Hey there, shahab92,

Thanks for stopping by the Apple Support Communities. From your post, I understand that you're having trouble charging your MacBook Pro. You have to unplug your USB-C cable and reconnect it, and if you connect a second USB-C device, it stops charging again. I'd be happy to help!

From what you've described, I would recommend resetting the System Management Controller, or SMC. Among some other thing, the SMC handles a few basic power management components. You can get more information on what the SMC does and how to reset it here: How to reset the System Management Controller (SMC) on your Mac - Apple Support .

Additional information about issues charging can be found here: macOS Sierra: If your battery won’t charge .

Have a great day!

Hi MoonJ,

Thanks for your reply.

I tried to upgrade my macOS version from 10.13.3 to 10.13.4 and now it is working fine. I will consider resetting the SMC if it will show me the same behaviour again.

Have a nice day!
