Apple told what you can try to do if macOS Big Sur “broke” MacBook Pro
At the end of last week, MacBook Pro owners of 2013 and 2014 release were alarmed by the news that during the installation of the new micOS Big Sur operating system, laptops may “freeze” on a black screen, and no key combinations will help them to get out of this state. A large number of such cases appeared on several sites at once, including the official Apple technical support community. Therefore, the Cupertino company could not but respond to complaints.
Apple has posted on its website instructions with a sequence of actions in case the above failure occurs during the installation of macOS Big Sur on 13-inch MacBook Pro in late 2013 and mid-2014. You need to do the following:
- Press and hold the Power key on your MacBook Pro for 10 seconds and then release it. If the laptop was on, it will turn off.
- Disconnect all external devices, including external monitors and USB accessories; remove the microSD card if it was inserted into the slot. Then turn on your MacBook Pro.
- If the problem persists, reset the SMC according to the instructions for notebook computers with non-removable batteries.
- If this does not help, reset NVRAM or PRAM.
- If none of the above worked, then Apple recommends contacting support for further assistance.
It is not yet known whether this instruction helped any of the old MacBook Pro 13 ”users affected by the update, because many of them complained that resetting SMC and NVRAM / PRAM is useless. One way or another, Apple has promised to update the recommendations as new information becomes available.
