I've been having trouble with multi texturing on Mac.
I have an active context. GL_ARB_multitexture is supported.
I'm not exceeding the count returned with GL_MAX_TEXTURE_UNITS_ARB.
But no matter what I pass to glActiveTextureARB the active texture (retrieved with GL_ACTIVE_TEXTURE_ARB) remains GL_TEXTURE0_ARB.
Same code works fine on Windows. Is there something extra I need to do on Mac?
I'm using 10.3.1 with a Radeon 9700
