Sadly, these Macs are way too old to even boot Big Sur, so they do not support this patcher. Note: 2008 Mac Pros do work with Big Sur, but not with this patcher. I recommend checking out StarPlayrX's BigMac Patcher for those. To install macOS Big Sur on an unsupported Mac we must do it on a disk partition and from macOS Catalina. This way if something goes wrong, we can always continue using our Mac as if nothing else. To make a partition follow these steps: Click on the magnifying glass and look for the app Disk utility. Up click on Create partition. 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. A look at the current state of ASIX-based Ethernet adapters and their behavior in macOS Big Sur with a focus on Plugable products like the USB2-E100, USB2-E1000, USB3-E1000, and USBC-E1000.

macOS Big Sur 11 release date: 2020.11.12 - Unsupported models and problems
According to the summary of macrumors, unsupported Macs can be divided into several situations:
Mac models that officially support macOS Catalina but are not supported by macOS Big Sur:
– These Macs can run Big Sur normally, but Wi-Fi cannot work normally. (This type of model is the easiest to run Big Sur perfectly through the patch, currently it is only a Wi-Fi problem.)
You can follow the steps below, this article is mainly for this type of model.
2012 and Early 2013 MacBook Pro
Not officially supported in macOS Catalina, but are fully capable of running both Catalina and large Sur with a Metal-compatible GPU and upgraded Wifi/BT card. Mac can be patched to run macOS Catalina normally, and it may be patched to run macOS Big Sur: – These Macs can currently launch Big Sur, but there is currently no Wifi or graphics acceleration support. This type of model requires additional steps to solve installation problems. Early-2008 or newer Mac Pro, iMac, or MacBook Pro: MacPro3,1
Macmini5,x (systems with AMD Radeon HD 6xxx series GPUs were almost unusable when running Catalina and will be under Big Sur as well.)
MacBook5,2
Xserve3,1*
*Not officially supported in macOS Catalina, but are fully capable of running both Catalina and large Sur with a Metal-compatible GPU and upgraded Wifi/BT card.
Completely unsupported Mac:
This type of model does not need to consider installing Big Sur.
Macmini2,1
— The 2007 iMac 7,1 is compatible with Catalina and potentially Big Sur if the CPU is upgraded to a Penryn-based Core 2 Duo, like a T9300.
2006-2008 MacBooks:
MacBook4,1 (as with Mojave and Catalina, we’ll get on our own here, but Big Sur are going to be running on this machine!)
2008 MacBook Air (MacBookAir 1,1)

(0) Prerequisites
Make sure the Mac is currently running on macOS Catalina.
(1) Boot to recovery mode (recovery mode)
When booting or restarting, press and hold Command + R until the splash screen (Apple logo) appears.
If there is no recovery partition, you need to press Command + Option + R to start Internet Recovery.
(2) Disable sip (System Integrity Protection)
Utilities -> Terminal Enter the command csrutil disable and press enter.
(3) Disable compatibility check
Continue to execute commands in the terminal:
1
nvram boot-args=”-no_compat_check”
(4) Restart, start macOS Catalina normally
(5) Disable libraries validation
Open the terminal and execute the command:
1
sudo defaults write /Library/Preferences/com.apple.security.libraryvalidation.plist DisableLibraryValidation -bool true
(6) Insert library
Put the downloaded Hax.dylib file in the home directory, namely /Users// directory, and execute the command in the terminal:
1
launchctl setenv DYLD_INSERT_LIBRARIES $PWD/Hax.dylib
(7) Start to install macOS Big Sur
Clean install
Before starting the installation, we open the “Disk Utility” to create a new APFS volume, and then double-click Install macOS Big Sur in the application to start the installation. Select the newly created volume as the target disk. After the installation is complete, it will automatically boot to the new system.
After installation, you can delete the APFS volume where the original system is located, leaving only the Big Sur system.
Upgrade installation
Double-click Install macOS Big Sur in the application to start the normal installation. The installation target partition selects the partition where the current system is located, that is, the upgrade installation is performed automatically.
By default, the factory setting has only one partition named: Macintosh HD
(8) Solve the problem of network card driver
In some models, the wireless network card is already working (Late 2013 iMac, or your 2012/2013 model uses an 802.11ac network card instead of an 802.11n network card).
If the wireless network card cannot work, you need to deal with it as follows:
You need to use the method in item 7 below to create a bootable U disk. Restart the system, hold down the Option key until the boot partition selection screen appears, boot to “Install macOS Big Sur”, after booting, select “Utilities -> Terminal” and execute the following commands (three formats) Both can be supported, choose one of them, “Macintosh HD” is your default system installation partition name, replace it according to the actual name):
1
2
3
/Volumes/Image Volume/patch-kexts.sh /Volumes/Macintosh HD
‘/Volumes/Image Volume/patch-kexts.sh”/Volumes/Macintosh HD’
“/Volumes/Image Volume/patch-kexts.sh” “/Volumes/Macintosh HD”
Then restart to macOS Big Sur, at this time Wi-Fi is already normal. - Installation method: fresh installation using removable media
Tip: U disk can also be replaced by mobile hard disk, especially SSD mobile hard disk, which is faster.
7.1, create boot media
(1) Create a bootable U disk
Prepare a 16G or above U disk, open “Utilities> Disk Utility”, select the U disk, click “Erase”, the format is as follows:
Mac OS X extension (Journaled);
GUID partition map;
Partition name: MyVolume (The default is Untitled, which can be customized. Note that MyVolume in the terminal command below should also be changed to the same name you customized)
Open the terminal and execute the following command:
1
sudo /Appli
