Installing Mac OS Big Sur on unsupported MAC
I currently have Mac Book Air Mid 2012 laptop and want to upgrade the current OS version to OS Big Sur. This version of laptop is not supported by this newer OS. I am not going to spend thousands of dollars to get a new laptop or the one that is compatiable with Big Sur. I came across with Patched Sur and see how it will work for me.
You need to make sure that your Laptop will work fine after installing Mac OS Big Sur as there are some issues if you are installing this on Macs older then 2012/2013. You can read full description here.
