VoodooHDA is a good solution. However, I have Ventura, Sequoia and Tahoe with the same EFI. If I remove AppleALC.kext I will have to install VoodooHDA on all of them. So I looked for another solution.😂

Try using Min/Max kernel settings for AppleALC.kext.

If you limit the the Max setting to 24.9.9 it won't load in Tahoe and you can use VoodooHDA just for Tahoe.

Try disabling DisableIoMapper in Kernel -> Quirks, on my Z690 rig when I enable DisableIoMapper it shows the same behavior.

Thanks

I just lose ethernet when I do that. Got the 1225-V. I'll try to find another way to get that working.

Hey guys!

 

I was just wondering (and, in my case, it is related to Tahoe, but it's also more of a general question): if someone would want to learn how to do device properties patching the right way, where would they go? Is there a tutorial on that somewhere? More like a book maybe? :)) I tried to search the forum for something like that, but I couldn't find it.

 

I know it will be different stuff, different patches, depending on what you're trying to patch. But still, I'm more interested in the general workflow. I mean, what kind of information do you need to add? Where would you get that information? For example, do I still need to patch device properties for my RX 580 if I'm using WEG? Do they conflict with each other? Can I achieve full functionality only with device properties? When should someone patch device properties, and why? Is it just "cosmetic"? Or is it also functional? (My guess is that it's probably both.) What are the best practices when doing something like this? And stuff like that.

 

Do we already have a topic dedicated to this? If so, can someone please point me to it? Or is there another resource online I can use to learn more about it?

If the system is stable with DisableIoMapper disabled, that's a good idea to find another way to enable the ethernet, in my case I have to use two SSDTs for my 10 Gbps ethernet to work. (SSDT-Aquantia-AQC113C.aml and DTPG.aml), but I'm not sure what options are available for your 2.5Gbps ethernet.

Thanks. For now, I solved the sound problem with the USB sound card. But I am backing up this solution. Thanks again for the information.

Hi my friend. We are at the same boat. I need said that people who have knowledge advanced not share at all. I try use my little knowledge to search for GitHub pages, another forums and using ChatGPT. This is sad 😞 but the true story for all beginners and more advanced hackintoshers. We not have a book. Need search and save for years.

I tried all the combinations that came to my mind. and with and without WhateverGreen, and NootRX and without it. I can't figure out what the problem is, I've been fighting for 3 days. maybe someone will look from the side and see what I don't see?

I downloaded the installer twice, changed the USB ports. kexit used to change Openkore, a long time ago I came across a similar error - the solution was so elementary that I forgot😀

Has the procedure for creating a flash drive with the installer changed? compared to Sequoia?

Do you mean you did run Tahoe with iMacPro1.1.  I was told it is incompatible . Would you mind to share your EFI ?

Any comment or help is appreciated on how you could run Tahow with iMacPro1.1

@ANTIKO Good day Bro,

CPU is definitely not supported by Mac.

 

Thanks, but Tahoe supports Mac Pro 7.1, there's no video core either. I will definitely study the link. In the meantime, I'll be sitting on the riverbank.

I don't know what kind of error you are getting. However, Booter/Patch is sufficient for installation with imacPro 1.1.

You don't need Skip Board ID check for MacPro7,1. Try without ctrsmt=full. I have better benchmark.

You have to use Skip Board ID check. But taking in consideration today reality is better MacPro7,1.

Just used the BOOTCAMP Assistant and partitioned my 1TB NVME from Samsung 980 Pro to 350GB (macOS Tahoe Beta 2) and 650GB to my Windows 11 25H2.

 

In my first try it not installed windows and give me an error over Windows 11 Installer, changed a bit in Bios and voila Windows 11 25H2 started the installer and I was able to install Windows without any issues...

 

Now I had both systems in dual boot with OC 1.0.5.

 

I´m installing Forza Motor Sport 7 witch has 99GB and eFootball (78GB) - Speaking from windows with you guys...

 

Nice Graphics Card everything on Ultra 4K HDR, and was smooth..

 

DS4Windows + my PS4 controller.

And my G920 Wheel with Shifter 6 gears manual.

Working Like a charm.

 

Regards,

Fernando.

Aaa little games of a few mb 🤭

I would have used WindowsInstall.app (you can find it here on ( sergeygalan ) IM ... I'm not at the PC right now)
No bootcamp needed

no need to create a bootable USB
enable in the app No Esp and it does not overwrite the OC boot, it will only place the Microsoft directory in Efi

Good day to all,

Yesterday pissed at the lack of network and my inability to make it work I decide to reinstall Tahoe, at the reboot I'm confronted with the inability of the general EFI from Olaria to boot the installer. Ater that I have used all EFI's that are laying around to try and install Tahoe, with no success.

i made and EFI from scratch and it boots the system until it arrives at this part and the installion stops.

Could anyone see the above picture and point me in the right direction.

thanks

Enable IGPU and -wegnoegpu boot-arg. HDMI to MB. BIOS first boot IGPU. After install, return all. I assume you have another MacOS installed. Do it from there. If you can boot to working MacOS with IGPU main, you can install also Tahoe.

For IGPU use this:

I just posted it for you, but the same thing was happening to me. The solution is to create an installation USB with the default IGPU active and the Radeon graphics disabled via OpenCore.

 

revpatch=sbvmm  -lilubetaall -alcbeta -wegbeta -wegnoegpu

[Anto65]

I didn't understand why you quoted 3 times hahaha anyway yes that one, thanks

Cool @chris1111 

Honestly, I've connected a sound card to the USB port, but I'm getting no sound from my laptop's internal speakers on macOS 26. And I don't have any external speakers, just Bluetooth. 😁

I used the the booter/patch as recommended by you. I then was able to boot into Sonoma as iMacPro1.1 once , but it booted Tahoe as MacPro7.1 ,  not iMacPro1.1 More interesting thing is it did not boot as iMacPro1.1 in my later attempts to Sonoma/Sequoia and Tahoe.
