Problem finding Safari update
I am running MacOS 11.5.2 on a MacBook Pro with Safari 14.1.2 and I want to upgrade Safari to keep up with security patches without upgrading the OS because it is an older Mac (circa 2015) and I am concerned it doesn't have the horsepower to deliver good performance running the newer OS.
Based on various various support posts I read, I tried looking for a Safari update in the App Store and also in System Preference / Software update and I do not see it.
System Preference / Software update lists an OS update to Monterey but nothing else.
Does anyone have any suggestions how I can find a stand-alone Safari update?
Thanks much for any advice anyone may have!
