MacBook Pro, OS X El Capitan (10.11.3)
No. If the cable is passing current, it will usually pass enough to meet your MB's needs. Incidentally, you need to update your OS.
I Use Mac 10.11.6 when this happen.
It was just a helpful observation on my part; we are actually on 10.11.6 now. All the same, the cable question is what I tried to address.
how you fix it? I try it on Mac 10.11.6 same thing or I doing something wrong.
I can't imagine a laptop charger causing that problem
