R 4.3.1 fails on Mac OS 14

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).

I had a look and can reproduce it. 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):

Do not use that build on other macOS systems that don't exhibit the 

bug. 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.

Cheers,
Simon

Dear Mac users of R and developers.


I recently updated to the Sonoma OS for Mac (14.0)? and it has a 

serious problem for graphics.

plot(1:10) creates a graphic window but I can not switch back to 

the console window using either command-1 or the mouse.

Anybody else having this problem?? Any suggestions for a patch?

I am running a MacBook Pro with M1 Max.
