I'll see if @macuser_22 can assist you any with that when he's next in the forum. If not, then you'll need to phone TurboTax Support on Monday. They can even push you the state software as a separate download if necessary. Users have said that pushed package installs well.
BTW, what Mac OS X are you using?
If you end up needing to phone Support, you can use the form at the link below to schedule a call back, or it may provide a number. Hours are 5AM-5PM Pacific (8AM-8PM Eastern) Monday-Friday.
Where the form asks what product you are using, be sure in the dropdown menu to indicate "CD/download" and the proper operating system, then indicate which Edition. Then for issue say something like Stuck in California state download/install loop (without quotes).
