On my mac (
macOS 10.12.6) I can't find a quick way to resize image thumbnails in icon view mode.
I remember many years ago, with Leopard, by using Ctrl + Scroll Up/Down it was possible to resize thumbnails.
Is there any way to use that functionality or third-party software that enables this functionality in Sierra?
I am using a normal keyboard and a normal optical mouse. Not a Magic Keyboard or a Magic Mouse.
