I am using MacPro6,1 on Monterey Can u identify which ports are not detected ? Well, they're all working with USB3 device except F_USB1 Port 5&6 and F_USB2 Port 8 ( the upper one on the picture ) and same as previous with USB2 device plus XHC1 port4 and one of the XHC1 port 1 or 2 (seems to be 2 but unsure though, because I cannot check properly the wiring ) My SMBIOS def is iMac 13,2.

alberto21 Posted October 19, 2023 Share Posted October 19, 2023 I see, it could have been the reason, but in my case, I still have some USB3.0 drives who behave as usb2 in F_USB3 and only in one of the F_USB2 and are not recognised at all as USB2.0 in F_USB1. Digging into ACPI table topic it look likes macOS doesn’t deal like it use too with port names. So it needs to be remapped, so in order to, I’m trying to use this tool: https://github.com/corpnewt/USBMap. It should be able to map automatically and write a kept to load with OC at boot but right now, on execution of the command related to USBmap, I’m still blocked on a message stating that « XHC1@14 @ _SB.PCI0.XHC1 (Needs Rename) » I can’t figure out yet where to rename it.

alberto21 Posted October 29, 2023 Share Posted October 29, 2023 A Bit Off Topic BUT, I'm Working At Putting OC Into Bios, Like Ozmosis Would anybody like to give me a hand Hi, In my opinion, since you would have up to 32MB in the Motherboard ROM, I think you could run short of space while trying to fit everything inside the rom. Also as Opencore is evolving, you might have to externalise some kext and else files out of the ROM because of space laking. Since an EFI size is 10 times bigger, may I suggest to just keep a USB stick connected internally with Opencore on it ? I can see some benefits to this, to update it's much easier: no need to reflash the bios and reset all the mobo settings each time again. You will avoid headaches if you mess up while trying to squeeze everything inside the rom binary file. If your approach is to keep the HDD as vanilla as possible, the EFI partition will be some how attached to your motherboard and not to your HDD, so it remains bootable on a legit Mac. What do you think ?

alberto21 Posted November 14, 2023 Share Posted November 14, 2023 That would be in the ACPI Section of config.plist Thanks for the input.In the end, the ACPI approach wasn't the best and easiest, the kext approach turned out to be much better and simpler. There is this utility called usbtoolbox which allows to map USB ports under Windows, it creates a custom fit kext describing to MacOS how to detect USB ports. As a result, all my USB ports work. The 2.0 as they suppose to and the 3.0 with their 2.0 companion. It’s a good stuff to respect the 15 port limit to avoid extra tweaks.Regarding your switch to Monterey, as I’m just scratching the surface of the subject, have you added anything other than the macpro 6.1 definition to SMBIOS ? Would you be willing to share your EFI?Thanks Link to comment https://www.insanelymac.com/forum/topic/343145-guide-z77mx-quo-aos-migrating-from-ozmosis-to-opencore/page/10/#findComment-2813516 Share on other sites More sharing options...
David97498 Posted April 28, 2024 Share Posted April 28, 2024 (edited) I have been using the method of installing macOS set out in this forum with the Z77MXQUOAOS.H4O.OC.ROM and OpenCore on my Z77MX-QUO-AOS for several years. The specification of my set up is in my signature below… I used the packages from IronMan to update through each OpenCore version up to 0.8.8 when that version was posted. Since then I have been using OCAT successfully to update OpenCore after each update was released. I have saved the updated EFI on a micro USB. I have always kept a backup EFI on another USB with a further copy on my iCloud drive. Each update this way has been successful. I have two OS, Mojave and Monterey each on a separate SSD with a bootable backup drive. I updated to using OCAT to OC 0.9.9 and everything on both macOS was working as it should. After a couple of days of testing. However a few days later it stopped booting successfully. I tried the backup EFI I inserted into the USB port and got the same list of errors with both EFIs. I also tried reinstalling the Z77MXQUOAOS.H4O.OC.ROM I am having no success and don’t know what to try next…. It’s also been so long since I originally set up OC on my Z77MX-QUO-AOS I am at a loss as to finding a solution. (btw - both the SSDs will boot on my macPro 5,1) Help please.

ThAnEb Posted June 29, 2025 Share Posted June 29, 2025 (edited) Hi everyone, For user seeking for update for their still working Quo board, I am happy to share that you can use OCAuxiliaryTools to update the 0.8.8 kit to latest OC (for now it's the 1.0.4). The app will also correct issue in the plist. As sugggested on their github, use the guide here to easily update: https://github.com/5T33Z0/OC-Little-Translated/tree/main On my side i also used it to update the smbios to iMacPro1,1 which, according to what GPT and Claude confirmed (by scrapping all forums much more faster than i could) should improve the support for my NAVI gpu (RX5600XT).

IronManJFF Posted July 25, 2025 Author Share Posted July 25, 2025 Yes, OCAT is the way to go. Link to comment https://www.insanelymac.com/forum/topic/343145-guide-z77mx-quo-aos-migrating-from-ozmosis-to-opencore/page/10/#findComment-2837892 Share on other sites More sharing options...
David97498 Posted August 6, 2025 Share Posted August 6, 2025 I have been using OCAT for several years now and recently updated to Opencore 1.0.5 After reading ThAnE's post of June 29th i tried installing Sequoia 15.6 but after several reboots during the install process (as expected) it went into a boot loop with the progress bar appearing only for a split second before going back to the boot selector repeating ad infinitem. I'd welcome any suggestions.

IronManJFF Posted August 7, 2025 Author Share Posted August 7, 2025 Don’t know if you have a special need for Sequoia but I stopped at Monterey .

David97498 Posted August 7, 2025 Share Posted August 7, 2025 (edited) I, too, had stopped at Monterey. I don't need to install Sequoia - I'd like it to show it's possible, if indeed it is? This config.plist with OpenCore 1.0.5 will let me start and almost install it, but at the last reboot, it gets to the Apple Logo and the progress bar appears as I mentioned for a split second - it's indicating that there is still some progress to be made before the 'crash'. I'll attach the config.plist and a screenshot of the kext folder. I had hoped someone on this forum with more knowledge than I and adept at solving technical issues with perhaps knowledge of the 'inner workings' of OCLP could point me in the right direction. (BTW, after reading that bootloops with an OpenCore installation of Sequoia could be fixed by adding AMFIPass.kext (v. 1.4.1) and editing the config.plist file appropriately. I added it manually to the EFI, but the Sequoia installer would not boot, and neither the Monterey nor the Mojave SSDs would boot.) I removed it, and I am back to the boot looping towards the end of the installation process. Thanks in advance David.
