16-inch MacBook Pro users reporting MagSafe issues, clamshell mode problems
For some users, the new 16-inch MacBook Pro does not always charge when completely shut down, and others are dealing with external monitors not waking correctly in clamshell mode.

MagSafe charging on a MacBook Pro
Some users of the revised 16-inch MacBook Pro have been reporting hardware issues concerning MagSafe charging, and using external monitors.
Initially reported on Reddit, the first account included a video showing what happens when user "Trillionaire" is attempting to charge. With the M1 Max MacBook Pro completely shut down, the MagSafe charging connector flashes orange to indicate that it is not charging correctly.
According to "Trillionaire," Apple support staff are investigating, and say that "Apple is aware of the issue." Apple support recommends that users:
Separately, users on Apple's support forums have reported issues with using external monitors. Some issues concern use of external monitors on any Mac under macOS Monterey, but others specify that it is the new MacBook Pro that's having problems.
Typically in these cases, what is reported is that external monitors are not reliably waking up after a MacBook Pro lid is opened and closed. AppleInsider has not been able to reproduce either issue, and it is not yet known how widespread the problems are.
As with other similar issues, we recommend starting a support case with Apple, should the problems manifest locally. This not only protects the user should the problem be more serious than originally though, it also provides Apple with additional data points to triage accordingly, and to solve the issue.

- Charge the MacBook Pro while in sleep mode
- Charge the MacBook Pro with the lid open
- Attach the MagSafe cable, before shutting down the MacBook Pro

Haven't noticed the charging issue, though I charge mainly through the dock anyway, and I guess the issue is only with MagSafe?
Apple were pretty quick about fixing the Safari lockup issue, so hopefully they'll have a fix soon.
Seems like both of the issues reported in this story are likely software issues rather than hardware and should be fixable with an OS update.
MagSafe cable still in box w/the brick.
May test, just to confirm I don't have these issues.

I open the cover and it starts charging correctly. Guess I will have to live with it. I have the newest updates.
To stop the peeping. On my M1 Mac book Pro, when shutting down wait till the key board lights go out before closing. If you don't I think it goes into sleep mode.
To date there have only been two versions of Monterey.

"It’s been a couple of months now since reports began to appear of M1 Mac users experiencing excessive SSD usage. In the worst cases, users had already reached 10% of the rated endurance capacity of their drive within 2 months"
"I could expect my M1 MacBook to pass that (EOL) threshold after exactly 1 year at current usage"
