Is the AMD Radeon Pro WX 4100 4 GB supported?

Eu tentei o seu EFI com o mesmo SMBios 7.1 para inicializar com pendrive, mas infelizmente parado neste momento, não sei se é um problema com a minha placa sem fio, eu tenho um Broadcom BCM4360, anexe minha lista de dispositivos pci. Espero que possa ser resolvido, caso contrário, devo tentar atualizar através do Sequoia sem usar pendrive. Agradeço antecipadamente pelo seu apoio.

Could anyone take a look at this EFI and tell me why it don't boot Tahoe?

Thanks

My Lenovo T14 is fully set up, and I managed to install everything from scratch and via OTA, using my EFI below. For anyone who wants to compare, I owe the successful installation to the details of each carefully edited SSDT, with the help of many GitHub tutorials, especially regarding the Thunderbolt ports. Since this setup is quite unique and took me many months to prepare, it would be difficult to explain step by step. The EFI is available, and not everyone can reach this level—so if you're trying it on desktops, you might get good results. My Lenovo even got to the point of encrypting the NVMe, but right after boot, I disabled FileVault. 

 

Here my EFI  Works on Tahoe Beta 1 and 2 from off line installer or OTA.

Hi @MorenoAv maybe you can try use -lilubetall and deleted kexts for OCLP.

Try to install kext in the correct order, disable everything related to WiFi. Fix the errors. Maybe it will work

Not on beta 1, but it's showing on beta 2.

 

Btw, clean install of beta 2 without issues (and audio):

Which SSDTs are responsible for thunderbolt, as I never got mine to work properly especially hot patch and see if I can do some proper comparison 😆

... Important advice for all affected users: Just disable WEG during the Update or clean install of Tahoe Beta 1 or 2 and enable it again subsequently. With SMBIOS MacPro.7.1, WEG is in principle not deemed necessary. 

@KGP-iMacPro
Tks. Your tip worked for my setup.
Now we wait for the audio and OCLP.

HP Z840 with Sapphire RX 580XT.

 

clean install from USB doesn't work for me, it stuck at 16%

 

installed from Sequoia, it finished installation and boot up. I still have problem with wireless Logitech mouse and no wifi. Heliport doesn't work because I cannot got itlwm.kext to run.

anyone got heliport working?

Thanks

Beta 2 installed. Played around with EFI until it booted up. I upgraded the beta 2 install from the Software Update in System Settings.

Could someone shed some light on VoodooHDA matter, please?

I'm using version 3.0.2, put it in the kext folder in OC and config too, but it doesn't seem to work.

Is there something else I need to do, like layout-id in device properties?

Thanks!

Morning all, I made a new efi folder using Opcore simplify inside windows 10

rebooted to macOS sequoia.

I then removed all kexts barring the bare minimum ( lilu virtualsmc, Ethernet and whatevergreen  and to my surprise the installer booted and the installation completed, however on arriving on the desktop and opening system settings I’ve no Ethernet, had a look at system profiler and the kext for artheros killer nic e2201 has not loaded.

I’ve checked and checked again and the config.plist the kext should load but doesn’t 

anyone have any ideas I’m at a loss

The attached EFI Folder boots Sonoma, Sequoia and now Tahoe fluidly.

This Folder was initially successfully built for a clean install for the first Tahoe Beta (after much fafffing around as Apple removed support for the RX4 and 5xxx Cards.

 

Consequently the EFI Folder was built with the UHD 630 Graphics taking the RX580 offline which was successfull.

As reported, in the second released Tahoe Beta, Apple included the returned use of the RX Cards, so all that was needed was to reverse all UHD 630 Settings both in the BIOS and EFI Folder which worked out quite well.

 

Now here is where it all gets weird, the same converted EFI Folder (back to RX580 use) is near enough impossible to build an Installation USB drive for Beta 2.

I defy anyone to tell/show me different, yes they have been a few claims of successful fresh builds with RX66xx Cards, as I don't own one, I cannot refute the claims but my own experience is with RX5xx.

 

I have tried every which way, plus suggestions here in the open Forum and P/M which I am grateful for but none came to successful results.

In conclusion the only way is to fresh install Beta 1 and then Update to Beta 2 with an RX5xx Card. I will see what change the next release brings before I test again.

For a clean install try this. Before installing disable integrated graphics in bios.

I think Apple is playing with everyone in my country. When they want to do something and you're not ready, they say "for testing with soda." I don't think it will leave the iMac 20.1, 20.2, and MacPro without sound. But this may be the last Hackintosh.

EFI-Folder-Distribution 

 

Below the link to my universal EFI-Folder for all recent versions of macOS (also works with Sequoia and Tahoe) with focus on X299 and SMBIOS macPro7,1. 

 

 

 

Please add/delete or enable/disable all system specific kexts for your build in EFI/OCI/Kexts and config.plist -> Kernel -> Add . 

 

As an already implemented option, you can choose between IntelLucy.kext or SmallTreeIntel8259x.kext (for Tahoe only use SmallTreeIntel8259x-KGP-Tahoe.kext) for your NICs (Ethernet), by enabling/disabling the latter in config.plist -> Kernel -> Add.

 

Boot the Tahoe installers with Whatvergreen.kext disabled and reenable Whatvergreen.kext subsequently to the macOS installation/update, if deemed necessary despite proposed macPro7,1 SMBIOS. 

 

Complete your SMBIOS credentials with Opencore Configurator (OCC) and use your own USB-Mapping-Kext before booting with this EFI. If you don't have any, follow my XHC USB Kext Creation Guideline (sorry, this guideline is not in any other forum). 

 

For the adaptation of SSDTs and ACPI-patches in EFI/OC/ACPI, config.plist->ACPI -> Add and config.plist->ACPI -> Patch (by default everything disabled), see my else partly outdated installation guide for Mojave.

 

Good luck 👍

Those machines are apparently using the Terminator 2 (T2) chip for audio, except the MacPro of course and I hope for our sake they bring it back in beta 3 😁. In the meantime I am enjoying quality sound via usb c in my hybrid MacPro laptop 😜

So frustrated.

So strange — I did a clean install, and everything goes fine until the first reboot. After that, everything just vanishes, lol.

When I get back to the boot menu after the first reboot, there’s no USB installer and no SSD Tahoe option to boot from. The only thing showing up is the Sequoia NVMe drive.

Update: 2nd attempt i got this:

Like @Irish_Man, Beta2 was not showing up initially on my system (Skylake NUC6i5SYH with iMac20,1 SMBIOS) but appeared in the software catalog from terminal.  Downloaded the full installer from there and used createinstallmedia command to create the USB...

Some observations

• I updated my EFI to latest OC and kexts and made sure the USB installer booted properly before upgrading my DB1 Tahoe volume to DB2. 
• The major difference from DB1 is loss of audio due to absence of AppleHDA.kext, fixed by installing VoodooHDA.kext in /Library/Extensions folder following @Slices instructions here.  DB2 is also quite happy outputting audio to USB audio devices eg my cheap QCY H3 headphones can be connected to the computer via USB C to A cable.
• I toggled SIP off from the OC boot menu before manually installing the VoodooHDA kext using the sudo command. 
• Besides requiring SIP to be disabled, VoodooHDA works nicely for audio output through the headphone jack.  Unfortunately, I did not have any luck with Intel HDMI audio, even though HDMI appears as an option using VoodooHDA.  To avoid any conflict between AppleALC and VoodooHDA while booting Tahoe, I set MaxKernel for AppleALC injection in OC config.plist/Kernel/Add at 24.99.99 (macOS Sequoia).
• FileVault on my system was already off before the upgrade and did not get turned on automatically during the upgrade process (don't know why some systems are and why some aren't).

To mount EFIs, I've always used "ESP Mounter Pro," which is quick and easy, and I've translated it into my native language. I don't like using OpenConfigurator, and I find it somewhat cumbersome. But with Tahoe, I haven't been able to get it to work correctly in beta 1 and beta 2

 

I use EFI Agent by @benbaker76 for mounting/unmounting EFI partitions ---> still works in Tahoe DB1 and DB2 (same author for hackintool)...
