Hi, I tried to update my Macbook pro 13’ 2019 to Macos Big Sur. After trying to install it, I am having an error. When I turn on my Macbook I see “A software update is required to use this start up disk” and “error occurred installing the update”. I can not use my macbook because of this error. I think it is connected with T2 chip. I gave it to the official apple repair center, they still could not figure it out yet how to solve this problem. Could anyone find the solution of this problem? What did you do?
