Hi all, I just upgraded my 4GB of memory in my late 2012 mini. It was getting slow especially with each new OS and Sierra really caused memory usage to go up to the point that on a cold boot and at the Desktop I was already running compressed memory and was utilizing the swap file. So I purchased on Amazon 8GB of Crucial memory 2x4GB and was surprised how fast opening Safari has become. It opened almost instantaneously with no spinning beach ball. The beach ball was common with 4GB of ram. My questions are: 1) Was 8GB enough or should I have gone with 16GB? Please note, I'm a lite user, (web, email, etc) keep one or two programs open max, and no more than 2 tabs of Safari open at any time. 2) Should I clear PRAM? 3) Should I reinstall macOS Sierra with the new memory? So far things appear stable, no issues but I'll leave it up to the experts. So far just increasing the memory has made my 2012 mini much, much quicker. I've read that usually replacing the HDD with an SSD increases the system speed but so far I'm quite pleased. Lastly, it's nice to have a system where you can still interchange parts to increase it's longevity.
