BusyCal or BusyContacts can be installed on up to 5 computers that you own, using the same registration code.

Depending on where you downloaded the apps from (Mac app store or directly from our website), all you need to do is download the apps again on the new computer and add the accounts you had in your old computer (such as iCloud, Google, Exchange, Fruux, Fastmail and so on).

BusyCal - Manual Migration

Re-adding your accounts won't however sync your previously stored preferences though, including any "On My Mac" calendars. If you care about those, you can perform a manual backup and restore.

BusyCal cares about this folder:

~/Library/Containers/com.busymac.busycal3/Data/Library/Application Support/BusyCal

and this file

~/Library/Containers/com.busymac.busycal3/Data/Library/Preferences/com.busymac.busycal3.plist

You can copy them manually from one computer to another, although you must launch BusyCal once on the new computer to set up the container.

On old computer:

IMPORTANT!! In the Finder, select Go > Go to Folder, and paste the following exactly as-is and hit return (You will not find this folder otherwise - they're incorrectly displayed as only "BusyCal" if you look for them manually on macOS 11 onwards such as Monterey, Ventura etc):

~/Library/Containers/com.busymac.busycal3/Data/Library/Application Support

Grab the BusyCal folder

~/Library/Containers/com.busymac.busycal3/Data/Library/Preferences/

Grab the com.busymac.busycal3.plist file

On new computer, launch and set up BusyCal, then quit.

In the Finder, select Go > Go to Folder, and paste the following:

~/Library/Containers/com.busymac.busycal3/Data/Library/Application Support

Copy over the BusyCal folder from your old computer to this location

~/Library/Containers/com.busymac.busycal3/Data/Library/Preferences/
