Hello everyone,

With the release of macOS Sequoia, I’ve run into an issue with our podium iMacs that are connected to projectors. By default, they no longer mirror the display to the projector screen, even when using scripts or third-party tools from GitHub.

Currently, I have to manually adjust the display settings to enable mirroring for each instructor who logs in.

Has anyone encountered this and found a reliable solution or workaround?

Thank you in advance for any suggestions!

I’ve had some success with this tool. You can use the CL tool in a launchagent or add the icon to dock. It’s not great but works well enough.
