Has anyone seen this pop up before?
We get this on random Mac's, possibly during new Safari Update.
I've got a user reporting this exact same thing. Did you ever find a solution?
I have a remote user running into the same issue. Fresh installed macOS 10.14.6 as of a couple of weeks ago. I'm waiting to hear back on when the issue started to try to figure out what may have prompted it.
Ever find out what caused this?
