Here are some OS X sharing settings and tips. See also: Operating Systems, Programs, Software.
Mac Pro and MacBook Pro can not send files between each other. Maybe the operating system version needs to be the same. Maybe I need to be signed in via iCloud (in system settings).
Workaround: send files to an Android device and from that device to the other Mac computer.
