MacPro (late 2013) freezes on startup then shuts down

Dear Community,


my MacPro Late 2013 suddenly has an error!


3,7 GHz Quad-Core 10 MB L3-Cache

12 GB (3 x 4 GB) DDR ECC 1866 MHz

1 TB PCI-e- Flash

2 AMD FirePro D700 GPUs each 6 GB GDDR VRAM


I just can't get my Apple Mac Pro to work again, this is what usually happens when I start the MacPro. It just freezes there and then shuts down after a few seconds

it says that everything is fine

Apple diagnostics tend to say "No Fault Found". That is NOT an indication everything is fine, it is just what it says -- the test did not find anything (maybe because the test is not as strong as it should be).


The green lines on the screen in your original post are a view into the memory on the display card. They indicate that memory is scrambled up garbage. At a minimum, they should be a single uniform color.


I think you have a Hardware Problem, and should take your Mac in for service. Be sure to make an appointment, else you will be turned away and scheduled for later.
