[solved] UR44 unricognized on iMac Pro

[fredomusic]

I have a new iMac Pro (2017), this one turn on High Sierra 10.13.4 and and (old) iMac (Retina 5K, 27-inch Late 2014) and this one turn on High Sierra 10.13.4 too.
My UR44 works without perfectly on ma (old) iMac, but impossible to use it on my new iMac Pro. I have the Tools for UR44 installed (Yamaha Steinberg USB Driver V1.9.10) but the UR44 is not recognized by my iMac Pro.

Solution : The Yamaha Steinberg USB Driver V1.9.10 (in UR44-Tool pack is not the last version)...
