Hi, friends i really have an important question which revolves about the iMac and Thunderbolt eGPU(external Graphics Card). So far all i know is that the iMac does support External graphics card but when it comes to its very own Mac OSX, it does not support but when boot camping windows it does support. But my concern is that, is it really true that mac osx does not support egpu but windows does(by boot camp), and is it also true that imac does support External gpu, i was asking because all i watched videos in youtube about thunderbolt egpu are with MacBook Pro but not with iMac. Please a guide and an accurate answer would be very helpful. thanks in advance..!!!
