Hello. I just updated my iMac from Big Sur 11.6.5 to Monterey \`12.3
today, and suddenly, I got the following warning when I ran GNU emacs
(the one downloaded from [GNU Emacs For Mac OS
X](https://emacsformacosx.com/)) from Terminal:

    $ /Applications/Emacs.app/Contents/MacOS/Emacs
    2022-03-15 21:34:51.135 Emacs-x86_64-10_14[6713:94719] It's not
legal to call -layoutSubtreeIfNeeded on a view which is already being
laid out. If you are implementing the view's -layout method, you can
call -[super layout] instead. Break on void
_NSDetectedLayoutRecursion(void) to debug. This will be logged only
once. This may break in the future.

Of course, I can suppress these warnings by redirecting outputs to
/dev/null, but I didn't get such warnings on Big Sur. Is there anyway
to fix this warning instead of just redirecting the warnings to
/dev/null?

Thanks!

I'd by far recommend using [emacs-
plus](https://github.com/d12frosted/homebrew-emacs-plus) from homebrew
to install emacs for macOS. Additionally you can use it to compile it
from source, I'm using the master branch with native comp and
xwidgets.

I [build emacs](https://github.com/mclear-tools/build-emacs-macos)
myself from the master branch on an M1 and Monterey and don't see this
issue. So it might be something either with your config or with that
specific build setup.

Thanks a lot! I just installed it via homebrew, and now no such
warning messages are displayed!

Doom Emacs has a lot of information on running Emacs on macOS, I
recommend looking through their getting started section just for the
general information.
