[R-SIG-Mac] R 4.3.1 fails on Mac OS 14

[Smith, Desmond]

Hi John,

You are not unique in noticing the apparently random (single) switching of R.app windows in previous versions of Mac OS X (Ventura).

I observed the same phenomenon, but simply lived with it, despite some close calls in code destruction… I had to keep my wits about me!

Cheers,

Des

Not to beat a dead horse, but it may be that this is the mechanism for
the spontaneous switching I was experiencing in versions for a couple of
years.  Don't know why I would be unique in that but it seems to have
been the case.

Just adding the observation in case it provides a puzzle piece.  The
underlying problem could go back a while (or not).

What happens is that macOS Sonoma is sending dozens of notifications that a window will close (even if no window is being closed!) and since we move the focus to the next window on close it happens every time macOS sends that notification and thus many times in sequence. Unfortunately it is not clear why Sonoma does it and it makes no sense, so some more digging will be required. I have added a quick hack to simply not change focus on close - it is not ideal as it doesn't address the (unknown) cause which may have many more repercussions, but it lets you try it out (R 4.3.x and arm64 only):

There are still more known issues with Sonoma (e.g., you cannot close an R document without saving), so avoid upgrading until it stabilizes more. In the meantime I'll see if I can find out more about the mysterious bugs in Sonoma.
