    Yesterday I redeemed my code and downloaded the PB Sierra. It took a while so when it was done downloading I turned off my Mac to install it the next morning. In the app store it says it downloaded the files, but it's not clickable. Redeeming the code again it says I already redeemed it. How to install it?

    Did you check to see if it was downloaded into your applications folder? It shows up in your launchpad as well, take a peek there.

    Checked. It's indeed in the applications folder! Thanks so much!

    Rather than start a new thread on this, I thought I'd add my experience here although it seems the OP problem is resolved. I found this thread doing my own troubleshooting so maybe someone will similarly wander upon it.

    I downloaded the Public Beta and on launch got the message:

    "This copy of the Install macOS Sierra Public Beta application is damaged, and can't be used to install macOS."

    I downloaded it twice more to the same irritation. Grrr

    In the end I used Disk Maker X to create a bootable install drive (it hasn't been updated for Sierra support and it did throw up some error messages while running, but it did still succeed in creating a bootable drive). I installed the OS successfully from there.

    Still no clearer why the download said it was screwed. Only thing I can think of is that my internal drive is fried so perhaps the installer failed when encountering something it wasnt expecting? (speculation)
