Mac OS X & macOS version code names
The Mac OS is in a.zip format so you will need to extract the file first. The reason why we uploaded this here is to keep everything in one location. I will be uploading some older versions of Mac OS suitable for older macbooks here. Lets get on with the Mac OS Sierra Download. The latest macOS version, macOS Catalina, was announced at Apple’s WWDC Conference on June, 3rd 2019 and now it's available for everyone to download. Here’s everything you need to know about the latest Mac operating system.
macOS was previously known as Mac OS X and later OS X.
Apple’s macOS High Sierra (aka macOS 10.13) is the newest version of Apple’s Mac and MacBook operating system. The latest update to be issued to High Sierra is version 10.13.4.
macOS and OS X version code-names
For example, in May 2018, the latest release of macOS was macOS 10.13 High Sierra. This release is supported with security updates, and the previous releases—macOS 10.12 Sierra and OS X 10.11 El Capitan—were also supported. When Apple releases macOS 10.14, OS X 10.11 El Capitan will very likely no longer be supported.
The latest version is macOS Mojave, which was publicly released in September 2018. UNIX 03 certification was achieved for the Intel version of Mac OS X 10.5 Leopard and all releases from Mac OS X 10.6 Snow Leopard up to the current version also have UNIX 03 certification.
How to download and install macOS updates
Apple’s macOS High Sierra update is free to all users and there is no expiration on the free upgrade, so you don’t need to be in a rush to install it. Most apps and services will work on macOS Sierra for at least another year. While some are already updated for macOS High Sierra, others are still not quite ready.
Now that Apple has updated the Mac App Store in macOS Mojave, there is no longer a Purchased tab. To reiterate, it is possible to download the installer for an older versions the Mac App Store but only if you are running macOS High Sierra or older. If you are running macOS Mojave this will not be possible.
macOS High Sierra is well worth the upgrade. MacOS High Sierra was never meant to be truly transformative. But with High Sierra officially launching today, it’s worth highlighting the handful of notable features.
First, click on the Apple icon in the top left corner of your screen. From there, you can click ‘About this Mac’. Keyboard for mac and pc. You’ll now see a window in the middle of your screen with information about the Mac you’re using. As you can see, our Mac is running OS X Yosemite, which is version 10.10.3.
If you have hardware or software that isn’t compatible with macOS Sierra, you might be able to install the previous version, OS X El Capitan. macOS Sierra won’t install on top of a later version of macOS, but you can erase your disk first or install on another disk.
OS X Mavericks (version 10.9) is the tenth major release of OS X (since June 2016 rebranded as macOS), Apple Inc.’s desktop and server operating system for Macintosh computers.
If you have a computer running El Capitan still I highly recommend you upgrade to a newer version if possible, or retire your computer if it cannot be upgraded. As security holes are found, Apple will no longer patch El Capitan. For most people I would suggest upgrading to macOS Mojave if your Mac supports it.
If you have macOS Sierra (the current macOS version), you can upgrade straight to High Sierra without doing any other software installations. If you are running Lion (version 10.7.5), Mountain Lion, Mavericks, Yosemite, or El Capitan, you can upgrade directly from one of those versions to Sierra.
Bottom line is, if you want your system running smoothly for longer than a few months after the installation, you’ll need third-party Mac cleaners for both El Capitan and Sierra.

Cupertino, California — Apple today announced macOS High Sierra, the latest release of the world’s most advanced desktop operating system, is now available as a free update.
Wondering what the latest version of MacOS is? It is currently macOS 10.14 Mojave, although verison 10.14.1 arrived on 30 October and on 22 January 2019 version 10.14.3 bought some necessary security updates. Prior the launch of Mojave the most recent version of macOS was the macOS High Sierra 10.13.6 update.
I’ve been using Mac Software since Mac OS X Snow Leopard 10.6.8 and that OS X alone beats Windows for me.
And if I had to make a list, it would be this:
Apple revealed macOS 10.13 High Sierra at the WWDC 2017 keynote, which is no surprise, given Apple’s tradition of announcing the latest version of its Mac software at its annual developer event. The final build of macOS High Sierra, 10.13.6 is available right now.
High Sierra is far from Apple’s most exciting macOS update. But macOS is in good shape as a whole. It’s a solid, stable, functioning operating system, and Apple is setting it up to be in good shape for years to come. There are still a ton of places that need improvement — especially when it comes to Apple’s own apps.

New features that this update will bring to Mac is a battery health feature that is supposed to reduce the rate at which the device’s battery ages.

This feature can be turned on and off from System Preferences > Energy Saver.
Even though macOS Big Sur version beta 8 is out. In this next post, you will receive information about the latest final macOS version – macOS Catalina. We will tell you about the changes and improvements that have been brought to Mac with this newest operating system and we will also briefly mention some of the more notable features of previous macOS releases.
Additionally, you will learn how to check the current macOS version on your Mac as well as how to upgrade and downgrade it.
The latest operating system for Mac is called Catalina (mac OS version 10.15.5) and it is the sixteenth major upgrade for macOS. As of May 2020, it has become the current operating system for Mac computers. Its name is inspired by Santa Catalina Island, an island located in California’s Channel.
Notable changes made with macOS Catalina are the removal of iTunes, the addition of the Sidecar feature, the expansion of the iPhone and iPad Screen Time featureto Mac computers, and others. Additionally, significant changes have also been made to the macOS security. Below, we will have a quick look at each of these improvements:
The CPU and TurboBoost function have been both optimized for an increased battery life. It works by shutting off CPU cores but allowing for a higher frequency rate on working cores to sustain performance.
iTunes has been a part of Mac computers ever since 2001 but with Catalina, it has officially been terminated. Now, with the latest macOS release, instead of iTunes, users will have access to three separate apps that together take over the functions of iTunes. Those apps are Music, TV, and Podcasts.
As for managing your devices, with Catalina, this is done via Finder and not via an app.
This feature allows Mac users who also own an iPad to turn their iPads into second screens for their Mac computers. The Mac screen could be extended to the iPad or they could both show the same content (mirror screen). Sidecar also works with Apple pen, enabling users to use their iPads as drawing tablets.
This is an iPhone and iPad feature that, with Catalina, has been carried over to Mac computers. Screen Time allows you to track the usage of all your Apple devices, providing useful information on how your time is being spent across them.
The Find My app implements the Find My Mac and Find my Friends technology to provide users with the ability to potentially find their lost/stolen device. This technology does this by employing Bluetooth and the help of other devices that are near the lost/stolen one.
One of the biggest changes made that came with Catalina is related to the security of the macOS.
The first improvement is the Read-Only system volume – a dedicated system volume that allows Catalina to run separately from other data, thereby preventing any potential attempts at tampering with system files done by malware and hackers.
Next, the Gatekeeperfeature, which previously only used to check the sources of new apps, now also checks the apps themselves and prevents them from running if it deems them potentially unsafe.
Thirdly, unlike earlier macOS releases, Catalina requires explicit user approval if an app wants to access data stored in the Desktop, Downloads, and Documents folder. Only after the user gives their permission would the app be able to gain access to such data.
One other notable change is that 32-bit apps can no longer be run on Mac computers if the latter have been updated to Catalina, making macOS Mojave the last macOS release that supports 32-bit apps.
In this section of the article, we will briefly go over the older macOS releases and the most notable changes they’ve introduced, starting with the leaser recent one:
Yosemite overhauled macOS’s user interface and introduced the Continuity and Handoff features which improved and expanded pairing between iOS and macOS devices. Receiving phone calls and text messages was now possible on either device and so was editing same documents across devices.
Later on, a Yosemite update replaced Aperture and iPhoto with Photos.
This macOS release was focused on system performance improvements and changes to already existing features. Public transport information was made available in the Mapsapp, the Notesapp received interface improvements, and the Metal API performance-enhancing app was officially introduced to macOS.
Sierra brought Siri to Mac computers and added several Mac-exclusive features for the app. Improvements were also made to the iCloudapp, which could now store user data from the Desktopand Documentsfolders, allowing syncing of those folders with other Macs that share an Apple ID. Additionally, Sierra website support for Apple Pay through the use of a nearby Touch ID or iOS device for authentication.
Most improvements here were “under-the-hood” – High Sierra brought improvements to VR support, as well as to apps such as Safari, Spotlight, Notes, and Photos. High Sierra was the first to start using Apple File Systemand it also introduced the successor to the Metal API performance-enhancement application – Metal 2.
New features introduced by Mojavewere the Dynamic Desktop, Desktop Stack, and Dark Mode. Several iOS-exclusive apps such as Home, Apple News, and Voice Memoswere also carried over to macOS.
