Lenovo ThinkPad E14 Gen5 AMD Ryzen 7 und Tahoe.

fabiosun Since I believe that you are the AMD Ryzentosh expert, I am wondering if you could help me fixing my macOS Tahoe install issue.

macOS Sequoia works really great. It's using NootedRed for driving the AMD Radeon Graphics (2 GB VRAM) and CPU Power Management works as well with AMD Power Gadget on all 8 Cores (AMD Ryzen 7 7730U)

I've added AMFIPass.kext and -lilubetall as well as -amfipassbeta boot-args but as soon as I start the installer, it exits immediately with [EB|LOG:EXITBS:START]

No clue what the issue might be. I've attached the config.plist, maybe you have an idea.

Thanks

config.plist

Thanks. I totally forgot to check those Settings. After updating the Kernel patches, the Tahoe installer starts. It still crashes at a later later, but I will figure it out eventually.

ST3R30 Are you sure NootedRed kext is updated and working also in Tahoe? in the initial Tahoe betas some problems with it ( i do not use it and i cant be more specific about this)

I have the latest official release installed (0.8.3). I will deactivate it for installing Tahoe and see if it makes a difference.

it's an iGPU, AMD Radeon RX Vega 8 according to my research. And since Apple never served Macs with AMD CPUs it's not supported by macOS. It's enabled by a kext called NootedRed.

Yes, it works in VESA mode then, no propertes or boot args required – maybe this works because of all the Kernel Patches for AMD CPUs. But the underlying issue must be something else, The installer keeps crashing late now.

EDIT: I deleted the volume, downloaded the installer again and Tahoe installed without issues.

Another Laptop done…

PS: I never though that the chances of getting modern AMD laptops to run macOS would be higher than getting 11th gen+ Intel Laptops to work… odd…

Pro tip: using LLMs for analyzing OC debug bootlog? Priceless!
