How to remove extended attributes from all files in a folder on mac

i'm trying to remove the extended attributes from some files (where froms) in a folder on my mac. I could not find a solution for that. Is there a way to remove the attributes from all files in a folder? Kind regards Bijo

Solution 1:

To Remove All Extended Attributes On Many Files

To recursively remove extended attributes on all files in a directory, combine the -c "clear" flag with the -r recursive flag:

xattr -rc /path/to/directory

Open Terminal.app and start typing xattr -rc , include a trailing space, and then then drag the file or folder to the Terminal.app window and it will automatically add the full path with proper escaping.
