Limited website access on my 2011 MacBook Pro
I own a 'vintage' 2011 model MacBook Pro 13" laptop. Recently I've noticed a more frequent inability to fully access websites I've visited for years. Instead, I get a website 'diagram' listing an 'index' of the website's contents. I don't understand why this is happening. I suspected that perhaps my 'vintage mac' is not equipped with the more advanced and newly upgrades of today's 2023 tech. My mac runs on a 2.5 Intel Core i5 OS processor and may not have today's "stuff" to process today's tech properly. I'd certainly appreciate it I could get relative support and/or assistance regarding this situation please.
Thank you
