How to Connect Cable TV to an iMac
By James Clark
A cable TV set-top box with a digital FireWire jack can connect to an iMac computer for watching TV programs. Apple TV software on the iMac lets you process audio and video signals from the cable box through the FireWire cable. These digital data cables are available at electronics and computer stores. Connecting the cable box to the iMac with a FireWire cables takes less than a minute.
Plug in the FireWire cable to the port on the cable TV box. The connector inserts in one direction only, so you may need to turn the connector to fit the port.
Hook up the plug on the other end of the cable to the FireWire port on the back of the iMac monitor.
Click "Finder" and select "Applications" to choose "Apple TV," which will launch the television application on the iMac for viewing cable TV programming.
