Any options for a "headless" display?

[spinedoc77]

I'm trying to get a 2017 Macbook Pro running with a headless display. I need to use the Parsec program remotely, and it won't work unless a monitor is on. I've successfully used a Headless Fit GS HDMI dongle for years on my Windows PC so I wouldn't have to leave my monitor on. What it does, I believe, is just supply an EDID to the PC fooling it into thinking there is a physical monitor connected.

Anyway I tried this on my Macbook Pro via a USB hub (this one https://www.amazon.com/dp/B093FKT9BF?psc=1&ref=ppx_yo2ov_dt_b_product_details ). But after plugging the headless dongle into the hub the macbook isn't seeing it. I'm wondering if there is anything different I would do versus a Windows PC to get the macbook to see the dongle as a monitor. Barring that, if anyone had any alternatives.

What version of macOS? If Big Sur or newer the BetterDisplay app claims to be able to do that.

you should be able to do this without any adapter, as long as the MacBook is connected to power and the application is running, you can enable remote management/login. you may need an app to adjust the always on settings or change your power settings in the Mac and it should work fine. I do that with some older MacBooks and Mac minis no problem.
