library/Extensions folder, once AppleIntelCPUPowermanagement.kext appears there – remove it immideatly.

u can use this little script for it, run as root, before starting upgrade

while sleep 1 ; do rm -rf /System/Library/Extensions/AppleIntelCPUPowerManagement.kext ; done

once update finished, press ctrl-c in terminal window, to stop script, don’t press restart !

after it, open this file in textedit – /System/InstallAtStartup/scripts/1

find there string /System/Library/Extensions/Dont Steal Mac OS X.kext

and replace with this string /System/Library/Extensions/dsmos.kext or r3d3 if u use r3d3.

then save it.

now u can recover ur applesmbios/applehda/etc (didn;’t u forget to make backups b4 running update ?)

and finaly press restart.

on first start it will do smth, without booting to gui, then it will reboot, it can take about 3-4 mins, then it shuld boot normaly, if u didn;t  forget smth.

of course it’s all for intel core 2 based cpus and intel mobos. and pc_efi.

other users can use 10.5.1 kernel/system.kext with 10.5.2 system (like amd users or pentium-d)

9.2.0 kernel with fixed shutdown, UPDATED

It’s in #10.5 channel topic on

ToH kernel with fixed shutdown (and reboot).

Update: speedstep-less kernel, which can sleep, added to irc.

P.S. for  intel/amd sse2/sse3

Natit, again ? yes

This is a natit for Radeon hd cards.

works with Radeon HD 3870×2, 3870, 3850 , 2600pro, 2600XT

added support for all known 2×00 3×00 device-ids, jsut in case. maybe

somebody will be able to get working framebuffer on 3600 or etc.

New natit

For 2600pro/3850 need to install white menu fix (to /System/Library/Extensions)

Note to 3870X2 users, your card will work as two 3870(just like two 2600XT in MacPro),

in case u have more then 2 dvi ports.

otherwise it will work as one 3870.

Full pkg for 3870X2 is available on IRC.

P.S irc:// #radeonhd

P.S.S. we hit half-million visitors(and around 800000 vists).

Radeon HD 3870 X2 works in OSX

Yeah, one core only tho.

This situation is identical to having crossfire system booting OSX.

OSX can’t use crossfire, so key have to be set only for one display device.

here is screenshot of IOregistry explorer explains it a bit

And here is sshots of working system

because of need to set keys for only one display device, current natit can’t work with

ATIRadeonX2000.kext, but gfx-string can !

also ATIRadeonX2000.kext need some patching(use any hex editor and replace
07 95 with 0F 95, it will make all 9504-950f cards works (lol))
and adding 0x950f1002 devid to plist

Thanks to blackknight for creating gfxstring, making tests and screenshots.

GFX-strings stuff for 3870 x2

New natit for radeonhd

This new natit automaticaly dumps your video bios and inserts it to ioreg, no need to hardcode it anymore.

Also here is support for 3870 x2 (framebuffer only) and 3650(no tested, jsut added).

3850 ,2600pro users – get a white menus fix from #radeonhd topic on irc://

new natit

Some status report.

There is a lot of same questions, to answer them all i wrote little status report

1) 2400 mobility doesn’t work with internal display

2) working Radeon HD cards for osx – 2600 XT, 2900 XT/pro, 3870.

3) Cards needs some fixes (like2600pro fix or devid edit)  2600pro, 3850

4) Speedstep kernel can’t sleep, stop asking about it.

New natit for Radeon HD cards

this natit works fine with umodified kexts, especialy on 10.5.2

tested to work 2600XT, 3870, not tested 2900, but i guess it should work,

will not  work 2400, because no testers i had.

Works dvi, vga, dual-head, sleep may work or may not work, depends on cards,

because i hardcoded bios dumps to Natit, u can change it in Info.plist.

9.2.0 speedstep kernel and new smbios for pc_efi

U can find new universal speedstep kernel in #10.5 topic in irc network.

Thx apple for releasing sources.

also, here u can get new smbios for pc_efi, it adds more memory informatio to profiler

(on 10.5.2), AppleSMBios-27,

if that one doesn’t work for u, try iGuru’s smbios :
