I attempted a software update on my 2008 Mac Pro to 10.5.8 this morning and on restart a kernel panic resulted – grey screen with " … you must restart
you computer …" message in 4 languages appeared. After about 2.5-3 hours of phone support by Apple they had scheduled a service call to replace my
motherboard and memory card risers. They thought the software update and boot problem were not related.
A few hours later the tech called me back. He had just been in some training and asked if I had a 285GTX, which I did. My machine had originally shipped
with an 8800GT. He suggested I put the 8800GT back in, I did, and success!!
I originally had trouble with the 285GTX back in early JUNE, went on vacation, and on return read the 6/26/2009 sticky by tmurray that I should make sure
I reinstall the original driver for the 285GTX that came in the box with the card and install a special version of the 2.2 toolkit by following a link in the
sticky post. Perfect, with both the regular MAC and CUDA working fine.
After I was back up today I went to the CUDA MAC OS X page and saw version 2.3 with an explicit link for drivers for the 285GTX and 4800 cards which
stated these would work for 10.5.2 and later AS WELL AS Snow Leopard. So I installed this driver - 2.3.1 I believe was the number - reinstalled the 285GTX,
but again a kernel panic.
SO I GUESS THIS IS FOR THE FOLKS AT NVIDIA/APPLE - any idea when you will have compatible drivers for 10.5.8 and the 285GTX under which CUDA will
work properly? Granted, I have the 8800GT but the main reason I purchased the 285GTX was the need for double precision under CUDA, so the 8800GT
leaves me dead in the water. Plus, all my $450 285GTX is good for at the moment is for staring at and becoming angry/sad.
So under 10.5.8 I know of no available driver with which the machine will boot. Is there another driver in the works or other fix that would help?
