XNU/Darwin

Kexts(Kernel Extensions) are XNUs equivalent to Loadable Kernel Modules in Linux. Much like Linux they are either loaded automatically at boot (in this case the Mac OSX unit is launchd and there’s a separate program that handles startup services loaded by launchd at boot called launchctl) or using the kextload command to start a kext file manually. As far as I am aware kext files are not kernel specific like Linux kernel modules are. kexts can also just as easily be ran in user space

I remember being able to install a true multitasking windowing system on iOS 4 that was jailbroken but I don't think I can do that shit on modern devices

doesnt it require many nonstandard things to work? also the thing that they released is not really a usable os

The only real issue is lack of hardware support but AFAIK Darwin will run fine on any hardware setup that supports OSX wither that’s official or hackintosh

Apple devices are botnet. Probably that's the reason, people knowing about why software freedom matters don't invest their time in making Darwin usable.

Is there a way to use just its GUI on Linux? (By the way, it's no longer called OSX, now it's macOS.)

It's called Aqua and no, it's proprietary and depends on a number of proprietary components, most importantly Quartz Compositor.

It’s because the effort hasn’t been put in to port it to other hardware. Rewriting Linux modules into kext files is not a trivial process

He was wrong. By default Darwin has no GUI and just drops you into Bash

but can you rip it off a mac and use it

Not directly but someone did make a program to translate it to WebGL

God, why

I was about to say it was developed by Poos, but it was actually made by this guy

How come Apples Metal API generally performs better than Vulkan? It’s really hard to get an Apples to Apples (pardon the pun) comparison because Apple doesn’t officially support Vulkan (There is a third party Vulkan library that runs on Metal however) but my iPad Air 2 gets a significantly higher score on 3DMark then my Android phone using a snapdragon 820 SoC that should be faster using identical settings including resolution

apple stuff is probably so hardware specific that they can optimize it really well for them. cant really do that when your shit has to run on thousands different devices.

Metal and Vulkan both support the same GPUs on paper. Yet somehow Apple was able to reduce the overhead and improve parallelism of their API

iOS 10 had a tweak called Empoleon for multi window, it was free too.

Sage for off topic

iOS 12 has native multi windowed multitasking but I think it’s limited to just windows at a given time

*3 windows

XNU is an example of the UNIX Philosophy done right when put into competent hands. The core design of XNU is robust enough that Apple can basically strip out or add as much shit as they want and optimize it as much as they want without even having to touch the kernel for the most part. You never hear Apple ever talking about their kernel tech, which is a good thing, it’s something that you shouldn’t have to ever need to bring up. Compare that with Linux autism

This, plus no (((systemd)))

XNU is a microkernel while Linux is a monolithic full feature kernel. I would be worried if the XNU microkernel would require year after year of updating because microkernels are supposed to feature an small upper limit to its featureset. I don't share the same concern for Linux because it is a monolithic kernel with all the features of what we demand for a contemporary monolithic kernel.

So in other words you're saying monolithic kernels are trash

Monolithic kernels are nothing but ‘contemporary’ and GNU/Linux is the only trash still using this paradigm. Modern iOS/Mac OS is essentially Apple finally able to realize what Workplace OS and Taligent failed to do in the 1990s.

I wasn't referring to the thought of monolithic kernels being a new contemporary idea. I was referring to the kind of full featured monolithic kernels that people use in their computers today.

I know right?
There's this project called Darling that's basically the same thing for MacOS what WINE is for Windows Applications. It basically lets you run MacOS software on Linux.

In hindsight, it should be much easier to optimise and integrate since Darwin is basically BSD with old microkernels on top. But ironically it's not...
It's been 7 Years, and it's still Terminal Only. It can barely run GUI Applications.
I can't tell if this is Apple's doing, or if MacOS is much more Closed-Source than we think. But it's a bit painful to say the least...

What do you think?

doesnt windows have quite good documentation. apple probably doesnt since its systems are only meant to be used on their own hardware so they dont need to release anything

Is there a way I can make my ipad 2 A1395 look like that?

It’s not that simple. Darwin is a lot less BSD-Like then BSDfags think. The BSD heritage mostly comes from its fork of Mach hiding deep within XNU and some superficial UNIX related things. Darwin is its own beast. The executable format isn’t even the same. Darwin uses Mach-O while BSD uses ELF like Linux

All Mac OS applications rely on Cocoa and the Quartz compositor which are both closed source and is what OSX uses for all GUI elements and the display server

Darwins kernel and core libraries are open source and derived from NextSTEP while the user mode APIs and GUI subsystems are all proprietary. The open source shit has been reimplemented just fine, it’s just the proprietary Apple-specific bits that have been slow to implement. Luckily the Darwin side is still being maintained by Apple even if it is only available as source code

Jailbreak and install Quasar from Cydia modern iPads with modern iOS versions have native windowed multitasking as well out of the box

You guys talk too much about what you think is, but don't go after any source whatsoever.
Here's a more technical view about XNU:
osxbook.com/book/bonus/ancient/whatismacosx/arch_xnu.html

A highlight:
So XNU is a monolithic kernel with some micro kernel abstraction built-in. There's no such a thing as a hybrid kernel. Either is Monolithic or micro.

BSDs role in XNU is greatly oversold. They can rewrite the sockets and IPC related shit from scratch and the rest of the system wouldn’t care or notice let along the programmer
The problem with this sentiment Linus is it really makes no sense calling XNU a monolithic kernel. Following the same logic you really can’t say microkernels exist either. All kernels are ‘monolithic’ to a degree

I've already jailbroken, but apt repos for my version seem to be dead. Guess I have to host one myself and compile everything.

Have anyone tried this? How you know this statement is true?

A micro-kernel is a kernel that you get by removing all non essential features, if you remove anything else, the system falls apart.
For instance, SeL4 is, basically is:
sel4.systems/Info/Docs/seL4-manual-latest.pdf
So, clearly XNU is not a microkernel, but a monolithic one with microkernel-like facilities.

That is subjective. You can say the same thing about Linux on certain distros. To me the difference between microkernels and monolithic is down to kernel-level modularity. Generally speaking the core components of Linux are tied down by dependencies to the point kernel modules have to be tied to specific kernel versions. Microkernels generally don't have issues like that, so in that sense I think XNU counts as a microkernel

Yeah there is still a tweak for iOS11-iOS12 and it's called MilkyWay. Looks almost exactly like your pic

Doesn’t iOS 12 on iPad already have native multiwindowed multitasking?

No idea. I don't own an iPad. Just an iPhone XS Max right now. And that tweak is what I use.

It's called hybrid kernel, retard.
