It’s very lightweight, it has a long battery life, and the keyboard and touchpad are outstanding. If you take your laptop to a different TV you will have to do it all again so be warned.There are a lot of reasons to like your MacBook Air. On my Aug 2011 MacbookPro I had to do ALL of the above. You may have to do some or all of the above to get sound out of your TV from your computer using the DisplayPort to HDMI cable. You will now have sound coming out of your TV from your computer 🙂 If you still cannot hear sound, log out of your account and then log back in. Make sure that sound output is selected and that you can now see a speaker icon next to HDMI in the list of devices. If you CANNOT see a speaker icon next to HDMI in the list on the left, do the following:īottom left of the window select the wheel icon with the down-pointing triangle. This last action below is NOT described in the iWires notes but was required in my case, it may also be required in yours. In the middle of the window, on the Output tab, where it says 'Source:' select your TV from the drop-down list. On the left-hand side of the window you should now see HDMI. Using either Finder or Launchpad go to Applications > Utilities > Audio MIDI Setup. Select your TV from the drop-down list next to HDMI, below where it says 'Select a device for sound output'. Middle of the window select your TV where it says 'Play sound effects through:'. Be sure you are on the Sound Effects tab. There are 3 tabs in the window Sound Effects, Output and Input. leave all other settings at their default values. Select the desired resolution for your TV (probably 1080i). You should now only see 2 tabs, Display and Color. Bottom left of the window tick 'Mirror Displays'.

Most people don't read this as it's normally the case that when you plug a cable in to anything it just works (VCR, TiVo, Xbox, video camera etc). If you purchased an iWires cable direct from Apple the instructions are in the printed booklet that comes in the packaging.
