How to set the default window size of Finder in macOS
I copied this from another tech support site (I don't recall which at the moment): Open a new Finder window. As you resize the window, hold the Command ⌘ (not Alt / Option) key. Close resized window. Then hold the Alt / Option key as you right click on Finder in the Dock and click Relaunch. Any Finder windows opened after this will open at that size. Note: This does not work for windows opened from folders on the desktop. #TechTuesday
