You can follow the tutorial, of course. The OP has not been around since March so you'll have to follow-up on anything not working and we'll try and help you.

@Pippo BalestrieriThis thread has long been dead; it's been 5 years since the OP wrote his single post and visited the forum. Do not expect a response. For what it's worth, back then, ML would have most likely been installed with the myHack tool that we advocated and supported at the time. There are several models and generations of a ThinkPad Helix. OP's model was clearly an Ivy Bridge/HD 4000 one. Open up a new thread with your own model's specifications and we'll see what we can do, preferably with current macOS High Sierra (really no point considering obsolete ML in 2018). This old and dead thread will now be closed and archived.
