Can't mount shared disks on a Apple Airport Extreme [AFP Mount]

[stevev1]

Mac OS Sierra is out [Roon B161 supports it]

If you’re willing to execute a command after every boot, there’s simpler way but it till requires you to use Terminal. Open Terminal and run: “sudo chmod a+rwxt /Volumes”; it will prompt you for your password. Once executed, Roon should work with SMB disks, you might have to restart Roon though.

This will fix it until the update.
