Please tell us exactly which model MacBook Air you have. It would be good if you could do About This Mac (under the Apple logo in the menu bar), then press "More Info" and tell us what it says at the top.
The reason for this request is some of the older MacBook Airs, while they have ports that look like Thunderbolt, actually came out before a full Thunderbolt capability was introduced. Tell us which MacBook Air you have and I'll check.
Thanks for this info.
Indeed you do have a real Thunderbolt port as shown here:
... so my fear and resulting explanation does not apply. (That's good news for you, I think.)
Sorry, this leaves me perplexed.
Hi, how did you solve your problem? Im having the exact same issue.
"When connected to the TV via the Thunderbolt-HDMI cable, a blue screen briefly appears on the Macbook. However, when looking in System Preferences/ Displays, there is no trace of any external screen. Many of the forums I have read say there should be an "Arrangement" tab, but this is not appearing on mine."
plus the cable works on my boyfriend's Macbook Air, which is an older version than mine.
I have the Macbook Air Version 10.8.4, bought July 2013 (newest version).
Can someone help me?
