doesn't work on my macbook air 2013 after upgrading to El Capitan...im not sure if I recollect this well, but I think it worked on the 1st day after upgrading but stopped working after that...

macbook doesn't detect it in network preferences either...someone please help

used to work perfectly on OSX yousemite...

Btw I never had problems with this, because its basically PLUG and PLAY and has worked that way since 2.5 years over multiple OS from apple...


someone please clarify....or maybe my adapter stopped working :/

TB ==> thunderbolt

Go into software update, refresh with ⌘ + R, and see if you have any updates.

Then go to  > About this Mac > System Report > Thunderbolt

If your adapter is not showing up there, it might be broken.
