pastrychef's Asus ROG Strix Z370-G Gaming (WI-FI AC) build w/ i9-9900K + AMD 6600 XT

What exactly did you change? The original 0.6.6 from you works smoothly so far, so should I still change to the new one?

Yes, change to the new one. The first one had old version of the OpenCore.efi.

Yes, change to the new one. The first one had old version of the OpenCore.efi.

So can I just change the OpenCore.efi ? I have some others changes and it would be easier to just overwrite the OpenCore.efi

After running Clover for a long time I just bit the bullet and switched to Opencore. Today I downloaded your premade "EFI OpenCore 0.6.6 Z370G" zip folder, put in my particular info and booted up. Seems to run 100% OOTB. Startup disk easily selected in mac prefs. The only thing that is not working is the older USB 2.0 port(s.) This port was working fine in Clover bootloader. Under Opencore these USB1112 and USB1314 connections on the Mobo seem entirely deactivated. Plug a drive or device in and (nothing.) This is not a deal killer but -- can it be made to work? I see a lot of USB port-mapping talk about Opencore. What is necessary?

Yes, those internal USB headers are disabled due to the 15 port limit. You can enable them yourself using the following guide:

Important Update: June 2023 From Big Sur 11.3 on the built-in OpenCore XhciPortLimit quirk no-longer worked as described. This became a known "bug", though in reality it was Apple changing their internal code, making a simple "peek and poke" to keep it operating, a difficult task. However, with...

Oooof. Not exactly simple. Cumbersome but I will give it a try. Thanks for pointing me in the right direction.

And now -- reporting some slightly strange behavior in Opencore 0.6.6 -- and a fix for now.

I used the "EFI OpenCore 0.6.6 Z370G" folder you made and set up a system with two SSD drives (so I can boot from either) with identical EFI folders with the config.plist modified to include my serial, etc.

For a day, this seemed to work fine. Then randomly, suddenly the system stopped booting and froze on a black screen with the error messages:

OCSB: No Suitable Signature - Security violation
OCB: Loadimage failed - security violation

(So thanks Apple but I'm not all that worried about security at home at my desk.)

My fix was to go into my plist and change the secure boot model from "default" to disabled.
Default identifies the system as an iMacPro1,1. (Which is true, but maybe not enough.)

I got the solution from the Dortania guide section on Stuck on OCB: LoadImage failed - Security Violation.

<key>SecureBootModel</key>
<string>Disabled</string>

I'm not sure why my system had this OCB / OCSB issue and yours did not. The major difference may be that I am still running Mojave 10.14.6 because I have some older 32-bit software I use.

While "disabled" seems to work now, I see that I might also try the value "j137." From Dortania:

Type: plist string
Failsafe: Default
Description: Apple Secure Boot hardware model.
Sets Apple Secure Boot hardware model and policy. Specifying this value defines which operating systems will be bootable. Operating systems shipped before the specified model was released will not boot. Valid values:

• Default — Recent available model, currently set to j137.
• Disabled — No model, Secure Boot will be disabled.
• j137 — iMacPro1,1 (December 2017). Minimum macOS 10.13.2 (17C2111)
• j680 — MacBookPro15,1 (July 2018). Minimum macOS 10.13.6 (17G2112)
• j132 — MacBookPro15,2 (July 2018). Minimum macOS 10.13.6 (17G2112)
• j174 — Macmini8,1 (October 2018). Minimum macOS 10.14 (18A2063)
• j140k — MacBookAir8,1 (October 2018). Minimum macOS 10.14.1 (18B2084)
• j780 — MacBookPro15,3 (May 2019). Minimum macOS 10.14.5 (18F132)
• j213 — MacBookPro15,4 (July 2019). Minimum macOS 10.14.5 (18F2058)
• j140a — MacBookAir8,2 (July 2019). Minimum macOS 10.14.5 (18F2058)
• j152f — MacBookPro16,1 (November 2019). Minimum macOS 10.15.1 (19B2093)
• j160 — MacPro7,1 (December 2019). Minimum macOS 10.15.1 (19B88)
• j230k — MacBookAir9,1 (March 2020). Minimum macOS 10.15.3 (19D2064)
• j214k — MacBookPro16,2 (May 2020). Minimum macOS 10.15.4 (19E2269)
• j223 — MacBookPro16,3 (May 2020). Minimum macOS 10.15.4 (19E2265)
• j215 — MacBookPro16,4 (June 2020). Minimum macOS 10.15.5 (19F96)
• j185 — iMac20,1 (August 2020). Minimum macOS 10.15.6 (19G2005)
• j185f — iMac20,2 (August 2020). Minimum macOS 10.15.6 (19G2005)
• x86legacy — Macs without T2 chip and VMs. Minimum macOS 11.0.1 (20B29)

Apple Secure Boot appeared in macOS 10.13 on models with T2 chips. Since PlatformInfo and SecureBootModel are independent, Apple Secure Boot can be used with any SMBIOS with and without T2. Setting SecureBootModel to any valid value but Disabled is equivalent to Medium Security of Apple Secure Boot. The ApECID value must also be specified to achieve Full Security. Check ForceSecureBootScheme when using Apple Secure Boot on a virtual machine.

macOS 11.2.1 Update, took ~17 minutes, rebooted three times.
OpenCore 0.6.6

 

[pastrychef]

Took about 30 minutes and system auto rebooted three times. I'm on OpenCore 0.6.6.

I updated to 11.2.1 from 10.15.7 today. Still early but seems to run fine. Getting 1300/7300 (+/- 50 points) in Geekbench 5 and around 60K in Metal and Open CL . This is a 3 year old build regarding HW, so these numbers are quite satisfactory to me. Especially if I compare to newer systems. I might get marginally better performance going with a Ryzen gen. 3 and an insanely priced latest gen graphics card, but I only use Capture One and FCP (occasionally), so a HW upgrade seems overkill to me. I could probably get a really nice camera or 2-3 lenses for less than an upgrade would cost. Anyway. I just wanted to thank @pastrychef for all the help and troubleshooting over the years. I really appreciate it. THANK YOU!
