mac keep cutting off and blinking folder with question mark

Hello fresh38,

We see you're having an issue with your Mac, and we'd like to help out.

If the Mac is starting up to the question mark, then we'd recommend following the steps on this page: If your Mac starts up to a question mark

As the page notes, the next step would be to reach out to Apple Support directly, if none of the steps have helped. You can use this link to start a support request: Get Support

Cheers.
