    I need to run DVD Studio Pro to open an old project. Unfortunately DVD SP won’t run on anything beyond Sierra and my Mac is now running Mojave.

    I read that I can install Sierra on an external drive but I never really did this before.

    I tried downloading from the App store via this link but I get a error message stating that the requested version of macOS is not available. I think it’s because I’m running Mojave which a newer OS.

    Would someone happen to have a link where I can download macOS Sierra that I can install on an external drive?

    Thank you in advance!

    Depending on how long you have been a Mac user, you can go to the App Store app and click on Purchased and then scroll down the list and most OS’s you have installed in the recent past will be available for download. I see El Capitan, Yosemite, Mavericks, and Lion in my list (I’m on Sierra and have not upgraded because I too have DVD Studio Pro and don’t want it to stop working). Each one has a Download button.
