I don't wish to start a Mac-PC war, but seriously, I'd be more concerned if I was on a Mac. OS X upgrades have broken things. Colour management was broken back in 10.6.8 IIRC, which is why Print Tool is needed, and a recent OS X upgrade (El Capitan?) broke QTR for new installs until Roy released a fix. OS X may be more convenient now, but were Roy to be hit by the proverbial bus (heaven forbid), and another such break to occur ...
