Apple macOS Big Sur 11.0.1 revision update now available for some Macs


Apple macOS Big Sur

After the release of the iOS 14.2 revision yesterday, today, Apple released the macOS 11.0.1 Big Sur revision. This update is already available for some Macs that do not have the macOS 11.0.1 update. As of now, we do not know the exact reason for the release of the macOS Big Sur 11.0.1. Users who have already upgraded to macOS Big Sur will not see this update. However, users of Catalina or earlier macOS can upgrade to the new version.

Apple’s Solution

Currently, Apple has resolved this issue in a new support document that provides instructions on what to do if macOS Big Sur cannot be installed on a MacBook Pro in 2013 or 2014. Here are the steps

  • Press and hold the power button on your Mac for at least 10 seconds, then release it. If your Mac is on, it will shut down.
  • Unplug all external devices from the Mac, including any monitors and USB accessories. Also, remove any cards inserted into the SDXC card slot, then turn on the Mac.
  • If the problem persists, reset the SMC as described for laptops with non-removable batteries.
  • If the problem persists, please reset NVRAM or PRAM.

If these solutions do not work, affected customers should contact Apple’s support department to further help resolve the issue.
