Apple's latest system software, macOS Big Sur was released on November 12, but several users have reported that some older 13-inch MacBook Pros have been rendered inoperable by the update.

Similar reports have been pouring in on the MacRumors reader forums, as well as on major message boards Reddit and Apple's official support community, suggesting that the problem may be widespread.

The issue is generally that the machine has stopped working with a black screen during the update. Recovery methods such as SMC and NVRAM reset, Safe Mode, and macOS recovery over the Internet are also stated to be inaccessible as keystrokes are not accepted.

Most of these appear to be occurring on the 13-inch MacBook Pros (Late 2013) and (Mid 2014), but it's unclear how large a percentage of users are actually affected. It's also worth noting that both devices are the oldest models supported by Big Sur.

One Reddit user was told by an Apple support representative to send it in for repair (i.e. it was deemed impossible to restore by the user himself). Another on an Apple Support thread also said that the company's engineers had to examine the faulty MacBook Pro, which may have made the company aware of the problem.

In any case, until the cause of the problem is revealed, late 2013 and mid 2014 13-inch MacBook Pro users should hold off on updating to Big Sur.
