Yes, there is a way to sync from Mac-to-Mac!

You can use the following strategy to sync your contacts and/or calendar events across two or more Macs:

• you'll need either a (free) Google/Gmail account or an Exchange account
• syncing via Exchange provides a few more capabilities than syncing via Google (because there are fewer differences between iCal and Exchange's capabilities that between iCal and Google's capabilities)
• If you don't have an Exchange account, you can get a (relatively inexpensive) hosted Exchange account — see our Exchange Hosting Providers page for information on providers that are known to work with Sync'Em.
• purchase one Sync'Em Contacts or Sync'Em (standard) license for each Mac (depending upon whether you want to sync only contacts and/or calendar events, respectively)
• on one system, setup and sync that Mac's contacts and/or calendar events with the Google or Exchange account
• one-by-one, on the other system(s) setup and sync that Mac's contacts and/or calendar events with the Google or Exchange account

Sync'Em will now keep your contacts and/or calendar events in sync across those systems.

You can easily setup a test scenario — just download Sync'Em and use free Trial licenses (each trial License ID will license 2 Macs). In addition, many of the hosted Exchange providers offer "free for 30 days" trial Exchange accounts.

Notes:

• there's additional information in our Knowledgebase article about syncing multiple Macs
• a Sync'Em Contacts license can later be upgraded to a Sync'Em license, 'though the overall cost is slightly higher
