Field Note #1 @jazZbaR 2008-12-04

i´ve installed the CPUdisabler.kext but after updating to 10.5.5 i have the AppleIntelCPUPowermangement.kext in the extensions-folder. is that normal? i delete this manually as the updating process.

Field Note #2 @LawlessPPC 2008-12-05

yeah it just disables apples kext making it safer to update

Field Note #3 @EncryptedSoul 2008-12-05

If you have Intel, why not just use DSDT.aml? It seem's to be the newest "work-around" instead of a disabler kext.

The reason AppleIntelCPUPowerManagement.kext stop's hack's from booting is because it look's for HPET features in the processor.(which most board's don't support)

Using DSDT.aml assign's an IRQ to the processor for HPET.

Doing this allow's AppleIntelCPUPowerManagement.kext to load and run natively, so you can do away with disabler's and successfully run Apple Update's.

*** As a side note, DSDT.aml also fixes a supposed bug in AppleRTC.kext… A kext that will also give trouble to hack's in 10.5.6... Personally, I think by the time Apple releases 10.5.6, the bug issue won't exist, so RTC won't be an issue. Just an assumption…
