Mac notebooks are known for faulty GPUs. Dating back to 2008. First thing you should do is check the Apple forums for posts about faulty GPUs on the 2015 models and see if there is a recall or replacement program of some type.
Apple supplies all the drivers for all the hardware in a Mac. The disabling of the discrete GPU should not hinder you in processing your RAW files in ACR. In fact it might make it slightly faster with the GPU option disabled (It does on my Windows 7 system) and I bet the GPU is also disabled in LR.
The other error is because there is an option set in the Mac OS X security option to not allow anything to run on your Mac unless it came from the Mac App store or a registered developer. Just turn that option off.
I've tried disabling the use of graphics processors in the camera raw preference but still no success. I have searched the apple forums (and google), while there are posts about faulty GPU's most deal with actual display errors. Can't find anything about raw files not opening and crashing photoshop.
So it turns out something was probably wrong with the install on my MBPr. I went to Apple and did a clean install and everything seems to be working fine now.
