Issues upgrading firmware on iConnectMIDI2+ on Mac and device is stuck in boot loader mode.
iConnectMIDI2+ firmware upgrade can only be done when the computer is connected to the USB 2 Device Jack on iConnectMIDI2+.
- Disconnect any devices on the iConnectMIDI2+ and disconnect the iConnectMIDI2+ from your computer.
- Open your Mac’s Audio MIDI Setup and remove any iConnectMIDI2+ you may find in the MIDI Studio Window.
- Re-connect the computer to iConnectMIDI2+ USB 2 Device Jack and open iConfig.
- iConfig should recognize the iConnectMIDI2+ in boot loader mode and when selected from the 'Device selection' screen, it should prompt for firmware upgrade again.
Accept to upgrade and iConfig should properly upgrade the device.
