Apple released the highly-anticipated macOS Big Sur last week and many immediately installed the latest version, though some 13-inch MacBook Pro owners say they encountered problems.

Several 13-inch MacBook Pro owners reported experiencing difficulties installing Apple's new macOS Big Sur on their machines. They say the new macOS is having some issues with older MacBooks, such as the 13-inch MacBook Pro models released in 2013 and 2014. Apple moved quickly to resolve the issue and shared some of the ways to fix the installation problem.

   

There are also MacBook users who complained that while they were able to install the new macOS Big Sur, their machines failed to turn on after installing it. Others say that they cannot simply install the update on their machines. If you are among the many 13-inch MacBook Pro users who are unable to install the new macOS Big Sur, you can visit Apple's website and check out the guide that the company shred so you can install the macOS on your machine.

According to Apple, when you install the new macOS Big Sur on some Mac models, such as the 13-inch MacBook Pro models released in 2013 or 2014, the installer might inform you that it cannot install the update on the computer. In some cases, your Mac might just display a blank screen or show a circle with a line going through it, instead of successfully starting when you turn it on.

If you experience macOS Big Sur installation problems or any of these incidents on your 13-inch MacBook Pro, Apple has a guide with some steps that might help resolve the issue. You can first try to press and hold your Mac's power button for at least 10 seconds before releasing it. If the machine is on, it will turn off. Then, unplug any external devices attached to your Mac. These include any displays and USB accessories. If there are any cards inserted in your machine's SDXC card slot, you should remove them too. After doing all these, you can try turning your Mac back on.

If the issue you encountered after installing macOS Big Sur on your 13-inch MacBook Pro still persists, try resetting the SMC as described for Apple notebook computers that have non-removable batteries. If you experience the same issue, try to reset your machine's NVRAM or PRAM this time. After performing all these steps and your problems were not resolved, you should contact Apple Support and have them check the issue.

The Cupertino-based tech giant is yet to issue a statement detailing what is causing the macOS Big Sur installation problem, particularly on 13-inch MacBook Pro models released in 2013 and 2014. Apple also did not say whether it is already working on the problem or has some update to fix what some say is an incompatibility issue. Nevertheless, a disclaimer on the company's website stating they will update the support article soon is giving hope to users that they would have more information about the problem in the coming days.
