MacBook windows automatically resizes, cutting off the top of the screen

My MacBook has just decided that it will change the size of the windows I am using.

Often the top (say in Safari, the bit with the URL) is off the screen.

If I try to move the window, the Mac chooses which size to use.

I can work around it, but there must be a more elegant solution.

MacBook Air 15″

The default macOS configuration is to have an app window fill the entire screen when the window is dragged/placed immediately below the menubar. Also, dragging a window to the far left/right side will enable tiling which will also auto adjust the app window size.


You can turn these options off if you wish. They are located in the "Desktop & Dock" System Settings. Scroll down to the section titled "Windows".
