Hi all,
please allow me to clarify what is happening:
After a fresh install of QuarkXPress unfortunately on some newer Mac models QuarkXPress crashes when trying to activate it. This only happens on models which have Firewire ports with an address that begins with a non-zero value and only when activating. It has nothing to do with Snow Leopard per se, although all affected computers seem to come pre-installed with Snow Leopard.
A workaround is to not activate QuarkXPress, which will continue to function for 30 days (if not activated).
The good news are that we know now exactly what's causing it and have created a fix which we are currently testing with a few effected customers. Once they all confirm it fixing the issue we will post it on our website. We expect this to happen within the next two weeks and apologize for the inconvenience this has caused.
To confirm whether you have an affected computer you can follow these steps:
1. Select About This Mac from the Apple menu
2. Click More Info
3. Select File > Save As and save it somewhere
4. Open this file in a text editor like TextEdit
5. Do a Find for the string "class IOFireWireIP"
6. Under that section there will be a line that begins with "IOMACAddress" and has a string of letters and numbers that begins and ends with a semicolon. If that string begins with a value other than zero then you have an affected computer.
