It > might be the frame buffer corruption that Ed Maste was mentioning. I purchased a new MacBook Air yesterday (model identifier MacBookAir6,2). UEFI boot and vt(4) worked correctly. (My image included Rafael's patch; I haven't tried a boot without.) I also committed a change to display the framebuffer parameters (address, dimensions, etc.) on boot, in order to help identify the source of this issue. If you have a moment can you build a new USB stick image and give it a try? -Ed
