Some older MacBook Pros have trouble upgrading to Big Sur

A high number of users of the 2013 and 2014 13-inch MacBook Pro have reported that macOS Big Sur update is locking your computers in the installation process.

13-inch and 15-inch MacBook Pro macOS 11 Big Sur has been available to all users since last Thursday.

A thread on the MacRumors forum, as well as a similar thread on the Reddit website and even the Apple community support forum have accumulated several complaints from users to whom their 13-inch MacBook Pros from 2013 and 2014 had their computer frozen, showing an exclusively black screen, throughout the macOS 11 update process. The significant number of accumulated cases suggests that it is a widespread condition.

Those affected report that throughout the update process, the Macs were frozen showing only a black screen. None of the key combinations to restart the computers, as well as to clean the NVRAM, reset the SMC, boot in safe mode or even boot from the Internet are available, which leaves the computers inaccessible after the update attempt.

The models affected as we said correspond to users with 13-inch MacBook Pro from 2013 and 2014, although the extent of the problem is unknown. It is worth mentioning that These are the oldest Mac models that allow upgrade to macOS Big Sur.

Among the most prominent comments of the threads, users who have informed Apple through the support service say they have received different responses, among which are repair requests and as well as the scale of the problem to the team of software engineers, so Apple must already be informed of the error.
