Macbook retina display wont let me connect to the tv. All I see on the tv is black with a white mous
Recently I bought my macbook with retina display and when I plugged it into the television with using the HDMi cord it worked perfectly fine with the image on the television. But now I when I plug it in to the television it comes up with a black screen and a white mouse. Before this incident I was mucking up with the setting of the mac book and I dont know what I did wrong. Can someone tell me how to fix this ?
