Client on macOS "crashes"

Nextcloud version (eg, 12.0.2): 2.5.1
Operating system and version (eg, Ubuntu 17.04): Mac OS 10.14.2
Apache or nginx version (eg, Apache 2.4.25):
PHP version (eg, 7.1):

The issue you are facing:

On a regular basis the nextcloud client simply quits. I get no error-message, no nothing. The symbol simply disappears and I have to start the client manually again.

Is this the first time you’ve seen this error? (Y/N):
happens frequently

Steps to replicate it:

cannot really replicate, since I don’t get any error-message
