Ever since the 10.11 update, I couldn’t force a restart into my Windows Boot Camp partition on my Mac from the terminal, I would get an error message “Could Not Set Boot Device Property: 0xe00002bc”.
After a bunch of riggamaroll and dicking around with the USB keyboard not being detected for freaking ever, I was finally able to get booted into recovery mode. In the past, I have been able to hold the “Alt” key to select a boot device from the boot menu, but for some reason it wasn’t working any more on my Windows keyboard. I never could get the USB keyboard to show up until I was fully booted up into the OS, so eventually I swapped it out for a name brand keyboard and then it worked.
I found the answer to this problem here. Apparently they have now implemented some sort of “System Integrity Protection” which is causing the problem. The fix is to simply boot into the Mac OS recovery mode, open up a terminal, and run the following command:
csrutil disable
