babowa thank you for your input. I bought this Imac second hand about a week ago. It is a massive lump with 32gb of ram and 8 cores and is about 2 years old I am running Mac OS Lion 10.7 - But I am new to Apple.
I keep getting a USB warning and thought I would move to wireless since the wired mouse and keyboard are too short.
BUT no sign of a bluetooth module, and like a newby I dont know what to do next.
Well, it should have Bluetooth, but, just to make sure:
Go to the Apple and click on About this Mac.
Click on More Info.
Click on system report.
copy what it says under Hardware Overview (Model Identifier, etc - not the serial #)
Then click on Bluetooth; you should get a similar screen:
Post back what it says.
