AppleScript可以確定默認郵件應用程序嗎？

Question

我想知道是否有方法使用AppleScript來確定當前的默認電子郵件應用程序是什麼。理想情況下，它會返回到程序的路徑，如/Applications/Mail.app或/Applications/Outlook.app。

您可以從啓動服務首選項文件中識別默認電子郵件客戶端。

在El Capitan文件位於~/Library/Preferences/com.apple.LaunchServices/com.apple.launchservices.secure.plist。在10.11之前的系統版本中，該文件可能直接位於「首選項」文件夾中。

set bundleIdentifier to missing value 
set LSPrefFilePath to (path to preferences folder as text) & "com.apple.LaunchServices:com.apple.launchservices.secure.plist" 
tell application "System Events" 
    set LSPrefFile to property list file LSPrefFilePath 
    tell property list item 1 of contents of LSPrefFile 
     repeat with anItem in (get property list items) 
      if exists property list item "LSHandlerURLScheme" of anItem then 
       if value of property list item "LSHandlerURLScheme" of anItem is "mailto" then 
        set bundleIdentifier to value of property list item "LSHandlerRoleAll" of anItem 
        exit repeat 
       end if 
      end if 
     end repeat 
    end tell 
end tell 
if bundleIdentifier is missing value then 
    set defaultMailClient to "/Applications/Mail.app" 
else 
    tell application "Finder" to set defaultMailClient to POSIX path of (application file id bundleIdentifier as text) 
end if
