How do I stop Calendar from showing my (personal) Google account twice ? Searching on this issue and about the only thing I found was "View, Refresh Calendars", which doesn't help or solve anything. If I right-click, Get Info on each in the left-hand-pane, they're pointing to the same account. Under System Preferences, Accounts, there's only (1) entry for that Google account. I also have my work account (a Google Apps account) and it only shows once. The left-hand pane has: ---------------- On My Mac Home Work Google (my Google account)@gmail.com (my Google account)@gmail.com (1) Birthdays Birthdays (1) Holidays in United States Holidays in United States (1) (my Google Apps account) (my Google Apps account)@companyname.com Holidays in United States Birthdays Other (snip) ---------------- (1) The entries marked are un-checked - no doubt related to the duplicate account I have removed my personal Google account and re-added it more than once trying to start over. How do I make Calendar forget everything so I can start over ?
