GBCopy for Mac allows you to copy files and folders between two computers connected to the same network, using encryption to ensure that your data is protected. The app comes with a plain interface and rather basic features, but won't disappoint you in terms of functionality.
After unzipping GBCopy for Mac, you must access Terminal to launch the app using the command sh mac_start.sh. The accessible, though somewhat dull, application interface makes it easy for you to back up and compress files on your computer, as well as to copy files between devices on the same network, in which case one device acts as a pusher and the other one as a receiver. During testing, transfers both locally and over the network, completed without any issues. We really appreciated the cross-platform support this app offers, too. Another nice feature is the option to configure your e-mail to send a notification when the synchronization is completed. However, each time we restarted the app, our e-mail settings were lost, so this is something that could definitely use some improvement.
Overall, GBCopy for Mac looks like a stable and handy app. It won't disappoint you if you're looking for a convenient way to back up and copy files over a network. The app would have benefited, though, from some minor improvements and added features, such as a frequently contacted IP address list. Still, it remains a worthwhile download. If you want a good alternative to copying files via FTP, this app is for you.
