So what I did was connect another Display in my oboard GPU VGA Input, and when I boot using this, the pre-OS stuff appear in that display, and after the OS is loaded the image automatcly jumps to my main display using my main GPU (R9 290X). I got this help in other forum, so let me help you with that.Īll you need to do is go in the BIOS iGPU settings and select your onboard graphics as primary, but if you do this you will get no pre-OS graphic. Hey guys, there is a simple way to boot using R9 290 or R9 290X.
I just installed macOS Sierra in my pc and I have a i7-4790k and r9 290x, but when I boot the pc to do the post installation stuff, i just got a black screen, and appear in the display "no HDMI signal", can you help me to at least boot the OS to try something?Īlso, R9 290X will not be compatible with Sierra, or it will be a fix soon? 10.12 Safe mode loads just fine oddly enough, though obviously that's not a solution. This happens regardless of whether I use displayport or DVI.Ĭard works fine in windows and 10.11. The machine is somewhat properly booted during this as I can ssh in and run terminal commands, but windowserver is stuck at 100% cpu usage while this white screen is up, and I obviously can't get past it. I used to see this in 10.11 too, but it would only appear for a split second before dumping me to the login screen. The machine starts the boot process fine initially (apple logo, progress bar), then when the progress bar reaches the end, I see a white screen with some minor video artifacts randomly appearing (sort of like random flickering black streaks) instead of what should be the login screen. I have a 290x that was working in 10.11 with no fb patches or injection and am having smiilar problems in 10.12.
