Question

Mac Crashes.... for the last two days I upon power up I have experienced the "White screen of death" on my 2008 Mac Pro 2.8.

for the last several days I have experienced the dreaded wite screen of death upon power up of my 2008 Mac Pro 2.8,

Screen will hang white - no apple logo - when I hit the power button resart - the mac power light does not go out, but "clicks" and the mac will restart.

I get the white apple logo screen and then some terminal script (about 20-25 lines) that lasts for a dew seconds - then an apple message appears telling me that my computer needs to be restarted due to an error - press a key or wat.... this will cycle continuously.

If I power down and boot in safe mode - the computer seems to start up - with a crash log.

Once I restart from safe mode - the mac seems to start fine and I am using it without issue - (of course until I power down and come back in the studio the following day...)

I am not familiar with crash logs - but here are the two most recent...
