I followed the tonymacx86 Sandy Bridge instructions.

After install system does not come up but only sits at Apple boot up screen.

System does boot if you use the iBoot Legacy CD.

I am running a Intel DH67BL with i7 2600.

Any help would be greatly appreciated.

Thank you,
Rob.
 
I had same problem. Try this one – write this text in to com.apple.Boot.plist.
Set in BIOS hpet=64.


<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
<key>Kernel</key>
<string>mach_kernel</string>
<key>Kernel Flags</key>
<string>arch=i386 -force64 PCIRootUID=1 busratio=29</string>
<key>GraphicsEnabler</key>

<string>1</string>
<key>Legacy Logo</key>
<string>Yes</string>

</dict>
</plist>
 
OK, putting in cpus=1 and GraphicsEnabler=No allowed me to boot into single user mode.

When I try to run fsck I get the following:

** /dev/rdisk0s5
Can't initialize disk cache
/dev/tdisk0s5 (hfs) EXITED WITH SIGNAL 8

This only happends when I boot of the harddrive.

If I use iBoot legacy CD I can get into single user mode and run fsck and after exit system boots.

Does anyone know what options the iBoot Legacy CD use in com.apple.Boot.plist?

Thank you,
Rob
