Summary: From this post, you will learn a list of Mac OS versions from the latest to the oldest. It emphasizes the features and defects of each Mac operating system version.

All Macos Versions

The Mac operating system(Mac OS) is the second most widely-used operating system targeted for Apple's Mac family of personal computers. It's praised for its straightforward graphical interface and high security but criticized for updating problems and hardware limitations. We will walk you through the Mac operating systems list in three categories - macOS, OS X, and Mac OS X, starting from the latest Mac OS - macOS Monterey.

All macOS versions

Apple changed the name 'OS X' to 'macOS' in 2016, adopting the nomenclature they were using for their other OSes, iOS, watchOS, and tvOS. As the latest series of Mac operating systems, let's check the list of macOS versions and see what's new here.

macOS 12 Monterey

macOS Monterey, the latest release on the list of Mac OS versions, is officially launched on October 25, 2021. It is an incremental upgrade from the already-polished macOS Big Sur, focusing on transiting apps on iPhones and iPads to Mac. One significant feature of this update is that people can create links to FaceTime calls to share with other Mac users and, for the first time, with Android and Windows users.

Another neat feature that pops up on FaceTime, which outperforms competitors like Zoom, is SharePlay. It allows people to watch or listen to streaming content by syncing each's video and playback controls. The Messages app has a new "Share with You" feature that can reveal the contents you've received in Messages in the relevant app, which applies to the Apple TV app, Photos, Safari, Apple Podcasts, etc.

Other changes include Live Text and Shortcuts. Apple's search engine - Safari, is also improved to allow people to open and close entire tab groups as needed quickly. However, the headline-grabber is probably Universal Control, allowing people to control multiple Apple devices with a single mouse and keyboard.

These macOS 12 powerful features intrigue people to upgrade. But it's not compatible with every Mac model (only compatible with MacBook Air and MacBook Pro models released in early 2015 and later). Also, it doesn't support Macs featuring Nvidia Brand GPUs.

macOS 11 Big Sur

macOS 11 Big Sur was released on November 12, 2020, named after a coastal area in California. It is a step of cohering its user experience across Apple devices. iPhone and iPad users may feel newly familiar with Big Sur since the redesign adds up to an aesthetic that is closer to iOS.

macOS Big Sur update and Apple silicon transition that happened subsequently were two significant events in 2020. Big Sur is the first macOS for Macs powered by the M1 chips that natively run iOS and iPadOS applications. It also allows faster backups on APFS-based Time Machine.

The interface with full-height sidebars and refreshed Dock accommodating uniform square icons with rounded edges display its main design change. Safari, Maps, and Messages are all updated with useful new features such as providing guides that allow you to discover new palaces to explore and cycling directions that you can send to your iPhone.

Moreover, the Control Center that we enjoyed for years on iPhones is finally on Macs. You can now access the controls you use most such as Bluetooth, Wi-Fi, AirDrop controls, Do not Disturb, and more, with a simple click on the Control Center button from the menu bar. Unfortunately, Big Sur dropped support for some Macs released in 2012 and 2013.

macOS Big Sur

macOS 10.15 Catalina

Released in 2019, macOS Catalina comes with three striking new apps: Apple Music, Apple TV, and Apple Podcasts. These three apps provide you with beautiful songs, fantastic movies and TV shows, and exciting radio broadcasts. What's more, tired of switching from your iPad to MacBook? Don't worry! Catalina now can create Mac apps from the iPad apps you run for daily use. This design connects your iPad and MacBook, which achieves the integration of the Mac operating system.

Catalina also brings some problems. First, it is incompatible with MacBook Air and Pros before 2012. Second, Catalina ends the support for 32-bit applications. You'll have to find replacements for these apps if you still want to run them with the macOS Catalina. Third, just like its predecessor, Mojave, the enhanced security of Catalina keeps requiring you to confirm to run certain apps.

macOS Catalina

macOS 10.14 Mojave

Apple released macOS 10.14 Mojave on June 4, 2018, with new features including the brilliant introduction of dark mode, which is refreshing for users, image-management features built into QuickLook, a more informative App Store, etc.

macOS Mojave also has its flaws. With increased security measures, the user has to give apps permission to do things they've been doing all along, which can be annoying. Also, every new macOS may face incompatibility with previous software, which could cause data loss after updating to macOS Mojave.

macOS Mojave

macOS 10.12 Sierra and macOS 10.13 High Sierra

macOS 10.12 Sierra is the first one on the list of macOS versions receiving the name change from California's landmark to its coastal areas. Released in 2016, the new features of macOS 10.12 Sierra include the addition of Siri, optimized storage, and updates to Photos, Messages, and iTunes. The introduction of Siri can be a ground-breaking design for Mac operating system. With the help of Siri, we can quickly find the documents and get access to the file without wasting too much time.

macOS 10.13 High Sierra was released one year later. Like OS X El Capitan and OS X Mountain Lion, this OS is also a refinement-based update having very few new features. Nevertheless, sometimes it's the small change that makes a big difference. The highlight of this version is the use of the new Apple File System(APFS), which changes how data is stored and organized.

macOS High Sierra

Now, you know all versions of macOS until 2022 with their highlights and shortcomings. Read on to discover the older versions of Mac operating systems.

OS X versions

Apple shortened the name 'Mac OS X' to 'OS X' in 2012 and switched to landmarks in California to name operating systems since OS X 10.9 Mavericks. Here, we will explain all the OS X versions to 

OS X 10.11 El Capitan

Released in 2015, instead of introducing significant changes, Apple described OS X 10.11 El Capitan as containing 'refinements to the Mac experience' and 'improvements to system performance' rather than new features. OS X 10.11 El Capitan offers battery and speed improvements, improved language support, and mission control for its pros. Separate windows make it more convenient for users to switch from one to another.

As for the cons, though El Capitan has enhanced security, however, you can't have your cake and eat it. Because of the enhanced security, some functions don't work anymore. For example, new security features in El Capitan prevent some free utilities from changing default folder icons, and the old paste-into-Get-Info method doesn't work either.

OS X El Capitan

OS X 10.10 Yosemite

Released in 2014, Yosemite features a redesigned user interface similar to that of iOS 7. It also features the new concept 'handoff,' enabling users with iPhones running iOS 8.1 or later to answer phone calls, receive and send SMS messages, and complete unfinished iPhone emails on their Mac. These features bridge the gap between the computer and the smartphone.

As for its weaknesses, first, the system font won't likely cater to everyone's taste. Second, notifications can pile up and may drive you crazy if loads of things are waiting to be done.

OS X Yosemite

OS X 10.9 Mavericks

Released in 2013, the highlight of Mavericks was that it was a free upgrade to all users running Snow Leopard or later with a 64-bit Intel processor. The changes of Mavericks included the addition of the previously iOS-only Maps and iBooks applications, improvements to the Notification Center, and many under-the-hood improvements.

For its cons, though you can see the links shared by others with the revamped Safari, shared links in Safari don't support Facebook, and you might feel offended if you are a Facebook lover. Also, though Mavericks tries to fulfill the target of multitasking, it still feels limited when you run the computer.

OS X Maverics

OS X 10.8 Mountain Lion

Since the release of Mountain Lion in 2012, Apple started to offer new releases of the Mac operating system on an annual basis as its iOS updates. Critics praised the new Notification Center, Messages, and speed improvements but condemned the unreliable iCloud and Game center lacking games.

It's worth mentioning that Mountain Lion introduced more Chinese features, including support for Baidu as an option for Safari search engine, QQ, 163.com, and 126.com services for Mail, etc. AirPlay Mirroring is an exciting feature borrowed from iOS, but it supports only a subset of Macs compatible with Mountain Lion.

OS X Mountain Lion

Mac OS X list

The first desktop version of the Mac OS X operating systems was Mac OS X 10.0, released in March 2001. Except for the first Mac OS X beta, Apple named all Mac OS X series versions and OS X 10.8 after big cats from Cheetah to Mountain Lion. Here, we will introduce the last two legendary releases in the Mac OS X list that are still in use.

Mac OS X 10.7 Lion

In 2011, Mac OS X 10.7 Lion presented Apple's first step to bring iOS concepts to Macs. For example, reverse scrolling and auto-hiding Scroll bars that disappear when not in use. It also introduced an easily navigable display of installed applications called Launchpad and, more importantly, documents auto-save by default. You don't have to struggle for the unsaved documents anymore!

Apple has allowed free downloads of Mac OS X Lion since June 2021. Nevertheless, Many minor modifications, including gestures, scrolling direction, visibility, and different way of resizing windows, may frustrate long-term Mac users. And it abandoned Mac OS X software written for the PowerPC processor that works fine with Snow Leopard.

Mac OS X Lion

Mac OS X 10.6 Snow Leopard

Released in 2009, Snow Leopard meant to be a refinement for its predecessor, Leopard.

Most of its changes, such as rewriting the Finder application, are not intended for users to see. Therefore, users may experience few changes in the user interface. It received positive feedback for its low price and increased performance and efficiency.

However, like Leopard, Snow Leopard does not support macOS 9/Classic software at all. The release of Snow Leopard also marked the switch of distribution from the optical disc to the App Store.

Mac OS X Snow Leopard

Which Mac operating system is the best so far?

The answer to this question may vary from case to case. Generally speaking, the best macOS version is the latest one that your Mac is eligible to upgrade to. There are a couple of reasons for that conclusion:

  • Apple updates OSes annually with improved features and better security. The latest version is more likely to save you from bugs older versions can't fix. 
  • As App developers update their products, older versions of operating systems will roll off the supporting matrix. If your OS is incompatible with the upgraded apps, you may find yourself stuck with the old ones.

However, if you need to run some legacy apps on Mac, Mojave is the final version of macOS to support 32-bit software.

How to know if an app is 32-bit or 64-bit?

Steps to check if an application is 32-bit or 64-bit on macOS:

  1. Click the Apple logo > About This Mac > System Report.
  2. Under the Software tab, choose Applications.
  3. Select the app in question.

The information you see varies on different macOS.

On macOS Mojave and earlier:

Under the 64-Bit (Intel) column, you can see the word Yes and No used to indicate an app's architecture.

Yes: 64-bit

No: 32-bit

On macOS Catalina and later:

Since Apple stops the support for 32-bit apps from macOS Catalina, all applications running on Mac are 64-bit. So instead of showing 32-bit or 64-bit, it tells you whether the app is optimized for Intel or M1 Mac, etc.

In the Kind column, you will find five types of apps:

Universal: Run on Intel and M1 Macs

Intel: Only for Intel Macs

Apple Silicon: Only for M1 Macs

iOS: iPhone and iPad apps available on Apple Silicon Macs

Other: For others

If you want to run some old 32-bit apps, you will need to downgrade your current macOS to macOS Mojave.

Which macOS should you use?

After viewing the list of Mac operating systems, you may be curious about which macOS you should use. A quick answer to that is the latest version of macOS your Mac supports because it gives you the best security or features your current Mac models can receive. If you are not running the newest available OS to your Mac models, consider updating macOS.

Apple releases a new version of macOS yearly, but not every Mac models are able to benefit from it. Currently, Apple provides security patches and software maintenance for the latest macOS (macOS Monterey) and the previous two major releases (Big Sur and Catalina).
