The RX460 works normally after entering the system, but opening the emulator will cause the system to black out and the window to draw incorrectly. Restarting again will result in a black screen upon entering, so we still need to wait for the WhateverGreen driver update

The same thing happens to me on the RX570, I log in but the second the monitor goes black, the RX560 in OLD: it doesn't work for me with imacpro1.1

Download the version of the kext that is now available and that's it, but for example on the OLD: Radeon RX560 it doesn't work correctly, but after a while it runs out of monitor and stops working, but we're on the right track.

Well...all the kexts should be already up to date. So...unless there is an even newer version somewhere, I think those are already ok. Can you point me to the place where you got the updated ones?

Bueno... todos los kexts ya deberían estar actualizados. Así que... a menos que haya una versión aún más reciente, creo que ya están bien. ¿Podrías indicarme dónde conseguiste las versiones actualizadas?

Use kexts for tahoe, no need for beta bootarg

There is really no need to generate a new USBPorts.kext via USBMap/tree/tahoe-test. The only difference between the new and the old kext is in the two settings lines in info.plist for each port. This can be easily done manually.

old:

  

new:

 

 

 

confirm, its works.. nice

Yep, I tried those too. Unfortunately it didn't make a difference.

Hello I reuploaded it 😉 

[surenmunoo]

Gonna retire again for the night but got much further then last night. I now get to the Language screen but have no usb so cannot proceed further. After verifying the SSDT.UIAC works in Sequoia it does not recognise usb ports at that loading screen so I am still in the bush. Looks like I will have to give up on this Tahoe on my Hack. Not working on Z890 nor the Z790. Thanks @Cyberdevs for the help you provided to get me that far.

You should have tried other ports during language/welcome/login screen

@chris1111 Hi chriss.

 

I opened my system with macos 26 compatible OC files that have been released recently. including VoodooI2C kexts that previously locked the system is installed. But I couldn't load the RtWlanU and RtWlanU1827 kexts required for me to use the Asus USB wifi stick. Does anyone have an idea about the reason for this?

I also gave up yesterday. After 3 hours of trying, I haven't been able to get it to work on the only computer I have available for testing. Tahoe breaks everything. In the end, I opted to use only USB 2.0, and it boots right up to the installation screen and hangs. The 6650xt won't boot at all, not with NootRX, nor with the SSDT, which works perfectly on the Sequoia. And I also think it doesn't like my Kingston NVMe, a total disaster, haha.

 

I have more Windows computers, and I can test them today. If anyone has an EFI that works on an Asus X870F gaming and a 9600x, I'd be very grateful if you could send it to me so I can try Tahoe.

Thanks.

I have a 6750xt here and nothing... I've been banging my head against the wall for two days...

I managed to do it on the 9600x, I'm missing the Intel i226v, which seems impossible to get working with an AMD motherboard. It works perfectly on the Intel motherboards.

 

If you're using the RX6750XT, you can't use NootRX for the installation and initial configuration; you'll never get to the end. I used it at the beginning, and until I disabled it, it never finished installing... at least on my computer.

 

This afternoon, I might try again with the B450 and the Ryzen 1600AF, now that I'm a little more familiar with this new system.

No problems with RX560 and RX570 using Whatevergreen 1.7
 

Remember that the first Mac Pro 2019 was equipped with Radeon Pro 580X

Can you share your config.plist for us to enable RX-5x0 at TaHoe ?

You're welcome.

I believe if you map your USB ports correctly it will work, I mapped my ports while using Monterey and used the same SSDT-UIAC on Tahoe.

Not that i know of.  It will just work as long you setup port mapping correctly

Thank you for the reply. 

I successfully completed my USB Mapping and when I checked again, I realized that the relevant kexts were still not installed. @chris1111

My Bluetooth works perfectly. Now it's wifi turn we're waiting for a wifi patch from the developers for this. I would like to thank all those who supported. Broadcom BCM4350

As for the trackpad, its a race issue between the Voodoo and Apple's own driver 🤔. We have to wait till the 2nd release

My USB port mapping is now sorted after downloading the correct tree, as the previous download was the master and not tahoe-test 😝. I am patiently waiting for the updated Voodoo for my trackpad 🫡

My trackpad is now working 😜 and now is time to thoroughly sip Teaho 😂

There's no sound output from the music app, is this happening to only myself or what?

Updated the Download Full Installer repo with initial support for macOS Tahoe.
Note that Tahoe beta is listed in the PublicSeed catalog.
Package name in the catalog list doesn't include the word Tahoe but it is visible in the ToolTip, and the build number is correct.

 

Spoiler

Regarding the name Tahoe in the package, I've noticed that this is the way Apple is releaseing this beta.

I solved the problem with the clean installation of Mac OS 26 Tahoe by reformatting the NVMe SSD Samsung EVO 980. After that, the clean installation worked perfectly.

 

What about a new OCLP for my iMac, which is 2013? Is it possible to install it on this iMac or is the team still working on a new OCLP patcher?

"Well we have a winner"

After I finished installing with the integrated graphics card,

I plugged in the RX 580 and continued so I could see.

I don't know what Apple is thinking but this time they made it really hard..

But this time too I am sure that the team (insanely) here and opencore team will give us the victory. 😇😘
