File-syncing service Syncplicity—which recently added invite-only support for Macs—is now open for all users on both platforms. To get started, just head to the Syncplicity signup page, then grab the download. Syncplicity was voted the second most popular file-syncing tool by Lifehacker readers (next to Dropbox), so if you haven't already taken it on a test run, it's worth a try.
