Move Window by clicking on any part (as on Linux)?
On Linux (or X in general), it's possible to move a window while holding down a modifier key (Alt+drag or Super+drag) and clicking on ANY part of the window.
This makes moving windows super easy, as one doesn't have to aim so well ;)
On macOS (High Sierra), this doesn't seem to be enabled/possible by default.
How do I enable this or what add on do I need?
Solution 1:
You can use the free utility called "Easy Move+Resize", which allows you to use Cmd + Ctrl + Left click anywhere inside a window to move it. The modifier keys can be customized so that you can choose for example Alt + Left click instead.
You can download the utility from here:
https://github.com/dmarcotte/easy-move-resize
Read under the heading "Installation".
Solution 2:
If you have High Sierra or later you can do this natively with macOS, no 3rd party app required:
Run this command in terminal to enable Ctrl + Cmd + Click in any window to move. Restart after.
# to add
defaults write -g NSWindowShouldDragOnGesture -bool true
Run this command in terminal to remove this functionality. Restart after.
# to remove
defaults delete -g NSWindowShouldDragOnGesture
