Problem with permission on high sierra

I have problem to access my Macintosh HD even I'm admin, I can't change sharing & permissions when I go to Macintosh HD info, I get only message: "The operation can’t be completed because you don’t have the necessary permission." This start happening when I start using High Sierra. If someone have answer to this question please help. Thanks.
