I have a mid 2012 MBP and it is has been running very slow lately. The only demanding applications that I run in my opinopn are Adobe Photoshop Lightroom and my large iTunes library, that's about it. But I can be running Safari with iTunes in the background and it will freeze and I will get the rainbow wheel. I have run virus scans and nothing has popped up. I replaced the RAM last year because one burnt out. Is it time to just get a new laptop and trade this one in? I have attached my specs also. Thank You in advance!
