Similar Detritus Not Allowed

Daniel Jalkut (tweet):

I’ve noticed folks on Twitter and in developer Slack’s coming up with the same problem. I don’t know if something has changed in the code signing toolchain, or we’re just having an unlucky break, but I thought I’d blog about it because it seems many people may need this advice now.

The error in question is always along these lines:

resource fork, Finder information, or similar detritus not allowed

I’ve long seen this error when there was a com.apple.FinderInfo or com.apple.ResourceFork extended attribute, but apparently it can now occur when there are no xattrs detectable by xattr. It’s a mystery what detritus is attached to the file.
