How to Set the Primary Display on macOS Tahoe, Sequoia, or Sonoma

Using multiple displays with a Mac is a very common setup, whether that’s using a larger external monitor with a laptop, or running a multi-display desktop setup. It’s well known that large screens and external displays can really boost some peoples productivity, and one way to further improve your multi-screen Mac setup is by choosing which of your displays is the “primary display”. For the unfamiliar, the Primary Display in MacOS is the screen that shows the Dock, menu bar, desktop icons, and where apps and alerts open to by default, and yes, this can be changed in multi-monitor Mac configurations.
MacOS makes it pretty easy to adjust the Primary Display, but it’s also a fairly subtle feature that is easy to overlook, especially in modern MacOS versions like MacOS Tahoe, MacOS Sequoia, and macOS Sonoma.
