Many thanks for working on this.  Going 64-bit only seems very reasonable to me.  

Do you know what is the minimum version of OS X required for QT 5?  I believe I heard that 10.7 or later is required for QT 5.4 (or maybe 5.5) but I’m not certain.

With the release of El Capitan (10.11) right around the corner, the only Apple-supported OS versions will be the latest plus 10.10 (Yosemite) and 10.9 (Mavericks).  Have you worked out how far back you’ll build for?

Thanks again.
