Unusual charging indicator and auto-boot behavior on MacBook Pro 2024

I'm having an issue with my MacBook Pro 2024 when the charger is plugged in, where the charging indicator lights up with unusual behavior:

- If the battery is full, the indicator lights up green, turns off, turns orange, and then goes back to green.

- If the battery is not full, the indicator stays lit in orange without changing.

- The device turns on automatically when the charger is plugged in, even if it's off.

- I tried disabling auto-boot when the charger is plugged in with the following command:

sudo nvram AutoBoot=%00

But it didn't work, and the device still boots automatically when the charger is plugged in.

the battery charging scenario you paint seems normal.

charging can be put on hold

you can compare these Terminal command vs what you posted above...

Be careful using any NVRAM commands on an M-series Mac as some of them can prevent an M-series Mac from booting.

Most of the commands you will find are only intended for Intel Macs. The only "nvram" command that I know is safe for an M-series Mac is the one used to clear the NVRAM settings or to delete a specific NVRAM item key. Setting any NVRAM values will most likely cause problems unless you know with certainty that a particular key/value pair is valid for an M-series Mac. Here is the command to clear NVRAM settings (safe for both Intel & M-series Macs....must add "sudo " to the beginning if used while booted into macOS, otherwise the command listed is for use while booted from a macOS installer):

nvram  -c

FYI, unfortunately there is no way to change the auto boot behavior of the M-series Macs. You can always provide Apple with product feedback here (Apple won't respond):

I missed that link earlier, thanks for hitting me with it again ;-)

That change is definitely nice to see & most welcome. It is also interesting how much Apple is resorting to the command line these days to configure & customize macOS.
