yes, any mac released after 2007 is 64 bits compatible.

Unfortunately, 64 bits code on core 2 duo is slightly slower than 32 bits ...

The Qt wiki states 10.7

All my real macs are version 10.10.

I used to build my packages using a 10.6 VM as it was the only way I
found to make a universal build that could work on 10.5 and later.

When I build, I set the minos requirement as 10.7 ; now wheither
something build on 10.10 will work on 10.7 remains to be seen.
