Editor Crashes on Mac Every Few Minutes

I was surprised to see that this was not reported previously when I searched for it.

My editor crashes every few minutes. It doesn’t matter what I’m doing at the time. Data, crashes. Triggers, crashes. Saving the game, crashes. It will work fine through any activity, but will randomly crash after 5-10 minutes of use. Been like this for months.

Works fine with Windows through Parallels, albeit a lot slower.

MacBook Pro (Retina, 13-inch, Early 2015)
Processors 3.1 GHz Dual-Core Intel Core i7
Memory 16 GB 1867 MHz DDR3
eGPU Radeon RX 560 4 GB

The same issue happens if the eGPU is not connected and I’m using integrated graphics. So that’s not the cause.

Bump. Does Blizzard provide technical support for Mac? The editor is literally unusable.
