@fabiosun, I had to go abroad and will be back in about a week, then I’ll be able to test a. Thank you!

@fabiosun, sorry for the misunderstanding. I’ve just repeated the test using my EFI with the config.plist and kexts included in Archive.zip. The result is exactly the same.

I’m using the EFI from above, made by svan71

Hi, thank you very much for your help and the updated config. I followed all your instructions - replaced the kexts, reset NVRAM, and booted from the Tahoe installer. However, the same issue remains: the screen shows a black Apple logo during boot, and the backlight on my Corsair Gaming K95 RGB...

I’m sending you the config.plist that I’m currently using with macOS Sequoia. All serial data has been removed, but the file is fully functional. Thank you!

Hi, Thanks for the heads-up. I’m doing a clean installation from scratch on Tahoe. I’m aware that Broadcom Wi-Fi isn’t supported on Tahoe via OCLP yet, so I’ll wait for support on that front. Could you please help me with the correct kext settings? Specifically: Which kexts should have...

Hi svan71, шhank you very much for your support and for fixing the usbport.kext for Tahoe, as well as adding your 6900xt.aml. Unfortunately, the problem still persists. After booting, I get a black screen with the Apple logo and the installation does not start. I double-checked my BIOS...

I've tried every possible solution I could find, but nothing works. Could anyone help me figure this out, please?

Edhawk,I’ve tried both the revised EFI you provided for the Tahoe installation and the one from svan71. The installer does start, but the process stops almost immediately after the Apple logo appears - the screen freezes on the logo with no progress bar movement, and the keyboard powers off...

Hi Edhawk, I’m definitely booting from your EFI - I double-checked it. However, the same issue occurs again: I only get a black screen with the Apple logo, and nothing else happens. The verbose text doesn’t appear at all, even though -v keepsyms=1 debug=0x100 are present in the config.plist...

Hey Edhawk, the same screen popped up again - still no verbose text showing.

Hi Edhawk, I tried the revised EFI you provided for the Tahoe installation. The installer does start, but the process stops almost immediately after the Apple logo appears — the screen stays on the logo without progress, and the keyboard powers off completely (no backlight or response). It...

Hi Edhawk, Thank you very much for taking the time to review and revise my EFI folder - I really appreciate your detailed work and clear explanations. I saw the changes you made: New SSDTs generated from my DSDT and added to ACPI with the companion patches. The Gigabyte-specific ACPI patches...

Hi Edhawk, Thank you again for your help! I’ve prepared a minimal EFI (Tahoe Install) based on your suggestions - WhateverGreen disabled, USBInjectAll + XhciPortLimit enabled, and AMD patches extended to Darwin 25.x. I’m attaching the installation version here. If you have time, could you...

Hi everyone, I’ve been trying for several days to get my EFI configuration working for macOS Tahoe on my system, but I haven’t had any success so far. Hardware Configuration CPU: AMD Ryzen 9 7950X3D Motherboard: Gigabyte X870 AORUS ELITE WIFI7 RAM: 64GB DDR5 5000MHz GPU: AMD Radeon RX 6900 XT...
