Endpoint Protection

Upgraded a few Macs to Sierra today.  No issues with the upgrade itself that I noticed.  It looked smooth enough.

After logging in on a domain account and going through Apple's security prompts at the beginning, there's an extra message on a few machines....

"The system extension 'SymInternetSecurity.kext' is not compatible with this version of OS X and can't be used.

Please contact the developer for updated software."

I can get live updates fine still.

SEP version on that mac is...

12.1.6867.6400

Is that error message a security concern at all? 

Dang.  Yep.... From the Symantec Solutions folder in Applications, I can run Liveupdate fine.  SmallScanner (not sure what that is) will start/appears in the dock but doesn't do anything.  Symantec Endpoint Protection just hops a few times in the dock but doesn't actually come up.

Is this fixable?    We need a fix for Anniversary Edition on Win10 and then Sierra.....

The first version to support Sierra is 12.1.6 MP6, which was just released a few days ago. You need to use MP6.
