Thanks to the help of Sidney Markowitz from this thread => https://lists.gnu.org/archive/html/enigma-devel/2015-10/msg00001.html , I figured a solution : replacing SDL_Image 1.2.12 version by 1.2.10 version.

If I got this right, the catch is that 1.2.10 comes with old universal code which is not allowed on the AppStore, so submitting an App with this version would likely end in a rejection. So I'm going to try to recompile it with only x86 code, that should likely do the trick.

EDIT:

Instead of recompiling, I just used Lipo ( http://www.manpages.info/macosx/lipo.1.html ), like this :

lipo -remove ppc -output ~/Documents/SDL_image /Library/Frameworks/SDL_image.framework/Versions/A/SDL_image

And then moved back "~/Documents/SDL_image" to "/Library/Frameworks/SDL_image.framework/Versions/A/" . And finally I edited its info.plist to fix the Bundle ID (needs 2 dots in it) so publishing on the AppStore could work.

Thanks again to Sidney Markowitz for the Lipo hint ! :-)

EDIT2:

New version has been rejected by Apple, because SDL_image 1.2.10 uses a deprecated CGDataProviderCreate API. The code contains a "#ifdef" to use a newer replacement, so I'll have to recompile it instead of using Lipo, but I'm afraid this newer replacement is the actual source of the glitch on OSX El Capitan.

EDIT3:

Recompiling SDL_image 1.2.10 works, but not as it, I had to change the installation folder to @rpath and a few other parameters and then it was successfully accepted on the AppStore.
