iCal Not Supporting Delegation to My Gmail Accounts (And Even iCloud)

Hello!

I don't know why iCal does not support delegation to my Gmail Accounts anymore. And even my iCloud Account. The following picture shows it. The sidebar doesn't show the accounts' emails. I'll explain more about iCloud later.

Focusing on Gmail, it all started with me attempting to add another even in Google Calendar. After I did add an event, I expected that iCal would sync with Google Calendar like always. I went and checked out preferences and it said that the iCal couldn't support delegation on those accounts. Maybe that was the reason why. So the first thing I tried to do is to refresh the calendars. Nothing happened. And then I deleted the accounts from iCal and Re-Added them. Nothing happened also. The sync didn't work still.

Now on to iCloud, you've seen the first photo that iCal was able to show iCloud's Calendars on the sidebar. The thing is, iCal also mentioned that it can't support delegation on this account.

I don't really use iCloud's calendar, but I still want it to work because it's where I back up my past calendars that aren't from Google.

Please help. Thank you!
