Obrigado. Excelente trabalho. Your DSDT works well and has made for a clean system with minimal .efi and .kext files. I started with your model EFI and have stripped unneeded files and Clover settings. Added a personal .kext to reduce USB ports to only the used ones and eliminated the PMHeart patch/USBInjectAll. Overall, now a fully functioning, stable system that should require no changes with OS updates. And, as a bonus, the system boots 25% faster. Thanks, again.

I’ve attached a Send Me file for my ASUS Prime Z270M Plus with Radion RX260 graphics and hope you can create a DSDT that will make for a cleaner, minimal kext installation. I’ve just upgraded to Catalina after using High Sierra successfully for two years. The Catalina boot has a lot more warnings/errors on booting which concern me but haven't caused any noticeable issues. One nagging issue is that USB power doesn’t permit charging an iPad. Your assistance is greatly appreciated. Jim Send me Jims-iMac.zip
