To update, you can you old manual : manual

or shorter way:

1) make sure you have dsmos/appledecrypt and appleintelcpupm disabler kexts installed to /Extra

2) update

ich10r users - you dont need legacy kexts for ich10/ahci anymore, 10.5.7 supports ich10r out of box (since new macpros has ich10r), need only legacy ahciblockstorage, to fix orange icons.

Important notice, legacyhda may not work with newer applehda.kext from 10.5.7, you will need either make sure you legacyhda works with 10.5.7 or use applehda.kext from 10.5.6 (alc889a legacyhda from stickpin and friends need to be updated)

You still need to carry abotu whatever custom drivers you have.

If you use chameleon, or other bootloader with smbios replacement support, better to make identify of your machine to be some imac or something else, MacPro4,1 identify may result in kernel panic, or you need to remove AppleTyMCEDriver.kext with this script, durring installation :

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

Good luck


How to update to 10.5.8

install Disabler.kext

install this Dsmos.kext ( a bit updated to be present in mkext)

reboot

create backup of Extensions folder. just in case:

sudo cp -rf /System/Library/Extensions /System/Library/Extensions_old

update !

if something is wrong with your drivers after update - u have a backup

some info:

for radeon HD 48×0 users, binary of Motmot wasnt updated, so if u used patched framebuffers, should work fine still.

for radeon HD 4870×2 4890 4830 users - you will loose qe/ci/3d after update, wait for proper patch.

Dont remove AppleIntelCPUPM.kext until install finished, or it will stop with error.

If your using a patched kernel remember to reinstall it again before reboot

thx netkas

Update: Here some fix

Will any of these work on an amd system????

It should work with AMD, just after update install once again your patched kernel like voodoo or whatever u have

Another succesful update via "softeware udate"...

i updaten my 10.5.6 to 10.5.7 and now i have to restart my computer everytime i insert a usb is there a way to fix this? everything was perfect when i had 10.5.6

try using this to fix the issue

it didn't work

Use your previous seatbelt.kext in Extension Folder
It's must be seatbelt.kext.orig after you update 10.5.6 to newer version 10.5.7
Drop seatbelt.kext.orig Folder to somewhere ( eg Desktop ) and rename it to seatbelt.kext. Afterward drag and drop it back to Extensions Folder, Autheticate, use Terminal to load kext :
sudo chmod -R 755 /System/Library/Extensions/seatbelt.kext
sudo chown -R root:wheel /System/Library/Extensions/seatbelt.kext
loadkext /System/Library/Extensions/seatbetl.kext
delete Extensions.mkext if needed, repair permission and reboot.
I/ll be glad if it work with you ^^

ok i did it
i replaced it and even verified that the versions are different
but when i plugged my usb in it didn't work. but thats not all
i was going through my extensions and deleting the .kext.orig files and my usb randomly mounts :S HUH?

hey i have a huge problem now..
