DisableMonitor VS BackgroundMusic

DisableMonitor (free) - lets you apply a custom resolution to your internal or external monitors (e.g. 1920x1080) Available on GitHub

I'm wondering if the same is possible on an M1 machine—through a tool like DisableMonitor, can you force 8k resolutions on an M1? Or, if not, does selecting 4k run it truly at 4k (e.g. 1:1 rendering for blurrier visuals on the pro display), or does it render at 8k and downscale?

I use Screen Sharing to have my Macbook screen show on my iMac. Works flawless over Gigabit, except that cmd-tab sometimes lags. There are tools available[0] that allow you to set a higher resolution for a screen than what would be sensibly supported by the LCD panel. Although it doesn't do retina this way.

For controlling a software defined volume like Windows has, try https://github.com/kyleneideck/BackgroundMusic

Download Background Music: LINK (free and open-source) Once downloaded, run it and you'll see it as an icon in your menu bar

Thanks for the comment. I checked out Rogue Amoeba's SoundSource, and BackgroundMusic. I think they're using some sort of virtual audio device or something to intercept applications' audio data, control each application's volume, and then send it to the speakers (or another output device).

I had an app called Background Music that I deleted a few days ago, but it still shows up as an audio output in the Sound menu bar menu as well as in Settings.

you can check BackgroundMusic : https://github.com/kyleneideck/BackgroundMusic

Tried https://github.com/kyleneideck/BackgroundMusic before. But didn't work for me.
