Apple has released a new software update for the Mac, macOS Big Sur 11.2.2, and this update is primarily a bug fix update. This update is designed to protect some model MacBooks from being damaged when they are connected to certain third-party, non-compliant USB-C hubs and docks.
Protecting Your MacBook
This update applies to MacBook Pro models from 2019 onward and MacBook Air models from 2020 onward. It has been released following reports of people’s devices being damaged and not functioning correctly after connecting to these non-compliant docks. The issue has been particularly concerning for users who rely on these hubs for additional connectivity options, such as connecting external monitors, storage devices, and other peripherals.
Some users have reported these issues on Reddit, and this has also happened to M1-based Macs. The hubs used were apparently non-compliant ones, which means they did not adhere to the USB-C standards set by the USB Implementers Forum (USB-IF). This non-compliance can lead to various issues, including power delivery problems, data transfer errors, and, in the worst cases, physical damage to the MacBook’s internal components.
Understanding the Risks
The risks associated with using non-compliant USB-C hubs and docks are not limited to just MacBooks. Any device that relies on USB-C for power and data transfer can potentially be affected. Non-compliant hubs may not regulate power correctly, leading to over-voltage or under-voltage situations that can damage the device’s battery or other internal components. Additionally, poor data transfer quality can result in corrupted files or unstable connections to peripherals.
To mitigate these risks, Apple has taken the proactive step of releasing the macOS Big Sur 11.2.2 update. This software update includes safeguards that prevent the MacBook from being damaged when connected to these non-compliant devices. It is a crucial update for anyone using a MacBook Pro from 2019 onward or a MacBook Air from 2020 onward, as it ensures that their devices remain protected from potential harm.
The new macOS Big Sur 11.2.2 software update is now available to download for supported devices. Users can download the update by going to the Apple menu, selecting “System Preferences,” and then clicking on “Software Update.” It is recommended to install this update as soon as possible to ensure the safety and longevity of your MacBook.
In addition to installing the update, users should also be cautious when purchasing USB-C hubs and docks. It is advisable to buy accessories from reputable manufacturers who adhere to USB-IF standards. Look for certifications and reviews that confirm the product’s compliance with these standards. Investing in high-quality, compliant accessories can save you from potential headaches and costly repairs in the long run.
The macOS Big Sur 11.2.2 update is a vital release for MacBook users, addressing a significant issue related to non-compliant USB-C hubs and docks. By installing this update and being mindful of the accessories you use, you can ensure that your MacBook remains safe and functional. Stay informed and take the necessary precautions to protect your valuable devices.
