downgrading safari will not fix the issue guys, you need to downgrade your whole OS
essentially find the previous build of the OS (in my case 11.7.2) on the internet & make a bootable USB install & downgrade from there...
when you think about it, this by design apple purposely slows down older machines & phase out features eventually releasing buggy software all to frustrate everyone & their responses to all support queries is: "we no longer support legacy systems"
all to push everyone into buying new hardware..
well APPLE not all of us have $$$ to do so, some of us are lucky to even own a Mac even if its 2nd hand.
& in this changing economy with inflation on the rise more & more people are getting poorer by the day..
I wonder what the next update will include which part of the system they will break next..
