My Mac Pro will not start up. I have done everything I have read to do online and it still stops before finishing startup. Even with a start up disc!
Any help?
PS: I have lots of other photos showing things I have tried if anyone is interested.

- Once the tool finishes running, your system should now run without the dedicated graphics, and should work completely normally.
the program's name is:
MacBook Pro dGPU disabler.app

What is the last picture showing on the screen before it turns blue? .

I purchased a Zip drive to start up from and I have the exact same results as with the DVD. It starts to load and then goes to the blue screen as noted in my first photo.
Any help?
Interesting..
No I don't use an external display or edit videos.
Yes I'd like to try the work-arounds you might be able to send.
Thanks!
