This guide is fully updated now. Do not worry from any posts below. I have included all the new kexts and files to backup to avoid as much problems as possible.
Requirements:
1) 10.4.9 Delta updater (from Apple's website)
2) 15-30 minutes of your time
Known issues (as far as I know):
Disk images fail to mount and iPods not being recognized. This has been fixed by backing-up 10.4.8 system.kext (included in the updated instructions).
GMA900 did not work after update (see notes below)
Seps:
1) Open up the terminal and type "sudo -s" then "your password" then the following (line by line):
CODE
cp /mach_kernel /old
cp -R /system/library/coreservices/loginwindow.app /
cp -R /system/library/extensions/AppleSMBIOS.kext /
cp -R /system/library/extensions/AppleACPIplatform.kext /
cp -R /system/library/extensions/AppleAPIC.kext /
cp -R /system/library/extensions/IOATAFamily.kext /
cp -R /system/library/extensions/system.kext /
2) Keep terminal open.
3) Open disk utility and keep it open
4) Run the delta installer (AND DO NOT RESTART---IGNORE THE INSTALLER WINDOW)
5) Open terminal and type the following:
CODE
cp /old /mach_kernel
cp -R /loginwindow.app /system/library/coreservices/
cp -R /AppleSMBIOS.kext /system/library/extensions/
cp -R /AppleACPIplatform.kext /system/library/extensions/
cp -R /AppleAPIC.kext /system/library/extensions/
cp -R /IOATAFamily.kext /system/library/extensions/
cp -R /system.kext /system/library/extensions/
rm -rf /system/library/extensions.*
6) Open disk utility and repair permissions for your OS X partition
7) Pray and restart the system (unless you have GMA 900 --> read below)
8) Post pictures of your 10.4.9
This has been tested on my computer and fully working. No problems until now.
GMA 900 users: (Do these steps after finishing above steps)
1) insert your JaS 10.4.8 DVD
2) navigate to system>installation>packages (on the DVD)
3) install JaS.10.4.8.GMA.900.support.pkg
4) repair permissions
5) reboot
