Do any of these methods work to rotate a Sidecar display? Right now I’m using BetterDisplay to creat a dummy and then rotate and stream that dummy to the Sidecar display, but it’s a bit unwieldy and sometimes unreliable (due to an Apple bug apparently).
Unfortunately not, the system reports false for canChangeOrientation on a Sidecar display:
mac-utils ./bin/RotateDisplay sidecar 0
ID UUID Can Change Orientation Orientation Name
1 37D8832A-2D66-02CA-B9F7-8F30A301B230 true 0° Built-in Liquid Retina XDR Display
6 BF8D0007-9573-49E5-8130-75991ECB2F15 false 0° Sidecar
4 FB46E28E-5B98-475A-A610-C15237238C8D true 0° LG Ultra HD
The display does not support changing orientation: Sidecar [ID: 6]
