Hey Mac Pro users, We had to take in a nMP due to issues with failing to boot into the OS even after a restore. Long story short, it is currently at an Authorized Service Center waiting for a replacement GPU A d500 card. Well we've been told both by Apple and the service center that there is a wait on this replacement part. According to Apple rep I spoke to, there is more demand for this replacement part than there is supply. Have other late gen Mac Pro users with d500 GPUs experienced problems? We have two other identical machines that have yet to incur problems, but the shortage of replacement parts has me fearing this will happen again with others.
