Looks like no one’s replied in a while. To start the conversation again, simply ask a new question.

I have a trouble with USB. When I connect my iPhone for charge ,immediately cut power of mac. There is no problem with flash memory. Can read and load program. This problem appeared suddenly and looked for some solution in apple support communities.

Do you have some suggestions for solution about power cut of Mac.

Thank you

MacBook Pro 13″, macOS 10.15

Greetings aydin210,


When you attempt to charge your iPhone, make sure that your Mac is also connected to a power adapter.
