[OS X] Replacing Finder
To replace Finder with any application, type the following command in Terminal.app:
defaults write com.apple.loginwindow Finder /Applications/YourApp.app
To restore te default:
defaults delete com.apple.loginwindow Finder
Like Finder, the application will automatically relaunch when it quits unexpectedly. It’s useful in case of an exhibition or kiosk use of OS X. However, I’ve had problems concerning CoreAudio’s latency in that mode before. You would need enough test before the critical use.
上記コマンドを使って、Finderを任意のアプリケーションで置き換える事ができます。ただCoreAudioにレイテンシーが発生したりしたので、使う前にはテストをした方が良さそう。
