enlaid Posted January 19, 2020 Share Posted January 19, 2020 (edited) Hello, I found SSDT that run native NVRAM on Z390 motherboards. SSDT contains PPMC and PMCR devices from iMac19,1. Please test Before use remove EmuVariableUefi and Clover RC scripts!

HmO Posted January 19, 2020 Share Posted January 19, 2020 (edited) What is it? Edited January 20, 2020 by HmO 1 Link to comment Share on other sites More sharing options...
enlaid Posted January 19, 2020 Author Share Posted January 19, 2020 (edited) Use only SSDT.PM.aml (from attachment). Tested on Gigabyte Z390 Gaming X, Gigabyte Z390M Gaming and Asus Z390 Prime A with OsxAptioDrv3 and AptioMemoryFix in Clover - native NVRAM works fine, reboot and shutdown without KP.
