Using the latest version of Unity on Mac, making a Mac build (86x), I’ve discovered that my builds no longer open. They’ll appear in the dock for a few seconds, and appear to be loading, but then the icon will disappear from the dock and nothing will happen. It doesn’t even reach the Resolution dialogue before closing.
I’ve tried restarting Unity, and restarting my computer, to no avail. Opening older builds does work. Only builds I’ve made since this morning have the issue.
I’ve been using Unity for a year, and this is the first time I’ve experienced this.
