Software Update preferences
OmniGraffle can automatically use your internet connection to check for new and updated versions of itself; you can get to these options by choosing Preferences from the OmniGraffle menu, then clicking the Update button.
If the Check for Updates checkbox is selected, you will be notified when there is a new version of OmniGraffle ready for you to enjoy. Click the Check for Updates Now button to look for the newest version manually.
You can select the Include system information checkbox to volunteer some information about your computer's configuration when you check for updates. This information helps Omni make decisions about hardware support in our software. For more details about what kind of information we collect and how we use it, click the Learn More button on the preference pane.
