Trying to connect a 2007 Yamaha

Hi,

I am using Sibelius Ultimate 2020.3 on an iMac.

I am trying to connect my Yamaha PSR-E313 YPT-310 (2007).

I have a Roland UM-ONE MK2 USB MIDI Interface and it works beautifully on my PC running Ubuntu Studio. I have been using it in conjunction with Rosegarden to record and play MIDI files. I transfer files to and fro my iMac using Dropbox.

I installed the Yamaha driver (https://ca.yamaha.com/en/support/updates/usb_midi_driver_for_mac.html) but it did not work. The keyboard was still not recognized.

Any advice on what driver I should install?

It works perfectly on Ubuntu Studio, so all I need on my iMac is the right driver.

Any help would be appreciated. Thanks in advance!
