I have a macbook 12 & # 39; & # 39; who run sierra that i use occasionally.
The battery died some time ago and showed an X in the status bar.
I want to update to a new version of macOS but the installer shows:
Your computer is not connected to a power source.
You must connect and connect the power adapter before installing.
It is clear that the device is connected to the power source (the battery is empty).
I have already reset the SMC. Did not help.
Can I convince the update to install despite the fact that I think I have battery power?
Can I convince the system to recognize my power connection as an actual power connection?
