When using the editor on MacOS, under some seemingly random circumstances, if the user repositions, maximizes, minimizes, or moves the editor window between workspaces, the mouse pointer will no longer click or highlight its actual location within the editor.
Please see the attached screenshot for an example where the mouse is not hovering in the save button, but the save button is still highlighted. If I were to try and click save, the editor would not see the mouse pointer location as that position and instead would be somewhere below it.
I’ve owned multiple Macs and used Unreal 4.13 through 4.18, and this issue persists between systems and versions.
Current system is MacOS High Sierra, 2017 MacBook Pro
