Some users report that the new 16-inch MacBook Pro doesn't always charge when it's completely shut down. Others have problems with external monitors not waking up correctly in clamshell mode.
Some users of the new 16-inch MacBook Pro are reporting hardware issues with MagSafe charging and using external monitors. The first report on Reddit (via “Trillionaire”) included a video showing what happens when the user attempts to charge the device. While the M1 Max MacBook Pro is completely turned off, the MagSafe charging port flashes orange, indicating that it is not charging properly. According to the affected user, Apple Support is investigating the issue and states that "Apple is aware of the issue." Apple Support recommends the following to affected users:
- Charging the MacBook Pro in sleep mode
- Charging the MacBook Pro with the lid open
- Connect the MagSafe cable before shutting down your MacBook Pro.
MacBook Pro 16″: Those affected should contact Apple
Interestingly, according to the thread, the issue doesn't seem to apply to charging via USB-C. Regardless, users have reported issues using external monitors in Apple's support forums. Some issues affect the use of external monitors on all Macs running macOS Monterey. Others report that only the new MacBook Pro exhibits the problems. Typically, in these cases, the external monitors are reported to not reliably "wake up" after the MacBook Pro lid has been opened and closed. If any of you are affected, we recommend opening a ticket with Apple Support. This step not only protects you in case the issue is more serious than originally thought but also provides Apple with additional data to classify and resolve the problem accordingly. (Image: Apple)
