Hi, this might be a really dumb question but I wanted to know if there were any potential advantages/drawbacks to disabling the internal graphics HD 4600 that comes with my i7-4790k.

I have a GTX 960 as my primary card but I read somewhere that Final Cut Pro might prioritize using the internal card versus the card plugged into the PCIe slot. Not sure if iMovie might do the same thing (or any other mac software for that matter).

Would disabling the internal card in my motherboard BIOS cause any issues with the system?
 
Disabling the IGP won't cause any problems.
 
Try "Activity Monitor" of your system utilities to see the GPU usage, maybe your right, but without internal GPU it may not run and will not switch to plugged in GPU.
You can disable the internal GPU in the BIOS. Press F11 or what is shown on the screen by startup to get in the BIOS ;)
