My download of macOS Sierra (Developer Preview, see press release) began downloading, appearing in the Launchpad app. But then got interrupted. It failed to restart, so I deleted the icon in Launchpad by holding down Option key and clicking the "X" icon that appears.

Now when I try the download again, the link on the Developer page takes me to the App Store app. There I get page with a Redeem button and an error message saying “This code has already been redeemed.”.

How can I restart the download?

If you have already successfully redeemed your code:

  • Go to the Purchased Tab of the Mac App Store.
  • Click the Download button on the 10.12 Developer Preview listing.

It is the same process as re-downloading anything from the Mac App Store.
