FirstClassSync for OS X provides synchronization between FirstClass systems and Apple Sync Services. Apple Sync Services in turn provides synchronization between OS X desktops and laptops and products such as iCal, MobileMe, the Mac Address Book, and third party applications and devices. Specifically, FirstClass Sync for OS X makes it possible to synchronize your FirstClass account with Apple iCal, Address Book, and Notes; to synchronize your FirstClass Memos to your iPhone Notes application; and to synchronize your FirstClass account with other applications that have synchronization services clients, for example, Salesforce and Missing Sync. FirstClassSync installs on your Mac and can be configured in your Mac system preferences.
