I want to upgrade my wife's machine from PPC to a new Intel iMac which will come with Leopard pre-installed, but for reasons of her user experience I want to move her to the new machine using 10.4 first, then upgrade her to Leopard after a while.

I have a full set of Tiger install disks (the backups from my recent Intel iMac purchase) and a Leopard Update DVD (from ditto).

Is there a smart way to disable/remove Leopard from the new machine I purchase? e.g. do a clean install of Tiger, etc.

Thanks for any thoughts.

No. If you did it any way, it would be unsupported. So don't.

[SidneyP]

What do you mean by unsupported? Warranty invalidation? Something else?

Nope, new machines usually require the OS they have shipped with. There are exceptions, but this is not one of those times. You can make Leopard look more like Tiger, though.

But honestly, just Time Machine for automated backups and more alone is worth sticking with Leopard.

Why wouldn't you be able to put Tiger on the current iMacs, Mac Pros, and Mac minis? They are exactly the same as the were before Leopard came out.

That's (what imitchellg5 says) where I am. I have a two month old Intel iMac which came with Tiger and I subsequently bought a Leopard upgrade DVD but haven't used it yet.

Why can't I buy the exact same machine for my wife (see my reasons in first post), scrub off Leopard, install Tiger. Then, when she's satisfied that we've migrated all her files/apps/etc. from her old G4, and is working OK with it, install the Leopard upgrade and let her then get used to all the new bells/whistles?

I'd think you could just do a clean install. I mean, it's not like this is a new iMac revision, right? It's the exact same hardware with a different OS installed.

Maybe you're underestimating her. I upgraded my wife's macbook to Leopard the weekend it was released, and she's adjusting fine.

I missed that you still have a Tiger DVD. If you have a purely white Intel iMac (not the latest one), it might still happen that it will not install on that new machine. But you can certainly give it a try.

I still don't think it'll be particularly useful. Leopard has been very smooth sailing for me, the differences between the two OS GUI-wise is not very big.

Get an external firewire drive and install tiger on that. Change your boot options to that drive and see how it works. If it does work, either leave it and run it from there or move it to the iMac.

What is so drastically different about Leopard? From an amateur user's point of view, the only differences are that the menu bar dock and windows look a bit different. Everything is in the same place and works the same way.
