Short description of error
I have only begun to use Blender 2.80 for one day and it has already crashed my Mac once, and froze both my computer and Blender itself on two separate occasions, forcing me to turn my Mac on and off.

My Mac crashed (shut itself down) when it was put on stand-by mode (MacBook closed) for an hour, with Blender still turned on - I assume this happened because of Blender.

When both my MacBook or Blender itself froze, it happened when I was learning how to sculpt for the first time (see below).

Blender - and not my MacBook - presumably froze because I accidentally gave a brush to much strength (10.000* instead of, for example, 1.000*) and used it for just one left-click.

Then my entire MacBook froze - without any sign that it was even loading - as I was sculpting, for no good reason. I was only just learning how to sculpt for the first time, so I probably wasn't very efficient or clean with my strokes, but not to a degree where crashing or freezing seemed called for.

Exact steps for others to reproduce the error
I don't know... I'm not sure if I did anything wrong (messy/inexperienced beginner) or if Blender 2.8 just isn't ready for Mac yet. I just hope that either someone can tell me what I did wrong, or that this issue can de detected and resolved in a future update.

Sincerely,
Lorenzo
