MacBook Pro 16" (2021) M1Pro Charging issue?

To fix this currently you need to do the following:

System Preferences -> Battery -> Battery -> Disable optimised battery charging

Apple has confirmation that it is a software issue, it's being investigated and will likely be fixed in an update shortly.

The confirmation came from the apple engineering team communicated through the apple support advisor team over the phone.

The answer is to turn on the laptop, plug in the charger, then wait until the orange LED lights up on the MagSafe plug, then close the lid. That works for me and I've not bothered with fiddling with the optimized charging feature. I did have the laptop open overnight, split, on its side, but then noticed that the power consumption remained at 130W when the lid was left closed (but don't forget, you have to turn on the laptop first!)

My MacBook Pro M1Pro 16” (1 TB SSD) has this same problem. The battery was at 33%. I bought it less than a week ago. I turned it off for the first time and plugged it in to charge. It makes a beeping sound every few seconds, and the amber light on the charging cable blinks on and off. I found this thread and another on Reddit where a lot of people are having this same issue. I don’t think the solution is to replace your MacBook. The solution seems to be for Apple to make a fix. Apple, what do we do? These computers weren’t cheap.

Just bought the 16" MBP M1Pro and noticed when I "shutdown" the MacBook, close the lid, plug in the supplied MagSafe charger to the Mac, the MagSafe indicator light flashes amber and making a connect/disconnect sound from the Mac. Now if the Mac is powered on, charging works as it should. Spoke with Apple Support on this and they have no clue on this type of issue. Anyone else experiencing this issue?

Same exact issue with a new 16" MBP M1Max

Yes. I’ve had the same problem. Other people (here and on Reddit) have said their MacBook Pros beep when plugged in.

I found the solution for me:

Plug in your laptop while it’s still on. Then turn it off.

Fast-charging is an innovative new feature that works very differently from the standard way of charging. This is the first group of Macs it appears in.

When you are on technology's bleeding edge, some of the blood will be yours.

Hi All

Not sure if this will help but I contacted Apple Support on chat and they advised to put the MacBook in safemode, then boot as normal. It seems to have resolved the issue. Will test further when the battery is below 20%.

I had just finished chatting with the apple advisor they recommended me to wait for the fix in the mean time

charging the Mac while in sleep mode

charge the Mac using usbc port

connect the MagSafe before turn off the machine

In my case, the update worked for one night. The following day, after shutting the computer down and attaching the MagSafe connector, the problem was back. I had to leave my computer on in order to charge it.

I'm not sure what to advise in your case. Maybe you could try to apply the update a second time? (not sure if that is possible)

I have been testing this daily, and in my case the issue is resolved.

Thank God for the New update because i was seriously considering returning this thing ,due to this fault ...

the update fixed the issue .. the orange blinking light while trying to charge it and off with lid closed ..

I am experiencing the same issue! Apple did send a replacement laptop however, I am still experiencing the same issue.

I have contacted Apple on four separate occasions regarding this issue with no response.

I am very dissatisfied and disappointed with Apples lack of ‘customer and after sales service’.

Crazy but mine would blink orange while closed and off.. Would only charge while open and On. But once I did the update, it's fixed.....

Not sure if you've tried the update but it fixed this issue for me
