Run it from your account first to update the info on the .Mac server. If you haven't run it before you'll first see a message stating that "Before you can synchronise this computer, you need to register it with the .Mac synchronization server." Click on the Register button, enter a name or use the default name, then click Continue. This will produce an empty list of registered machines and 3 options for synching: Safari bookmarks, Address Book contacts and iCal Calendars and To Do items. Check whichever ones you want to sync then, making sure you're connected to the 'net, click the Sync Now button at the top. It'll take a minute or so to upload the data.
Then go to your partners account. From System Prefs go to .Mac and fill in your .Mac account details. Open iSync, go through the setup as above using a different machine name, and click Sync Now. All the data will be downloaded to your partners account and stored in the right places in his Home folder.
If you both use iCal you'll need to call your individual calendars by unique names, so Scot's Work, Scot's Home, Partner's Work, Partner's Home etc. otherwise if you use the same names you'll be overwriting each others calendars every time you sync.
If you haven't got a .Mac account I've just wasted 15 minutes of my life...
Hey thanks for this - I do have a .mac acc so you didnt waste 15 minutes of your life. I will try this next time.
