How much ram does 500 Safari tabs take up on an iMac 5K 27-inch? I‘m a tabby person which means I like to have lots of tabs open, It’s a nightmare for me to have that many tabs open all the time on my 2019 iPad with 3GB of memory. I was thinking of getting 32GB of memory from Amazon when I buy a iMac later, but now I’m thinking of 64GB or 128GB of memory from Amazon.
