note macOS is a part-proprietary, part-open-source UNIX-based operating system, as of OS X - the previous OS releases were not UNIX-based This leaves Apple Macintoshes as the minority interest mainly of a small minority of college students note The Mac was specifically targeted toward higher education, academics, and a number of "creative" types artists, writers, musicians, etc. A fairly small number of geeks, a decently large number of data centers and supercomputer labs, and many, many scientists also run Unix-like systems, particularly Linux. In particular, the majority of engineers, accountants, self-employed people and teachers use Windows PCs.

In the real world, the vast, vast majority (85% - 90%) of personal/home computers run some version of Microsoft Windows.
