We trying to build our game on Mac also, but performance is horrible. I know that Mac are not best place for gaminig but still, our game on lowest setting run in 5-15 fps.
Even esenthel editor is super slow, with most advanced option turn off and rather simple map, editor work only in 8 fps. (as you can see on screen below)

Are there any tips to run games on Mac, at least in way is playable?

mac we use is not best, but still rather good:
CPU: Intel i5 3,4 Ghz
RAM: 8GB DDR4 2400 MHz
GPU: Radeon Pro 560 4 GB

I've contacted Apple few weeks ago about similar issues and got no reply.
Mac is not for gaming, because Apple doesn't care about it, and not to mention OpenGL which according to Apple is deprecated.
But iOS is better.

You can try changing this to another mode :

However on my MacBook Air other modes had issues.
