I do not have another adapter, but for the purposes of the test I can remove it from the PCI slot

yes, boot without the nvme in and see if it reaches the macOS installer

Without the disk and adapter, the installation stops there. Is the drive or the adapter to blame?

Hello Everyone!

Unfortunately, I also have no luck installing MacOS Big Sur on my Dell 5820 Tower-X. Here is a short specification:

Dell Precision 5820 X-SERIES Tower Workstation
Intel Core i7-9800X
32 Gb (4x8) Ram 2666 MHz
Radeon Pro WX4100 GPU

I have already tried different configurations. Unfortunately, to no avail.
Below is my EFI folder. Do you have any ideas?

Are you installing Mojave? Or Big Sur?

Are you installing Mojave? Or Big Sur?

Big Sur. (11.6.0)

I added to my configuration USBInjectAll.kext. I also updated OpenCore to latest version (0.7.8). kext's is also up to date.

XhciPortLimit is broken in Big Sur

Sorry. My mistake. In the evening I will create a new thread in the appropriate section.
