I just upgraded to macOS Sequoia 15.1 and now my MacBook Pro and MacBook Airs do not recognize my Apple Thunderbolt monitor. Airs are running M2 and M3 chips.
MacBook Air 13″, macOS 15.1
I have solved my issue. Thankyou tbirdvet!!!! I have a MacBook pro M3 and like others The thunderbolt display ceased to work after upgrading to Sequoia 15.2. As suggested, I disconnected the power for a couple of minutes and plugged it in and at the same time I disconnected the thunderbolt display’s built-in cable and replaced it with an old style thunderbolt cable. It’s working beautifully. Either the power recycle worked or I had a bad built-in cable from the thunderbolt monitor. Again thank you all and tbirdvet.
@A Brody,
My monitor is black - there is no video - the audio works fine
@b travan,
I can't find your post on the thread, after reading it in an email. Please start a thread of your old.
See my reply above, I was asked to re post.
