Found the reason for crash on bootup. I added a NULL check in the getMultipleDisplays my suspicion is that getMatchingServices() reutrns NULL on boot up.

     OSDictionary* dict = OSDictionary::withCapacity(1);
     dict->setObject(kIOProviderClassKey, OSString::withCStringNoCopy("IODisplayConnect"));
     OSIterator* ioDisplayConnectIterator = getMatchingServices(dict);
+ if (ioDisplayConnectIterator == NULL) {
+ return false;
+ }
     unsigned int displayCount = 0;
     OSObject* obj;
