USB-C ports broken after 11.2 update

I have had a similar problem, but not the same.

Display not working properly after 11.2 update.

Plugged in to USB-C port, to VGA adaptor.

Al.

Have you tried resetting the SMC and NVRAM?

If you have a Bluetooth keyboard, you may need to connect it to a USB port on the Mac.

There is yet another option if you have access to a fairly recent

second Mac.

The Configurator 2 app now has the capability to "revive" an M1 systems

firmware, i.e. re-flash. Perhaps there was just a borked firmware install

and reflashing it may fix it (system hiccup, phase of the moon, etc.).

Just stick with the "revive" portion unless you really want to wipe and

start all over.

Update to my case.

Brought my M1 Mac mini to the Genius Bar yesterday, and explained the case. They called me later that night to say they were unable to fix/diagnose the issue, and we had essentially two options:

1. Downgrade from macOS 11.2 to 11.0.1 to see if that reactivates the USB-C ports.
2. Order a new logic board (which they say likely would take about a month to arrive, as this is an M1 Mac and parts are harder to come by right now.)

Ultimately, we ended up ordering the logic board, and I took my Mac mini home for the time being. I'm hoping that Apple catches this and issues a fix ASAP, or that one of the press/tech sites picks up word of this issue so Apple catches wind of this a little faster. I'm fortunate to have an HDMI monitor, but for folks who rely on a thunderbolt connection, this sucks. I'm definitely hurting being without my thunderbolt dock right now. 😅

After powering right down and trying a diagnostic test, I plugged my other dock into the USB-C port and the dock works fine, but my monitor still won’t work through the USB-C port. HDMI does work for the monitor though.

This sounds like breaking news in more ways than one...

Say it ain’t so? Because if it is, Apple has a **** mess on their hands. Thankfully nothing changed on the Intels (nothing needed fixin’ for me and nuthin’ broke, whew).

FWIW, it hasn't affected my USB-C dock on my MacBook Air

(only has TB/USB 4 ports). Normally, in this sort of situation

I would suggest downloading and installing a Combo update.

However, in their "infinite wisdom", Apple is no longer providing

combo updates for macOS Bug Sur (no a very good move).

You could try re-installing from recovery which should download

the latest macOS version or download the full version from the App Store.

I noticed my 2018 Mac mini has a minor display issue coming out of sleep after update. The monitor wakes but then briefly goes black again and then wakes again. I use a USB C to DisplayPort adaptor for my monitor. This was not happening prior to Catalina 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?

Ah, I see, ignore that. But why isn’t your monitor on HDMI? I’m speculating that’ll fix it. Unless you’re after some special resolution (which 11.2 might have fixed), HDMI IMO is also better. Give it a shot?

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!

Having the same issue. Reached out to support to tell them that my M1 Mac Mini's USB C ports weren't functioning - although they were perfectly prior to the 11.2 update.

Aside from recovery (which I tried), reinstalling macOS (which I tried) and booting into safe mode (which I tried) - she didn't really give me much to go on. Just recommended bringing it into an Apple store.

... closest Apple store is a near 3 hour drive...

Nothing works via the two USB C ports - phone doesn't charge, keyboard isn't recognized, magic mouse either... Very frustrating.
