After finding trouble updating the Preview preferences in BBEdit (the venerable text editor from Barebones Software), the company shared the fix.
My problem was the preference options didn’t recognize items I knew I had installed in /opt/homebrew/bin using Homebrew.
It turns out BBEdit runs as a non-interactive shell so it never loads my $PATH from .zshrc. The simple fix is to create a new dotfile in my home directory at ~/.zshenv and include my $PATH options there. A quick restart of BBEdit and everything I wanted was available for selection.
All of the details are provided on the Barebones site at Regarding environment variables when using “zsh”. Props to @BBEdit for responding to my question on Twitter in less than 10 minutes. The app is already awesome, but becomes more so because of the phenomenal support!
