Yee Posted November 9, 2017 Share Posted November 9, 2017 Hello I have trouble installing new system Sierra 10.12.6 and High Sierra 10.13.1 on my old legacy machine (old 775 socket without UEFI): Gigabyte GA-G33-m DS2R HIS HD 6570 1GB Xeon E5430 (mod from 771 to 775) disk GPT parted To this time my graphic card work flawless with old MACOS X version like Yosemite or ElCaptain. I never need injection, patch or kext to get full working resolution and acceleration. Now i can not install new system (installer patched against legacy/mbr installation) - after booting with -v option my hardware is recognized, no hangs or kernel panic, but when installer want switch to GUI i got black-gliching screen with semi black&white snow. AFAIK my graphic card is supported by Sierra/HighSierra (0x6759) - i tried many options with lilu.kext/WhatEverGreen.kext as well, without success. No matter what my monitor (HP w2216) always ended witch gliching screen. Any suggestion? Link to comment Share on other sites More sharing options...
Slice Posted November 10, 2017 Share Posted November 10, 2017 You should not have problem in Sierra but for HS you need to replace 4 kexts. For Sierra I may propose you to exclude lilu/we and take Clover 4296 with new option RadeonDeInit=YES. Inject->ATI=NO 1 Link to comment Share on other sites More sharing options...
Yee Posted November 10, 2017 Author Share Posted November 10, 2017 Thank You for help. After install Sierra 10.12.6 with my build-in card intel 3100 (VGA mode) and removed ATI card I switched to new Clover and put back ATI card. Clover 4297 with RadeonDeInit=Yes solved only partially my problem - now i can watch whole boot proces messages, GUI starts without gliches, but dark (blank) Link to comment Share on other sites More sharing options...
Yee Posted November 13, 2017 Author Share Posted November 13, 2017 High Sierra 10.13.1 on Clover 4297 + rollback kext from Sierra + lilu/whatevergreen = full resolution and acceleration Link to comment Share on other sites More sharing options...
