- The default priority is zero, positive values are 'nicer' (that is lower priority) and negative values are 'less nice' (higher priority). Looks like Mac OS runs from +10 to -10. Use renice to change the priority of a process already running (from the renice man page on 10.5).
- Is there a way to give higher priority to an app? To be precise, i would like to give high priority to the dialer, so that if there is an incoming call while using other apps, i can take the call immediately (it's a phone after all).
I’m able to give and to set up a recurring payment, but the app befuddlingly has to switch out of the app to load a website in Safari in order to complete the process! What’s more, once a payment is set up, you’d better be ready to give that amount for life, as I am unable to delete or edit a recurring payment once set up.
There isn’t a easy menu in macOS to prioritise applications for high performance over others. I couldn’t get the Atmonitor software to work ,so I did some more digging and came across the renice command. I successfully improved the stream quality on OBS by prioritising the program.
Renice Command Explained
sudo renice -20 3524
To run the renice command you need to specify the priority number and the target application/process ID. In the example you can see the ID number for OBS streaming software, It’s under the PID column.
Give App Priority Machine
sudo renice (amount from high -20 to 20 low, Yes -20 the highest performance) (PID number from Activity Monitor)
Give App Priority Mac App
Open up Mac Terminal and write the command.
Note: ALL Applications are defaulted to renice 0!
Then hit Enter, and put in your administrator password (if needed).

That’s all, you should have now reprioritised your choose application. This is only a temporary change to your mac and all settings will go back when you restart.
