This is a good place to ask. I don’t know what Apple’s Mac App Store policy for apps that don’t support the Commmand-H shortcut. Apple does have a forum for paid developers where developers can ask questions about the Mac App Store. The forum is at the following URL:

Carbon would allow you to hide windows and applications using C++, but you can’t write 64-bit Carbon apps, which means you have to use Objective-C if your game is going to be a 64-bit application. The following Stack Overflow question may be of interest to you:

Is there a way to programmatically hide an carbon application on osx?

A black window would come up for 2 seconds, then disappear.
On linux, it works fine, it shows the images and quits instead if just displaying black.

I had an idea it had to do with the path, but trying to figure out all the little nuances of using Xcode as well as trying to figure this out was a little overwhelming.
But your post laid out my problem and told me exactly how to fix it. Again, thank you!

Xcode is really overwhelming for new users. Almost too much so, I’d say. When the command line looks like a more better alternative, something is wrong.
Should you really have to pick up a textbook to figure out how to get it to just work? I thought that was the mac mantra, “it just works”. It certainly doesn’t “just work” in this case lol

As a test I tried adding two folders, one named Images and one named Sounds, to an SDL project. After building the project I checked the application package. Both folders were in the Resources directory.

The first thing I did was move the Images and Sounds folders inside the Xcode project’s folder. Next, I added the folders to the project. After clicking the Add button, a sheet opened. I clicked the Create Folder References for any added folders radio button and clicked the Add button. In the Groups and Files list on the left side of Xcode’s project window were two blue folders: Images and Sounds. That’s how I got the folders to be added to the Resources folder inside the application bundle.

Examine your project’s Copy Bundles Resources build phase to see how the files are being copied to the Resources folder. In the Groups and Files list, there should be a Targets entry with a disclosure triangle. Click it and you will see the name of your target with another disclosure triangle. Click that disclosure triangle. Now you will see a collection of build phases. There should be one named Copy Bundle Resources. Click the disclosure triangle next to Copy Bundle Resources. Make sure there is a blue folder for each folder you’ve added to the project.

I hope this helps.
