==> Caveats
Emacs.app was installed to:
  /opt/homebrew/opt/emacs-plus@30

To link the application to default Homebrew App location:
  osascript -e 'tell application "Finder" to make alias file to posix file "/opt/homebrew/opt/emacs-plus@30/Emacs.app" at posix file "/Applications" with properties {name:"Emacs.app"}'

Your PATH value was injected into Emacs.app/Contents/Info.plist

Report any issues to https://github.com/d12frosted/homebrew-emacs-plus

To start d12frosted/emacs-plus/emacs-plus@30 now and restart at login:
  brew services start d12frosted/emacs-plus/emacs-plus@30
Or, if you don't want/need a background service you can just run:
  /opt/homebrew/opt/emacs-plus@30/bin/emacs --fg-daemon

There's no build flag for this - native compilation is always enabled in emacs-plus@30 and @31.

However, you can disable JIT/deferred native compilation at runtime in your early-init.el:

;; Emacs 29+
(setq inhibit-automatic-native-compilation t)

This prevents Emacs from compiling .elc files to .eln on the fly. The AOT-compiled core files will still be native, but new packages won't trigger background compilation.

That said, native compilation has become much more stable after recent improvements - you may want to give it another try if you had issues before.

See Native-Compilation Variables in the Emacs manual for details.
