Latest OS X update has affected Safari/AppleTV performance. How to I revert to the previous patch?

Hi,

I have an old(er) iMac (purchased 2012 - last one to have a disc drive). I just updated to the latest OSX patch and it has caused Safari to slow way down (rainbow daisy-wheel keeps spinning) and streaming to my AppleTV is sporadic and drops as soon as the iMac goes to sleep.

Will there be a new OS X patch or should I revert to the earlier patch. If the latter, please provide instructions on how to do so.

Thanks a lot!

iMac (27-inch Mid 2011), OS X El Capitan (10.11.6)
