ToMacs is a freeware developed to manage your most important data on your Macs: Addresses, Bookmarks, Calendars, Mails, Keychains, and even more thanks to the modules you can download in the preferences panel. All these data are copied throughout your local network in the way you choose: ToMacs will replace a remote Mac's files with a copy from the local Mac or vice versa with just a few clicks. You can also make archives from your files to a USB key or a CD for example, then restore the data later.
Getting started with ToMacs: Download the freeware, install it where you want, enable SSH on your computers and begin to copy your data! Have a look to the help to learn more about the installation if you experience issues and feel free to send me a mail for any support.
