<p>Not to scare anyone, but if you have, or are recently about to purchase the new iLife 11, as soon as you’re done installing it, run Software Update before you even open iPhoto. To do this, click on the black Apple in the upper left corner of your screen, and click “Software Update.” Some folks, including myself, have experienced a loss of photos when updating to the new iPhoto. Thankfully, I was able to recover all my photos, but if you want to avoid a tedious recovery process, do your update!</p>
Also, I was having issues with creating cards in iPhoto ‘11. Apparently, if you have duplicate fonts in your Font Book, you might not get very far with your card or book project. Go into Font Book, and in the menu bar, click on Edit > Show Duplicate Fonts. Then click through each of them and delete them. Once you’re done, your cards in iPhoto will launch just fine.
Furthermore, whenever Apple releases software like this, it’s a good idea to make sure you have a backup in place, in the rare event things go wrong. Shame on you if you’re not backing up your computer.
UPDATE: Apple has released iPhoto 9.1, which restores the ability to create Calendars. Again, a nice feature to have for this upcoming Christmas season. To download the update directly, click here.
