Linux distribution, also known as distro in short. It is an operating system that is built using the Linux kernel. You can picture it as having a desktop environment that can be installed in any computer terminal. If you think about it, most operating systems like Windows and Mac are licensed while Linux is free software that is widely distributed. It is comprised of an assortment of software, tools, and libraries that are packaged together to meet user capabilities.

Naruto Shippuden: Ultimate Ninja 5, known in Japan as, Naruto Shippuden: Narutimate Accel 2 (NARUTO－ナルト－ 疾風伝 ナルティメットアクセル2, Naruto Shippuden: Narutimetto Akuseru 2), is the fifth installment in the Ultimate Ninja series, and was released in Japan on December 20, 2007.It was released in Europe on November 27, 2009, and in Australia on December 3, 2009.
We all know that the macOS is an elegant operating system. However, in the later years, it seems to feel challenged to keep up with the latest needs. Linux distros have leveraged this opportunity to be able to become an alternative to macOS, delivering a more sharp, polished, and clean desktop experience.
PureOS
PureOS is an operating system developed by Purism. It is one of the latest technologies that carry a modern, user-friendly feel without compromising performance or consumer rights. It is more focused on delivering better privacy and security among users, making it attractive to use. It takes an aggressive stance by eliminating vulnerabilities on the hardware level that adds on to user confidence with the software.
PureOS is also adherent to the open-source policy that is more inclined to integrating applications that are also open-source and not proprietary owned. It also has a bootable feature that can be run from a USB or a removable device while carrying the same capabilities from the original desktop environment.
Solus
Solus is a stable Linux operating system that offers a wide selection of software applications. One of the key features of the product is the Budgie desktop environment that is simple and highly customizable for advanced users. It is a fast operating system that uses Gnome technologies and is simply well-built. With the Solus OS, you can infer that it brings the harmony of the Chrome OS and macOS – having a sleek, good-looking, and clean interface.
The Solus Budgie OS comes with a bundle of software applications that should already get you started. It is more for home computing where you can utilize innovative features such as the Notification Panel and Dark Mode. It is also a lightweight platform that should be quick to install and reliable to use. Although the Solus Linux Distribution is composed of a small support team, there is a fair amount of documentation available on the web to guide advanced users for a custom setup.
Elementary OS
The Elementary OS is probably one of the best-looking Linux distro available. It is very easy to use and excellent for beginners that wish to delve into the Linux world. It carries a style that is a tribute to Apple's macOS with a genius desktop environment called Pantheon. The Pantheon is based on Gnome technology. With the latest versions of the operating system, you can expect that it has improved core applications and a better login interface.
Although it seems to have limited apps available, it still comes with the basic productivity apps such as a web browser and email app. If you would need to install more programs, you can do this with the AppCenter. Please be aware though that in the AppCenter, there are paid apps that will be offered that are designed particularly for the operating system.
Despite looking much like a macOS, the Elementary OS has done some more serious work on top of it apart from the look n' feel. They are protective of their ecosystem, imposing strict guidelines to design apps for the environment. This helps ensure that consumers will continue getting high-quality updates and features that mix well with Elementary OS.
Enaturox Mac Os Catalina
Zorin OS
The Zorin OS is a Linux distro that is based on Ubuntu. Its prime objective is to offer an alternative for users for Windows and Mac. Zorin OS is a powerful, secure, and fast software that respects one's privacy. It does not log activities that can usually be tracked with Windows. One nice thing about this operating system is that it can support a classic Windows layout or the macOS depending on user preference. This reduces the learning curve to navigate around the environment.
When it comes to the software center, you can install commonly used proprietary applications and any other open-source applications. Apart from this, Zorin OS delivers a reliable performance that is even compatible with old hardware technologies. It has been a candidate for development, gaming, simulations, and media production because of its overall flexibility and capability.
Ubuntu Budgie
The Ubuntu Budgie is a branched-out version of the Ubuntu OS. It offers the same stability as the Ubuntu software but with an added improvement. It is a lightweight operating system comes with a streamlined interface and various features. It has raised the bar for rivals in delivering quality software that genuinely integrates usability in all its forms. From introduction, navigation, and performance, the Ubuntu Budgie consistently exudes elegance.
The basic features are in place to easily get you up to speed in using the platform. It is simple, advanced, and safe for getting things done. With a strong foundation, the Ubuntu Budgie has easily earned approval from experts in terms of reliability and community support.
Conclusion
The Linux Distros that we have discussed are those that closely resemble the macOS. You can use Rufus to install all of these operating systems. But beyond this Top 5 list, there are a few more operating systems that deserve some recognition too. Although they have not made it through the list, it is worth mentioning:
Backslash
The Backslash operating system is relatively a new OS with a macOS feel. It is built with KDE technologies with a comprehensive set of documentation to guide novice and experts in customization.
Pearl OS
The Pearl OS has Xfce as a desktop platform with an envisioned goal of establishing a development environment called PearlIDE. It offers a promising outlook for innovation and collaboration between a community that is engaged in improving the software.
The whole purpose of the BootROM and EFI phases is to get to load and run the macOS kernel and its extensions, which is what boot.efi, the 'OS X booter', finally does. Although boot.efi doesn't suddenly vanish, from here on it is very little needed.
Like so much of macOS, the kernel and its extensions started off simple, and just grew into the monstrously complex. It now includes systems and features such as the Platform Expert, Mach with its inter-process communication of messages and ports, IOKit, and a goodly chunk of BSD's Unix features too. As I'm not a kernel engineer, I won't attempt to go into this any further: chapter 2 of Jonathan Levin's *OS Internals, volume 1, and the promised Volume 2 are and will be excellent references.
The two important topics with respect to the boot process are IOKit and extensions.
In the previous article, I mentioned that one of the important tasks of boot.efi was to build the IODeviceTree, and when starting the kernel, to hand that information over. This is only the start, as the kernel and loaded extensions expand that into a catalogue of all the installed drivers for hardware and other devices, the IORegistry.

In the previous article, I mentioned that one of the important tasks of boot.efi was to build the IODeviceTree, and when starting the kernel, to hand that information over. This is only the start, as the kernel and loaded extensions expand that into a catalogue of all the installed drivers for hardware and other devices, the IORegistry.
It is the IORegistry which is actually displayed when you use the ioreg command in Terminal, rather than boot.efi's rather simpler IODeviceTree. If you need to look at this registry, study its formatting and selection options carefully using man ioreg: they are complex.
IOKit is remarkable, possibly unique, as it uses object-oriented principles in classes and overloading. Instead of each driver being entire within itself, it declares itself to be a member of a particular family, so letting a driver re-use all the code which it has inherited from that family class, and it only has to implement the functions which differ.
For all this ingenuity, IOKit is a world unto itself, as browsing any of Apple's (now archived) documentation will reveal: try what it optimistically calls IOKit Fundamentals for a starter.
The kernel has just grown and grown, but needs a great deal more to be able to run a modern Mac. Device drivers, security extensions, filesystem drivers, and all sorts of other fundamental sub-systems need to tack themselves onto the XNU kernel, and do so as kernel extensions (KEXTs, or just extensions). Depending on which version of macOS you're running, there are around 300 in the main macOS /System/Library/Extensions folder, and perhaps a dozen or more in the admin-accessible /Library/Extensions, according to the third-party hardware and other products which you may have installed.
Until High Sierra, Apple controlled extension development with special developer signatures, but macOS 10.13 introduced another level of protection: User Approved Kernel Extension loading. This changed again in macOS 10.13.4, which primarily affects sysadmins and is detailed here, and the whole system is explained here. Further details are also given here, although that Technical Note is already deemed obsolete.
In practice, macOS High Sierra may install new extensions in /Library/StagedExtensions/Applications as a non-executable stub application, which is then protected by SIP. This may in turn be used as the source from which to install the extension if permission is given. This can result in strange problems.
With so many extensions to be loaded at boot time, macOS has a much better way of coping with this: it builds an optimised and pre-linked version of the kernel with its extensions, which is then stored in /System/Library/PrelinkedKernels/prelinkedkernel, which is pointed to from its more traditional location of /System/Library/Caches/com.apple.kext.caches/Startup/kernelcache.
One disadvantage of using a kernelcache in this way is that the log no longer lists each extension as it is loaded, but bolts through the whole 28 MB or more of kernel plus extensions without that running commentary.
Enaturox Mac Os Update
It is also worth bearing in mind that, when macOS updates replace the kernel and/or extensions, one of the time-consuming steps following installation will be the rebuilding of the kernelcache.
Having travelled the journey from the Mac first powering up, to loading a prelinked kernel, there remains one unanswered question which I will try to tackle in the last article in this series: how do we determine which should be the startup disk and boot volume?
