Hello, folks!
I tired of problems with my PC, sell it. And, I am a happy Mac user, now.
Here, I buy some all-time cult games -
Baldur's Gate Trilogy, Neverwinter Nights Diamond Collection,Planescape:Torment...


I have licences on my games, but in "My Profile" ,here on GOG, I have only downloads for PC.
When I can to play this games on Mac?
I am ready to pay again, no problem!

Unfortunately only ones marked compatible for Windows + Mac are available at the moment.

EDIT: Gah, now the blue's are ninja'ing people too?! What has this forum become! :P

...unfortunately , troll losers live on every forum.
As I say, in this moments -
"sometimes it's better to suck, than talk" I know that, before writing - looking site.
Question was - when the game will be sold for the Mac?

Most likely never; not all of them had a Mac version and even those that did are not going to run on current versions of OS X. I switched from Windows to mac a few years ago and I don't regret it at all, but Mac gaming just plain sucks. Mac versions are more expensive, lack behind in terms of patches, get less attention overall, often lack features such as level editor and the developers are less likely to fix them when an OS update breaks things. The best company is Blizzard who give you both the Windows and the Mac version together, so you don't have to pay extra.

Your best choice is to get the Windows version of a game and get that to run. The most hassle-free solution is bootcamp: you install Windows natively on a partition and then you can boot up Windows and it will be just like using any other PC (a Mac is basically a PC with a custom OS). If you don't want to reboot your best choice is Wine and Crossover. Wine is free but it's not as easy to use a Crossover. Both run Windows applications without Windows, they tanslate the program as it is running. Wine and Crossover are not emulators, so a game can run as fast as on Windows, but of course not every game works equally well. Some work perfectly, some work poorly and some are unplayable.

There is also Wineskin, which wraps Windws applications into standalone Wine apps. It's similar to Cider, which is used for commercial games, except it's free. The Witcher is a commercial game that was ported using Wineskin. i use it myself and it's like playing an actual Mac version, except I made it myself. Since you mentioned Baldur's Gate and Planescape Torment, there are premade wrappers for download (you still need to add the game yourself)

make sure to follow the included instructions.

This is not going to do you any favours, and I *was* trying to help you. There is no guarantee that it will be.

More than likely - never, however you can try PlayOnMac or CrossOver (as HiPhish suggested). Also, there is GemRB project purpose of which is to re-implement Infinity Engine, but it's rather in early development stage and i can't recommend you to use it.

So, your car wasn't working as you expected (maybe it was your fault, who knows...) and you are exchanging it with a bike? Congratulations, from a gaming standpoint your choice was a right one O_o

GemRB project -
I think , Baldur's Gate is real epic cult game.
I am ready to wait 20 years, and finally buy it for money.

THANKS!

GemRB is fairly complete, at least as far as the Baldur's Gate games go. Icewind Dale II and Planescape: Torment are quite incomplete but progressing, the first Icewind Dale should be completable, and I haven't kept up with the project on a long while so I don't know about Heart of Winter.

Heart of Winder should be completable in theory but no one has confirmed it so far. In Icewind Dale II one can play the prologue but cannot level up yet (so, yeah, unplayable)

There is software outside the Mac App Store, too. This isn't iOS, you can install software from anywhere and even write your own using XCode (free on the Mac App Store) or even other developing tools. OS X is an open system (and most parts of it are even open source), no matter what other people want to make you believe.
