Hmm, it’s strange, I didn’t have such an error and my testers didn’t have such an error either, but okay, I’ll figure out what the error is.
What macbook do you have?
Pro mid-2015. Bought it pre-owned and the guy installed some brand of SSD that isn’t capable of updating past Big Sur (11.6), but usually get a more specified error and a “nope” signal over the app if that were the problem.
