I'd second Adrien here. While we will drop support for OS X 10.5, Macs with a Intel GMA 950 (various 64bit-capable Macbooks, iMacs, etc.) are stuck at OpenGL 1.4 even on OS X 10.6.8 and 10.7.5 (there is no 10.8 support for these machines). For more info, see [1]. The affected Macs are perfectly capable to decode the most common codec / bitrate combinations including 720p, so we should keep support for them. Since GLSL 1.2 is supported on those machines, even the new shaders will run.

Best regards,

Felix
