macOS Big Sur 11.4 Compatibility Issue with Sophos Endpoint Installer

Question

Is the current Sophos Installer for mac OS on the Sophos Central backward compatible with macOS Big Sur 11.4? Our devices with macOS Monterey were installed without issues but when we tried using the same installer to our Macbook that's running on macOS Big Sur 11.4, it is saying "You can't open the application "Sophos Installer" because this application is not supported on this Mac.". 
 We are also not considering to upgrade the OS of this specific Mac because we need this specific OS for our testing purposes at work.

Hi Jaason, 
 Thanks for reaching out to the Sophos Community Forum. 
 At this time macOS 11.4 is no longer supported. You can see the system requirements for installation in the following article. - Sophos Central for Mac System Requirements 
 I am not aware of a workaround that would get the installer to recognize the OS version differently which may allow you to install, though, the system would still be unsupported.
