Hello everyone. I bought Wizardry 6,7,8 on GOG several weeks ago,
and I've just seen that Wizardry 6, 7 on Steam are available for Mac.

Therefore I think that it is possible to make Wizardry on GOG support Mac.
Hope that this will come true :)

I second this. My attempts to get them running on my own have been less than successful and I don't want to have to buy them again on Steam.

Yes - GOG.com, please make Wizardry 8 available for Mac. It would be greatly appreciated!

Wizardry 6 and the original version of Wizardry 7 (which is an extra - not part of the main download, which only includes the "Gold" version of Wizardry 7) are DOS games, so if you manage to install them (wine is available for OSX, right?), you can just run them is dosbox without problems - in fact that's how you'd run them on Windows as well.

I bought Wiz8 recently on GOG and just got it running on my Mac with Wineskin. Created a wrapper and installed the Windows version into it - it worked immediately except that the videos were garbled. After some experimentation, I ended up installing the engine WS9WineCX12.1.2 and moved the 3dfx*.dll/glide*.dll files away from the 'Wizardry 8' directory. The video sequences are now playing fine, the rest looks OK, too. Sometimes it does not close properly on exit.

I'm not a Windows/Wine expert, and I basically just got there by trial-and-error, so it may be that I've done something else along the way that affected success :).
