Important Note:
Apple no longer provides Mac OS X Yosemite (10.10) through the main App Store interface for modern macOS versions. However, if you need this specific version for an older Mac or legacy software, here is the correct, official method to obtain the Yosemite 10.10.5 DMG or installer.
Final advice: If your Mac can run High Sierra (10.13) or newer, use that instead for better security.
If you have access to another Mac running an older OS, you can download Yosemite using the softwareupdate command:
softwareupdate --list-full-installers

macappstores://itunes.apple.com/app/id915041082?mt=12
This will open the Mac App Store to the Yosemite page.
