I have a macbook 12'' running sierra that I use occasionally.
The battery died some time ago, showing 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 plug in and connect your power adapter before installing.
Obviously the device is connected to the power source (the battery is dead).
I have already done the SMC reset. Didn't help.
Can I convince the updater to install despite the fact that it thinks I am on battery power?
Can I convince the system to recognize my power connection as an actual power connection?
