Will Apogee USB interfaces work with USB 3.0 ports on my Mac?

Yes, Apogee interfaces including JAM, JAM 96k, MiC, MiC 96k, GiO, Groove, Duet 2, Duet for iPad & Mac, ONE, ONE for iPad & Mac, Quartet, and Symphony I/O have been tested and work well with USB 3.0 ports.


Although Symphony I/O works as an audio interface with USB 3.0 ports, you will need to use a USB 2.0 port or a USB hub to run the Symphony I/O firmware updater.
