I too have migrated to a mac from a pc. I had continued using TurboCAD pro v.12 by running windows virtually on my mac (I used parallels for mac and have been very happy with how it runs). I was interested in hearing that there was a new version of TurboCad Mac pro coming out and thought it was time to upgrade. But have not been able to get any answers out of IMSI about it.
I have been told three different release dates (the lastest, which I received today, was "sometime in January"). I have asked about features and the three reps to whom I spoke were unable/unwilling to tell me anything about the software, recommending that I download the deluxe version and check the forum (which you can see is not well maintained). I asked for a feature list or spec sheet and was told there wasn't anything available. I was told the Forum would provide all of that information. Perhaps I haven't looked in the right place, but I have not seen any information about the features on this forum.
I also make use of the quality rendering and materials features in the PC version and can not find out if these will be supported in the Pro mac version.
I did get a little bit of information. I was told that it is not possible to open TurboCAD PC version files in the mac version. You must export them as DWG files and then import them. Doing this in the Deluxe version results in the loss of quite a bit of information. If it will work better in the pro version, no one will tell me. It surprises me that a company would not even support files created in their own software. The best advice that I received from IMSI was to buy the most recent PC version because it would be better than anything that came out on the Mac. Given the perceived lack of interest by IMSI in developing and supporting the mac version, this is the way I guess I'm going to go.
