I use MIDI software for configuration and playing instruments and Its a best software than other which is available online but MIDI software is easy to use, and basic user interface, but I am trying to install my old MacBook 2013 model but the installation failed, I am trying to install other musical software but the same issue it might be an Operating System issue or software issue, as of now I want to check my laptop with someone MacBook technician and trying to find macbook repair downtown, I already got a solution in online I I tryed to do same setting but nothing change,
