Hi, so we just went through a laborious process for a client who had upgraded OS X to 10.8 from 10.6, leaving behind Rosetta and the ability to run Quicken 2004 for Mac.
We were able to obtain the free version of Quicken 2006 for Mac from Intuit. Then, on an older Mac Mini running 10.6.8 we stepped from Quicken 2004 for Mac to Quicken 2006 for Mac. Then we exported a backup file and were able to run the Quicken Essentials File Exchange Utility to prepare the .qdfx file for the modern Quicken Essentials program.
We’re happy to do the same for you if you find yourself locked out of an early-version Quicken file by an OS upgrade or other scenario. Pay now, and email us a zip of your latest data file at Don@yourcomputergenius.com. Please send a separate email with your contact info, or call us at (503) 383-9243. Thanks!
