Installer gets stuck at Ethernet [IntelMausi]

[wbreiler]

The installer USB gets stuck at Ethernet [IntelMausi] and freezes for a few seconds before giving me the "not permitted" symbol. I've followed the Dortania guides, but no such luck. I'm plugged into a USB 2 port, and i've tried all ports on my computer. I'm using your BIOS settings, too.

weird, I've never seen an issue like that before. Try removing the kext (temporarily) and see if you can boot the installer. (Don't forget to remove it from the kext folder and your config.plist) If that works, and you need ethernet to setup macOS, try the AppleIntelE1000e.kext (ill add this to my repo now)

[wbreiler]

Thank you!

[wbreiler]

That didn't fix anything... :/

[wbreiler]

I changed to AppleIntelE1000e and it didn't change anything... :(

[joepool]

so you're saying that you have removed intel mausi kext from the kext folder, and your config.plist, but you are still getting an error related to intel mausi? that can't be right. Any chance you can attach a higher quality image of the error you are getting stuck on, as I can't read the one you have posted.

Here's the error once the ethernet kexts are removed in both the kexts folder and the config.plist

well that looks like a disk problem of some sort. I'm guessing you are using an nvme ssd (with a pcie adaptor or something). the second line from the bottom also suggests an install media problem (waiting on boot uuid media) does the activity light on your drive stop flashing at this point? I would suggest removing all internal drives and trying to boot the installer again. could you also give me a full list of your hardware, so I can help out better?

CPU - E5-1650v2 
RAM - 4x4GB Samsung DDR3 ECC
GPU - EVGA GTX 960
Drives - Intel Pro 2500 SATA M.2 SSD in a PCIe riser; Toshiba KXG5AZNV256G NVMe SSD in a PCIe riser; Hitachi H3D5001672S; Seagate ST1000DM003; and a Seagate ST500LM021

I'm trying to install High Sierra. I've removed all the internal drives, and I recreated the USB. Still no luck. And at this point, yes, the activity light on the USB does stop blinking

[joepool]

okay, I feel like this could be a gpu issue, as removing the nvme drive didn't help. have you removed the SSDT-GPU-SPOOF.aml? you could also try the nv_disable=1 boot argument. note that I have never tried the open core efi on anything other than Catalina and BigSur.

[wbreiler]

I removed the GPU SPOOF.aml I'll try nv_disable=1.

I got a little bit further...

Is my SMBIOS wrong? I'm using MacPro6,1

[joepool]

Ah I had that error. I never actually found a way to fix it, other than starting again with my EFI following the Dortania guide for IvyBridge-E, which seemed to work. MacPro6,1 SMBIOS is working fine for me on Catalina and Big Sur, but when I was using HighSierra I also had luck with the MacPro5,1 and iMac14,2.

I was able to boot into the installer, but mouse and keyboard aren't working...

[joepool]

Is your mouse and keyboard plugged into a usb 2.0 port? usb 3.0 won’t work at all on macOS. Also, what did you have to change to get it to boot?

[wbreiler]

Mouse and kb are plugged in to a 2.0 port, yes. I'm not sure what I changed, I just made the installer again and it decided to boot 🤷

[joepool]

weird, not sure what's going on with mouse and keyboard. id suggest trying a different usb 2.0 port, or a different mouse and keyboard if you gave them.

[wbreiler]

I've tried different USB 2.0 ports, and different mice and keyboards... not sure what else to try now... :/
