Not so good
I was an happy user of the old BusyCal (last version was 1.6.4), so (to show my support to the developer) I bought the new BusyCal 2.
DAMN ME!!!!
The new version do not allow you to sync your iphone via ITunes.
You are obly to use iCloud or GoogleCalendar.
But it creates problems (for example the use of Google Calendar sync, inhibits the possibility to attach file to BusyCal events).
So Im obly to uninstall BusyCal 2 and continue to use the old version (1.6.4)
Riccardo PD about
BusyCal 2, v2.0.2
