macOS Sierra 10.12.5 (16F2073)
On my Mac whenever any application (chrome, spotify, slack, etc…) enters full screen mode I cannot exit or interact with the application in any way.
- option+F11 does not result in any change
- option+F10 does not result in any change
- option+F9 does not result in any change
- option+F8 does not result in any change
- command+F does not result in any change
- command+shift+F does not result in any change
- command+control+F does not result in any change
- Mousing to the very top of the entire monitor reveals a menu bar which does not respond to being clicked
- Window control buttons (red, yellow, green – top left corner of the window) do not respond to being clicked.
- command+W does not result in the window closing
- If an application supports multiple windows (eg: chrome may have multiple windows with tabs inside of them), I can move the window around but I cannot interact with anything regarding the application (all of the above also applies to this sort of window).
I can only close the application via things like pkill -9 '<process-name>'
at the command line.
My question:- How can I troubleshoot this further as I'd love to be able to use full screen mode.

Troubleshooting is a process of elimination and often requires patience.
The first thing I would do is to test whether this behaviour is replicated in Safe Mode.
Boot into Safe Mode
Follow these steps to boot your Mac into Safe Mode:
When you're finished let me know how you went and we'll go from there.
If you find that you don't have the problem in Safe Mode, but still do after logging in normally again, then it's time to investigate login items, fonts, and kernel extensions
Investigating login items, fonts, and kernel extensions
Let's start with Login Items:
Now your Mac will boot up without those login items loading. Test this and see if the problem persists:
Fonts:- You can remove any of the fonts you've installed yourself to see if this makes a difference.
Kernel Extensions:- You can open Terminal (found within your Utilites folder) and enter the following command:
kextstat | grep -v com.apple
The above command will list 3rd party kernel extensions (you may need to stretch the Terminal window so it's easier to read). Look for anything you don't remember installing, or something that belongs to software you've removed, or just anything that looks out of place. Remember though, this is a list of 3rd party kernel extensions and therefore any of them could be causing the problem.
