Will the base model from 2015 be able to stream 4k videos on youtube without lag? I wanna buy the macbook because it's design. All i use the computer for is to surf the web and watch movies. nothing more.
Absolutely. I just tested on mine. Works perfectly fine (that screen is sooo beautiful). Those who experience lag likely experience it for one of two reason. Rare case of having a faulty unit or most likely a slow internet connection.
