After upgrading to 12.4, my 2021 16-inch MacBook Pro w/M1 Pro CPU now doesn't charge from any USB-C ports. My usual USB-C charger stopped working and the MBP doesn't make a beep or indicate any reaction to the charger. I've tried another charger and cable that I know work. It will charge from the 140w supplied charger but not from USB-C?
MacBook Pro 16″, macOS 12.4
I have the same issue too. I have MBP 16 Pro Max. Which chip do you guys have? Pro or Max?
For my instance, normally it'll happen after I folded down the screen (without powering down), and re-open the screen. Both sides of USB-C ports will stop functioning. From what I read, there is no manual SMC or PRAM reset on these M1 machines. So I shutdown, power off the laptop completely. Close the screen and wait for at least 1 minute. Re-open the screen and ports are back to normal. But it happens daily so it's very annoying.

My 14" has done this twice now. Connect my Studio Display to the right side port and no picture or charging. Today my USB C ethernet adapter wound't work on either side. A restart has fixed it both times. Hope the SMC reset fixes it permanently so I don't have to wait for Apple to admit something got broken in 12.4.
The SMC button combination did something, even though it's not a M1 thing?
Restart your MBP and see if that helps.
Just posted today, by someone else, in MacRumors forum:
"Brand new 14" MacBook Pro M1 Pro 32GB macOS 12.4. Successfully charged to 100% for a few days. Left it plugged into the MagSafe 3 for a couple of days and was shocked to find it at 38% this morning. MagSafe was glowing steady amber but the Mac showed "Power Source: Battery". Battery health is normal and capacity is 100%. Plugged into a different charger via USB-C, no change. Restarted, no change. Shut down, waited for a minute, booted, now charging correctly with both USB-C and MagSafe 3..."
Exact same problem.
For my USB-C charging/access issue, after I did the Apps updates (few apps including Safari Tech Preview) with restart, then it solved the problem. Maybe there is something corrupted during previous updates
On my part, I first noticed that my usual USB-C PD charger and cable didn't work. Then I took the charger and cable out of my laptop bag and it didn't work. I restarted with no joy. I have a battery app that tells the condition of the battery and the charging rate. It confirmed that the MBP wasn't accepting a charge. I then dug out my original charger and used the MagSafe port to charge it. Using the same brand USB-C PD charger at my home office, it suddenly started charging. Now the first USB-C charger now works.
Apple told me to file a bug report here: Product Feedback - Apple. Maybe others can help do this too to get more visibility on this issue.
I think this can help to escalate the problem to the software or hardware engineers that might be able to fix this bug introduced by 12.4.
It's a known problem with 12.x and will often fix itself. My charging issue lasted one day before it somehow repaired itself?
Try the obvious and restart the computer.
Also assuming the charger and cable previously charged the MBP then turn the connector upside down and see if that helps. Some USB-C cables are not fully wired in both directions and are missing some connections.
Restarts seem to be the only thing that sorts the issue out for me, and it may be weeks, days, or even just hours before it reoccurs.
I have also had more frequent panics than I'd expect - I'll pay attention to see whether there's a USB-C charging association. I usually don't close the lid at night, so mine just looks like a refusal to wake from "sleep" in the morning.
+1 Restarting fixes the issue, but after the computer is unplugged for a bit, then plugged back in, the computer does not recognize the usb C charging. This also affects my ability to extend displays with my usb C hub, since USB C port is essentially broken, it does not recognize my external monitors.
While I can't immediately find the Apple page I was thinking of, the link below is to a review on optimized charging.
How to Turn Off Optimized Battery Charging in macOS - MacRumors
If you look at #3 and read the screen it says "To reduce battery aging, your Mac learns from your daily charging routine so it can wait to finish charging past 80% until you need to use it on battery."
That's what I'm saying, the laptop will charge to 80% BUT when it thinks you are going to use it then it charges to 100%. The 80% your talking about is BEFORE the laptop fully charges. "TO REDUCE BATTERY AGING" is what I'm talking about.
Still getting random dead USB-C ports since upgrading to 12.4. Restart remedies it, but only temporarily.
I'm not in the habit of spending $3,000 and then trying to figure out how to make something perform its basic functions. Unless they fix this before my return window closes this 2021 16" MacBook Pro goes back.

If you're sitting at home waiting for some fix to magically happen, you'll likely be disappointed. You're assuming this is a universal problem. It's not. I've no issues charging my MacBook Pro via MagSafe or USB C on MacOS 12.4. I suspect most people don't have an issue or this thread would have blown up, which it hasn't. Schedule an appointment at your Apple Store Genius Bar and let Apple see your device. Or return it if you're not happy with it. That's really up to you.
One Note: If you are running ANY antivirus or scanning software on your MBP, uninstall them. Macs don't need antivirus software and they often don't work well on Silicone-based M1 ARM computers. They can cause all sorts of issues.
I believe that there are enough instances of this occurring for Apple to know about it and like most companies are reluctant to admit a problem. I know a number of us have filed an issue with Apple tech support so hopefully getting a 3-year warranty is not going to be money wasted.
The USB-C issue seems to correct itself for a number of users, mine included, which tells me it's not something permanent. It could be an interaction between objects in the operating system that could somehow self-correct. Plus since the problem started in ver 12.x, it seems to indicate that a change/addition created the issue.
Keep in mind if you have Optimized Charging checked (the default), the computer will not charge past 80% if it thinks you're going to keep it plugged in. So check the battery level before thinking that it's not charging. If you click on the battery icon, it should say that charging is delayed if this is the case.
Also try turning the USB-C connector upside down and plugging it back in to see if that makes a difference. Some USB-C cables are not fully wired and may not charge if plugged in backwards.
A lot of people, including myself have had issues with USB-C not charging but it seems to be intermittent. Be sure and upgrade to 12.4 if you haven't.
