Great mouse+keyboard for MacArvosana 4/5
I bought this mouse and keyboard for a macbook pro and it worked very well. You only need to adjust a couple of keys to simulate the mac's key order for example keys ctrl, alt, cmd. With the windows keyboard they are ctrl, cmd, alt, so you need to switch in keyboard settings.
Also as an alternative I went to keyboard settings and made buttons F1-F10 to have the same functions as Mac keyboard, for example swapping desktop views left to right is F4-F5 and showing the launchpad is F6.
