Currently using a 15" 2012 i7 16gb RAM MBP and realize that of course Apple Watch unlock compatibility isn't supported due to the lack of 802.11ac band support. However, MacID seems to do a pretty good job, and perhaps even better. How well does Apple Watch unlock work? MacID works with the iPhone and both the watch. Additionally, the computer will auto unlock and auto-lock when you leave the vicinity based on -dB. However, it does have its own problems with Sierra... Does the built in support work flawlessly without the need of an iPhone etc? Can you you use an 802.11 AC USB adapter to make it work? Is it an improvement even worth it? Thank for any input.
