macOS Big Sur: "Black screens" on older MacBooks
MacOS Big Sur has been available since Thursday ready for downloadIf you have an older MacBook Pro, you should wait with the update.
Many Mac users were already experiencing problems with the update to macOS Big Sur on Thursday evening. The high number of requests meant that Apple's servers were overwhelmed. Most people can already enjoy the update with the new features, except for many owners of a MacBook Pro 13" from 2013 or 2014. When updating on these computers, the update often got stuck and a black screen was displayed.
It is unclear what causes this behavior. Possible solutions to the problem do not work or cannot be started due to the "black screen". Since there have been many reports on the topic in Apple's support forum, the manufacturer should already know about it. However, there is no official solution to the problem yet.
