Can I safely download MacOS Sierra 10.12 from Apple Support using Microsoft Edge?

I'm looking to install MacOS Sierra 10.12 from Apple Support, though my browser says it can't be downloaded safely, Can I go through with letting it in my computer or should I actually be concerned? I'm using Microsoft Edge as a browser.

Are you trying to download it from Apple directly: https://updates.cdn-apple.com/2019/cert/061-39476-20191023-48f365f4-0015-4c41-9f44-39d3d2aca067/InstallOS.dmg, or the equivalent link from the older installers section of this page: How to download and install macOS - Apple Support? I have no issues or warnings using Firefox. It may be what you need to be concerned about is using Microsoft Edge as your browser?
