Websites reload and won't open
I have a 2012 MacBook Pro, after an update, certain websites try to open, reload and after 2 attempts a message, 'a problem repeatedly occurred,' appears. I read the forums tried all the suggestions, nothing. I disabled javascript and the website will remain open but won't do anything else. I am running a currently updated version of Catalina, the newest OS Apple says my computer will run. I figured 10 year old computer update, so I ordered a new 2021 13" MacBook Pro M1 processor 16g ram everything upgraded. The same problem occurred on the new MacBook Pro. I returned it.
The problem ISN'T because my MacBook is 10 years old, it has to be a software issue and Mac support was totally useless when I talked to them. Can anyone give or lead me to a solution? I have NEVER had any issue in the past. None, but I will not stay with Apple products if this issue persists. Help me........
