When I downloaded Minecraft forge 1.12, it downloaded successfully, and the window on which you must select "Install Client" popped up immediately. When I try to open Minecraft forge 1.12.2, however, there is no such window, and all I get is a notification, asking me to "Check console for possible error messages." I've seen this happen to other users, but all the fixes which worked for them have done nothing to help my cause. Does anyone have any ideas?
I'm using a Mac OS Mojave, and Minecraft runs fine, so I'm assuming I have java installed.
