I have an older iMac with 16 GB of ram and I'm running High Sierra and Safari 12.1.2. Recently, when I'm running Safari, I get very sluggish performance. I get a spinning beachball which lasts for up to a minute and constant page reloads due to "a problem". This is most notable when I go to the ESPN website but happens on other websites too. This doesn't occur using Chrome.
I have tried:
Restarting my iMac
Clearing the Safari cache
Closing other open windows
Nothing worked for Safari
Does anyone know what could cause this?
There is a very similar question that has been asked but the method mentioned there doesn't work for me.
