Hi all,

I need some help troubleshooting my EFI setup. The attached EFI works perfectly with macOS Sequoia, but it fails with Tahoe.

I already recreated the USB kext using USBToolBox, but the system still hangs at

and a few seconds later it stops at

Could someone check what I might be missing in my EFI?

Thanks in advance!

Using USBToolBox to fix the Tahoe USB issues won't work. As it doesn't include the new entries required for Tahoe.

You would be better served using the latest release of Corpnewt's USBMap.kext in macOS to create the new USB kext.



Also your current UTBMap.kext contains 20 x USB ports, when it should only contain 15 x ports, seeing as this is an Intel system with a single USB controller.
