Apple unveils how to fix M1-based Mac reinstallation error

There are reports from users that if a new Mac equipped with an Apple Silicon M1 chip is initialized immediately and attempted to reinstall the macOS, an error may occur and virtually become inoperable. In response, Apple has released a supporting document with detailed instructions for recovery.

This symptom is said to occur when attempting to reset and restore an M1-based Mac before updating to Big Sur 11.0.1. Specifically, an error occurred while preparing for the update and the software update could not be customized, so you are asked to try again. After that, it becomes virtually impossible to do anything.

There are two recovery methods suggested by Apple. On another Mac, create a macOS Big Sur bootable installer or use the macOS recovery terminal. Please refer to the official support page for details. Not long ago, there was a report that attempting to update the old MacBook Pro to Big Sur would result in irrecoverable conditions. It will take some time for Big Sur, which started delivery a while ago, to stabilize. Related information can be found here .
