macOS Big Sur - No clamshell mode...

Robjfair · 12-12-2020, 10:19 AM

I have been experiencing the same issue using Universal Twin HD Dock through DisplayLink Manager on Big Sur.

The best workaround I have come up with until a solution is developed is to use the app Amphetamine (free in the app store) and set a trigger to not sleep while plugged into the dock.

I then set my external display(s) as the main monitor so nothing opens on my now shut Macbook Pro.

Only catch here is to remember to unplug your Mac from the dock after use so as to allow the Mac to sleep.
