Hello... I don't know if anyone here is up for this, but I'm at the end of my rope. I have a Mid 2012 Mac Book Pro that has stopped updating past Catalina and it's unable to run Chrome. I one use this for the internet and websites are hit and miss - some will load, some won't.

I don't want to get rid of this computer! I love it! I don't want a new one and it annoys me that I would have to buy a new laptop just for the internet. That's silly. It runs perfectly well otherwise.

Can some nice person please direct me to the basics of updating this to a newer iOS? I tried digging through the sub, but y'all are light years ahead of me in terms of computer know-how and I couldn't find a post about how to start the process. I'm not super computer savvy, BUT I am spiteful enough that I will give it my best shot.

Any advice would be greatly appreciated. Thank you!
