Derman Enterprises has released Sync’Em 1.24, an update of the
multi-sync hub for Macs that’s designed to sync Microsoft Exchange,
Google and Apple contact and calendar information.

Sync’Em version 1.24 adds support for recurring and detached calendar
events, support for Google App accounts, multiple usage and
error-handling improvements and now also handles invalid dates
returned from Google and multiple additional kinds of erroneous data
returned from Exchange.

Sync’Em is unique in its ability to multi-sync — sync multiple
configurations, each involving multiple information sources with each
syncing bidirectionally or unidirectionally. Sync’Em has its own
full-featured sync engine that syncs non-Apple sources directly,
enabling it to sync Exchange-to-Exchange, Exchange-to-Google and
Google-to-Google and perform multi-source conflict resolutions in one

Today Sync’Em syncs Exchange, Google/Gmail and/or Address Book
contacts and Exchange and/or iCal basic calendar events. Soon
Sync’Em will be updated to sync Google calendar events and add
multiple Mac-to-Mac syncing that syncs pre-sync’d information, for
maximum efficiency. See
for more information.

Sync’Em can be downloaded via
and requires Mac OS X 10.4 or 10.5. 15-day 2-Mac full-featured Trial
licenses are free and all version 1.x updates are free to registered
