Also you have to create first the file, it does not exist, so first create it following the path said by Beh and inside the folder create the file

@Beh I manage to discover the calendars from my second iCloud account but then I don’t manage to sync my calendars there, any idea, thanks

I have a question

So far I managed to sync one calendar from one iCloud account, but I would like to sync also a second calendar from a second iCloud account, is this possible?

Thanks
Ricardo
