If you’re experiencing macOS Big Sur problems after installing the new update, this guide should show you how to fix it.
Apple has touted macOS Big Sur as the most revolutionary update to its operating system in years, bringing such large changes that this is no longer a macOS 10.x release (which all versions have been since Mac OS X 10.0 Cheetah back in 2001) but a whole new version: macOS 11.
The release of this major milestone in macOS history coincides with Apple’s newly-launched MacBook Air (M1, 2020), MacBook Pro 13-inch (M1, 2020) and Mac mini (M1, 2020), which all use Apple’s own M1 chip, rather than being powered by Intel hardware.
These new devices come with macOS Big Sur already installed, as Apple has said that the operating system has been built from the ground-up to take advantage of the new hardware.
However, even if you’re running an older Mac or MacBook, you should still be able to use the new operating system. Make sure you check out our how to download and install macOS 11 Big Sur guide for information on safely updating to the new release.
