Mac OS version conflict

I have a client's Power Mac G5, but don't have the recovery CD's. I tried to install Mac OS 10.3 on it, but it gave me a blank screen with a symbol in the middle and wouldn't go any further. What does it mean? Is it not possible to install another version?

    Accepted Solution

    Generally speaking, you can't install an OS on a Mac that is older than the OS that it shipped with. For instance, if the G5 shipped with OS 10.4, you cannot install 10.3 on it.

    Also, if the install CD you are using was an OEM disk which came with another Mac, it won't work any other Mac except one of the exact same model. (If the CD you are using is a full commercial install CD, then it will work with any Mac that supports that particular version of the OS.)
