I am trying to install Big Sur on my XPS 9500 (CPU: i7-10750H, GPU: Intel UHD 630, Install method: Opencore) but I am running into issues with internet connection while installing. I grabbed this EFI folder, changed the SMBIOS info and made an installer (on Windows) and was able to boot it successfully. I also followed all of the BIOS settings they suggested. However, when I actually go to install the OS, it takes a long time and eventually times out with a PKDownload error. I've seen that doing an offline install may fix this, but I don't have access to a Mac so I don't think this is an option. What can I do to fix this?
