Bluetooth is built in; you can access it via System Preferences to pair the keyboard, etc.
What year is your iMac? If you don't see a Bluetooth Pane in System Prefs, yours may not have it built in (most do, but there are some models that do not),

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.
