  • Note: I was unable to access the installation screen without -x

3.) Installed OSX Mavericks


4.) Restart


5.) Boot back to OSX Mavericks with bootable USB uusing -v -x cpus=1 npci=0x2000 GraphicsEnabler=No


6.) Installed the following kextFiles:

7.) Installed Clover Bootloader


8.) Attempted to start with -v npci=0x2000 cpus=1 GraphicsEnabler=No and various combinations of those flags and failed.


Any suggestions or additional information I could provide?

Two things:


Clover can be kind of tricky to configure properly.  Why not try to get Chameleon going first and then later you can switch to Clover?


You keep saying that you can only boot in safe mode.  But you never say what exactly happens when you don't boot in safe mode.  Does it hang?  Does it kernel panic?  Does the screen go black?  If it hangs, how about booting in verbose mode -v and taking a picture of the monitor when it hangs?

Apologies for not responding.  After a lot of digging and searching I'm finally booting with just -v in chameleon. My next hurdle is sound. I installed the AppleHDA from a thread over at that other place, but all I have is a virtual audio device that plays nothing.
