I think you can prioritize any program for quite some time on a Mac, no need for
game mode to acchieve that.
- Start Photoshop.
- Open a terminal.
- Run
ps -ef
and identify which of the running processes is Photoshop. Take note of the process ID (PID).
- Run
renice -n -20 -p (put PID of 'Photoshop' here)
.
Be aware that
maximum priority is set with -20 and
minimum priority with +20.
nota bene: you could use
nice
to start Photoshop with higher priority with a shell script directly; as written
renice
allows to change the priority of already running processes. Boosting the bluetooth connection like in game mode seems unnecessary to me, obviously YMMV 😄
