So um I have been trying to get macOS Big Sur running on well unsupported hardware (specs below) this EFI was built for it, I boot into BaseSystem, open Terminal, change date, use UnPlugged, I even extracted InstallAssistant and also used already found .app, Install macOS Big Sur.app launches, I select disk, next, it says 19 minutes remaining, restarts, OC, select macOS Installer (there is also only “Recovery”), Apple logo appears, progress bar goes full round, appears again, like 30-35% progress bar is done, time remaining appears, 29 minutes remaining, counts down to 1, few minutes remaining, no change in progress bar, I let it stay for more than 12 hours, return to it as same as before, boot BaseSystem again, Startup disk, Select macOS 11.7.10, “Macintosh HD” appears in OC, one progress bar completes, second appears, stuck at end (full end), restart, re-try, this time stuck at 45-55%. Before that I had macOS High Sierra successfully running, I opened “InstallAssistant.pkg” there and installed, opened Install macOS Big Sur app, let it do, and stuck as before (technically after)
