I just upgraded to Scriv 3 and when I double click the file, it won’t open. It literally is like I’m not even clicking on it. It does nothing. What gives?
Welcome to Scrivener and its forums, toni.
I recommend that first you check that you’re using macOS 10.12 or 10.13 (which Version 3 requires in order to work). Assuming that you are, then I suggest re-installing Scrivener; possibly the copy that you have was somehow corrupted in the download.
