MBP retina 15" 2012 model Thunderbolt connector...

I am not sure if anyone noticed. My MBP 15" retina 2012 model thunderbolt connector is kind of loose. It's hard to describe the feeling but if I connect ethernet connector while my computer on my lap, connector will be unplugged if I move a little. Not only this, I am unable to move my MBP a little if I have my 27" apple display connect to it. I never have this kind of problem with my old 17" MBP.

I took it back to apple store and had the connector board replaced. It plays just a little better but still having the same issue. I kind of tested 2 MBP in the store all happen the same. I was told there is nothing they can do about it in apple store. I wonder if anyone has the same problem.

thanks

I have the same problem.  My Thunderbolt Ethernet is useless.. it rarely stays connected. If I bump my desk the screen flickers from the loose fitting Thunderbolt DVI adapter.   I am going to send my MacBook Pro Retina back to Apple and see if they have a solution as it's just not acceptable.  Total design fail - maybe time for a recall of the whole range?

I'm having the same issue - ethernet adapter is impossible to use and connection to any external hard drives is unreliable enough as to render a backup impossibe. Please let us know if you find a solution.

I really suggest you to bring it back to store and address this issue to Apple. The new logic board that they replaced for me did not do the job well so it looks like the manufacture who made that connector mess things up. I had them to create to trouble ticket for this but I doubt they will ever treate it seriously.

I believe not a lot of people notice this issue because thunderbolt is not that popular for now. I hope more people bring this issue to Apple so they can start correcting this problem.

Same issues here I actually justed posted a post about it, it is very anoying as not only the ethernet keeps disconecting but alos my drives and i do quiet a few live broadcast the video feed coming into the computer keeps disconecting. on the last video broadcast I had to use electrical tape and taped the connectros on the computer and that helps a little. But sometimes just a little wiggle on the connector whithout even removing it disconects the hard drive, video or other device on that port. I have to say sorry for that money we paid that should not be a problem at all , looks like someone got the messurment wrong.

For example on my Gdrive the same cable fits nice and snug and you have to tug for it to come out and it does not wiggle left to right at all. Maybe apple should get their messurments

on another note my SD card reader stopped working as well plus my screann has about 15 dead pixles which means I have to mail it in for repair and have not computer for about 2 weeks or so

Same problem here. Happens mostly with a dual-link DVI to mini-display port adapter, but also with other adapters as well, including the ethernet adapter (all genuine apple products, not 3rd party).

yep, same problem here....it makes it absolutely useless for using at gigs with my firewire sound card (connected via thunderbolt -> firewire adaptor), the **** thing wont stay in place with even the slightest movement....total fail apple, all in all this mbp retina has been the worst quality mac ive owned yet (other problems like slow scrolling, screen burn in, dead pixels &trackpad issues have also popped up from time to time)

I have the very same problem with a new work MBPr. Tried several TB connectors for Video and Ethernet all wobble and intermittently drop connection if the cable is moved slightly or if you move the machine. The network bouncing is causing white screens. On a colleagues Air the same connecters do wobble but don't cause the problem. This says to me it's an issue with the machine. Using USB network in the meantime, the IT dept here are sending it back to Apple for a look. Very poor build quality!

Fixed! Try reseting the PRAM - it worked for me. The connectors still wobble but do not lose connectivity.

Thanks Darren26.

Can you describe the steps to reset the PRAM?

I have the same problem. My computer was replaced. It worked just a bit better during the first week but quickly degraded. It is obviously a design or manufacturing defect. I hope apple comes up with a kit to resolve this critical issue.

Thanks for sharing - gave this a crack by no luck.  My Thunderbolt connector actually has burn marks around the edge, so definitely a hardware failure due to short circuits from a loose connector - rather than a firmware/software issue.  The connector is totally dead now, which makes me think something has burnt out on the motherboard or the connector is fused dead.  Woeful design fail Apple..  I've only used Apple official DVI and GigE adaptors in the failed Thunderbolt port.  My remaining, still functioning port works but only if the GigE adaptor is dead straight and pushed in firmly.  Move the MacBook slightly and it disconnects from the network.  Very very frustrating, hopefully they rethink the design of the Thunderbolt socket in future products.

I can confirm that this issue can be resolved by resetting PRAM.  Thanks DarrenR26 for the correct solution. Thanks clintonfrombirmingham for giving the link showing how to reset PRAM.

Although the thunderbolt seems loose,  this issue is actually a software flaw. I called the apple care , asked them if this is a known issue,  they didn't give me the right anwser, they just say that I should bring my macbook to them and they will examine it.

This should be an issue that apple have noticed, and their apple care service should give their customers the suggestion.  

Congrats on finding a solution to your problem, but I doubt this will work for most of those here. I've reset NVRAM (PRAM is for older, PowerPC Macs) a few times for other issues since I first noticed my Thunderbolt port losing connectivity if jiggled, and that problem has remained consistent.

Just yesterday I reset NVRAM to help diagnose an issue with my screen, and can verify that the port that has been a problem still loses connectivity with my Apple Gigabit Ethernet Adapter, Apple DVI Adapter, and Apple Dual-link DVI Adapter.

Therefore, for myself and most here, this is not a software issue. Anyways, a software problem wouldn't explain something that occurrs when a cord is jiggled. Unless there's some sensor that is reporting to the machine that the signal should be cut even though a connection could be maintained, which wouldn't make any sense.

Good to know that some, however, might find some level of solution by resetting NVRAM
