Welcome back. It's been a while.So this is the video that I've not been looking forward to making, to be honest.But we'll go ahead and we'll do it anyway.Mac OS and FreeBSD.They share a history, a lineage.Let's have a look at that today,huh, FreeBSDand Mac OS, they are very similar.They're both Well, Mac OSis a Unix certified OS,FreeBSD is a Unix like, but they, they share common lineage.So we have a look at that today andlet's dive in and have a look.So looking at Wikipedia, it will give you a lot of details on Mac OS.We're going to concentrate on Mac OS ten, Mac OS x, I'm pretty sure it'sMac OS ten, not X, but we're not going to start a war over that.So Mac OS ten first came out in99 as Mac OS ten, server1.0 and there were a lot of tools in thatin the operating system that come over from the BSD lineage.So we'll have a look at that.So there we go.As a result of next computer, next step was based on the MAC kernel developed CMU.Carnegie Mellon and BSD. Yeah, look at that.An implementation of Unix dating back to the seventies.So there we go.That's pretty much the history of it, to be honest.So let's have a look at the diagram and see what we get.So let's look at Mac OS where Ah yeah, there it is.Third one in.So what you'll notice there is a lot of the stufffrom Mac OS went into free BSD and vice versa.Well isn't that interesting.Now from what I've seen from commit messages, it's fairlyevident that Apple do contribute to the free BSD source code.And that's a good thing.We like that.We like to see companies put in back.So that's that's a positive.Now, I'm pretty sure I haven't seen it written anywhere, but I'mpretty sure that Mac OS tenhas FreeBSDNetwork stack to say that it's the Mac kernelwith the free BSD base would be oversimplifying thingsbecause it's not as simple as that and there's a lot more to it.You'll find that things aren't quite the same.Let's get this out the way.We don't need that.And a quick look at my uni minus eight.So there you'll see it's the Darwin kernel,which is the name of the Mac kernel.Now, this particular Mac actually all the way down here on Catalina,so it's quite an old one goes back to 2019and 2020 is when Big Sur came out.So we can't really put anything newer on it.We can but it's a lot of faffing around and perhaps I'll do that at some point.So there you go.It's a 2010 Mac mini. It's an old one.Dual-Core with six gig memory six get cake.I just tried to puteight in it and it just started beeping at just did not like it.I will matched sticks of memory. Where is it?It's here somewhere.It was here.Maybe I'll put it back over there. Maybe I didn't.I haven't come back.But it was here.Disorganized desk anyway.So what do we know about it?Apart from the shares of lineage?To be honest, not a lot.You know, we we can.We can certainly look at next step,which was Steve Jobs's company in between Apple stints.Sure we all know that.And that was released primarilyfor the education market is supposed to be for workstations.But yeah, they were expensive.They were very expensive.So there we go.Next step based on the kernel developed.Blah, blah, blah and BSD and implementation of Unix featureobject oriented programing framework based on C languageand the environment is known today in the Mac world as Coco.Is it really did not know.That was interesting.Anyway, so afterthat happened,Apple went along and bought next step and hence Steve Jobs back.And we all know that story so we're not going to hash over that.Okay, Keep going down.I did not know that, though too.Or blimey, that would have been something else, wouldn't it?Imagine if they'd all be us instead of next step.That would have been quite an interesting way.I wonder how things would have been different.Would have been quite a strange world.We would have made them. However, they didn't.They purchase next and we got Mac OS ten and a lot of the stuff that's in Mac OSten can be traced directly back to next an open step, the beach ball,the spinning beach ball of death that was originally from next step.So there we go.There's all the versions we ran on.I will attempt to put Ventura on this is likeit can be done, might even do a video of that.Then I if there's any interest in that,let me know in the comments and sure is the light.Yes it would be interesting to see how it runs on this hardware.Probably badlybut is entirely possible.So there we goin theis funny because I always believedthat there was more free BSD in Mac OS than there actually is,is basically just a few utilities and a little bit more.Was it I mean this doesn't really go into much detail soyou know, I might find more informationabout it on our own here, see if we can find it.FreeBSD is just Mac OS without the good bits.I buy that there is a mess that Mac OS is about FreeBSD,but Mac OS is just free BSD with a pretty good gooey.The two operating systems do share a lot of code.For example, most of the use land utilities in the C library on mac OSare derived from free BSD versionsderived and are the same is not the same.So basically what that means isthey took the free BSD utilities and tinkered with themfor their own purposes, which the license permits of course, and that's great.And there we go.Let some of this code flow works in the other direction.For example, previously 9.1 and later include a C++stack and compiler that were eligible originally developedfor Mac OS major parts of the work done by Apple employees.Darwin, which consists of the new kernel.And now if you look at the you name you would have seen Xenu.There is so this is as we can see there, Darwin.Where were me.Yeah, Darwin which consists of the Xenu kernel.Okay.A driver model and POSIX compatibility for BSDcompatibility layer makes up part of Mac OS.So what you probably find is a lot of the main pages are BSD.So let's check that out.This two man and they make BSD general commandsso much of the use land not all much ofis in mac OS with dispatchlib C++ were written for mac OSand worked on free BSD before any other OS.I never thought I'd say this, but thank you Applefor the help of development of free BSD.I am not a lover of Apple products.I don't think they fit my needs so I don't use them.However, here we are.So yeah, lots of code sharedbetween the two addresses, different kernels,few other models that are different, the driver model and a few other bitsand in all honesty, you know, Mac OS is a polishedoperating system and it will suit some people of course.Otherwise, Apple wouldn't be the company they are.It's not for me.I'm happy with that decision.If you don't use Apple products, I'm sure you're happy with that.I've said it before.I'll say it again.Use what is right for you.Don't let anybody tell you not to listen to people say, Oh,you must use Apple for professional work and you must use Windows for game it.If it works for you, it works for you.It really is as simple as that.I've said it time and time again,and I'm sure there are people that are sick of me saying it.So there we go. That is essentially freebeasties relationship to Apple and Apple's relationshipis essentially FreeBSDrelationship to Mac OS and vice versa.A lot of code sharing.If you like this video, please do give it a thumbs up and share it around.Very happy for you to share everywhere and comment in the comments section below.We do have a discount.We do have a discord server. It is still going.It's very quiet a moment.Guys can get in there and mix it up and start chatting.As always, I will see you in the next video.Take care and have a lovely, lovely day.Bye bye.
