According to Apple’s release notes, the MacOS Big Sur 11.2.2 update can prevent MacBook Pro models of 2019 or higher and MacBook Air models of 2020 or higher from being damaged when they are connected to certain third-party, non compliant usb-c hubs and sleds.
On reddit, there are several reports from Mac users that connecting usb-c hubs and sleds to their devices has made them unusable. The affected MAC appears to be blank and unresponsive soon after connecting to the sled. Many users with problems use hubs and sleds that are not purchased from well-known companies.
Many of the complaints come from M1 Mac users with macbook pro or MacBook Air, but Apple’s release notes show that other models are also affected.
