Had basic function problems with both Targus and SATECHI remotes. Now looking into Kensington and Logitech 400. Logitech states no support for Macs with this product, but several people on Logitech forum report out-of-the-box compatibility for advancing PPT slides and other functions working well w/ Apple laptops running OS X, e.g., on MacBookPro. Any comments or suggestions would be appreciated.
