Shutdown / reboot problems on OSX86

When your OSX86 based machine does not want to shutdown properly (fans still running although all LEDs are off), try to install the OpenHaltRestart kext extension. You might want to use the Kext Helper to easily install the kext module.

Soundcard (ALC883) broken after 10.5.5 Update on OSX86

It can happen that after the 10.5.5 Update on OSX86, ALC883 based soundcards do not work anymore (not detected by OS X). To fix this, download the ALC883.dump.txt file and the AppleHDAPatcherv1.20. Unpack the latter, start the patcher and drag the dump file on it to patch the faulty kernel extension. Should also work with other ALC88X soundcards by using the appropriate dump file (Google is your friend for finding those).

OSX86 10.5.5 Update

To successfully perform a 10.5.5 update on OSX86 machines, you need to download the 10.5.5 update manually from the Apple webpage, open a Terminal and enter the following lines before running the update (and leave it running during the update):
  1. sudo -s
  2. while sleep 1; do rm -rf \
    AppleIntelCPUPowerManagement.kext; done
