Step 3: open the macos big sur patcher file. Step 4: insert usb drive. Step 5: install macos bir sur on unsupported mac. Install macos big sur on unsupported mac. As new major versions of macOS are released and older versions become unsupported, we highly recommend you continue to update your macOS to a supported version in order to receive mainstream support such as security updates as well as new features (if you’re an Microsoft 365 for Mac subscriber). This applies for both Microsoft 365 for Mac. Patched Sur is a UI patcher for macOS Big Sur, designed to make it easy to run macOS 11 on unsupported Macs. This patcher hopes to allow any user of any knowledge to patch their Mac, while still giving you freedom on how you want to use your Mac. Aug 25, 2021 The macOS 11, which goes by the name Big Sur, comes with a newer user interface and menu bars, redesigning icons and other features. It is better than macOS 10.15, Catalina, due to its powerful improvement and new features. However, Apple dropped various Mac versions, making installation of macOS 11 on unsupported Macs almost impossible.
For Mac users, the release of the newest macOS update is always a big day. What will the new interface look like? What new features are there? And, importantly, will it be compatible with my Mac? Big Sur is a significant update that is supposed to bring macOS more in-line with iOS. However, with every new update older Macs get left behind even though some devices can last for several years. If your old Mac is optimized and you’ve taken good care of it then it’s probably still running great. Although older computers may not officially support Big Sur, it doesn’t mean that it’s impossible to install.
Which Macs Don’t Support Big Sur?
Whether or not your Mac officially supports Big Sur depends on the model as there is no set cut-off point. If you have any of the devices below then you’re going to have to install Big Sur the hard way:
- MacBook – mid 2010 and earlier
- MacBook Air – mid 2012 and earlier
- MacBook Pro – early 2013 and earlier
- iMac – late 2013 and earlier
- Mac Mini – late 2012 and earlier
- Mac Pro – mid 2012 and earlier
All of the devices mentioned above are now seen by Apple as obsolete products, meaning they’re no longer supported technically either by replacement hardware or through OS updates.

MacBook Pro Issues
Some MacBook Pro users are having difficulty with Big Sur even though their device is technically compatible. Anyone with a late 2013 or mid 2014 model MacBook Pro is able to upgrade their system but may end up facing a permanent black screen. Thankfully, Apple has offered a workaround for users experiencing these kinds of issues. In spite of this, some people are still having problems and in that case the only solution is to contact Apple Support directly for help.
How To Upgrade an Older Mac To macOS Big Sur
Anyone with an incompatible Mac will have noticed that Software Update doesn’t give you the option to install Big Sur. To upgrade you’ll need a patcher to trick Software Update into thinking your computer is compatible. But before you get started, there are a few things you need to do.
First, you need to make sure you’re starting the process with your Mac running Catalina. You’ll also need a couple of USB flash drives with at least 16GB storage. These drives must be modified in Disk Utility to work as your bootable OS installer. The first flash drive is for Big Sur and the second is to be used as a backup installer for Catalina in case anything goes wrong in the process. It’s also worth taking advantage of Time Machine for an extra safety net.

Of course, you’ll also need to obtain a copy of Big Sur since it won’t be available to download automatically. There are two ways to do this. First, you can register with the Apple Beta Software Program for free to download the beta. However, using a beta version can cause issues. Instead, it’s better to register with the Apple Developer program at $99 a year to download the finished article.
Next, you’ll need to find a patcher online that will be able to trick your system into installing Big Sur even if it’s incompatible. There are a few of these around and you’ll easily be able to find one on GitHub, like user barrykn’s micropatcher. But since each patcher works in slightly different ways, it’s important you follow every step of the process to the letter. You don’t want to end up with a broken Mac, after all.
When Not To Update an Unsupported Mac To Big Sur
Just because you can install Big Sur doesn’t necessarily mean that you should. First, it’s a very complicated process as the Big Sur update is one of the most significant in recent times, making it more difficult for patches to be created. In the past, like when upgrading older Macs to High Sierra, there were ready-made patches that made life easy. Anyone who isn’t a technical wizard may have issues with Big Sur if they don’t follow guides exactly. You also need to be sure that you’re confident using the Mac Terminal, as it’s an important part of the process.
Depending on what system you’re upgrading from, you may encounter issues that affect your Wi-Fi connection, graphics bugs that slow down your system, or frequent crashes. This is because Big Sur is relying on more recent hardware that simply doesn’t exist in older models. You’ll also find that new versions of the software you use daily are built with the assumption that you have Big Sur working without any issues. Meanwhile, much older systems will need significant upgrades to even have the capability of running Big Sur in the first place.

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.
Macos Big Sur For Unsupported Macs
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 part of the patch for macOS Big Sur and changes important settings for booting and system files.
The update can take several hours. In our case it sometimes looked like the installer had crashed during the update. In this case you should wait, as the installation is usually still in progress. Over time, better ways to update a machine may be found. Currently, the safest approach is to update using a bootable USB stick.
How to install Big Sur updates on an unsupported Mac
Once you have installed macOS Big Sur, updates will appear in Software Updates as soon as they are available. However, you should not install these, but ideally again create a USB stick with the current installation files and install the update in this way.
These steps were translated from an article by our colleagues at Macwelt.
How to run Catalina on an older Mac
You can download a macOS Catalina Patcher from a developer known as DOSDude1. The patch will enable you to install Catalina on an older Mac.
The Catalina hack doesn’t work with every Mac, but many are covered. You can see if your Mac is supported here.
DODDude1 offers a video tutorial on his website, here. We’ve simplified the steps below, but we recommend that you follow his tutorial.
- Download the latest version of the Catalina patch here. (You can make a donation).
- Open the Catalina Patcher app.
- Click Continue.
- Choose Download a Copy.
- The download (of Catalina) will start – since it’s almost 8GB it is likely to take a while.
- Plug in a flash drive.
- Choose ‘Create a bootable installer’ from the options.
- Plug the bootable installer into the Mac you wish to update.
- Restart the Mac while holding the Option/Alt key. This will cause the Mac open in Startup Manager.
- Choose the bootable installer drive and Enter.
- Now your Mac should open in Recovery.
- Choose Reinstall macOS and wait for the new version of macOS to install.
- After the installation has completed, you should restart the Mac in Recovery mode again, choosing the drive that contains the bootable installer.
- Now choose macOS Post Install and the required patches will be installed on your Mac so that Catalina can work.
- When the patches have been applied choose Force Cache Rebuild.
- Restart.
- When it reboots, your Mac should now boot into a fully working copy of macOS Catalina.
If you are running a version of macOS that predates High Sierra or Mojave, you will need to format your hard drive to APFS.
We have more advice about installing macOS via a Bootable Installer here.
How to run Mojave on an older Mac
As with Catalina, a patch tool was written DOSDude1 that enables you to install macOS Mojave on an older Mac.
You can download the Mojave Patch Tool here.
How to run High Sierra and older on an older Mac
DOSDude1 wrote a similar patch for High Sierra and prior to that Sierra. With the patch installed you can go back as far as early 2008 models. It’s unlikely to run like a dream, which is why Apple advises against this course of action. But you should be able to achieve tolerable performance.
Why you shouldn’t install new macOS on an old Mac
We’d advise tech beginners against attempting this workaround: it calls for a moderate degree of tech expertise.
Remember that we’re going against Apple’s official advice on this one, which means that if something goes wrong – and that’s always a possibility with an OS install, even if you’re using official software – your warranty is unlikely to save you. Of course, it’s unlikely that your 2008 Mac would be under any warranty so that may not worry you too much.
Back up your Mac before going any further. And bear in mind two more caveats.
At some point Apple may patch this hack and prevent it working in future. So if you’re keen, and happy that the risks and difficulties are worth it for you, then jump in while you still can.
