This tutorial should work with most 4K monitors and traditional DisplayPort connectivity as well, the USB-C cable used in my example is carrying DisplayPort 1.2 across its lanes. In other words, if you decide to apply this patch, know that you are doing so “at your own risk”. Perhaps it plans to release a future OS X upgrade with 60 Hz support in tow. Maybe Apple wants to sell more MacBook Pros. Perhaps it has to do with heat or some other vital system aspect. The Intel Core M chip, along with the Intel HD Graphics 515 integrated graphics, support 4K resolution at 60 Hz.Īpple may have a valid reason for holding back 4K 60 Hz. DisclaimerĪs to why Apple did not enable 60 Hz resolution out of the box on the 2016 MacBook, I’m still not sure. Watch the step-by-step process in our video tutorial for the details. In fact, I just did so on the LG 27UD88 4K USB-C monitor that I recently reviewed. The good news is that it is possible to enable 60 Hz at native 4K resolution and 1080p (HiDPI/Retina) resolution on a 2016 MacBook.

It’s not immediately clear as to why this is, but on its support page, Apple makes it known that 4K resolution is limited to 30 Hz. Sadly, the MacBook only supports 30 Hz out of the box for 4K resolution. Operating at 30 Hz results in jerky and choppy cursor movement, and in some cases can induce headaches after prolonged use. The jump in refresh is a big deal, as anyone who’s tried to put up with running a 30 Hz refresh rate can attest to. One of the great things about the new Intel hardware inside of the 2016 MacBook is that it’s capable of supporting 4K resolution at 60 Hz. Such a feat is achievable via an easy-to-apply IOKit patch. The 2016 MacBook is capable of driving a 4K display at 60 Hz via a single USB-C cable.
