Applies to: Sophos Home for MacOS 10.15.4+

What’s happening: 

MacOS customers running Catalina MacOS 10.15.4+ will receive the following message:
Legacy System Extension
Existing software on your system loaded a system extension signed by “Sophos”, which will be incompatible with a future version of macOS. 


This is related to changes that took place in macOS 11 (Big Sur), in which kernel extensions are longer used. More information hereAbout legacy system extensions.

NOTE: Sophos Home 10.0.1 which supports macOS 11 is now available: See: Support for macOS 11- Big Sur which uses the supported System Extensions.

What to do:

No action required other than clicking OK –  Current protection is not impacted in any way, and this notification from Apple is just informational.
