Licensing
Select the Licenses... menu item from the OmniDiskSweeper menu, and you will see the Licenses dialog. From here you can review and edit your OmniDiskSweeper licenses, which verify that you've actually paid for the software. (Thanks!)
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 copy and paste them, you don't have to waste time trying to shove the license key into your short-term memory so you can type it.)
If you can't copy and paste the license, you will have to type it in. (Sorry about that!)
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.
OmniDiskSweeper has three 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. If both a network license and a computer license are available, the application will prefer the computer license. Additionally, this license does not accommodate fast-user switching so multiple users on this computer cannot be running OmniDiskSweeper at the same time.
Network: This license sits on your network and is available to any user on the network. However, only a certain number of users (indicated by the number of "seats") can use the license at one time. OmniDiskSweeper will only use a network license if neither a personal nor a computer license is available.
To remove a license:
Select the license you want to remove.
Click the Delete License button.
To import a license file:
Use this technique to transfer a license file from one computer to another, when you have a valid license but don't recall the details. First, find the license file on the old computer. OmniDiskSweeper 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 OmniDiskSweeper-123456.omnilicense. Move this file to the new computer.
On the new computer, open OmniDiskSweeper's Licenses dialog and 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.
To buy a license:
If you need 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. You can also get to The OmniGroup's store on the web by selecting Buy OmniDiskSweeper... from the OmniDiskSweeper menu.
