When you upgrade to macOS Catalina, you get more of everything you love about Mac. Experience dedicated apps for music, TV, and podcasts. Smart new features in the apps you use every day. And Sidecar, which lets you use iPad as a second Mac display. Best of all, upgrading is free and easy.
Apple’s marketing for the introduction of the Macintosh focused heavily on its operating system’s intuitive ease of use. Unlike virtually all other contemporary PCs, the Mac OS (initially designated simply System Software, with a version number appended) was graphically based. The latest version of OS X features an elegant design, includes enhancements to the apps you use most, and enables your Mac and iOS devices to work together in new ways. Learn more about OS X; Safari extensions are a great way for you to add new features to Safari. Built by developers, Safari extensions use the latest web technologies.
Mac computers with Metal-capable graphics processors (GPUs) can upgrade to macOS Catalina.
Before you upgrade, we recommend that you back up your Mac. Then, if your Mac is running OS X Mavericks 10.9 or later, you can upgrade directly to macOS Catalina.
Go to Software Update in System Preferences to find the macOS Catalina upgrade. Click Upgrade Now and follow the onscreen instructions to begin your upgrade. If you don’t have broadband access, you can upgrade your Mac at any Apple Store.
If you’re running High Sierra (10.13), Sierra (10.12), or El Capitan (10.11), upgrade to macOS Catalina from the App Store. If you’re running Lion (10.7) or Mountain Lion (10.8), you will need to upgrade to El Capitan (10.11) first. If you don’t have broadband access, you can upgrade your Mac at any Apple Store.

Which Mac operating system is the best is a topic of numerous debates among Apple fans.
Since the mission of this blog is to refute myths and legends around Macs, it’s time for me to provide my 2 cents about the issue on hand. While everything below is just my opinion, as a long-time Mac user and veteran software engineer, I hope my opinion worth something.
TLDR; The best Mac OS version is the one that your Mac is eligible to upgrade to. In 2019-2020 it is macOS Catalina. However, users that need to run 32-bit applications on Mac should not go with Catalina because it only supports 64-bit apps. Also, older Macs would benefit if upgraded at least to macOS Sierra because this is the earliest operating system for which Apple still releases security updates.
Update: On WWDC 2020 Apple announced a new macOS Big Sur, which is said to have the biggest UI redesign and the biggest Safari update. New Safari will run 50% faster than Chrome and use less battery. It also has new limitations: Big Sur will require at least MacBook Pro late 2013, MacBook Air 2013, and Mac Mini 2014 or later to run. Big Sur will be released in the fall of 2020.
To find out which macOS is currently running on your Mac, follow these steps:
Not all Macs can be upgraded to the latest OS version. For instance, old Macs powered by PowerPC CPUs cannot run OS intended for Intel-based computers. Also, some versions have hardware limitations.
For instance, Mojave cannot be installed on MacBook Pro earlier than Mid 2012 model.
Check below to know exactly what version of OS your Mac can run.
Anytime someone asks me which OS is best for them I always suggested going with the latest. Things have changed recently, however.
While personally I like macOS Catalina and have it installed on my MacBook Pro, Catalina comes with serious breaking changes. If you have old 32-bit apps, they will not run in the new OS. macOS Catalina and newer can only run 64-bit apps.
If you wondering whether you should upgrade to macOS Catalina, first verify that you don’t have any 32-bit apps. But first, take a back up, so you can go back in case something breaks after upgrade.
For instance, I had to remove uTorrent after upgrade. And I didn’t know that uTorrent is 32-bit!
To find out whether the app on your Mac is 32-bit or 64-bit follow these steps:
If you have an older Mac which is not eligible to upgrade with some latest software or hardware, I’d suggest upgrading at least to Sierra for the following reasons:
The most important point when choosing the best OS is the ability getting security updates. While Apple generally does not announce the OS end of life dates, it is possible to know when they stop releasing security updates from this page.
For instance, according to the page, the last security update for OS X Yosemite was released on September 12, 2017. The last update for OS X El Capitan was in July 2018, and Carnegie Mellon University confirmed that El Capitan’s end of life date was August 2018.
I know that some users on forums believe that the best OS version for Macs was Snow Leopard. But that is a myth. And I know how such myths get created.
Once I worked in the company, which was selling a 20-year old product. And customers were still using and didn’t want to switch to new versions, because the old one was rock solid.
I then talked to the engineer who worked on the project, and he revealed that the product was a total disaster when it was first deployed. Engineers had to work on-site for almost a year in order to fix all bugs.
After five or so years of polishing the product, it becomes virtually bug-free, and nobody now remembers how bad it was when it was first rolled out. A similar thing happened Snow Leopard, and it was recognized as best mac os version after some time.
There are two ways to update to the latest OS version on Mac:
This is by far the best option, but it only available if you have Yosemite, or later OS installed already. If you enabled automatic updates, then Mac will inform you that the next macOS is available.
Just open System Preferences, go to Software Update and click on the Upgrade Now button.
This method is also best if wondering how to check if you have the latest version of OS installed on your Mac. Only the version compatible with your hardware will appear here.
For instance, my the latest version for Mac Mini 2012 is Mojave, I can’t install anything newer than that.
For older systems or in case you need to downgrade, you have to download a standalone installer in DMG format. DMG stands for disk image, similar to ISO, just different formats.
After downloading the installer, just double click on it and follow instructions. Again, do not forget to take a backup before the upgrade.
Following is a high-level description of all Mac operating systems as early as Mountain Lion.
You can refer to those descriptions when deciding which operating system is best for your iMac, Mac Pro, Mac mini, or MacBook.
With each OS description, I included a list of Macs supported. However, you can use Mac OS compatibility checker for more detailed information.
