Works for Mac

I have a MacBook Pro and wanted a number pad for a few music applications where important functions are located on the numeric keypad. My first attempt was a different model and worked satisfactorily. This works here and is kept reasonably close to the design of Apple keyboards.
It makes a somewhat cheap impression, but except in the reception area from the Apple campus in Cupertino should not be a problem.
Attention Sibelius users:
The top row (= / * del) is arranged differently on the Nummernpads the big Apple keyboards (clear = / *). However, the occupancy at Sibelius remains as indicated on the virtual window viewing keypad; only the Delete button overrides the intended function of Sibelius. It lacks a function to get a jump back to the first assignment (Note Become). You have to repeatedly press the minus button to come back again.
