I now have a CAD program for my Macbook it is Via CAD 2D/3D v6, and so far it is really great. Its very innovative, user friendly , and would not hesitate to recommend it. There is also a version for PC users.
Unlike Turbo Cad by Avanquest, its now been three weeks since I first contacted them for a upgrade to v16 deluxe for a Mac, as I was a registered user for the PC version. Apparently the person who looks after pricing has been on holiday and has been to busy to get back to me! Even though I have been bombarded over the weeks to take up the special price upgrade via e-mail. Now they don,t even answer my e-mails. So my advice to you is to steer clear of them, customer care whats that!
