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.
The best Mac OS version is the one that your Mac is eligible to upgrade to. In 2020 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
To find out which macOS is currently running on your Mac, follow these steps:
- Click on Apple logo in the top left corner of the menubar
- In the dropdown click on the first item: About This Mac
- 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.
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:
- Click on Apple logo in the top left corner of the Mac screen
- Click on About This Mac option
- Click on System Report button in Overview tab (first one)
- Scroll down to Software -> Applications
- 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.
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.

Mac Os Mavericks Installer
What you need to create a bootable installer
- A USB flash drive or other secondary volume, formatted as Mac OS Extended, with at least 12GB of available storage
- A downloaded installer for macOS Big Sur, Catalina, Mojave, High Sierra, or El Capitan
Download macOS
- Download: macOS Big Sur, macOS Catalina, macOS Mojave, or macOS High Sierra
These download to your Applications folder as an app named Install macOS [version name]. If the installer opens after downloading, quit it without continuing installation. To get the correct installer, download from a Mac that is using macOS Sierra 10.12.5 or later, or El Capitan 10.11.6. Enterprise administrators, please download from Apple, not a locally hosted software-update server. - Download: OS X El Capitan
This downloads as a disk image named InstallMacOSX.dmg. On a Mac that is compatible with El Capitan, open the disk image and run the installer within, named InstallMacOSX.pkg. It installs an app named Install OS X El Capitan into your Applications folder. You will create the bootable installer from this app, not from the disk image or .pkg installer.
Use the 'createinstallmedia' command in Terminal
- Connect the USB flash drive or other volume that you're using for the bootable installer.
- Open Terminal, which is in the Utilities folder of your Applications folder.
- Type or paste one of the following commands in Terminal. These assume that the installer is in your Applications folder, and MyVolume is the name of the USB flash drive or other volume you're using. If it has a different name, replace
MyVolumein these commands with the name of your volume.
Big Sur:*
Catalina:*
Mojave:*
High Sierra:*
El Capitan:
* If your Mac is using macOS Sierra or earlier, include the --applicationpath argument and installer path, similar to the way this is done in the command for El Capitan.
After typing the command:
- Press Return to enter the command.
- When prompted, type your administrator password and press Return again. Terminal doesn't show any characters as you type your password.
- When prompted, type
Yto confirm that you want to erase the volume, then press Return. Terminal shows the progress as the volume is erased. - After the volume is erased, you may see an alert that Terminal would like to access files on a removable volume. Click OK to allow the copy to proceed.
- When Terminal says that it's done, the volume will have the same name as the installer you downloaded, such as Install macOS Big Sur. You can now quit Terminal and eject the volume.
Use the bootable installer
Determine whether you're using a Mac with Apple silicon, then follow the appropriate steps:
Mac Os X Mavericks Installer
Apple silicon
- Plug the bootable installer into a Mac that is connected to the internet and compatible with the version of macOS you're installing.
- Turn on your Mac and continue to hold the power button until you see the startup options window, which shows your bootable volumes and a gear icon labled Options.
- Select the volume containing the bootable installer, then click Continue.
- When the macOS installer opens, follow the onscreen instructions.
Intel processor
- Plug the bootable installer into a Mac that is connected to the internet and compatible with the version of macOS you're installing.
- Press and hold the Option (Alt) ⌥ key immediately after turning on or restarting your Mac.
- Release the Option key when you see a dark screen showing your bootable volumes.
- Select the volume containing the bootable installer. Then click the up arrow or press Return.
If you can't start up from the bootable installer, make sure that the External Boot setting in Startup Security Utility is set to allow booting from external media. - Choose your language, if prompted.
- Select Install macOS (or Install OS X) from the Utilities window, then click Continue and follow the onscreen instructions.

For more information about the createinstallmedia command and the arguments that you can use with it, make sure that the macOS installer is in your Applications folder, then enter the appropriate path in Terminal:
- Big Sur: /Applications/Install macOS Big Sur.app/Contents/Resources/createinstallmedia
- Catalina: /Applications/Install macOS Catalina.app/Contents/Resources/createinstallmedia
- Mojave: /Applications/Install macOS Mojave.app/Contents/Resources/createinstallmedia
- High Sierra: /Applications/Install macOS High Sierra.app/Contents/Resources/createinstallmedia
- El Capitan: /Applications/Install OS X El Capitan.app/Contents/Resources/createinstallmedia
A bootable installer doesn't download macOS from the internet, but it does require an internet connection to get firmware and other information specific to the Mac model.
