I buy this keyboard to be use with the Logitech Marathon m705 mouse , use its unifying usb transceiver . the problem I have be that it do not come with a software for set up the keyboard , like the one that be available for the mouse . from Logitech , I could download the control center that be suppose to work with the mouse m705 and `` any '' other device unifying compatible . I be able to configure the mouse , but the keyboard be just not there . it be certainly recognize as a keyboard , and I be able to use it , but the software do not recognize it as the Logitech k350 . the keyboard come with a cd that have the software , but be only available for Windows xp , Vista , and 7 . I expect a Mac version , since the review table list on this item 's page show Mac compatible ! I expect at least that Logitech make available the proper software to be download from they web site .
