16-Inch MacBook Pro Users Report Power and Monitor Issues

Are you having these problems with your new Apple MacBook Pro?

Apple’s latest M1 powerhouse, the 16-inch MacBook Pro, promises to be a great editing tool for filmmakers. Based on the Apple Silicon M1 ARM style processor, the M1 MacBook marks the return of Thunderbolt 4 ports and the patented MagSafe magnetic power connector.

But less than a month after being introduced, users of Apple's top-of-the-line 16-inch pro laptop are reporting issues with not only the MagSafe connector, but with the laptop’s clamshell mode as well.

According to a recent Subreddit on the M1 MacBook’s recent problems, users have complained that when connected by the MagSafe power adapter and having been turned off, the laptop doesn’t charge the laptop battery. 

“Recently I noticed that when the MacBook is shut down completely there is an issue with charging,” writes user Trillionaire. “The LED on the charging cable repeatedly turns on and off and with each time it does you can hear the charging sound effect. Is this a known issue?”

Trillionaire then reported talking to Apple, who stated they are aware of the issue. A workaround through recovery mode was suggested by Apple, but it proved only to be a temporary solution. The problem soon reappeared.

So, until Apple issues an update to correct the issue, it is suggested that users either charge the computer while in sleep mode or with the lid open. It is also suggested to attach the MagSafe cable first, before shutting down the computer. Another suggestion is to try charging via USB-C, as that port is not affected.

In a related issue, it appears that the 16-inch M1 MacBook is having trouble with external monitors connected via Thunderbolt waking up while the laptop is in clamshell mode.  Users in an Apple support forum complain that after a second monitor goes asleep, it fails to properly wake up after the laptop is opened and closed. It can also cause flickering on and off.

This particular issue, however, doesn’t seem to be widespread. It could be related to a recent macOS Monterey update (version 12.01), and as such could affect any Mac running that version. But others chime in to suggest it’s a hardware-centric issue since it’s unclear just how many users have been affected.

Apple’s solution is to disconnect the cable from the external display, then reconnect it. If the display cable doesn't connect to the ports, a Thunderbolt 3 or USB-C adapter is recommended. Apple also recommends connecting the monitor while the laptop is turned off.

If you’re experiencing this issue, it’s a good idea to open a support ticket with Apple, so that any possible bugs can be addressed.
