We ran a few tests and this is what we found: most files arrive bit-for-bit identical compared to the files that were sent. But sure enough, MP3 files were downgraded considerably. The 5.12 MB stereo 228 kbps file I bought from Amazon was downgraded to 1.4 MB mono 62.4 kbps on receipt after transfer through Messages.

Why is this happening? We're honestly not sure and I'd rather not speculate. We've reached out to Apple for comment but do not expect a reply.

Nmap ("Network Mapper") is a free and open source (license) utility for network discovery and security auditing. Many systems and network administrators also find it useful for tasks such as network inventory, managing service upgrade schedules, and monitoring host or service uptime. Nmap uses raw IP packets in novel ways to determine what hosts are available on the network, what services (application name and version) those hosts are offering, what operating systems (and OS versions) they are running, what type of packet filters/firewalls are in use, and dozens of other characteristics. It was designed to rapidly scan large networks, but works fine against single hosts. Nmap runs on all major computer operating systems, and official binary packages are available for Linux, Windows, and Mac OS X. In addition to the classic command-line Nmap executable, the Nmap suite includes an advanced GUI and results viewer (Zenmap), a flexible data transfer, redirection, and debugging tool (Ncat), a utility for comparing scan results (Ndiff), and a packet generation and response analysis tool (Nping).
