I've tried to follow these instructions: http://www.macworld.com/article/146958/2010/03/move_itunes_windows_mac.html
but when I finished all I could do was open my old library under the shared area in the left hand pane.
I was using a portable drive from my music storage. I've installed software on the Mac to read and write NTFS and purchased a new portable drive using Fire-wire 800. I've copied my music from the old portable drive to the new and all other files and folders from my iTunes folder in Windows to the iTunes folder on the Mac, including the mobile applications folder.
The best I've achieved so far is to launch iTunes and then open what appears as a shared library. FWIW, the library was shared from Windows.
How can I get my stuff to show up as the default library, playlists, etc and just as important maintain my iPhone/iPad apps with their settings.
Any help is greatly appreciated.
