OSX - built from UNIX

UNIX, is the foundation of Linux and OS X, it is not an OS itself. UNIX is like the powertrain of a vehicle. You can have several chasis or features after that.

 

OS X is 100% Certified Unix™.
http://en.wikipedia.org/wiki/Single_UNIX_Specification

Linux is a Unix-like OS. (Formally, Linux is the kernel, GNU is the software.)

OS X does contain a lot of open source material -- including some GNU software!

Actually UNIX is an OS. And Linux is UNIX-like, but does not use any UNIX source code.

 

I think you are making a unsubstantiated claim. Linux may be more popular than Unix, but I definitely would not call it superior. I believe it gets it's popularity because it has a lot of developers and thus supports more hardware. Apple makes their own hardware, so they have no reason to use a kernel that supports lots of hardware that they are not going to sell. I think they made the correct choice in using BSD Unix over Linux - they get a very stable kernel and don't have to deal with Linus's ego.

Don't get me wrong - I am a linux user and developer. I have created several commercial products using linux, however they are not consumer products and you will probably never hear of them.

 

The Linux people don't want to be a just a Unix: https://lwn.net/Articles/453016/
A little quote from there:

OS X itself has much more (exclusive) features than an Unix-like OS or a 100% Unix certified OS needs and I don't think that strict Unix conformity is a must. But depending on who you ask you will get different opinions about this.

One major issue with OS X is that the included GPL software is stuck with its last GPLv2 licensed version. Some of them are 5 or 6 years old and totally outdated. Even the conservative distros (RHEL, SLES, Debian stable) have newer GPL-bits than OS X.
Apple has to change its views about GPLv3 licensed software OR it should replace all outdated GPLv2 programs with their own solutions. (For example with BSD licensed counterparts)
But currently the world within Terminal.app/iTerm2.app has started to smell and this won't get better if Apple continues to do nothing.

 

UNIX is an OS, but a bear command line OS with some GUI capabilities. My analogy still applies given what OS X has done.

 

Was there ever a logo that incorporated both 'Darwin' and UNIX'?

Other logos that come to mind:

Because they already had Steve's baby Nextstep. Since he didn't have a time machine. He had to build Nextstep off of UNIX.

 

When Linus Torvalds created Linux, he wants to have UNIX running on affordable, commodity hardware. That's not what Steve Jobs had in mind when he introduced Mac line with OSX. What is more powerful? It's waste of time to argue. It's depended on what you do with it? As far as Servers, Linux is far more popular. But on the Desktop/Laptop, Linux is nothing compare to Windows or Mac. Windows is probably the least favor in this forum but they still by far the top percentage wise. It has the most software available. So, there is pointless on arguing which OS better. The question is which OS is better for you.

 

Neither does OS X.

----------

There is no "BSD UNIX" in OS X. It is based on the opensource BSDs.

----------

It's not "built from UNIX". It incorporates code from the opensource BSDs (which are NOT UNIX).

The only reason Apple are able to call OS X UNIX is because with 10.5 they made a few changes and paid the current UNIX IP holder (The Open Group) a couple of hundred thousand per year to call OS X UNIX.

For what it's worth: Apple used the 'UNIX BASED' logo for a while.
