Old subject I know. I have tried various suggestions made on this site to speed up my late 2012 Mac mini purchased in April 2014 as a basic unit with no upgrades as I basically just use it for email, internet sports and news sites and some basic photo editing in iPhoto. I was disappointed from initial date of purchase, took unit to Apple Store where they ran diagnostics on it but found nothing. Still have about 8 months warranty left as I bought 2 year warranty. Since I don't run hardly any apps, have added only 2-3 don't thing increasing RAM or changing to SSD is going to help. Installed Onyx and it did not find anything significant. Subscribe to TWC that claims to deliver internet speeds up to 100 Mbps, I normally get anywhere from 10-30 when I run speed tests but still unit should be a lot faster. Get a lot of beachballs, new pages normally take 10- 45 seconds to load and often completely freeze. I'm 74 yrs old and consider myself at best an intermediate level home computer user. Any suggestions with some detailed instructions would be greatly appreciated. Not sure if this should be posted under OS X or Apple Desktop category.
