[macOS] Unity kernel crashes Mac with OpenGL when only Intel Graphics are present



How to reproduce:
1. Open the ("Crash Unity") project

Expected result: Unity runs fine
Actual result: Unity crashes the whole OS

Reproducible with - 2019.3.0a10, 2019.3.11f1, 2020.1.0b8, 2020.2.0a9
Not reproducible with - 2018.4.22f1, 2019.3.0a9

Using -force-metal argument fixes the problem until Library folder is deleted

    Resolution Note (fix version 2020.2):

    OpenGL is being deprecated from Apple platforms, the workaround is to switch to use Metal on Standalone target (Editor uses Standalone settings for deciding which Graphics API to use).

    We're still experiencing kernel panic crashes in Unity 2019.4.9 app builds running on MacBook Airs. (Case 1271751)

    I encountered this kernel panic when upgrading 2018.4 to 2019.4 on a 13 inch 2020 MacBook Pro.

    I ended up using the -force-metal command line argument and it fixed the issue for me.

    You also don't have to launch Unity from the command line if you're using Unity Hub, you can add the -force-metal command line argument under "Advanced Project Settings" for the project you're trying to launch.

    I got the same issue. to macbooks starting crashing and reboot after a project.
    This project was migrated from 2019.2.
    I removed projectsetttings file from project and let unity recreate it.
