msingh Posted January 1, 2009 Share Posted January 1, 2009 I have failed twice to do this. When I try to install the upgrade, the installation stops at 52% and I am asked to press the power button (Your system needs to restart). When I try booting, unsurprisingly, I get an unsupported CPU error and cannot boot. Is this a fixable (through DSDT) RTC bug, or is there no chance I can ever install 10.5.6 on this system ? System : 1.6 GHz Celeron on 1 GHz memory (Acer Travelmate 2420). Currently, I have almost everything working except for hibernate / resume.

quis Posted January 1, 2009 Share Posted January 1, 2009 Dunno, but DSDT patch works like a charm for me. Link to comment https://www.insanelymac.com/forum/topic/143976-is-it-possible-to-upgrade-to-1056-from-1055/#findComment-1022007 Share on other sites More sharing options...

Restart Leopard. Good Luck, Giorgio Thanks for the response, but I do not have an AppleIntelCPUPowerManagement.kext file in that directory. I also checked out the following link (which says pretty much what you are saying) : http://insanelymac.blogspot.com/2008/12/up...5x-to-1056.html It asks me not to restart. However, that is impossible as the update asks me to click restart *before* I even install the update (I am using Software Update). All in all, I am now fairly confused.

Beerkex'd Posted January 7, 2009 Share Posted January 7, 2009 Upgrade to Voodoo 9.5.0 kernel before upgrading. Just download and run the installer: http://code.google.com/p/xnu-dev/ Link to comment https://www.insanelymac.com/forum/topic/143976-is-it-possible-to-upgrade-to-1056-from-1055/#findComment-1030848 Share on other sites More sharing options...
