Thanks for helping. I use Apple's usb-c to Thunderbolt adapter which I bought from Apple's store. The display is detected. I can use it with MacBook Pro properly when I turn on my notebook. However, after some time, the display just goes black but the camera, speakers, and all the windows (for example, Safari's window, etc) are still open on the display. I know that it is still there because I can move my mouse to the Thunderbolt display from my MacBook's display which are connected as extended display (and when I set that windows to appear on the MacBook's display, it appears again but the Apple Thunderbolt display is still totally black out). So, I know that it is still there but it just blacks out.
Just to give further details:
- Before I upgrade macOS, the display is not all the times detected, i.e., sometimes when I turn on my MacBook the Apply Thunderbolt display is detected, and sometimes it is not. Or, sometimes while I use the Apply Thunderbolt display, it is just suddenly not detected and goes off. The speaker, camera, and all other devices that are daisy-chained via Thunderbolt cables do not work.
- After I upgrade macOS to 12.3.1, it seems that the problem of not being detected is solved. The display is etched every time when the MacBook is turned on. However, it becomes that it can go black out but is still detected as I explain above.
At this point, I am trying to find out what I should do. My question now is :
- Should I try to reset the SMC as I have seen some posts suggesting to do so. Would it help?
- Should I just contact Apple support to solve this issue.
