USB-C ports broken after 11.2 update

Both of my USB-C/Thunderbolt ports on my M1 Mac mini have become completely unresponsive after installing the macOS 11.2 update today.


I had a USB-C to DisplayPort cable in one and a USB-C hub in the other, neither of which now functions.


Both USB-A ports, the Ethernet port and HDMI port are functioning fine. Anyone come across this or have any ideas on what I can do? I've run the diagnostics tool to no avail.


Thanks in advance for any help.

Mac mini, macOS 11.2

A strangely dismissive and borderline aggressive response. I've been on the phone (for a total of nearly three hours in the past two days) with Apple; various senior advisors running tests, submitting logs and sending as much information as possible to engineers as they try to diagnose the problem and help.


More and more people are reporting the issue now across this board and elsewhere on the web. Luckily I have other computers I can use so I'm trying to be useful.


So no, they haven't 'asked me not to do that', but they've also not recommended a warranty repair yet simply because they have yet to actually correctly diagnose the problem that needs repair.

Well, sorry for not sympathizing, but taking it for Apple warranty repair is an option that’ll get you real progress, possibly even a swap with a new mini. It’s also an opportunity to have your issues independently verified hands-on by Apple, something logs and testing can’t do.


As of now, at least part of the problem description is hearsay and it’ll stay that way until Apple can take a look at your machine first-hand. So, haul it to Apple, they’ll take it from there, you’ll get much needed action. Good luck!

Fruit = no chance of that, unfortunately. Polite, well-meaning conversations and collecting logs - as many as you want (or tire of). As for taking the mini for warranty repair, do first go through the motions of setting up an appointment and screenshot/store mail if Apple don’t/won’t give you options. That’s to make sure the warranty clock (especially the 90 day one) doesn’t run out. All the best.

Could be, but it’s not a problem across the board (even if the Internet tries to whip things up). The update could merely have been a trigger to a pre-existing problem caused by a combination of stuff specific to some machines.


At any rate, since Apple now has its hands on the problem machines, they don’t have to go by posts here or Reddit or MacRumors anymore. They’ll get to the bottom of it, rest assured, meaning future updates will be brick-proof. Enjoy...

Rang Apple support yesterday, had a long chat with one advisor, tried starting holding down power button, then restarting normally, obviously none of this helped.


Then escalated to another advisor, he looked at screen shots, as my VGA dispaly works, but not properly, (the monitor has a floating box saying "input not supported", but desktop shows cut off to the left, and image is scaled incorrectly, downloaded logs and all that, he just said the 11.2 update was supposed to cure previous problems people had had, but ended up causing problems for others. Obviously Apple are aware of this, and a fix is on the way... in the meantime back to my old windows 8 pro suface ;(, connected to my display via an Apple mini HDMI to VGA......

Not a good idea. Phone staff are trained to be agreeable, going through the motions to show sincerity, helpfulness etc. But otherwise they're generally clueless and also powerless except for the simplest of problems.


I wouldn't wait for a fix that doesn't exist, instead return the mini ASAP for warranty repair/refund. Remember, there's a $clock$ ticking on that one. For promised fixes made over the phone, you could be waiting forever, also run out of repair/refund options. Just do it. Good luck.

Yes I am in the UK, so am prepared to wait a little longer for a software update to fix the issue.


Obviously advisors are trained to be pleasant, I wasn't expecting miracles, just to get the issue logged and fingers crossed a solution.


If I was solely dependent on the mac mini for my computing needs, I would be in a pickle, but as I am not, I am happy to wait for a fix before going through the ball ache of sending it back for a refund.


Although interesting point of consumer law, what happens if you by a product, that is advertised to work with your existing peripherals, it does just as described, then after a software update, it doesn't any more. How long would you be entitled for it to work as described? 90 days, a year, 5 years, in perpetuity?

You’re assuming there’s a fault with 11.2 that Apple will fix - as of now there’s no official basis for that. Meanwhile, others are already well into return/repair/refund. So, for most purposes this problem, which has affected only a minuscule fraction of all users, is now history.


Separately, delaying reporting a fault for warranty repair could place the warranty at risk. Essentially, it prevents Apple from independently verifying the problem, just so you’re aware..


As for your question of law, the fault you report hasn’t been isolated or replicated, it’s limited to hearsay accounts by some users and may well have pre-existed silently before the update manifested it. So really, there’s nothing to discuss on the law aspect. You have a warranty that Apple will readily honor or polite phone calls that’ll go through the motions but yield nuthin’. The former is the only option that’s time-bound and legally tight. Easy choice, huh? I’d just do it.
