I have a MacBookPro9,2 and an external monitor at my desk. Sometimes I unplug everything from the MacBook and carry it somewhere else awake with the lid open. I'll come back to my desk and plug it back in later.
On High Sierra, it worked like this:
- I have windows the external monitor.
- I unplug the external monitor. The windows move to the internal one.
- I plug in the external monitor. The windows move back to the external one.
Now I've upgraded to Mojave. When I plug the monitor back in, the windows stay on the internal monitor, instead of moving back where I had them before. I have to manually move them back to the external monitor for all of my Spaces.
Is this a setting? I haven't found one. Is there a way to get back to the behavior I had in High Sierra?
After several days, I've also realized that new windows sometimes open on my internal display, which has no menu bar. I expect them to open on the external one which has a menu bar.
