Hi, I'm looking at getting this mac here: Refurbished 21.5-inch iMac 2.8GHz Quad-core Intel Core i5 16GB memory 1TB Fusion Drive Intel Iris Pro Graphics 6200 I use photoshop heavily, for art mostly, drawing, painting. It's my proffesion so I need something that will work and work fast with no hiccups. I've found many threads saying that people have a lot of trouble getting PS working on their macs with these similar configs, but they are all old posts, pre 2014. That said it's hard to find any recent dealings with these matters and maybe because there just aren't any but if someone could weigh in for me here, I'd be very grateful. I tried talking to apple today and they were no help at all.
