Is Mac OS based on Linux Operating System?

Mac OS is based on a BSD code base, while Linux is an independent development of a unix-like system. This means that these systems are similar, but not binary compatible.

@JeMa You're welcome!

thank you @dave, it's helpful and not only for me

I never thought MacOS is similar to Linux, I thought MacOS is like Windows but created by Apple :/

@Calvin Wait, holy cow, man, damn, There must be a hidden Terminal does it?

@COMPL3X All android phones also based on Linux Operating System, in case you not aware.
