Sophos Mac Anti-Virus Kernel Extensions Created With Old SDKs

Marty_W

From a satisfied user!

In doing some post-Mavericks installation system clean up I discovered the following:

Amongst the Kernel Extensions loaded at boot:

com.sophos.nke.swi(9.0.53 - SDK 10.8)

com.sophos.kext.sav(9.0.53 - SDK 10.7)

My concern is that the software development kits 10.7 and 10.8 might be generating code that has been depreciated and that this might account for some users' issues.

Is there a  plan to update those kernal extension under SDK 10.9?

Thanks,

Marty

    Hi Marty,

    This is a fair question and thanks for asking. There are two concerns for us when Apple releases new platform SDKs: what functions we are using are deprecated? and what new functions are now available to us?

    Our extensions are not using any deprecated functions so there is no rush to update, at least not yet - lets see what happens after Mavericks. The additional concern we have is around backwards compatiblity. Unfortunately the latest SDKs and Xcode tools don't build extensions for Mac OS X 10.6 32-bit kernels. So moving forward means either cutting off support for a significant percentage of our user base (about a quarter million endpoints) - or forking the product into different versions. Neither is particularly attractive today.

    Hope that helps.
