Or, maybe you bought DaisyDisk in the Mac App Store? Then you don’t even need a key, it should just work. Please go to the Purchases tab of the Mac App Store and look for DaisyDisk. If it’s there, just click its Install button. (Delete all other copies of DaisyDisk first, to avoid confusion between different versions.)

By the way, we offer free migration from Mac App Store to the more powerful stand-alone version of DaisyDisk.

Sorry, there is a server problem. Please e-mail .

Legacy Versions

Have a Mac running OS X 10.5—10.9? Choose your legacy version of DaisyDisk. They’re no longer updated, but may be really useful for keeping older hardware in better shape. Need a legacy license? Just contact our support team.
