LN uses two, parallel MCAO systems, each of which corrects turbulence at two atmospheric layers, to deliver near diffraction-limited imagery over a two-arcminute field of view. We summarize LN's approach to MCAO and give an update on commissioning, including the achievement of First Light in April 2018. This is followed by a discussion of challenges that arise from our particular type of MCAO and the solutions implemented. We conclude with a brief look forward to the remainder of commissioning and future upgrades.ELETTRONICOenConference paper10.1117/12.23134212-s2.0-85053552934000452819300009https://www.spiedigitallibrary.org/conference-proceedings-of-spie/10703/2313421/Commissioning-multi-conjugate-adaptive-optics-with-LINC-NIRVANA-on-LBT/10.1117/12.2313421.full2018SPIE10703E..0BHFIS/05 - ASTRONOMIA E ASTROFISICA
