From the menu bar, choose OmniGraffle ▸ Licenses 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 purchase a license:
To add a new license:
From the menu bar, choose OmniGraffle ▸ Licenses to see the Licenses dialog.
Click Add License.
If you have a license key in an email 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 enter everything exactly as it appears in your license message, including the dashes. Also, double-check that the license you’re entering really is a license for OmniGraffle 6, and that it is for the correct edition (Pro or Standard); licenses for other Omni products or earlier versions of OmniGraffle won’t work.
The Type drop-down menu is grayed out by default, which limits the license type to Personal for the current user account on your Mac. OmniGraffle has two different types of licenses:
If there is more than one user account on your Mac, and you’d like everyone on your Mac to discover the awesomeness that is OmniGraffle, you’ll need to jump through a couple of hoops (thanks to Apple’s mandated app sandboxing for OS X 10.7 and above). To set up a Computer license, follow these steps:
When you click Add License, you’ll notice that the Type drop-down menu is no longer grayed out, and the Computer option is available for selection. Now just enter the Owner and License Key information you received from us, click Save, and you should be set.
To remove a license:
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 such as omnigraffle–123456.omnilicense. Move this file to the new computer.
On the new computer, choose OmniGraffle ▸ Licenses from the menu bar and then click Add License.
On the sheet that appears, click Import License File.
Locate and select the license file that you want to import.
Click Open. If the license file is compatible—meaning, it is for the same version of OmniGraffle—the license will be added to OmniGraffle on your other system.
Again, the thing to remember here is that license keys are version-specific; the license key you have for OmniGraffle 5 is not compatible with OmniGraffle 6 (and vice versa).
