iSynCal, the iCalendar synchronization tool

The Leopard-compatible version of iSynCal is now available for download!

iSynCal is built to synchronize events and todo from iCal calendars between two or more Mac computers using the standard Apple File Sharing shipped with Mac OSX. Using iSynCal, you no longer need a .Mac account neither to publish your calendars on an external FTP or WebDav server.

You can even use iSynCal to sync your iCal calendars with your iPod or between multiple users on the same Mac.

Since iSynCal reads and synchronizes calendar files based on the open iCalendar standard, used by iCal and by many similar multiplatform applications, it's also possible to use it to sync a Mac user's iCal calendars with those generated, for example, by Mozilla Sunbird or the Calendar extension for Firefox and Thunderbird.

It's even possible to schedule the synchronizations and run them in unattended mode.

iSynCal is localized in English, Italian, French, German, Spanish, Brazillian-Portuguese.

iSynCal  6.0.2  requires Mac OS X 10.4 "Tiger" or 10.5 "Leopard" and iCal 1.5 or later. Anyway, iSynCal may sync the iCal calendars between a Mac running a 10.4 or 10.5 system and another running any system version ranging from 10.2 to 10.5.

iSynCal compatibility with 10.6 Snow Leopard is a bit "random", meaning that I did a lot of testing and it still synchronizes all events/todo at a file level as it did in 10.5 Leopard (as you may have noticed, all calendar-related files are properly copied/synchronized in your ~/Library/Calendars folder) but then iCal acts strangely because some of the calendars show up the new/synchronized items while others not, in a random fashion.

I have further investigated and found no valid reason for this behavior, maybe that Snow Leopard has introduced some "hidden" change to its sync services which messed up iSynCal, so I'm sorry to inform you that I can't fix and update iSynCal to make it fully compatible with Snow Leopard.

Please check the Leopard upgrade info file and remember to read the Known Issues section for important info about a recurring problem experienced by Leopard users.
