p.s. i don't think the adobe website, and forums in particular, are easy to navigate, so don't spend a lot of time searching that forum list. do your best and we'll move the post (like this one has already been moved) if it helps you get responses.
It appears to be both Lightroom and Apple that I get error messages from. Separate windows. The LrC window has heading Error Report for "Lightroom Classic". It shows the same email address as I have on this forum, which starts with "jeff". I have clicked "Send report" on this dialogue window several times over the last couple days. I just did so again now. Thanks.
