Thanks for that suggestion; it wasn’t the answer, but it did lead me to rewrite
significant portions
I’m not sure if this is related or not but this is the only item that I have
seen (albeit on iOS) where the UI simply would not update on the main thread
and it only happened on an iPad.
This was issuing a makeFirstResponded to a UITextField to display a keyboard.
The keyboard display simply d

In your background task which attributed string are you modifying? From the
looks of your ‘updateUI’ function it seems like you are modifying the one that
NSTextView provides, which is likely to actually be an instance of
NSTextStorage and sending callbacks to the NSTextView to update itself – w
