UR22 compatibility with Macbook

I’ve tried to connect the UR 22 to my Macbook, but it won’t recognize the device. I connected my UR 44 that I typically use with my ipad to the Mac and it recognized the device and setup with no problems. Does anyone know if there’s a compatibility issue with the UR 22 and the Mac?
Thanks

A UR22 should be fine with a Macbook (that’s how I use mine). What OS are you on? Reinstall the latest Tools from http://www.steinberg.net/index.php?id=downloads_ur22&L=1

Do you still have the problem after a restart? If so, what do you see currently in your Audio MIDI Setup?

I use the UR22 with my 15" Retina MacBook Pro, has always worked great.
