Window doesn't open when launched from the Dock or Finder

Steps to reproduce

1. Launch MacVim from the Dock or Applications folder
2. New window does not appear.
3. File -> New Window and File -> Clean Window does nothing.

I removed .vimrc, .gvimrc, .viminfo, and all plugins and the issue persists.

If MacVim is launched directly in terminal via /Applications/MacVim.app/Contents/bin/mvim, everything works as expected. Similar issue was raised in a Google Groups discussion.

Expected behaviour

A new window should appear when launching the app.

Vim configuration where issue is reproducable

No response

Issue has been tested with given configuration

• by running MacVim.app from GUI macOS interface
• by running vim/gvim/etc installed by MacVim
• by running other versions of vim (e.g. /usr/bin/vim)

Issue has been tested with no configuration

• by running mvim --clean (or gvim, supplied by MacVim distribution)
• by running vim --clean (in terminal, supplied by MacVim distribution)
• by running vim --clean (in terminal, other suppliers, e.g. /usr/bin/vim)

Inizia confrontando l’avvio di MacVim dal Dock o dalla cartella «Applications» con /Applications/MacVim.app/Contents/bin/mvim, poiché l’issue segnala un comportamento diverso tra questi punti di ingresso. Riproduci il comportamento della finestra mancante su macOS 15.0 con la versione indicata di MacVim, quindi verifica che venga visualizzata una nuova finestra quando l’app viene avviata graficamente e tramite File → New Window.
