Hey guys, I've been using imacs since 2010 and have always been happy and I already have one imac late 2015 fully maxed out 5k. It gets hot and fans kick in when i watch or edit any 4k videos. But the screen kind of makes up for its short comings. I just bought like new macbook pro 2015 15" base model with i7 and iris graphics...but I am seriously not happy. The screen looks pale as compared to my surface pro 4 and the iPad Pro 12.9 they all have similar kind of ppi ... first the screen is pale, the sound is just ok and it feels slow and fans start going with full noise as soon as I start to play a 4k video. I highly doubt this will be good for any kind of 4k editing. Any idea how to make this fan noise go down? This is rubbish really, its a £1899 machine Apple?? seriously? I really like Surface products now, they look good and dont have any crapware so they run fast.
