You can exchange files seamlessly between QuarkXPress software and QuarkXPress Passport software for Mac OS and Windows.
Note: You will need to ensure that you are working with font types and formats that are supported on both platforms. In addition, make sure the image file formats and previews saved with images can be read on both platforms.
QuarkXpress Passport is available in QuarkXPress 6 & 7 only.
For QuarkXpress 8 and 9 we have QuarkXPress Plus Edition.
