I think that you should vote here if you would like support for Linux:

For some games native support for Linux is trivial (Darwinia or Never Winter Nights) many other games may only be possible via Wine and DOSBox.

I use Linux exclusively and most of the games purchased from GoG run without issue in Wine (a few games needed a little work to get running).

If Linux cannot be supported it would be nice to have Wine's Application database link with GoG so an indication on whether other people have got the game to work on Linux / FreeBSD or MacOS could be shown here and the GoG community could help out the WineHQ folks by updating the database. This would be a way of providing unofficial support.

I believe the gog wiki already does that. Otherwise people can just list it when they feel like it. I think part of the problem is that there aren't as many people doing it as is needed to make it work.

Which is why I posted earlier saying I don't think GOG needs to officially "support" Mac or Linux. As a Linux user, I think the community support has been more than sufficient for any troubles I've ran into (which have been few) playing GOG games.

I was merely saying that writing off any platforms to gaming just because you don't use them is short-sighted and incorrect. Playing Space Marine Shooter 6 isn't the only definition of gaming. Especially now, with GOG, and with indie gaming becoming big (The Humble Bundles have all supported Mac and Linux, every single one)... it's outdated and foolish to say one simply can't game on Mac or Linux.

Is it as simple or as full-fleshed as Windows? No, but we're not all gaming the same way.

Which I wasn't doing and you weren't saying.

And for a forum.

nullzero I didn't see you in my recent poll of linux/mac users. It was quite a bit down from one run last year.

Well playing through DosBox is pretty much identical on the Mac and Linux to the PC (in fact we tend to suffer from the exact same technical issues across all platforms if there are any) and many of the newer games I don't think GOG supports like the older ones. For instance, for Trine, I would contact Frozenbyte for support, not GOG regardless of the OS. So for the very old, DOS, titles and the very new titles with native Mac/Linux versions, there should be only very limited added support issues for GOG. It would not require a whole new support team for DosBox/new titles. All that is required then is renegotiating contracts with the rights holders (admittedly not an easy issue and could take a lot of time for all of the DosBox games).

So I think GOG could feasibly add Mac/Linux versions to a substantial fraction of their catalog without overloading their support (any more than it already is at any rate). But I understand why they didn't support Mac/Linux right off the bat and why there is inertia to change. Thus, while I think they can offer games for those platforms fairly easily, I'll just wait until they do so and port the games myself 'till then. The DosBox games which would be the most likely to come over first are so simple to get working that the fact that GOG doesn't officially support them on Linux or Mac actually means very little - the only thing tricky required is getting the files out of GOG's .exe installer which is straightforward with WINE.

As for the rest of catalog, WINE is actually working a lot better these days and for many GOG games it is relatively easy to get the games working and many of the rest can be gotten working with a little extra push. But even so, no I wouldn't expect GOG to anytime soon or perhaps ever to offer WINE versions of Windows games (unless/until WINE ever reaches the point where DOSBox is at now where practically all games are port and play). That said, CDPR used what seems to be a standard WINE engine to port The Witcher 1 (they may have tinkered with the game's files a bit though to do it - the jury is still out on that). For those games though GOG really would be on the hook for support and would be qualitatively more difficult to support, or at least different from supporting, than just normal Windows versions. However, some of my games run better and are more stable through WINE than in Windows 7 - a factor which will probably get more, not less true as time marches on and new Windows operating systems come out and WINE continues to improve.

I believe Navagon is right, CDPR (the developer) and GOG are sister-companies. CDP is the parent company to both companies.

Oh, it is a real market. Steam didn't create a Mac client and start selling to and supporting Mac users as some act of charity. There was money to be made and for that same reason, GOG could make more money too.

Of course, money has to be spent to make money. What else is new under the sun. I really don't get why people are so negative about the idea of GOG serving the Mac and Linux markets as well. So what if they are small. All income is good income. Those markets are smaller sure, but they are markets with potential just the same.

There are people selling to both Mac and Linux users too and they are not charities. They are businesses with the primary goal of making profits.

I like how people will make statements such as "It's not likely here" when they don't actually have any clue what is discussed by the people at GOG or what market research they might do, etc. For all we know, they are already carefully examining the possibilities and may yet also choose to act on them. I wouldn't be so sure about knowing things when one doesn't actually know them at all.
That's simple. The Mac is a nice computer with an elegant interface and a solid OS beneath it. In simpler terms, maybe you prefer one kind of automobile and I prefer another kind. They are both cars but we have our own individual preferences that guide our purchasing decisions. Isn't it nice to have choices to make instead of everyone being stuck in the same sedan, computer, OS, etc.? I think it is.

Why wouldn't a Mac user want to play games on their computer?
That is an interesting way of looking at it but the fact remains, they are both computers and are both capable of doing exactly the same things.
were more powerful? now you make me lol... A quad core i7 isn't powerful enough for you? Do you have something better in your PC? Too funny. I'm not sure why you care enough about a competing personal computer platform to hate it.

Yes, but how many copies? Steam doesn't guarantee that the game will run on Mac just by porting the infrastructure over to Mac, anybody that wants their game to run on Mac also has to make the adjustments necessary to make it happen.

Is it eough to justify the work? I don't know it depends a great deal upon how much work there is to do to make it work. Games running on MS libraries and using MS APIs are almost certainly going to be quite a bit more expensive to port than ones using libraries available on OSX.

For Wine, while much better than it used to be, yes it can still be tricky to do and I wouldn't expect it anytime soon as I wrote earlier. But for DosBox and the native Mac/Linux versions ... should be easy and not require much added support (the new games are supported by the developers and the old games getting stuff working in DosBox is pretty much if not entirely platform independent).
In fairness, I think Navagon is referring to the time when Macs ran on PowerPC architectures and could thus differentiate themselves based on that from "Wintel" machines. However, now that their innards are pretty much the same, he sees no reason to get a Mac. I disagree (since I have a Mac), but I believe that is what he meant.

Steam doesn't guarantee much to anybody really. But in fairness, the terms are the same whether you purchase a game for Mac or Windows on Steam. Mac customers are not second class citizens with lesser terms of service. By all means you could read them for yourself to see this. There's no distinctions made.
Ah, okay. I see what you are saying there. I do see Intel as a plus though given the ability to dual boot into windows just for certain games that won't run on OSX and aren't available to me on a PS3.

Going forward, considering I plan to play on a console as well, I don't feel like I am making some great sacrifice by going with a Mac. I see myself gaining a lot given my preferences. To me, the Mac OS is like driving a Cadillac and the Windows OS is like driving a Chevy. They both get you where you want to go I guess but I'd rather take the nicer ride myself. Before I get flamed too much for that crack, yeah I know it is subjective but that is my view and an important part of why I want a Mac.

I love gaming but my personal computer is not just a gaming platform. It does much more. Gaming is just one thing my computer does. Now, the PS3 I think of being a gaming platform although even it does more than just that. Its focus is certainly squarely on gaming.

I could be wrong, but the Mac version of Steam doesn't even offer most of the games in the normal Steam catalog.

That may have changed or I may be misinformed as I don't use Macs, but I don't believe you have as many games available for OSX as you do for Windows with Steam.

For you maybe, but for Mr. and Mrs. MacBooks-look-so-good-in-a-coffee-shop it might be a different story. You have to remember that as small as the Mac market share is, the percentage of Mac users who have enough know-how to do stuff like that is even smaller.
So, you argue that Mac is a viable gaming platform because you can install Windows on it.
And how large is Steam's userbase compared to GOG's, do you think?

That is correct. There is a growing number of good native releases for Mac but there are many more of course for the dominant Windows platform. As I mentioned earlier, it turns out I already own over 50 releases for Mac thanks to Steamplay and there's some more on my wishlist there. So I'm happy with that considering my Mac can run windows when I want it to anyway, which I will sometimes for certain games.

World of Warcraft which I enjoy has a native Mac client and the upcoming Diablo 3 will also have a native Mac version which is cool. There's definitely good gaming to enjoy on a Mac and it's pretty much unlimited if you don't mind dual booting into windows sometimes.

No.
