So, I upgraded my desktop Mac Pro with 10.6.3 last night, and now it boots to a black screen just after the Apple logo vanishes.
I have a Sapphire 4870 w/512MB that I'd previously used this tool to Flash (the prior version, before Zeus). I had to build my own firmware for the card with instructions I found on these forums because the included firmware was incompatible with my specific part. But once I'd done that and flashed in my ROM, everything seemed to be great. The Apple firmware likes it (still), so I can Option boot and everything. 10.6.2 was happy with it and worked great, and Windows 7 is also (still) happy with it.
So, I'm not sure what the deal is. Where do I look? Did 10.6.3 break something for anyone else? I assume the black screen (it's not hung, the machine is running, it just seems to think it's 'headless') is an indication that the ATI driver is no longer loading, but I thought flashing the card meant I didn't need to modify the stock driver anymore? Is that wrong? I didn't think I was using a modified driver under 10.6.2, but I can't be 100% sure because I had tried a few tricks before I learned how to make my own ROM....
If I boot to command line (single user) is there something I can do to see how the card is identified vs what's in the driver's plist? I do get video at that point, so it wouldn't be tough.
Thanks for any pointers.
