    Hi all! My Magic Mouse 2 and Magic Keyboard 2 have not worked properly ever since macOS Sierra. I have had input lag and issues with connecting/keeping a connection. They work correctly under El Capitan, and have no input lag on unsupported versions such as Mavericks and Mountain Lion. I have tried resetting PRAM and SMC, and I have used the Magic Mouse at the Apple Store on an iMac and it seems to have input lag as well, though not as bad as mine. Does anybody have any issues with theirs? Thanks!

    Test in safe mode, you likely have some utility or app running that impedes their function.

    Tried that and it still isn't as smooth as El Capitan. Also ran the extended hardware test with Apple Hardware Test and it did not come up with anything

    Methinks Sierra messed up the Magic Mouse... less accurate cursor movements and scrolling issues. I'm running 12.2 and MM2 with bluetooth 4.0.

    Hoping an OS update fixes this.

    I've only had the magic mouse for a couple days, but it doesn't feel as precise as the trackpad.
