Hmm, hope anyone can help. I updated to 10.5.3 and lost my Quartz/QE, but that was easily fixed by replacing the nvinject and nvidia kext's from my backup. Some goes for the ALC889 drivers.
But I've lost ACPI I think: my system won't power off or reboot when I tell it to. It just shuts down, goes black, but stays on. Does anyone know which kext I should restore? Thanks
