Use calendar and reminders without iCloud
I have Calendar, Reminders and Contacts on my MBP set to sync with iCloud. I have now decided I would prefer to use the apps independently from iCloud, i.e. with the data stored locally on my computer and not sent to iCloud. The trouble is when I deselect each application from iCloud in system preferences, all my events etc disappear from the applications, only reappearing when I tick the box again for iCloud syncronisation. I have even tried backing up to archives before 'unsyncing', then restoring from said archives, but the archives seem to be blank without any events etc.
Any ideas? How can I get the data from iCloud onto my computer and then stop my computer syncing with iCloud?
