After updating to 11.4 and OC 0.7.0, i'm still not seeing any SS ports when attempting to map USB3.0. This is a 300 series board, would that make a difference? Thanks for your patience sir.

Will update to 11.3, thanks so much

Great tutorial! After I map USB2 and reboot, I'm not showing any SS ports. What am I missing? Thanks for your patience. Just to note that I'm running 11.0.1 and Opencore 0.7.0.

Thanks for your patience..Presently none of my USB 3 ports are recognized by USB 3 external drives. Any advise would be most appreciated. Thanks again.

It shall be. Thank you sir!

Thank you Maldon! Would you recommend iMac 19,1 or leave it as default MacPro 7,1? Much Appreciated.

Greetings Maldon, using your Coffee Lake EFI (OC), the system has completed installation successfully. Any assistance in DSDT patching would be most appreciated. Thank you very much! Gigabyte Z390 Aorus Ultra Intel i9-9900k Radeon RX480 Big Sur 11.0.1 OC 0.7.0 Send me Bigs-Mac-Pro.zip

Good day Maldon. Dramatic improvement with Catalina 10.15.7. Minimal Graphics issues and performance is greatly improved. Would I benefit in updating OC and Kexts? Once again, thank you for all of your expertise sir. Send me Catalina061121s-iMac.zip

Thanks for your patience Maldon. Small improvement with performance, but still not up to par. Audio is not working, does not show option other than my monitor HDMI output. Would you suggest Catalina instead, or more adjustments? Much Appreciated. Send me Bigs-iMac-Pro.zip

Same results with this EFI. Behaviour has not changed. Big Sur 11.0.1 OC REL-071-2021-06-10 Thanks Maldon.

Thanks very much Maldon. System hasn't changed it's behaviour. Green "sparkles" in display with graphic glitches. Still very laggy in performance. Can't seem to get audio active either. Thanks for your patience. EFI.zip

Greetings Maldon, Installation was successful using your Haswell EFI, however performance is not as good as I know it could be and graphics are glitchy. I've likely set the wrong Framebuffer settings for HD4400. Any assistance in DSDT patching would be most appreciated. Thank you very much sir!

Thank you sir, that adjustment plus restoring power defaults did the trick. Much appreciated Maldon!

Greetings Maldon.. After updating to Big Sur 11.3, and updating OpenCore/kexts to most recent, system shuts off the display but does not power off. Any thoughts? Thank you very much. EFI.zip

Much appreciated Maldon. Thank you sir!

Greetings Maldon! Using your appropriate Coffee Lake OC EFI, system boots successfully after Big Sur installation. Any assistance in further DSDT patching would be most appreciated. Thank you so much! Z390 Aorus Pro WIFI i7-8700k Radeon RX Vega 56 Big Sur 11.0.1 Opencore Send me Bigs-Mac-Pro.zip

Maldon, thank you for your patience. I figured out how to get this machine booting with OC using the boot install command on the installer drive. I've gone back to using the initial EFI in this post. I'm still booting to a black screen with the display staying on. I've tried DP, DVI and HDMI. I've also tried with -igfxvesa. Any thoughts? Thanks again.

Maldon, I've tried your Clover (Nehalem) EFI w/ Big Sur. Verbose completes to a black screen, however my monitor stays on. I have tried -igfxvesa, with the same result. Thanks.

Intel 5520. Many thanks.

Greetings Maldon! It's a stretch but I've wanted to upgrade this old beast from High Sierra (Clover) to Big Sur. Am hopeful that Opencore is possible, but cannot boot with this EFI. I have created the installer via USB-SSD and am trying to boot the Z600 off of the SSD via Sata or the internal slots. Any assistance and guidance would be most appreciated. Thank you very much!

Good evening sir.. the previous DSDT allows for shutdown in slightly less time than this most recent one. Any thoughts as to how I can speed up shutdown? Thank you!

Thank you very much, Maldon! System runs great.

Maldon, seems to have worked itself out after resetting nvram. Any assistance in DSDT patching would be most appreciated. Thank you so much! Send me Bigs-iMac-Pro.zip

Greetings Maldon! Attempting to upgrade with a fresh install of Big Sur. Implemented your Haswell EFI and managed to complete USB installation, however upon booting to the HD via USB, I am unsuccessful. Any assistance with this issue would be most appreciated.

Same behaviour, but does not shut off for over 1 minute. Thanks for your patience.
