Apple is on a beta axial rotation in recent months . First itannounceda brief MobileMe Mail genus Beta in May , and this past Wednesday aurora it unveiled aMobileMe Calendar genus Beta . Unlike the Mail beta , however , Apple has made some significant changes under - the - hood , which is causing compatibility issues with at least one third - party app : BusyCal .
BusyMac ’s BusyCal is fundamentally iCal for powerfulness users . It proffer a number of features that go above and beyond iCal , such as integrated calendar communion between multiple Macs , more robust Google Calendar sync , recur to - dos , awkward notes , and more .
Apple ’s MobileMe Calendar beta is incorporating some of these features — calendar sharing being a headliner . But Apple is also switching its calendar technology to CalDAV , a standard Internet data formatting that makes sharing calendars between multiple users well-fixed ( CalDAV is also ramp up into Mac OS X 10.6 Snow Leopard Server ) . Because of this , BusyCal ( and possibly other third - party iCal client and hyperkinetic syndrome - ons ) will need an update to lick properly with the new MobileMe Calendar technology .
In a post on BusyMac’sBusyBlog , the company explains that BusyCal does not yet affirm CalDAV . While there should be no problems with data loss if users swap over to MobileMe ’s Calendar beta , their calendar will be translate - only in BusyCal .
BusyMac says it ’s wreak on an update to plump for CalDAV in BusyCal , and users cansign up to be notified when a genus Beta is readyfor examination . In the meanwhile , BusyMac provides two alternative for BusyCal users : if you desire to help test the MobileMe Calendar genus Beta , you should switch back to using iCal to edit your calendars ( you may rig your default calendar app in BusyCal ’s Advanced preferences pane ) . If you develop into the MobileMe Calendar beta but just ca n’t work without BusyCal ’s features , you could alwaysdowngrade to the pre - beta version of MobileMe Calendar .
For now , BusyMac offers no ETA on when a CalDAV - compatible reading of BusyCal will be available .
