A twin-headed USB drive called iTwin Connect, which allows private and public VPN services using a thumb drive dongle, is now available for Mac users running OS X Snow Leopard, Lion or Mountain Lion alongside Windows users. The secure-storage-and-sharing solution using the two-part USB key provides end-to-end encryption for mirroring files, allowing data transfer of files too large for email or too sensitive to transfer using conventional VPN or cloud services. The software for Mac, which was in beta since January, is now final and available.
