No, everything worked in this MacBook, there is 1 charging cycle and there are no problems, the problem occurred when updating to macOS 26. There is no support for Apple devices in our country, so I wanted to know if anyone has a similar problem


Re-install the macOS on top of your existing macOS to sort upgrade issues. Easy enough to do.

I bought it a few days ago, but it wasn't from the store. The person from whom I bought it bought it in November 2023 and its warranty has already expired. But the MacBook itself is new, it hasn't been used all this time


+ I checked it through diagnostics, it says that everything is fine. So Apple doesn't see any problem
