In Topic: Anyone try installing Mavericks DP4

24 July 2013 - 01:12 AM

Exact same thing happened to me after installing DP4 (as well as Logic Pro X if that makes any difference).

 

When I boot without -v, it boots, then right before it goes to the desktop, a white screen appears with the spinning loading icon in the center of the screen. Booting in verbose leaves it at a black screen with a cursor in the top left corner...Wait like 3 minutes and the monitor looses signal and never comes back on...but it's still up and running. I've never seen anything like this before and have no clue where to start with troubleshooting. Has anyone found a solution to this problem?

 

My specs: GA-H61N-USB3, GeForce GT 630, 4gb RAM, i3-2105

 

 

When it's stuck on the spinner unplug your monitor for a few seconds then plug it back in. Tell me if that fixes the issue.

AMD 7970M

 

Cause of my issue:

 

When both my external monitor (HDMI) and laptop internal screen are being used, it will freeze during boot.

 

Workaround:

 

I have to unplug the HDMI display and plug it back in. This unfreezes the boot process.

 

This issue is new for me in DP4.

It has been working fine with full QE/CI, sleep and etc for me until the DP4 update. After DP 4 It can only start in safe mode. In regular mode it just freezes with an unrelated log message during boot.

Using "Buri" framebuffer. HDMI works OOB. Internal LCD doesn't work OOB and requires patching the frame buffer. In order to fix that modify the first connector of Buri,

 

from:

02 00 00 00 00 01 00 00 29 05 01 00 10 00 05 05

 

to:

02 00 00 00 40 00 00 00 09 01 00 00 00 03 00 05

 

 

This is the result of reading http://rampagedev.wo...r-personality/and the referenced articles. I also got direct help from the author of rampagedev. The offset of the frame buffers in the Mavericks ATI7000Controller.kext is different from what's posted in rampagedev and other sites. So you have to search for the connector HEX data directly rather than looking up the framebuffer offset.

 

Hope this helps.

I have the same exact issue with my AMD 7970M in both Mountain Lion and Mavericks and have not been able to solve it. I also tried swapping a friend's nVidia 680M in there and even though it pretty much worked OOB, I had the same color banding/depth issue. I have experimented a lot with modifying the framebuffer (Buri in ATI7000Controller.kext) to no luck. The following is the original connector and the modified one that is working fine but has the same color depth issue with my 7970M card:
