This is a bit long winded so I'm sorry but have to explain as I am simply looking for advice from someone who might use photo-editing software. I picked up a mid 2012 I mac without an operating system and upgraded it to Sierra. Now here is where the issue starts. I currently use Adobe CS 4 (Photoshop and in-design on my windows based PC). Should I install boot camp and then install windows 7 and then reinstall CS 4 or keep it Mac only. I hear there is a program from Affinity photo which is reasonably close to mac. My big problem though is there is no real comparison to in-design. On the flip side though i heard windows on the mac even though it runs it runs extremely slow. (my machine has 2.5 GHz processor and 20 megs of ram). I bought this because i heard mac's are much better at doing design work.
