Hello, I have a MBP 2010 17". Recently I bought a BT keyboard. I tried to pair it with my MBP 2010 (under both Mac OS and Windows) but it did not show up as one of the BT devices available. Don't know if iPhone can do it but as a test, I tried to pair it with my iPhone but it was also not found. Is it a problem with the keyboard or there is a compatible issue between my old 2010 MBP and a relatively new BT keyboard? Are all BT keyboards supposed to be able to pair all BT available laptops regardless of BT versions?
