murvold Posted March 26, 2018 Share Posted March 26, 2018 (edited) GA-X79-UP4; i7 3820; 32gb RAM; Nvidia 970 Trying to upgrade my working Sierra 10.12.6 to High Sierra 10.13.3. My previous hack is based on Rampagedevs x79.dmg. I've tried several combinations of dropping MATS/BGRT table from ACPI fixes which is recommended for Gigabyte boards and also checked the "fix headers" option there. I've included my zipped Clover folder from EFI. Each try ends with Mach Reboot. Any help appreciated and thank you in advance.
