Is there a command that will show which port is being used for charging? From a script, I'd like to check if the power adapter is plugged in on the left, and if so print a message suggesting charging from the right side. I have looked at system_profiler, ioreg, and pmset but the data related to power/charging didn't say which port. Also looking at System Information.app, none of the info indicates which port an adapter is plugged into.
This question is based on this answer which shows that using a left port for charging can cause slower system performance. How to find cause of high kernel_task cpu usage?
