I think we need some more detailed information on your issue.

By the first look the open core debug file only contains success messages.

Please note that the open core debug file ends when it tries to boot into Mac OS. If you have problems booting OS X, you need to take a picture of the OS X error messages.

Try this config.plist for an 840 G4. Remember to edit for your particular graphics and supply your own platform info/SMBIOS.  If your particular CPU requires lapic to boot, make sure that is enabled.  You can download ProperTree from github to edit config.plist with a GUI.


  • Start with a minimum of kexts and drivers, disable any kexts u are not using in the Kernel section.

Add any kexts you need in the kernel section and make sure you are using the most recent kexts in the kext folder.
