Hello, I have a iMac (Retina 5K, 27-inch, Late 2014) lately I've been having some performance issues with apps like After Effect CC and Unity 5. The apps have been freezing on me a lot now (used to not) and was wondering if there was away to find out how reason why and how to fix it? I did tho find a app on my mac called "macbooster mini" tho I don't remember ever installing it but some people say they got it from VLC. I was wondering if something like this could be the reason to why something like this would happen. If it is / if not is there away to find out whats wrong and how to fix it or would maybe a full clean re-install of the OS fix the issue to? Thank you for your time and I hope you have a great day.
