    I am looking to download a Sierra installer to create a bootable USB for another mac I have. Is this possible?? I've read online that it's not ( but surely, there's got to be somewhere I can download the file.

    Do I really need to go and find someone with a mac and download it on their computer!!!?? That's beyond ridiculous.

    Using Google to search for "download macOS Sierra" returns this as the first link: which has the link you need to download Sierra from the App Store.

    The point is, is that you CAN'T download it from the App store. It won't let you. There's no way to download it from there.

    Download Disk Drill
    Use Disk Drill to create a bootable installer using the .app macOS Sierra
    If you still cannot download it from the App Store, use @dosdude1 sierra patcher to download the installer instead at Launch the app, hit Tools and download Sierra. If your mac doesn't support Sierra, you can use the patcher.

    You can't download it from there if your computer doesn't support Sierra, no. What computer are you using?

    I don't see where that is. Doesn't look like I can download the Sierra installer through that app.

    Trying to download a older OS (pre-High Sierra) is not allowed because you are on Mojave. I think the reason is when the installer app is downloaded it automatically launches, but Sierra does not recognize APFS volumes and therefore can't launch. The same thing happens on any Mac if a older OS is attempted to download on a Mac that can not run that OS.

    High Sierra can be downloaded on a Mac running Mojave.
