OK here is the scoop, my bluetooth on my iMAc would not send a file nor browse a device, though it would pair up with my cell phone for applications such as Blue Phone Elite2. Please advice me what might be the reason for file transfer and being able to browse for other devices via blue tooth fails. Up until now everything worked like a clock, the computer is now 2 years old, bought it in May 2007. Model Name: iMac Model Identifier: iMac5,1 Processor Name: Intel Core 2 Duo Processor Speed: 2.16 GHz Number Of Processors: 1 Total Number Of Cores: 2 L2 Cache (per processor): 4 MB Memory: 3 GB Bus Speed: 667 MHz Boot ROM Version: IM51.0090.B09 SMC Version: 1.9f4 If this helps. Thanks in advance.
