We all know that the processes of updating to a new operating system are especially dangerous because one wrong step can turn our phone, tablet and computer into a brick that will only serve as a paperweight. But of course, It is especially disturbing to see that these failures do not come from us but the manufacturer’s. In this case Apple.

And that has happened, that since macOS Bug Sur was released for free for a good number of Macs, The voices of users bitter about the errors produced have not stopped appearing in forums and social networks on older MacBook Pros. Those launched between 2013 and 2014. So now Apple has come to the step explaining a series of steps that we must follow if we find ourselves in the same case.

Black screens

Further, the problem caused by the Big Sur update is not small because after installing the new operating system, many users saw a black screen appear while the computer does nothing else. It stays there, as if it were bricked, which is usually the most scary word for those who modify firmware or operating systems with relative frequency.

macOS Big Sur from Apple.

So if you find yourself in this situation, you must follow the instructions that Apple has published and that go through to the letter:

  • Press and hold the on / off button for 10 seconds– If the Mac is on, it will shut down
  • Disconnect all devices external devices that you have connected to the computer, such as screens, hard drives, SDXC card readers, etc.
  • Turn your Mac back on

If the problem persists, which looks like it will, then you have to resort to tools of greater depth, such as:

  • We restart the NVRAM (or PRAM)

To reset NVRAM (or PRAM), We will have to turn on the computer and, immediately, press the “Option + Command + P + R” keys for about 20 seconds. On models that play a sound on startup, you can release the keys after “the second startup sound.” If you have a MacBook Pro with a T2 (Touch ID) security chip, then you will be able to drop once “the Apple logo appears and disappears a second time.”

If the problem persists, from the company recommend that “affected customers should contact Apple Support for more help with the problem. “So if you have a MacBook Pro from 2013 or 2014, it is almost better to wait for the company to officially announce that this update to Big Sur is completely safe.
