HP 250 G7 OpenCore EFI

[k.kemic]

Hi All,
is there anyone who successfully installed Big Sur (11.0.1) on HP 250 G7, i5 8th gen, Full HD? Could you, please, share your EFI?

I tried to follow tutorial according to dortania. Attached is my EFI folder. After selecting install macOS Big Sur, laptop's display goes blank and after some time (> 10s) I get some info on screen. After that is goes blank. I would really appreciate any help. HP 250 G7, i5-8265u, 16GB RAM, 256 GB SSD.

OK. Adjusted accordingly. I've tried several times to install Big Sur on HP 250 G7 (i5-8265u) without success.
After applying the following fix (troubleshooting section):

• For older firmwares:
  • EnableWriteUnprotector -> True
  • RebuildAppleMemoryMap -> False
  • SyncRuntimePermissions -> False

boot moves to the point where it writes message "BuildActDeviceEntry exit".

Now it hangs on BuildActDeviceEntry exit!

Attached: screenshot of boot log, config.plist and content of my new EFI folder. I am using OC 0.6.3.

Any idea how to move further? Really don't know where else to look.

I used the latest one 2.1.8 (Nov 2, 2020). Tried again, downloaded and booted but nothing changed.

have a look at the other settings in post2 of the guide in my signature

enable:
RebuildAppleMemoryMap
SyncRuntimePermissions

If I set these two, it finishes much earlier (shut down). I don't understand what you mean with post2 and your signature. Could you, please, provide a link.
