Young Guru has shared an Instagram post hinting at his acquisition of an Apple Mac Mini, suggesting he's gearing up for some serious production work.

I do all my main composition, recording, and mixing inside Logic X on a Mac Pro cylinder, and output the results to as many as eight 5.1 stems which are routed via MADI over to a second Mac Pro running Pro Tools HD-Native, which is acting as a basic layback recorder. A third computer, a Mac Mini, is slaved to Logic via MTC and is running Video Slave software that I helped to develop. This takes the video playback load off of the main Logic machine and simplifies things a bit. I use MOTU 112d and 1248 AVB interfaces, along with a UAD Octo, on the Logic machine, and Avid MADI and SyncHD interfaces on the Pro Tools stem recorder. I repurposed a couple of older Mac Pro towers as orchestral slaves running Vienna Ensemble Pro, although I use these pretty rarely, and I do a fair bit of sound design and rhythm programming in Ableton Live and Reason which run as ReWire slaves behind Logic. Tons of plugins, as you'd expect, ranging from the amazing UAD stuff to more out-there stuff like Sinevibes and Audio Damage.

In this facebook post Mitis explains that he uses a Mac Mini.
