[maxmsp] aka.serviceusb object - intel macs

the aka.serviceusb object runs the service usb interface from max. now i hear some people have problems to use the object on intel macs. 
is there a incompatibility known with the intelmacs? or does the object also work with intel - macs?
thanx for hints

kind regards 
ath
or? when updating from max 4.5 to 4.6 there was a message that some externals had to be transformed. ist there a transformation that has to be done?
