From the feedback it seems that the keyboard has a memory, which we need to reset, this is inside the keyboard itself, but how is this done.
Are Apple trying to say that if you buy a keyboard you can ONLY use it with one machine, and if it stops working with that machine, buy another one?
I have wasted several hours now, I am writing this on a friends laptop because I don't have a keyboard.

Hi Julian,
- I've got exactly the same problem with an iMac G5 Rev A (10.5.1): the Bluetooth assistant can see the keyboard under 'any device' but the type is unknown and it will not pair. The keyboard cannot be seen if 'keyboard' is selected in the set up dialogue. I tried everything (as did ProfT), even reset of SMU.
- Put your Bluetooth device into pairing mode. The exact method for entering pairing mode varies by device, though most automatically enter pairing mode the first time they are turned on. Click on the Pair button beside the keyboard you want to pair. Click on the Pair button beside the mouse you want to pair.

Sometime a Mac can't pickup the connection of a bluetooth keyboard or mouse is normal. Whatever your Mac is brand new or not.

I remember from a third party keyboard i used to have that unless I installed their driver, modifier keys did not work. At some point, they no longer issued updates, so none of those keys would work with a newer OS version. On their site, they claim to be compatible to 10.11.4. Which OS version are you running (you do NOT have iOS on a Mac).
I will do the following if the brand new Mac can't pickup the bluetooth connection, but make sure the bluetooth keyboard and mouse is not yet paired with other computer, that means you have to un-pair the keyboard and mouse from your MacBook before you perform the follow step:

- Switch off the Mac

- Switch off the Keyboard and Mouse which not yet paired with other computer, remove its battery, and re-install the battery after 10 seconds
- Switch on the Keyboard and Mouse first, make sure both devices have a green light flashes (the light flashed at intervals, like a pulse **...**...sorry my poor English), that means the devices is discoverable.

- Switch on the Mac asap if all the bluetooth keyboard and mouse is ready, and let the Mac pair both device (according the screen instruction)

If the method still doesn't work, the worst case is: i'm afraid you have to connect wired keyboard and mouse to finish the Setup Assistant, and pair both bluetooth devices by Bluetooth Preferences. Once both bluetooth devices connected, disconnect wired keyboard and mouse.
