mac restart issue - circle with line through
After upgrading to High Sierra, my mac pro has been having minor issues, but now it won’t start up at all and during attempts to start up, it sometimes shows a low battery signal even though it’s plugged in. After the latest attempt to start up, the screen showed a circle with a line through it. I read the below support page, but I was wondering whether it’s possible to lose data on my mac after following these steps..?
