I’m running OSx 10.6.8 and everything is ok, so I don’t upgrade.

I would never have gone beyond 10.6.8 except for the fact that some critical software, like Turbotax and iTunes, now require later versions of the OS.

I made a 10.10.3 boot drive which I only use when I have to use software that won’t run on 10.6.8. the ratio is something like 95% 10.6.8 and 5% 10.10.3.

As far as I am concerned, 10.6.8 represented some sort of peak.
