Huge version with MacVim GUI.

This is macvim: 8.2.2164,169 (auto_updates) installed as a cask from Homebrew.

When I launch MacVim using the mvim script from Terminal, it launches the app and renders a GUI window. Everything is as it should be.

But when launching from Finder (either Cmd-space and typing MacVim.app, or double clicking the app bundle from the Applications folder, the app runs; it creates an icon in the dock, it presents a menu, but it doesn't render a window for the editor. Cmd-O opens a dialog to select a file to open, but opening a file does not render an editor window for the file. The Window menu does not list any open app windows. It's running and responding appropriately, but not rendering a window when launched from Finder.

I've seen this behavior in several macOS releases now over the years. It's sporadic. When the issue occurs, it's frustrating and I move on, but at some point I switch back to the MacVim task and open a new window, and it just works as if there was never an issue.

As an experiment I backed up and removed my existing .vim/, .viminfo and .vimrc which are customized. Afterward, MacVim launched correctly (rendered windows) from Finder. I'll review settings but it's not clear to me why a customization would cause failures running from finder vs. running from start script in Terminal.

Bắt đầu bằng cách so sánh MacVim được khởi chạy thông qua script mvim với MacVim.app được khởi chạy từ Finder, sử dụng các tùy chỉnh .vim/, .viminfo và .vimrc được báo cáo làm các biến chính. Tái hiện hành vi cửa sổ bị thiếu với cấu hình của người dùng, sau đó xác định tùy chỉnh hoặc khác biệt nào trong ngữ cảnh khởi chạy ngăn cửa sổ trình soạn thảo được hiển thị, và xác minh rằng việc khởi chạy từ Finder hoạt động mà không xóa các cài đặt không liên quan.
