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!
