You’re going to need a slightly more modern Mac to install the MPC 2.x software on. Your Mac is 13 years old and probably stuck on OS X 10.9 or similar. Looks like you can install up to OS X El Capitan (10.11.6) on your 2009 MacBook Pro. (https://www.macworld.co.uk/feature/what ... e-3776008/
). My late 2012 Mac Mini running Catalina 10.15.7 is able to install/run the MPC software.
According to the FAQ (https://inmusicbrands.force.com/maudio/ ... ns#Support
), it should run on El Capitan (assuming you have a 64 bit Mac). Maybe not the latest and greatest 2.10.1 version of the MPC 2 software, but maybe an older version?
