Hi there, I am trying to set up a two-way sync between my (many) calendars on iCal and my Google Calendar. I have spent hours on this task, on multiple occasions, and following the instructions on multiple forums and blogs... but to no avail. My largest problem seems to be that iCal will not recognize my Google username/password credentials, even though I am positive I am entering them correctly. I have tried entering them through the iCal program and through the "Mail, Contacts, & Calendars" section of System Preferences. These are the errors I receive, respectively: "Calendar found a CalDAV server but couldn't log in with the user name "firstname.lastname@example.org". Make sure the user name and password you entered are correct, then try again." and "Unable to verify account name or password." Is there anyone here who could suggest a possible cause/solution to this issue? Please note, the username/password credentials I am entering are correct. I even logged out of google and logged back in using the credentials to double-check that they worked. They do. Another bit of information that may help: I tried this with my 3 google accounts. My two accounts that end in "@gmail.com" did not work, but my account that ends in "@maine.edu" (even though it is a domain that functions through google) did work. Hmm... Is there anyone here who knows why google and iCal won't sync?
