I saw this earlier today and saw everyone said this was impossible. So, as my friend Barney Stinson would say "Challenge Accepted"
- Go into iCal and export all calendars separately.
- Go into Google Calendar (gCal) and create the same calendars from your iCal.
- Import iCal events into the appropriate gCal calendars.
- Delete all calendars from iCal. (You have them saved already so just incase it doesn't work, it won't take long to fix).
- Go into iCal preferences and delete iCloud account.
- While in iCal preferences, add your Google Account.
- Choose the option to synchronize every minute (just so everything stays up to date).
- While in the newly created account, tab over to "Delegation" and select all of your calendars, this way you can see all of them.
- ...You're done. You'll have to set all the colors again though. And because I may have OCD, make sure the iCal and gCal calendar colors match please.
- Test it out! (It may not show up until you hit refresh)
You may be thinking, wait I deleted my iCloud, now my iPhone Calendar won't be up to date.
I fixed that problem too. Im a boss.
Here's what you do on the iPhone:
- Go into Settings --> iCloud and turn off calendar.
- Go into Settings --> Mail, Contacts, Calendar and create a Gmail account and choose the option to sync calendars. (Note: If you are using google to sync your contacts, then you're using and exchange account. You must keep the Exchange account to keep your contacts. The calendar, even though it may say on, won't sync unless you have a Gmail account hooked up.
- Go into your calendar and if the calendars aren't selected, select them.
