I recently purchased a secondhand a 27 inch thunderbolt display to connect to my Mac mini M1, initially it worked and then it went black I’ve been searching all over the Internet to find out what the issue is
it is connected with a Apple thunderbolt 3 to thunderbolt 2 adapter it no longer powers on I’m confused on what I should do
I agree with D.I. Johnson -- it is hard to assess what's the problem, and hope you did not spend much money on it.
But, I am going to offer my 2 cents:
There might be few more possible issues that you have to ask yourself - is it worthy to invest further or, find another one (reputable with warranty).
Good luck
Please use Apple's TB2 cable (0.5m or 2mm) if you can.
I found some 3rd party TB2 cables can be problematic.
Again, as I mentioned earlier - it can be the octopus cable or power supply, or.....
Here is a little visual that might be interesting to you..
There is another TB2 port that can be utilized with male-male TB2 cord, to see if the problem is the octopus cable.
Good luck
I believe you’ve discovered why the Thunderbolt display was on the second hand market.
This sounds to me like a power supply issue. I think you’re back in the market for another display for the mini.
I own an Apple Thunderbolt Display and had the built-in TB cable fail several years ago. The display started to "wink" and eventually stopped altogether. I picked a a Thunderbolt cable and plugged into the open Thunderbolt port and has worked fine ever since.
thank you so much for the visual!
i picked an apple cord up and will tey it this evening 🤞🏾 fingers crossed
I have a TB display and works fine. As already stated it may be the octopus cable. Try getting a TB2 cable connected directly to the TB port on the display.
can you explain this? not sure where and what cables you are referring to
can you further explain this?
You do not need to use the integrated TB cable. You have a TB port on the display. Get a TB 2 cable and connect to that port and connect the other end using the TB 2 to TB 3 adapter to your Mac
thank you i will try this today
this worked!
this worked! thank you so much for your help
I used an external TB cable to adapter to Mac Mini and it works
