macOS crash in 2019.4.0f1 when using OpenGL editor

Hi,

I'm attempting to convert my project from 2019.1.11f to one of the latest 2019.4.0f1, primarily for compatibility with Unity Assets on the asset store. I was working in the OpenGL editor in macOS in 2019.1.11 so I attempted to disable the Metal Editor in 2019.4.0, as colors seem to be off in Metal compared to OpenGL and shaders are all flipped except in Render Textures and in the editor itself where they're right side up. And of course manually flipping the shaders makes them work fine in the actual game but they would then be flipped in Render Textures and Editor instead. Overall I really just want to continue working in the OpenGL editor I had been using earlier.

When I disable the Metal Editor Support (it's in Project Settings -> Player), the shaders, colors, etc. go back to as they were in 2019.1.11f, as expected and just as I had hoped. Unfortunately, switching from the Scene view to any other tab, then attempting to switch back to the Scene view, causes my entire Mac to crash consistently.

I am using a 2013 Macbook Air:

macOS Catalina 10.15.4

"1.3" GHz Dual-Core Intel Core i5

4 GB 1600 MHz DDR3

Intel HD Graphics 5000

Reprehensible specs, I know, but both editors actually work perfectly well besides this OpenGL bug. The issue only occurs with the OpenGL editor 2019.4.0, NOT when metal editor support is checked. 2019.1.11f works fine in either editor.

Does anyone know any fixes? I'll be working in both versions of Unity for now and attempting to modify the shaders to work properly (I may end up just having to flip the actual objects with the shaders whenever they're used in a Render Texture) in Metal 2019.4.0. But it'd be nice to just work in the 2019.4.0 OpenGL editor honestly. Thanks in advance!
