How can I use Gmail to sync my calendar between Mac OS X and Android?
The approach I took was to sync my phone with the gmail calendar and then sync iCal with google calendar. I don't sync directly between phone and mac.

I can add events on all three now and it will sync between all of them.

edit: I've been asked to post up a screengrab, but it honestly isn't needed. I've seen the guides on setting up CalDav but it's honestly not required, iCal has a really simply method to add an account which makes it extremely simple to do.


Launch iCal
Go to File -> Preferences
Delete any accounts you think you might have set up incorrectly
Add an account with the + button
Leave the account type as Automatic
Enter your google email address
Enter your google password


That is IT! I have a personal and work calendar on google calendar and it brought both in.
