Hello guys, hope you’re doing well. I have a weird question, yesterday I heard apple released a new firmware update for the 140w dc adapter. While doing the firmware update, my Mac lost internet connection. So I was wondering, how can I know if the update successfully installed even if it says it has the latest firmware version in the system log files. Thank you in advance
You can check the installed firmware of the AC adapter by opening the System Information app and navigating to power. In there it should show the firmware version.
Old Firmware: 1040073
New Firmware: 1040084
Verify 140W DC adapter firmware update after internet loss
