Macs seem to be having a lot of issues with 1.8.10

Suggest roll back to 1.8.9 for now.

I am having exactly the same problems. Tried upgrade to 1.8.11 and now 1.8.12, still an issue!

It seems to crash when I move an Arduino window on screen. Sometimes just by moving the cursor over the window. Especially the titlebar seems to be sensitive..

Then at other times it seems to work to a longer time (15-20 minutes) where I edit compile and upload multiple times. Then suddently it crashes.

Reboot of computer does not help.

I havent got evidence yet, but I have a suspicion that crash is more common when I place the Arduino Window on an external display rather than on the Macbook's own. However, that is just at feeling and with no hard evidence

I'm having the same issue and you're definitely right about it being exacerbated by an external display. I have a 2016 15" Macbook Pro on MacOS 10.15.3 and Arduino 1.8.12 and as soon as I move it to my (external) 5k display, Arduino crashes within seconds. I deleted the application, wiped out the ~/Library/Arduino15 folder, and then put on a fresh copy of Arduino but the issue remained.

There are some bug reports about this:
