Apple - Denied file read access on file I own and have full r/w permissions on
From debugging a different problem (which showed up as deny file-read-data
in the Console, see the other answer), it seems that sandboxd prevents sandboxed applications from reading quarantined data, so I think you'd need to remove the attribute with:
xattr -d com.apple.quarantine /path/to/file
(see for instance https://superuser.com/a/28394/46794). You'd need to prefix the command with sudo
if the file didn't belong to your user, but according to your info it does.
The other user reported that using a non-sandboxed application fixed the problem, and this would confirm that sandboxing is at fault.
An aside: When ls
reports extended attributes with @ next to the permission field, you don't need ls -le file
, but instead ls -l@ file
.
