I recently purchased the following games on GOG based on their system requirement indicating they should work. When I try to start any of these games I get an error:
"You can't open the application ..... because it is not supported on this type of Mac."

Broken Sword: Director's Cut
Minimum system requirements - OS X 10.6.8
Processor: Intel Core Duo 2GHz
Memory: 1GB of RAM
Graphics: 64MB

Ultima Underworld 1 + 2
Minimum system requirements - OS X 10.6.8
Processor: Intel Core Duo 2GHz
Memory: 1GB of RAM
Graphics: 64MB

My System Details:
2006 MacBook Pro 17" version: 1,2
OS X 10.6.8 (Snow Leopard)
Intel Core Duo 2.16 GHz
2GB RAM
ATI Radeon X1600 256MB VRAM

Any idea what is my system missing that prevents it from running these GOG releases?

Any alternatives to GOG that will run these games?

Thank you.

Solution Update:
Well, so far I have found that each of the 3 games above contains another version of the .app file inside its package and it seems to work fine without any modifications or additional software.

All I did was:
1. Right click on the App
2. Select the Show Package Content option
3. Run the App found inside the Contents > Resources > game folder

I did not have the time to play the games yet to find out what the differences between the App versions are or if there are any problems, but will update this post if I do later on.

You will want to clarify your question. GOG is a digital retailer of games , it sounds to me like your text is referring to GOG Galaxy which is a game client developed by them, different things though. If its Galaxy I cant help, am quite against clients. You can however goto the web page, login and under account -> library find the game, download each of the files and install them onto your machine like any other program, I.e. Not using the client at all. They should run then, if not you will get a message (probably) about why they didn't run. Or you could try support.

Your MBP is, if I remember well, the first model ( early 2006).

A first possibility is that these games, or rather the emulator used to make them work on a Mac , need a function that is not available on your computer / OS version . In that case, your only chance would be to find an ealier build of that game port that would be compatible with your hardware. Updating your OS is , due to Apple policies, not possible . Your system is not able to use the latest OS X version.

A second possibility is that Something is wrong with your OS or your user account. Not sure how you could address this unless you have a backup

A third, would be that you run in 32bits whereas these games require 64 bits. You could try running the 64 bits mode.

A fourth is a conflict with another application. Third party antivirus / firewall would be the choice suspect.

It wouldn't be the first time that GOG has misstated system requirements on its Mac-native games. Some games like Enter the Gungeon and Nuclear Throne run just fine on underspec'd Macs like my 2010 MacBook Air. Conversely, I couldn't get GOG's version of Avernum 4-6 to run on my 2006 MacBook, even though the versions I have from when I bought them direct from Spiderweb work just fine on that same hardware. This is just speculation on my part, but it seems like the issue is the 32-bit Core Duo CPU on your MacBook Pro. As I noted above, I had some issues running games on similar hardware with my 2006 white plastic MacBook. What you can do is:

a) Contact GOG support and give the same information you've given us here. Once you've worked though your troubleshooting options (e.g. reinstalling the game, rebooting your system...) In all likelihood they'll give you a refund, if that's what you'd like.

b) Upgrade your hardware: MacBook Pros with Core 2 Duo CPUs capable of running at least 10.7 should be reasonably affordable on the used market. Just avoid the ones with the faulty Nvidia GeForce 8600M GT GPUs. There's also Apple's refurb section too. :)

Of course, getting a new/another Mac isn't exactly the answer you may want to hear, so here are some other options for you...

Broken Sword: Director's Cut: This game has the original Broken Sword as a downloadable extra. You can use the data files from that to play Broken Sword in SCUMMVM, which supports Macs going all the way to PPC Macs running 10.2.8. You will lose out on the enhancements in the DC Edition, but at least you'll still have a perfectly playable game.

Ultima Underworld 1 + 2: Ultima Underworld 1 and 2 are DOS games, so that means you can run them in Boxer, which supports 10.6.x. The Mac version of those games uses a newer, modified version of Boxer called Boxer Standalone, which was likely built/compiled with newer Macs in mind. If you're talking about GOG in terms of GOG Galaxy (GOG's client software/store/game launcher), then there is an alternative; you can download the games yourself to your computer and use other means to run them, like in my paragraphs above.

Anyway, best of luck to you. Please keep us updated. Feel free to message me if you need more help.

Inside the app (right click on the App, show Package content and then go inside the folder Contents) there is a file called info.plist, which you can open with a Text Editor like TextWrangler. Inside the file there are some app settings and information, including that one for the minimum system requirements. For Ultima Underworld the relevant line is <string>10.6</string>, which means OS X 10.6 should be the minimum supported OS. I changed it to 12.6 (I'm on 10.11) and got the same error message like you. You can try to lower that setting to 10.5 or another lower value, maybe that helps.

I believe no one mentioned it yet, but you should maybe also contact GOG support about it. I checked the original Broken Sword Director's Cut homepage from Revolution Software and regarding the system requirements listed there the game should run on Leopard 10.5.8. From the game itself there shouldn't be really a big problem. The same goes for Ultima Underworld and the DosBox-GUI Boxer. GOG uses an adjusted (I guess stripped-down) version of Boxer. Rampancy already linked the homepage of Boxer, maybe you could download the original version and see if you can the original version.

I am not referring to Galaxy or any other client. I did download and install the games directly. When I try to run the games I get the error message: "You can't open the application ..... because it is not supported on this type of Mac."

The GOG support page indicates to me that they do not want to be contacted RE: Technical issues since that is the only inquiry option that does not include a contact form. That is why I am trying to use the Forums to resolve this.

Very good thinking Phc7006, I bet the problem is the emulator packaged with these particular games is 64 bit and I think this MacBook model has a 32 bit processor.

I thought that GOG would let you download earlier builds of the games, but I can't figure out where or how to find them. When I go to my GOG Library the download section shows only 1 build.

The hardware and OS is fine as I am able to run some other GOG games and everything else is working just fine. Considering the MacBook is 10 years old it is in really good shape. It has 17" screen and I thought it would be perfect to use it offline to play these old games.

Thank you for your time.

I wonder if I could use some other emulator to run the games.

I bet you are correct rampancy, it has to be 32/64 bit issue where the emulators for these games are compiled 64bit.

You are correct, I am not interested in a refund nor can I justify another laptop. The one I have has more than enough resources to be able to run these games.

Thank you very much for the suggestions, I will definitely try the Scumm VM and Boxer options. This is really good news. Thanks for that Duke, I will definitely try this when I get a chance and update this thread.

As mentionned above, for broken sword, you should be able to find a workaround using a 32bits version of ScummVM

For Ultima, you could try Boxer (boxerapp.com), for instance ( If I remember well, Boxer is compiled in 32bits )

Thanks for that Duke, I will definitely try this when I get a chance and update this thread.

Unfortunately he's right, the MacBook Pro from 2006 had only a 32bit processors:

Did you give the original Boxer version a try? If that one runs, there is at least a chance that also the version that gog uses will run and then it's just a setting problem.

Here is an interesting and easy solution for the Broken Sword: Director's Cut problem.
I looked inside the Broken Sword.app package and found another version with the same name inside which works just fine without installing anything or doing any modifications to it.

It's hard to know without exact model specification. Looking at this list there are both 32-bit and 64-bit 2006 MacBook Pros. The ones coming with T2x00 processor are 32-bit. The others, coming with T7400, are 64-bit.

@op: Open the apple menu and click on the "About this Mac", than click on "More Info...". There you'll find more specific information about your MacBook.

I just updated the initial post.
It is MacBook Pro version 1,2

I am pretty sure it is 32 bit.

That settles it. MBP 1.2 , or A1151 , is powered by a T2600 , 32 bits indeed
