strelok1911 Posted December 12, 2010 Share Posted December 12, 2010 I removed my NullCPUPowerManagement.kext without DSDT and nothing happened. My system does not need it apparently. You should keep it, nothing is being affected afaik if you keep it.

Gringo Vermelho Posted December 14, 2010 Share Posted December 14, 2010 You should keep it, nothing is being affected afaik if you keep it. Right, except for CPU power management. Try upgrading to Chameleon 2.0 RC5: http://www.insanelymac.com/forum/index.php?showtopic=225766 Link to comment https://www.insanelymac.com/forum/topic/239655-removing-nullcpupowermanagement-with-dsdt/#findComment-1601881 Share on other sites More sharing options...
MaLd0n Posted December 14, 2010 Share Posted December 14, 2010 the dsdtpatcher (fassl) http://www.insanelymac.com/forum/index.php?showtopic=133683 has the option -newHPET that generates an HPET "standard", you can try it! I have seen some cases like his and unfortunately had no solution do it with the original DSDT that its the HEPT was modified Link to comment https://www.insanelymac.com/forum/topic/239655-removing-nullcpupowermanagement-with-dsdt/#findComment-1601893 Share on other sites More sharing options...
