A similar question was asked a few years back but I can’t seem to find a solution to my specific question.
Context: I have a Mac Studio Max with three external displays running MacOS 15.3.1. In Mission Control each display is assigned a separate desktop.
Goal: Assign apps to a particular display/desktop so that when I log in to my profile or otherwise restart or power-up my computer the apps I’ve designated to open at start-up will always open on a specific display/desktop.
Problem: This ability exists natively in MacOS Sequoia. However, I can only seem to get the preference to display if I create a fourth desktop. However, I have no need for a fourth desktop.
Question: How can I assign specific apps to particular displays when each display only has one desktop?
