And what about the people that know Linux really well, but don't want so many levers and knobs to fiddle with? I use Linux for just about everything except my workstation. Mac OS is the clear winner there because I don't have to/can't really mess with any of the really low level settings, so I can actually work on things that matter. It's an appliance that makes me productive, not a pile of software and hardware that has to be endlessly configured (I used to run Ubuntu, then Slackware, then Arch). And is it really so surprising that Mac OS is so popular? You have a stable, non-moving target to build your software for, and you don't have to worry about "Well, what if they have version x of this lib instead of version y? Or what if this kernel config option isn't toggled on? Or.." and so on. There's something to be said for homogeneity, especially for software development.
