No but I do have a few kexts like CPUSensors.kext that I believe was installed by HWMonitor (will double check) and Soundflower.kext.   Next time I start testing I will definitely keep the kexts to the bare minimum and then start reinstalling or replacing into the Extensions folder (either inside Clover or Library/Extensions one boot at a time.   I don't have anything installed into /System/Library/Extensions only the default kexts.   I had removed that kext when I had upgraded from EL Capitan to Sierra back in the fall.  Thanks for the input though.

Ok that was pretty quick.  Ran the downloaded update .dmg instead of the App store version and up and running.  Wow definitely notice an improvement, not that things were slow before.  Things feel a bit zippier now.  

 

 

Did a bit more testing and all is well.  Downloading the update directly does the trick.  I think you guys can mark this one as solved :)

 

Thanks again for all the suggestions.
