What MacBook do I need? Currently I own a mid 2011 MacBook air, 4gb of ram and a 1,7 intel core processor. It stutters and lags when I try to watch youtube in 1080p 60fps. I´m waiting for Apple to release the updated MacBook pros, hopefully an option without the touch-bar. I don´t know much about hardware, but I can tell you what I want my new laptop to do: - run youtube videos smoothly; 4k/1080p 60fps; no stutter, lag, cooling fan spinning on max. - run any browser with multiple tabs smoothly. - light editing of video or pictures, using Apple software. Do I need a maxed quad-core cpu and a lot of ram? Or are there cheaper options for my use?
