Recently I'm using my MacBook Air mostly in clamshell mode, with an  Wireless Keyboard and an  Magic Trackpad paired. Sometimes, weeks pass by without even opening the lid: connecting it at the office, putting to sleep, connecting it at home etc.

From time to time, the bluetooth keyboard does not connect back on wake automatically, as the bluetooth trackpad does: I have to open the lid, type in my password, then pair the keyboard to use it.

What is the problem and how can it be fixed?

  • Do you have any other devices in the house that this keyboard could be connecting to? – lennard Jan 4 '12 at 22:27
  • I might suspect my flat-mate's MacBook, but the keyboard has been paired since day one to my laptop. Shouldn't that prevent it from being "hijacked"? – Marius Butuc Jan 4 '12 at 23:05
  • it can still cause the problems. If your laptop is off and it connects to his first then it will never connect to yours. It does not matter if it was paired to yours first, if its also paired with another machine it will connect to which ever one is turned on first. – lennard Jan 6 '12 at 16:22

Resetting the SMC should be able to fix the issue. Note that this will reboot the MacBook, so you will lose any unsaved work.

  • Shut down the computer.
  • Plug in the MagSafe power adapter to a power source, connecting it to the Mac if its not already connected.
  • On the built-in keyboard, press the (left side) Shift-Control-Option keys and the power button at the same time.
  • Release all the keys and the power button at the same time.
  • Press the power button to turn on the computer.

Note: The LED on the MagSafe power adapter may change states or temporarily turn off when you reset the SMC.

This seems to be the goto answer for a lot of Mac issues. I can attest that the only way to get your magic keyboard to auto-reconnect on a MacBook Pro running the Mojave is actual magic. I've reset the SMC, tried multiple laptops, and attempted every avenue of this and I simply ended up plugging it in half the time.

The issue seems to relate to the way it handles Bluetooth. If you turn off the keyboard turn on they keyboard and press any key you have a greater chance of success. However, you'll sometimes notice in bluetooth settings that it'll try to connect on and fail over and over again. This will flash until one side gives up or you get the Bluetooth error saying bluetooth failed.

The last and best option that I tend to use is in the morning I'll remove the keyboard from bluetooth settings OR keyboard settings. Then tap a key and add it back and I tend to get most of a day of working wireless.

I strongly suggest submitting a bug report to Apple to show that this is an issue so they can ignore it just like mine :) https://developer.apple.com/bug-reporting/

Good Luck!
