[SOLVED] Cannot install Yosemite with Sierra installed...

[waloshin]

Cannot install Yosemite with Unibeast because I have Sierra installed. When I try to open Yosemite I get an error stating that I cannot open Yosemite on a newer version on Mac OS.

Also when I use the Unibeast installer I get an error telling me "
Your selected Mac OS X Installer is incomplete. Please delete all copies of the installer from all mounted volumes and redownload it again from the Mac App Store." even though I just downloaded it from the Appstore.

I need Yosemite to install a driver for a capture card with no support past 10.10.

Update Resolved not sure how but it just worked after starting to re download Yosemite again.

Hardware is working correctly as Kaby Lake CPU and motherboard supports El Capitan and newer. In order to run Yosemite look for older hardware. Z97 is now officially discontinued but should run Mavericks/Yosemite and newer just fine.
