boot after black image HP8570p

[sajtos888]

Hello. problem is that after boot when the apple logo should appear then i only get a black image. However, I realized that the installation starts just throwing the image on the Display Port to an external display and the laptop display is black.
sorry for the google translator.

Dont use external display for installing macOS

[sajtos888]

I don't want to use it but after loading the installer I only want to put the image on the external display even though no external display is plugged in.
so the laptop screen is dark

Give the complete description of the laptop, HP 8570p ? the exact CPU and the laptop screen size, also do you have another Graphics device ?

[sajtos888]

Cpu: I5-3210M
Screen size: 1600x900
Intel HD 4000
no other graphics device

[chris1111]

For a High Screen resolution 1600x900 you need to ad -igfxvesa for installing macOS

Thank You! 😄 Everything works perfectly. Except for Bluetooth I haven't been able to figure this out yet. Bluetooth worked with Catalina.

[chris1111]

What is the WIFI card you have?

[sajtos888]

Unfortunately the wifi card has not arrived yet.
Bluetooth is included. But to solve it I just had to add BrcmBluetoothInjector.kext in the OpenCore configurator.
It works.

Yes you have to Setup the bluthoot kext you have also to setup BrcmFirmwareData.kext

See Video after Install program , I do this
