Can you post the exact CPU model here? This will help us to update the sticky CPU compatibility thread.

If you can’t tell us your exact cMP model, for OS installation, only 3 steps.

1) format the target hard drive to HFS+
2) download the installer
3) run the installer

That’s it. Unless your Mac does not support Yosemite natively, but we know nothing about it.

There are a few things going on.
1. Thread title is "mac osx lion cannot install"
2. OP says "but I need just Yosemite"
3. Is OP trying to dual boot for legacy apps?
4. GPU type should be listed. With Quadro 4000 mac, you need 10.6.8 min to boot. OP may have a GPU that needs 10.8.5 or higher.

You have no idea what you said.

1) You don't have a Mac Pro (desktop), but a MacBook Pro (laptop)
2) Your CPU is the Core 2 Duo T9400, I don't know where that 3.2GHz coming from
3) You Mac is not "enough" for High Sierra, at least not natively
4) You Mac is natively supported up to 10.11.6. Apple stop supporting it in the newer OS doesn't mean that they stop your Mac to re-install the supported OS. If it's already in HFS+, please simply go to Appstore, download and re-install the OS. If your Mac has recovery partition, you can finish the process at this (please do some study before you ask if you don't know what is recovery partition).

P.S. You should post this in the OSX forum or MacBook Pro forum, not in the Mac Pro forum.
