Download macOS Big Sur

If you're using macOS Mojave or later, get macOS Big Sur via Software Update: Choose Apple menu  > System Preferences, then click Software Update.

Or use this link to open the macOS Big Sur page on the App Store: Get macOS Big Sur. Then click the Get button or iCloud download icon.

Install macOS Big Sur

After downloading, the installer opens automatically. Click Continue and follow the onscreen instructions.

Please allow installation to complete without putting your Mac to sleep or closing its lid. During installation, it might restart and show a progress bar or blank screen several times. You might find it easiest to begin installation in the evening so that it can complete overnight, if needed.

Stay up to date

After installing macOS Big Sur, you will be notified when updates to macOS Big Sur are available. To check for updates, choose Apple menu  > System Preferences, then click Software Update.

Apple updates its macOS (previously Mac OS X) desktop and laptop operating system once a year, like clockwork, bringing new features and improvements. That’s all very well, but Apple’s most recent version of macOS – Big Sur – won’t run on any Mac older than 2013, and in some cases 2014. Which may well mean that your Mac can’t officially be updated – unless you follow this tutorial.

Before you go ahead and follow the advice below a word of warning: there is a reason why Apple chooses not to support the new Mac operating system on older Macs. Older Macs just don’t have the necessary components or power required to cope with the demands of the more modern systems. So if you do install Big Sur, Catalina, or any recent version of macOS on an unsupported Mac don’t expect it to run smoothly.

Is my Mac too old to update?

We have a macOS compatibility checker here, so you can see which versions of macOS your Mac should be able to run.

Here’s an overview of the Macs that will run Big Sur, according to Apple:

MacBook models from early 2015 or later
MacBook Air models from 2013 or later
MacBook Pro models from 2013 or later
Mac mini models from 2014 or later
iMac models from 2014 or later
iMac Pro (all models)
Mac Pro models from 2013 or later

Apple advises that macOS Catalina will run on the following Macs:

MacBook models from early 2015 or later
MacBook Air models from mid-2012 or later
MacBook Pro models from mid-2012 or later
Mac mini models from late 2012 or later
iMac models from late 2012 or later
iMac Pro (all models)
Mac Pro models from late 2013

Apple advises that macOS Mojave will run on the following Macs:

Mac models from 2012 or later
iMac Pro (from 2017)
MacBook models from 2015 or later
MacBook Pro models from 2012 or later
MacBook Air models from 2012 or later
Mac mini models from 2012 or later
Mac Pro models from late 2013 (plus mid-2010 and mid-2012 models with recommended Metal-capable GPU)

The older macOS High Sierra had a little more scope. Apple said that would run happily on a late 2009 or later MacBook or iMac, or a 2010 or later MacBook Air, MacBook Pro, Mac mini or Mac Pro.

If you Mac is supported read: How to update to Big Sur.

This means that if your Mac is older than 2012 it won’t officially be able to run Catalina or Mojave. In the case of Catalina that includes all the old-style Mac Pro models, pre-‘trash can’. If you want to run , but your Mac is older than 2013/2014, the new macOS just isn’t for you, as far as Apple is concerned anyway.

However, despite this it is possible to run newer macOS versions on older Macs thanks to a patcher.

Don’t expect things to be plain sailing though – in fact you should expect to encounter problems. Be prepared for the fact that your Mac will not function optimally and you could lose data. (For that reason we recommend doing a full backup of your Mac first).

For example, many older Macs have problems with the Wi-Fi connection after installing macOS Big Sur. If you need Wi-Fi, installing the preview version is not advisable.

Running Big Sur on another macOS on an unsupported Mac may also be considered against Apple’s terms and conditions. For information about Apple’s terms and conditions read: Should you agree to Apple’s terms and conditions.

How to install Big Sur on an unsupported Mac

If your Mac is more than a few years old and you try to install Big Sur on it you will hit a few hurdles – the first being the fact that Software Update simply won’t let you install the new version of macOS.

However, this doesn’t mean that installing Big Sur on an older Mac isn’t possible. It is – you just need a patch. Luckily there’s a patcher for installing macOS Big Sur on older Macs available – the big-sur-micropatcher can be downloaded from GitHub.

Note that macOS patchers cannot perform magic and not all Macs will be compatible. Before installing Big Sur on an older Mac, make sure that your Mac is compatible with the patcher. On the patch page (linked above) you will find some notes indicating the various years of manufacture. Before you upgrade to macOS Big Sur review the compatibility notes.

The procedure for updating to a new version of macOS on incompatible Macs is as follows:

First you will need to obtain the installation files for the operating system. You’ll have to obtain these using a compatible Mac. If they don’t show up in Software Update you can get the installation files from the Mac App Store.
Now you need to load these installation files onto a USB stick and prepare the USB stick for installing macOS Big Sur. We explain how to create a bootable installer of macOS in a separate article.
Next you need to obtain software that is able to trick the installation files of the version of macOS you want to install into believing that the Mac is compatible. You can download that patcher we mentioned above from GitHub. Click on the Code and Download Zip buttons.
After extracting the archive from your download you will find the file “micropatcher.sh”.
Open a terminal window and drag and drop the file into the terminal. Then run the command.
Now install macOS from your bootable installer.
In some cases, there are still tasks to be performed after the installation. These can be found in the instructions for big-sur-micropatcher. After preparing the Mac with the USB stick, start a terminal and enter “/ Volumes / Image Volume / set-vars.sh”. The script is pa
