Dropbox has added two-factor authentication in a pre-release version of its software. The two-factor method requires a password plus a token delivered via another means, such as SMS or a special code-generation iOS app. At Macworld, Dan Moren explains how to use the new option, which reduces the chance of third-party break-ins, as a password alone no longer provides access. But note that AgileBits is recommending that 1Password users who rely on Dropbox for syncing passwords hold off for now. follow link
Edit iCal Event Titles Directly
In the Leopard version of iCal, double-clicking an event shows a summary of the event, and to edit the name (or anything else), you must click the Edit button in the summary pop-up. To bypass the summary and edit pop-ups entirely, Option-double-click the event name. That selects the text for editing, and you can make any changes you want. Click outside the event to save your changes.
