TurboTax for Mac cannot save tax files
The TurboTax for Mac program is currently not allowing some customers to save tax files.
Please try the Save As option by holding down the Option key when selecting the File menu in TurboTax.
If that does not work, then follow the instructions here to perform a clean uninstall and reinstall. Your tax file will not be removed during this process so long as it is saved in your Documents.
Then please reinstall the program, eject your CD if you are using one, update the program, and try again.
