USB-C ports broken after 11.2 update

I don't allow my Mac to sleep just the monitor which does sleep. I don't care to have my monitor active when I am not using it. Especially in my bedroom where I sleep. Seems ridiculous to change my needs just because an update caused issues?

Same issue here. Both of my ports are completely useless. I bought this Mac Mini specifically for dual monitor since Apple killed that important feature on their MB Air M1 and now I am right back to one monitor. FIX THIS APPLE!

I hate it. I absolutely hate it. Spent $1k on this machine only for apple to push an update that completely disabled the thunderbolt ports.

Apple Support was no help and told me they'd get back to me in about a week. Unacceptable IMO.

Brought it in and they have taken it as returned and do a refund. I asked if possible to ordered it again however make sure the OS updated to 11.2 or later and making sure the ports all working. The genius said if it's a serious issue we should as we an update very soon. 🙏🏼

Good move! Update may well be pre-installed in a new machine (wait a month or two before ordering) or it should install painlessly as a first step on a brand new mini (don’t migrate/setup more than minimal). You are ahead of the rest, congratulations!

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...

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?

Al.

I have just had my two USB-C/Thunderbolt ports on my brand new M1 Mac mini fail when they were working fine earlier today. I have Big Sur 11.1 OS. It seemed to fail after I plugged in a USB-C multiport adapter.

Has anyone had success with multiport adapters?

This is the beauty of M1 Macs, you can downgrade firmware with AC2 and DFU mode!

In this situation with no USB-C ports that will be impossible. I will test now to see if using the installer downgrades the firmware or not.

No, they'll most likely push a firmware update in 11.3.

Do you understand how binary values work in terms of providing power from circuits on a board through bus channels? Do you understand how these binaries change with firmware updates?

If not, please stop giving users information. In fact, please just stop posting all together, you're annoying.

Hahaha! Well, since you know all about binary, your choices are either fix with repair or wait endlessly for a problem that existed prior to 11.2. Good luck!

I agree with you, sort of,. but the two choices should be Apple Store

for repair/replacement or request an RMA to ship the return for repair

or replacement. If it were mine, I would not be hesitating at all.

A very similar thing happened to me yesterday.

New M1 mac mini arrived yesterday.

I set it up with my Apple Thunderbolt display and attached my Apple USB keyboard

I did a completely fresh install (not from a backup).

Then I was prompted to update to 11.2.3

Following the update my Wired Apple Keyboard failed to register - and I'd not yet paired a bluetooth backup!!

The keyboard still worked absolutely fine on my 2012 MBP - it also worked fine on the USB port of my Thunderbolt display (connected to the new mac mini).

Other USB devices (including a non-apple USB keyboard) also worked fine.

Touching the device showed masses of static - it was really really tingly!!

I'm going to do a fresh install again today and update the OS without installing any other apps and see if I can replicate the issue.

Apple phone support were very helpful.

Luckily this is still within warranty, so I'll take it back if it continues to fail.

I have exactly the same symptoms..after update 11.2

I'd appreciate it if you could go get the service and let me know if this is a real hardware problem or a software problem.
