   OSX and GL2.1
  I have been away from the Mac for years now, and was thinking of getting a MBP with a 8600. I would like to know does OSX have support yet for GL2.1 yet? Mainly PBO and texture arrays?GL_EXT_texture_arrayGL_ARB_pixel_buffer_objectand how is the GLSL support on OSX as of now?Thanks   
  Wow no one here codes on a Mac? And no one here has a new MBP with a 8600?   ;  I have a MBP with an 8600 but I don't know the OGL support on it (spend most of my time working in Windows which is kinda ironic). I'd say ask over at iDevGames.com. There are lots of smart Mac programmers over there that I'm sure know the answer.   ;  This is the most reliable info I know of: http://homepage.mac.com/arekkusu/bugs/GLInfo.html   ;  Last I checked OSX was up to GL 1.5.  2.0 or 2.1 I think is part of the next OS release - which is 10.5   ;  According to the page linked to in the post above yours, depending on graphics card you can have 2.0 in OS X. That page is a very comprehensive page so I'd trust it.   ;  You'll have to wait for Leopard before you have OpenGL 2.1 support officially.   ;  Ok, I can wait that long... Anyone here have a new MBP with a 128MB VRAM in it vs. the 256MB VRAM version?I am just wondering how much of a performance hit you will take with 50% less RAM.
