How can I import my todoist taks in Macbook Calendar?
Please try to add a new calendar and choose to add it from the internet or via iCal/CalDAV, then copy/paste the URL to the iCal feed from Todoist's Settings -> General (at the bottom) and your tasks from Todoist will be displayed in your calendar.
Thank you for your reply.
When I add CalDAV account, it asks to provide the email address and password. What I am supposed to write in there?
If you can refer to any video tutorial would be much appreciated.
That would be if you have a CalDAV account. You should choose iCal from the selection. Though with the OSX calender, with it open, just choose File, New Calender Subscription, then add the URL from the settings page.
