I am using Microsoft Remote Desktop app to connect to a Windows machine from my mac. When I start the app it goes in full screen (I don't see any of the Mac controls). I was used to switching back from the app to the Mac desktop by using CMD-Tab but for some reason this stopped working. When I press CMD-Tab I'm getting a task bar of the Mac applications that are running but when I try press on an icon nothing happens - I am still stuck with the Microsoft Remote Desktop app. How can I get back to from that app to the Mac controls?
Microsoft Remote Desktop automatically opens on another desktop space. You can quickly change between your remote session and the Mac desktop by pressing control + left arrow, and vise versa for going back to Windows.
You can also press control + up arrow to see all spaces at the top of the screen.
Try invoking show desktops F3
I have that programmed on one my mouse buttons. No matter where I am, I can get to wherever I want with a simple mouse click.
