Revert to original Mac app icons

I understand what you are saying, my path is the same to what you put there (unless you have to include the Mac OS X part at the start). So unless I had to put the Mac OS X part, my laptop comes with the following message:

There was more but I couldn't fit it in a screenshot.

*It wouldn't say just press it, it would say to backspace it after pressing. I just wrote it wrong, I originally tried it backspacing it. I still have the problem.

Also I can't delete and reinstall the app as it was Safari. I do have chrome so does anybody know how to delete Safari and then reinstall it again?

Somehow, while frantically searching for a solution before this, I found that exact discussion. So for Safari would I type this:

xattr -d -r com.apple.FinderInfo safari

?

Thanks, I think it solved it
