This has been a previous topic for discussion but unresolved. I have Leopard installed on my powerbook G4 and am experiencing problems in installing software with .mpkg suffixes. The message returned is that 'there is no default application specified to open the document'. This seems to be a fairly common problem but one to which no one seems to have an answer!
The problem must lie with an installer within leopard but I do not know which application within leopard is configured to install .mpkg files or what I would need to do to reinstall this or change the settings within it!
I have used Pacifist as a short term solution -however I would be far more comfortable knowing that I do not have a gremlin within the operating system!!
The "application" required is Installer. If you select a .mpkg file then press COMMAND-I to open the Get Info window, you will see in the Open With pane what application is associated with that type of file. If it doesn't say Installer, then select Installer from the drop down menu and click on the Change All button. This should fix the association between .mpkg files and the Installer.
If for some odd reason the Installer is not listed in the drop down menu then select Other which will bring up a file locator dialog. Navigate to /System/Library/CoreServices/ folder. The Installer is in that directory.
