 This doesn't do anything for me, but I suppose it's unsurprising because
 it's pulling the same images that I was already using. The real issue is
 that there are no images for Apple Silicon, and so Docker tries to emulate
 amd64 and fails. Now as to why I experience this and you don't...? I
 really don't know. Subtle differences in the OS's emulation ability? I
 thought for a second it might because you're on macOS Tahoe and I'm
 holding on to Sequoia, but I see that the reports from huzaifaalmesbah and
 noruzzaman explicitly mention Tahoe, so ¯\_(ツ)_/¯.

 Btw, I should have shared earlier that I do think this comes down to
 emulation: the PHP container always fails when it tries to run its default
 command — [https://www.php.net/manual/en/install.fpm.php `php-fpm`] — and
 its only log message is:


 {{{
 $ docker-compose logs php
 php-1  | qemu-x86_64: QEMU internal SIGSEGV {code=MAPERR,
 addr=0xffff9cdc06c4}
 }}}

 Just to be safe, I tried (re)installing Rosetta, but the outcome's the
 same.

 Corroborating the idea that it's `php-fpm` specifically:


 {{{
 # I'm able to start an interactive throwaway container exec'ing bash:
 $ docker run -it --rm  wordpressdevelop/php:latest bash
