rotalume Posted November 17, 2018 Share Posted November 17, 2018 Mainboard : Gigabyte X58A-UD3R(No UEFI, legacy boot only) Graphic Card: Gigabyte Vega 56 GAMING OC 8G I have an issue when I upgrade my Yosemite build to High Sierra at login screen as attached. I had successfully installed Yosemite (Cameron) and El Capitan (Clover) in different disk with R9 270X.Now I upgrade my R9 270X to Vega 56 and upgrade the Yosemite to High Sierra in order to have the driver support for VEGA series. I installed Clover from official website to override Cameron and rename Extra folder, solved the issue for ICH10R booting then installed High Sierra 10.13.6 which I downloaded long time ago. Everything works fine except the screen. The screen looks good at BIOS and Clover but turn to the issue when booting into login screen. I can still use ssh or remote desktop to access the machine, check it determined my vega 56, play youtube or run benchmark with the scores that should already enabled hardware acceleration. But I don't know how to fix this screen issue. I have checked a similar issue on tmac about CSMVideo but Iam not using UEFI so I cannot solve it that way. Tried to change smbios to iMacPro 18.1 or with vega5kfix or kext to patch from Pike turned to black screen and cannot be connected by Remote Desktop Tried combinations of InjectATI and Radeon DeInit no luck Any suggestion is welcome.

Slice Posted November 22, 2018 Share Posted November 22, 2018 Reinstall macOS. It looks like a bug with desktop size. Link to comment Share on other sites More sharing options...
rotalume Posted November 22, 2018 Author Share Posted November 22, 2018 Thanks, finally I got someone replied this. But I am afraid that might be caused by the driver or clover settings. Because I also made a usb bootdisk in order to keep the High Sierra for another installation. I tried to boot from the disk and had the same situation. I also got another 1070 Ti card and it works fine with the this installation just different parameters in clover with the web driver installed. It will still be great to get the VEGA works because I prefer the color whatever in desktop or in gaming. Link to comment Share on other sites More sharing options...
rotalume Posted December 4, 2018 Author Share Posted December 4, 2018 Sorry to bump this up. In short I gave up my vega 56 as 1070 Ti works very well with webdriver. Hope someday I can get AMD back. Link to comment Share on other sites More sharing options...
Slice Posted December 14, 2018 Share Posted December 14, 2018 There are observations that Radeon card 7xxx and up (as your Vega) will not work in HighSierra on chipsets pre-SandyBridge. Pity. You have to stay on 10.12.6 or change card to supported one. Link to comment Share on other sites More sharing options...

I actually did try it on 10.12.6 with different SSD installations as there were some incompatibilities in Wine and some existing applications but still the same issue.
