Licensing
Select the Licenses menu item from the OmniGraffle menu to see the Licenses dialog. From here you can review and edit your OmniGraffle licenses, which verify that you've actually paid for the software. (Thanks!)
To buy a license:
Click the Buy Licenses button and you will find yourself magically transported to The Omni Group's store on the web. Naturally, this only works if you have a live Internet connection.
To add a new license:
Click the Add License button.
If you have a license key in an e-mail message, copy and paste both the Owner name and the License Key into the appropriate fields. If you can't copy and paste the information, you'll have to type it in; make sure you copy everything exactly as it appears in your license message. Also, double-check that the license you're entering really is a license for OmniGraffle 5, and that it is for the correct edition (Professional or Standard); licenses for other Omni Group products or eariler versions of OmniGraffle won't work.
Use the drop-down menu to select the type of license you would like to use. (Keep reading to learn about license types.)
Click the Save button.
OmniGraffle has two different types of licenses:
Personal: This license is for your personal use, and will only be available on this computer when you are logged on as the user who installed the license. You can install this license on more than one computer, but only for your personal use. You should not use the software on two different computers at the same time with this kind of license. If a personal license is available, the application will always use it.
Computer: You can use this license on this computer, and so can any other user of this computer. However, you should not install this license on more than one computer.
To remove a license:
Select the license you want to remove.
Click the Delete License button.
To move a license from one Mac to another:
First, find the license file on the old computer. OmniGraffle license files are located in the folder Library/Application Support/Omni Group/Software Licenses, where Library is either at the top level of your system disk (for computer licenses), or in your home folder (for personal licenses). The file you are looking for has a name like omnigraffle-123456.omnilicense. Move this file to the new computer.
On the new computer, choose Licenses from the OmniGraffle menu and then click the Add License button.
On the sheet that appears, click the Import License File button.
Locate the license file you want to import and select it.
Click the Open button.
