Mac users: have you used Reikan Focal AFMA utility?

and is it reliable on your OS (10.6.8 to 10.10.1)

Yes. Latest version 1.9.10 working fine for me with a 6D on a Mac Mini with Yosemite (10.10) and Mac Air with Mavericks (10.9). No crashes so far on this version although I did experience that on some previous FoCal versions over the past few years with previous MacOS versions.
