I, too, have the same problem that Chase has. Yes, Java is installed and has been updated recently.
I then say the Wordle "Not working?" hyperlink and clicked it. It suggested that I download a .jar file, which I've done. However, after double-clicking it, instead of opening, the error message says: "The .jar file can't be opened because it is from an unidentified developer. Your security preferences allow installation of only apps from the Mac App Store and identified developers."
How do I set which preferences so Safari will identify and recognize this app?
Thank you.
