Users on various forums report problems with their Macs when trying to install Big Sur. The setup then stops and makes the computer unusable, a restart is no longer possible.

The new operating system, including macOS 11 has been available since last week. A large number of MacBook Pro machines of the years 2013 and 2014 be – and here in particular the 13 – inch model, according to a five-page thread in the Apple Support Communities. Common debugging methods seem to fail According to users, the big sur remains -In the meantime the installation shows a black screen – nothing seems to happen after that. Attempts to revive affected computers – for example by resetting, starting safe mode or restoring the Internet – seem to fail, the MacBook Pro remains “bricked”. If Apple is asked what to do, the service is said to have suggested a visit to the Genius Bar in the local Apple Store, reports a user.

Apple itself seems to be informed about the problem in the meantime. One affected person reported that the support team had told him that the bricking had been “escalated” to Apple’s engineering team. What exactly leads to bricking is currently completely unclear – including why older machines of all things are affected. In addition, it cannot yet be said whether only the 13 inch MacBook Pro of these years is subject to a risk of bricking and whether it is possibly a Hardware problem that is revealed by the Big Sur installation.

Make a backup Until Apple has addressed the bug, users of older Macs can only wait with the Big Sur installation; However, not all machines are affected by any means, so that bricking becomes a gamble. You should urgently create a backup before starting the installation of macOS 11.

The update brings In addition to a new surface, various changes under the hood. There are numerous programs that have not yet been or only partially adapted to Big Sur, so there is no rush to install them. However, Apple has apparently only fixed a number of security problems with macOS 11. 0.1, older macOS versions are still waiting for fixes. (bsc)
