In my Mac Book Pro (10.6.8) the time machine (TM) was 1.5 years ago configuered to make back ups with Time Capsule (TC). However, now I do not have/use the TC anylonger. How can I configure Time Machine (TM) to make back ups with an external hard drive (USB, 1TB)? When I click on "choose back up volume" on TM the one and only option left is to "configure time capsule" - which does not exist anylonger. It only recognises the non-existent TC and not the USB external HD. When "configuring TC" it searches for wireless airport, which I also do not have, as I'm sharing/using my neighbour's internet connection. How can I make the TM to recognise the external HD?
