My Macbook Air 13" (macOS 10.13.6) has a USB problem which triggers a warning notification every five minutes:
Looking in the Console, I see lots of "overcurrent detected" warnings; testing the two USB ports shows that the left one seems dead while the right one works. Visually, the left port is fine; no schmutz that might be causing problems.
Clearly I'm going to have to replace the left USB port (actually the I/O board), but in the meantime is there any way to disable this specific notification? (I really don't need both USB ports; if I could stop the messages I would probably skip fixing the hardware.)
Edit: I wasn't clear: these messages appear even when nothing is plugged into either USB port.
