-My files are officially deprecated and are superseded by the tutorial of KNNSpeed. You can read his tutorial on [InsanelyMac](http://www.insanelymac.com/forum/topic/324366-dell-xps-15-9560-4k-touch-1tb-ssd-32gb-ram-100-adobergb%E2%80%8B/) or as PDF version attached [here](KNNSpeed/Dell XPS 15 9560 Guide.pdf). I also attached his files to this repository as a mirror but i really suggest using the newest versions from his thread. You may still need some of the original files in case KNNSpeeds tutorial is not working for you (for example when your drive is not 4Kn compatible).

 The original tutorial is still available in the [readme_old.me](README_OLD.md) and requires the files from the [Dell 9550 Sierra Installation Guide][1].
