Are there any hardcore programmers? void *CGDisplayBaseAddress(CGDirectDisplayID display) is deprecated since Snow Leo and may vanish completely in the future. No replacement from Apple. I need it. Same thing with CGDisplayBitsPerPixel() and CGDisplayBytesPerRow(). Is it possible to get it another way (IOKit). I don't have any experince with kernel services. -IOFBGetFramebufferOffsetForAperture? -IOFBGetFramebufferInformationForAperture? I can't get these working properly.
