stretched

How to boot my Hackintosh like a real macbook pro or air retina? Please if anyone knows help!!!!!!!! With the black screen and white apple logo and also my apple boot logo is stretched searched a lot but did not find any solution.

Hey guys! I'm here to teach how get your grey Apple Boot Screen in BLACK! So, those guys who have a Graphics Card that don't have Vesa options to boot in the right resolution... You can make all the thing black with an Apple Logo in the center. It looks awesome! I spend like a month...
