The installation of AC 10, together with previous versions doesn't work on Mac Intel.
Or, we install de Wibu driver of the installation CD / website GS (Intel version) : AC 10 will work, AC 7 and AC 9 don't.
Or, we install de previous driver : versions 7 and 9 will work, 10 starts up in demo mode...
Graphisoft is working on a new driver ?
