I know when Apple went to Tiger and any new computers that came out after the new system was release would not allow the previous OS to be installed. Is this the same case with OS X Leopard and that all new computers bought right now will not take a Tiger install?

I have a few new laptops arriving that if this is the case, they people they are going to will have to wait until I re create completely new images for the laptops with Leopard.

This is going to put us in a Jam as we will put off buying new computers unless 100% needed as we can not add a computer that is running Leopard into a lab that has a OS X Tiger image as one student will be running a different system from everyone else.

If you can not down grade the OS, once I get a new machine I will try removing the HD, put it into a computer that is a close model and install Tiger and fully update the OS then place into the new computer and see if that will work.

It is doubtful that you can do this. Newer OS versions include drivers and support for newer hardware that didn't exist with the previous version. Why is it such a big deal to have machines running Tiger and Leopard together? There should be no issues.

Doofy claims he got Apple to send him Tiger discs for new Leopard hardware he purchased, after he complained about Leopard. It's not something I have heard of Apple doing in the past, so I wouldn't depend on it.

The big reason for this question is that where I support a great number of Mac's and help with the other campus's across the province we all run the same OS to all run from a bas image. The issue is that when we start buying new computers they will all come with Leopard. I already have a few laptops on order for faculty but they will now have Leopard and not the same image as what all the other faculty have as we as the lab.

Also, as we are testing Leopard, we are looking to run Tiger in the next school year until we are all good with a full complete make over of the images with Leopard.

As it stands, if we buy more desktops, we will not be able to keep them running the same images and setup as the rest of the computers without being able to run OS X Tiger.

As for used computers, we have thought about that, but if we want to buy more than just a few, we would be running into the issue of not having either the same models that we have or just hard to find what we need.

I know this is what Apple tends to do but I think it can hurt them. We as a college will need to look at maybe holding off on purchased unless we can come up with a plan to help us on this issues of more than one OS X system in place.

Does your campus have an Apple rep assigned to it? It sounds like there's a large Apple presence there so there should be an Apple rep. If so, he'd be the one to ask.

You must be the fastest typer I know, typing that long response in less than 2 minutes!

In any case, I guess then that this will be a problem for you. When do you expect to finish testing on Leopard? Used machines may be your only alternative if you must have everybody run the same OS (though why can't you have two images: one for existing machines and one for the newer machines with Leopard and then start using the second image once testing is complete?).

Just talked to one of our reps.
Someone from Apple, and from them they said that the MacBook's & MacBook Pro's have been flashed to run only Leopard and newer. As for iMac's & Mac Pro's, not sure if they have been done yet or not.

Though this may leave an open window to buy imacs, it's not an good option to try and stock pile mac's because of this.

On a side note, when this came about with Panther / Tiger it was a lot quicker to just switch to Tiger but at the time, when I was talking with Apple, there was talk within Apple (only rumors) that there may have been a last updated version of Panther 10.4.10 that would have been geared up to run on newer systems to get around this issue.

I wish this were true for the new Tiger / Leopard change over.

Lol... not all that fast

I have two thread on this. One here and the other on the Apple Discussions. Was trying to get the most input as possible on this, so had just finished posting that very paragraph on the Apple Discussion forum and didn't want to re-write the same thing.... so sorta cheated

A user posted this link on the Macnn forum that I have this same topic discussion going as well.

Mac OS X versions (builds) included with Intel-based Macs

The current iMacs will still be able to run Tiger provided your image is 10.4.11, since it came out after the aluminum iMacs were released.

The current Mac Pros will most likely not run Tiger since they came out in January and are an updated architecture.

MacBooks will be Leopard only since they were revamped after Leopard debuted..

MacBook Pros I'd expect to be able to run Tiger still since they haven't had any updates yet.

MacBook Air obviously will not run Tiger.

The Mac mini will run Tiger since it hasn't been updated.
