On macOS 15.7 and 26.1, scanning Macintosh HD may result in an apparently empty directory labelled as .nofollow.

This is a known macOS issue that can happen in other apps too. Another developer reported this issue in the official Apple developer forum and according to Apple it should be fixed with macOS 26.2 (they didn’t confirm a fix for 15.7 yet): https://developer.apple.com/forums/thread/798402?page=2

If you’re using a non-admin user account, you may be able to work around this issue by using an administrator account.
