bug#43480: 27.1; Default font size not saving on Mac

[Germain Le Chapelain via Bug reports for GNU Emacs, the Swiss army knife of text editors]

Hello!


So, the default font options don't save across session on MacOS.

What I did is:

o clicked `Option > Set Default Font...'
o Reduce the font size (from 12 to 11)
o Closed the window
o Clicked `Option > Save Options'

Quit Emacs
Restart Emacs

I was seeing size 12 font again (and would see 12 selected in going back
to Options > Set Default Font')

I would have expected to see the font at the same size as saved in the
previous session.

:(

See bug#40796, maybe it will give some hints (although that bug was
not on macOS).

Basically, some of your customizations likely causes the manual
setting of the font size to be overwritten.

It's actually down to the way the font picker on macOS is implemented,
I believe. I've tried in the past to work out how to make it match the
other terms, but have had no luck.

Although a quick search shows David Reitter provided some code before:

    https://lists.gnu.org/archive/html/bug-gnu-emacs/2009-04/msg00704.html

I've no idea if that works.

\x10Thank you Eli!  It was a fresh install though, setting the font size was my first dabble w/ it.

\x10Yes it does!

Although I'm not 100% sure what that code is doing (Customize is
completely foreign to me) I've pushed the code to master under David's
name:

Fix font-panel on NS (bug#43480)

So I'm closing this bug (and I guess the millions of merged bugs we've
accrued over the years).
