Hi, I didn't unmount the disk, but how can I do that from the cocoa part of my app. I have the POSIX path to my disk, so how can I unmount using this path? Hi, I'm using "BetterAuthorizationSample" from apple, which installs a privileged helper tool for performing privileged operations. While using this I can obtain a valid file descriptor for reading any disk, I can not get a valid file descriptor for writing to disk (/dev/rdisk1, which is a pen drive). I'm using: fileDesc = open(path, O_RDWR); in the privileged part (helper tool) of my code. This email sent to site_archiver@lists.apple.com
