glDrawArrays from iOS to OSX

I'm trying to get a game I made for iOS work in OSX. And so far I have been able to get everything working except for the drawing of some random generated hills using a glbound texture.

It works perfectly in iOS but somehow this part is the only thing not visible when the app is run in OSX. I checked all coords and color values so I'm pretty sure it has to do with OpenGL somehow. 

glDisable(GL_TEXTURE_2D);
glDisableClientState(GL_TEXTURE_COORD_ARRAY);
glDisableClientState(GL_COLOR_ARRAY);

glBindTexture(GL_TEXTURE_2D, _textureSprite.texture.name);
glColor4f(_terrainColor.r,_terrainColor.g,_terrainColor.b, 1);    
glVertexPointer(2, GL_FLOAT, 0, _hillVertices); 
glTexCoordPointer(2, GL_FLOAT, 0, _hillTexCoords);
glDrawArrays(GL_TRIANGLE_STRIP, 0, (GLsizei)_nHillVertices);   

glEnableClientState(GL_COLOR_ARRAY);    
glEnableClientState(GL_TEXTURE_COORD_ARRAY);
glEnable(GL_TEXTURE_2D);

Appearantly it was being drawn after all, only as a 1/2 pixel line. Somehow there is some scaling on the vertices in effect, will have to check my code.

You're disabling the texture coordinate (and color) array along with the texturing unit, yet are binding a texture coordinate pointer.

Is this really what you intend to do?
