Reducing window size

[rayben]

For some reason when in an application and I want to reduce the screen size all I needed to do was click on the screen and move the curser to the edge of the screen and the curser would change to a 2 double arrow curser and I would then just drag the edge of the screen to reduce its size but this has now stopped ie the curser does not change and I cannot therefor reduce the screen size?

Grab the Rectangle app and you can use shortcuts to size your window however you want, entire screen, right half, left half, right top quarter, etc.

Rectangle

Move and resize windows in macOS using keyboard shortcuts or snap areas. The official page for Rectangle.

Resizing by using the border also works as long as you aren't in full-screen mode (where you lose the menu bar and Dock). In this case, you'll have to get out of full-screen mode and then resize. But apps like Rectangle are faster to achieve what you want.

It still works that way. Is it possible the app in question is full screen? If so, you can move the cursor to the top right corner and click on the green dot to exit full screen, then resizing will work on that window.
