Thanks for all your hard work, Dan.
I think it may have been human error. Um… How can I make this seem less embarrassing for me?
I found a copy of the .dmg in my MacOS Dock, next to the trash. So, I simply missed dropping it on the Trash the first time, after install. It was re-appearing all afternoon and in a night owl session I had from 1-3 am, so I was tired and didn’t notice it in the dock.
I thought, I’ll shut down the computer and it’ll be gone in the morning. But it appeared when I restarted and then again after I trashed it and restarted again. I dragged it into the trash many times but it kept popping up. I was like, “What tha?” So I came here wondering if maybe there was an issue.
But then, I spotted it in the dock. Maybe because it was “open” in the dock, it just kept activating?
So far so good now, though. Thank you for following up!
