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.

The best Mac OS version is the one that your Mac is eligible to upgrade to. In 2021 it is macOS Big Sur. However, for users that need to run 32-bit apps on Mac, the best macOS is Mojave. Also, older Macs would benefit if upgraded at least to macOS Sierra for which Apple still releases security patches.

How to Tell Which macOS You Are Running

Easily check which versions of mac OS, iOS, iPadOS, or watchOS are compatible with your Mac model or iDevice. Guide includes OS X 10.8.x to macOS 11.0.x. Since the arrival of the Mac App Store in 2011 (as an update to Snow Leopard) versions of Mac OS X and macOS have been available to download via the Mac App Store. However, that changed slightly.

To find out which macOS is currently running on your Mac, follow these steps:

  1. Click on Apple logo in the top left corner of the menubar
  2. In the dropdown click on the first item: About This Mac
  3. The first line in the Overview tab is the name of the current OS.

What Version of OS Can My Mac Run?

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.

Which OS is Best for my Mac

Anytime someone asks me which OS is best for them I always suggested going with the latest. Things have changed recently, however.

Should I Upgrade to macOS Catalina or Big Sur?

While personally I like macOS Big Sur and have it installed on my MacBook Pro, it comes with serious breaking changes.

Most Recent Version Of Macos

The first issue is compatibility.

Big Sur is a transition OS which is designed to help Apple to move from Intel processors to their own chips on ARM.

After I installed Big Sur on my MacBook Pro mid 2020 (pre-Silicon), most of my apps, including Microsoft Office, were working as expected.

However, my VMWare Fusion 11 does not start anymore, so I have to purchase a new license if I want to keep using it (or roll back to Catalina). Luckily, I took a full backup before the upgrade.

The second breaking issue is the lack of 32-bit app support.

macOS Catalina and Big Sur can only run 64-bit apps.

If you wondering whether you should upgrade to macOS Catalina or Big Sur, 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 the upgrade.

For instance, I had to remove uTorrent after upgrade. And I didn’t know that uTorrent is 32-bit!

How to Know If App is 32-bit or 64-bit

To find out whether the app on your Mac is 32-bit or 64-bit follow these steps:

  1. Click on Apple logo in the top left corner of the Mac screen
  2. Click on About This Mac option
  3. Click on System Report button in Overview tab (first one)
  4. Scroll down to Software -> Applications
  5. Find the app and check Kind

Which macOS Should I Use

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 (or better High Sierra) for the following reasons:

  • Sierra is still supported by Apple, and it gets security updates
  • APFS file system is available
  • It supports Siri
  • Significant security improvements

The most important point when choosing the best OS is the ability to get 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.

Snow Leopard Myth

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.

How to Update to the Latest Version

There are two ways to update to the latest OS version on Mac:

  • From the Software Update section in System Preferences
  • Use a download link

Using Software Update

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.

If you are having problems with updates or having issues post-upgrade check my post about troubleshooting macOS.

Using download links

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.

If your computer is running macOS 10.13 High Sierra or older, it will need to be updated or replaced to continue receiving security updates, as well as updates and new features for commonly used applications (such as the Microsoft Office 365 suite and Teams).

Apple only officially supports the three most recent versions of macOS (currently 10.14 Mojave, 10.15 Catalina, and 11 Big Sur).

If you’re running an older version of macOS, it is no longer receiving security or stability updates. Running out-of-date, unpatched software, including operating systems, puts your data and the university at increased risk, and the university may restrict network access for devices running unsupported operating systems.

  • Further reading —Apple security updates

All UVM-owned computers running macOS 10.13 High Sierra or older must be updated or replaced as soon as possible to comply with the University Information Security Policy.

Which macOS version is installed?

  1. From the Apple menu in the top left corner of your screen, choose About This Mac.
  2. You’ll see the macOS name and version number, such as macOS Catalina 10.15.5; as well as your computer model and year.
  3. If your computer is running macOS High Sierra 10.13 or older it will need to be upgraded – make a note of your installed macOS version and your computer’s model and year as that information will be helpful when upgrading macOS.

Can my computer run a newer OS?

If you are running macOS 10.11 or newer, you should be able to upgrade to at least macOS 10.15 Catalina.

If you are running an older OS, you can look at the hardware requirements for the currently supported versions of macOS to see if your computer is capable of running them:

If your computer does not meet the minimum requirements for Catalina or Mojave, you will not be able to install a supported version of macOS. If this is the case, you will need to replace your current computer with a newer model.

How to upgrade macOS

The process of upgrading your computer varies depending on which version of macOS is currently installed on your computer.

Back up your data!

While data loss is relatively rare when upgrading macOS, it is best practice to backup your data via Time Machine or OneDrive before continuing.

Software Compatibility

Most Recent Version Of Macos Update

As of 10.15 Catalina, macOS does not support 32-bit applications. If you are upgrading from an older version of macOS, you may need to also upgrade some of the applications installed on your computer.

Upgrade from macOS 10.11 or newer

If you are running macOS 10.11 or newer, you should be able to upgrade to at least macOS 10.15 Catalina. To see if your computer can run macOS 11 Big Sure, check Apple’s compatibility info and installation instructions.

Faculty, Staff, and Employees should contact their IT support unit. If you do not know who your IT Support Provider is, please use the IT Lookup Toolto locate the appropriate support resource for your department.

Known Issues with Unsupported macOS

Known issues related to running unsupported macOS versions on your computer:

Apple only supports the three most recent versions of its macOS operating system – this means many software developers will only release feature and security updates to devices that are running a supported version of macOS.

Most Recent Version Of Macos X

Running an unsupported version of macOS may limit access to features and collaboration tools in Microsoft Teams (such as breakout rooms) and Microsoft Office products.

The macOS operating system has root certificates built into it that allow your browser and other applications to validate the various websites and servers your computer connects to. This establishes a chain of trust that helps to prevent malicious actors from posing as legitimate websites.

Most Current Version Of Macos Catalina

Unsupported versions of macOS receive the “Your connection is not private” error because the root certificate that was used to vouch for UVM sites expired on May 30, 2020. The new root certificate used to validate connections to most uvm.edu sites is not included in macOS versions 10.11 or lower, which is why those systems can’t establish a chain of trust.

This issue can be resolved by upgrading your macOS version to 10.14 or higher using the steps above.
