Apple disabled options do avoid App Nap in recent OSX versions.
Playing an inaudible sound marks the application for preventing to get
set to standby mode as well as App Nap mode.

even then it is likely only possible to prevent App Nap but not
sleep mode.
If Bisq is in App Nap mode offers cannot be taken as well the user loses
network connection and offers.
