Why areA while back someone asked me why Free BSD, Ios and Mac were included with the Distros on DistroWatch.

Please note Ios is Linux based(I E a derivative of Free BSD) and Mac is based on Free BSD
Free BSD is not Linux and it is not Unix. All of these OS's are Unix like OS's and because Linux is also a Unix like OS they are all grouped together. Hope this solves some of the questions.
