It looks like you're still building OS-X the same way as in the past:
Intel 32+64 bit, 10.6 compatibility
Is that right?
Might it be time for an update?
Do we still need to support 32 bit? From:
There has not been a 32 bit-only Mac sold since 2006, and a out-of the box 32 bit OS since 2006 or 2007
I can't find out what the older OS version Apple supports, but I know my IT dept has been making me upgrade, so I"m going to guess 10.8 or newer...
And maybe we could even get rid of the "Framework" builds......
