I’m on a Macbook Air running Mojave with a Sony TV connected as second screen (extended mode). The laptop screen is the primary screen (i.e. the one having the macOS tool bar)
When launching the Master’s Tool Kit from the launcher it always opens on the second screen, in full screen mode, so there is no way to drag it back to the laptop screen. (and then, obviously, when I click on “Activate Player Screen”, the “player screen” displays on the laptop screen).
I’ve tried to launch the Master’s Tool Kit before plugging the TV screen to be sure it will be launched on the laptop screen. But then, the 2nd screen is not detected by the software when plugged in.
I’m stuck in this chicken and egg situation, so far…
