macOS editor crashes

I've been experiencing daily crashes inside the editor.
Crashes happen at various times, however the most common is:
- While (or maybe after) recompiling.
- Upon pressing 'play'

Frequency? Within a half hour of starting Unity. Afaik these do not occur if you left the editor idling.

Here's a sample stack trace (MB 12" 2017, 16gb, High Sierra 10.13.6, Unity 2018.2.1f1).
Metal editor is enabled.

Tempted to once again revert my system to Sierra, after waiting it out over 6 months I expected that related issues got ironed out, now I'm not so sure.

I'm also using the experimental (is it still experimental?) incremental compiler. No proof that this causes the problem but I'll also try turning it off.

Going to test with another box soon.

Advice much welcome.
