Whenever there is a new update for Opera, it automatically downloads the update, but when it tries to open I get this error:
macOS will simply not open it and deletes the file. Opera then tries to download the update again, and macOS shows again the same error. A never-ending loop leaving my Opera unable to update.
I already checked the in preferences to allow apps downloaded from everywhere:
I really don't know if there is any other setting I have to adjust.
The way I'm updating Opera is to manually download the full installer, and run it. But I definitely prefer updates to be run in the background and automatically.
