I bought my elderly father a refurb all-in-one desktop Mac a couple
years old. It didn't come with the OEM keyboard but some kind of kinda
crappy Shenzen-special "wireless" keyboard. I assumed it was Bluetooth
at first but there's no dongle anywhere in the box, or instructions.

So you put in the AAA batteries, flip the "on" switch and power up the
Mac and nothing happens, the "wireless" keyboard and mouse don't do a thing.

I'll get him something better ASAP but in the meantime wtf do you do
with this thing?
