SDL's Cocoa backend uses the CGDisplayMode API to get refresh rate information about a display mode, but CGDisplayModeGetRefreshRate will return 0 on most non-CRT monitors.
The only way I know of to get correct refresh rate information in OS X is via the CoreVideo DisplayLink API.
I have attached a patch which tries to use the CVDisplayLinkGetNominalOutputVideoRefreshPeriod function if CGDisplayModeGetRefreshRate fails, which fixes display mode refresh rate information on the monitors I tested.
The CVDisplayLink API requires linking with the CoreVideo framework, and the patch updates the various build files to do so.

The dynamic library (extracted from SDL2-2.0.3.dmg and put in /Library/Frameworks/) references the __Block_copy symbol in /usr/lib/libSystem.B.dylib, which cannot be found:
dlopen(/Library/Frameworks/SDL2.framework/SDL2, 6): Symbol not found: __Block_copy
Referenced from: /Library/Frameworks/SDL2.framework/SDL2
Expected in: /usr/lib/libSystem.B.dylib
From what I could gather __Block_copy seems to be related to the blocks extension to the C programming language introduced by Apple since OSX-10.6 (see: http://thirdcog.eu/pwcblocks/). If this is indeed the case, I don't think the SDL2-2.0.3.dmg on the website is at all compatible with OSX-10.5 countrary to what is announced.

I actually made a mistake when creating the previous patch file... I forgot to include a crucial line which changed.
I've attached a new patch which just changes the line I forgot, since the other part has already been applied to the repository.
I tested this one by doing a clean rebuild of SDL, and it works with the new patch.
This uses a better mouse grab if you define SDL_MAC_NO_SANDBOX. This
mouse grab uses CGEventTapCreate, which you cannot access if you have
sandboxing enabled.
Turned off C++ exception handling for all configurations and all platforms
Turned on comdat folding and optimized references for all optimized builds
