Because they ' re PS 3 games . PS 4 is not backwards compatible . They ' d have to be rebuilt for PS 4 . <| sep |> And no amount of information is actually going to change their minds because and facts that go against their worldview are discounted . sigh these are cheery thoughts <| sep |> So far I only have USB C to USB A adapters . I connected my Apogee Duet and an External HDD without any issues . Tested the Duet ' s latency and it seemed extremely functional , even down to a buffer size of 32 samples . As for the strip along the top , I really like it . It displays helpful information such as word suggestions , Safari bookmarks , and Mac functions . I haven ' t used it a large amount but I could see it having some extra functionality in the future if developers build for it .
