Hi,

I have heard that you can, I have a tiger mac with the system requirements for leopard, and I have seen various articles on the web about how to do this, but I don't know if they are legitimate or not. Created by a mac person or a person who was giving bad advice.

I have just received my leopard disk from apple yesterday, and if someone could help with advice or point me in the right direction to where there is legitimate advice that would be greatly appreciated.

Thanks in advance!!!
 
You can't downgrade from Leopard to Tiger -- so the computer you're using has to be one that shipped with Tiger on it. You could partition the hard drive using Disk Utility and install Leopard on one of those partitions.

Look above, he is using a tiger machine. And he doesn't want to "downgrade" if you read the thread title, he wants to install both on the same machine.
 
Well if you want to run Tiger as the main OS, then you can partition the hard drive into two (or more) and install Leopard on one and it should ask which one you want to boot into.

If you want to run Leopard as the main OS, then you can buy and install Parallels and that will let you run two or more OS's at the same time without needing to keep on rebooting. Although I suggest at least 2gb ram per OS.
 
if you partition your drive to have a Mac OS Extended Journaled section - i don't see why you couldn't install Leopard on it... then you can select 'Startup Disk' in Sys Prefs to pick what you want it to start up in (leopard/tiger) and if you changed your mind... it's as simple as holding option on startup

Just wanted to add, that with Parallels or VMware, you can only host Windows based OS'es such as Windows XP or Vista. You cannot host a Mac OS such as Tiger.

Yes, but if you look above, you'll see that I explained how to partition the drive to install both on the same machine. Due to this being a public forum, adding the fact that Tiger can't on a Leopard machine, aka "downgrading", this may save someone in the future looking to accomplish the same thing.

Hi,

You are wrong

VMWare Link

I am sorry, but I don't see it.

Just to make sure that we are on the same sheet of music, I am saying that on a Mac running Leopard (or Tiger) that by using VMware, I can run (host) through virtualization Windows OS'es such as XP and Vista. However, I cannot run (host) through virtualization Tiger within VMware.

If I am incorrect and would you please show me as I would like to do this.
 
Thank you for your help, especially the part about partitioning my drive.

Ok, I am saying, that a Mac running Tiger or Leopard as long as they meet VMWare's Minimum requirements:

Use the recommended versions of the Mac OS X operating system

For Mac OS X 10.4 (Tiger), use version 10.4.11 or higher. For Mac OS X 10.5 (Leopard), use Mac OS X 10.5.2 or higher.

On VMware Fusion, Leopard provides a richer 3D experience than Tiger.

Can run Windows OS'es such as XP or Vista, Mac OS'es, Linux OS'es etc. Not sure what the exact supported OS'es are, but techncially, any should be possible.

Broad Operating System Support

VMware Fusion boasts the most complete OS support, supporting more than 60 operating systems in a virtual machine, including Windows XP, Windows Vista, and even Mac OS X Server.

VMware Fusion was the first virtualization product on the Mac to offer support for 64-bit operating systems, and supports every major 64-bit operating system in a virtual machine.

It shows a Mac desktop running Windows XP, Mac OS X Leo Server and Ubuntu. http://www.vmware.com/files/images/screens_fusion/f2/powertools_serveroses_lg.jpg

Vmware has also several ISOs included with it:

/Library/Application Support/VMware Fusion/isoimages/antivirus.iso
/Library/Application Support/VMware Fusion/isoimages/darwin.iso
/Library/Application Support/VMware Fusion/isoimages/freebsd.iso
/Library/Application Support/VMware Fusion/isoimages/linux.iso
/Library/Application Support/VMware Fusion/isoimages/netware.iso
/Library/Application Support/VMware Fusion/isoimages/solaris.iso
/Library/Application Support/VMware Fusion/isoimages/winPre2k.iso
/Library/Application Support/VMware Fusion/isoimages/windows.iso

I haven't used them, as I already had one I wanted to use.

Hope that helps

Appreciate your detailed response.

The Internet can sometime challenge the message/idea. Probably my fault.

What I believe to be true, is that VMware Fusion cannot run the Mac OS, be it Tiger or Leopard. It can only run Leopard Server -- which is not the regular Mac OS but rather a Server OS.

So if I have an iMac, for example, running Leopard, I cannot use VMware Fusion to run Tiger. VMware Fusion does not support doing that. However, I could run Mac OS Leopard Server.

So I think we are saying the same thing. I mentioned Windows XP and Vista in my original post as examples of Windows software that can be run from within VMware on a Mac running Tiger or Leopard. In fact, currently, I have images for XP, Vista, Windows 2003 Server, Windows 2K and Ubuntu. All work fine for my needs.

If it were possible, I would like to have an image with Tiger and another one with Leopard for some testing. Guess that will have to wait for now.

Using Tiger and Leopard on the same partition has severe disadvantages; for example, Time Machine will get confused every time you use Tiger (so the next time you use Leopard, it will carefully check _all_ files on your hard drive and take forever). If you have space for two partitions, it is easy: Create a second partition, install Leopard on the second partition. To switch, just hold the "option" key while rebooting. Alternative: Buy an external hard drive, install Leopard on the external hard drive. Or use Disk Utility to copy the contents of the internal drive to the external, then install Leopard on the internal.

This may be related to the EULA change that was introduced with Leopard server? AFAIK Leopard server is allowed to run in a virtual machine, whereas single user version is not. Presumably this could be why VMWare don't ship a Leopard single user image.

The Tiger EULA for both single user and server does not allow running in a VM, according to this article.
 
Straight Answer yes...

Complicated answer no...

Apple does not officially allow you to do it... but when you install Leopard... you can partition the disk in Two and have one for Tiger/Anything Else and one for Leopard/Anything Else!!!

Hope that this helps...

This is correct. Technically, it is fine to run it, but as Apple's EULA says its not allowed to run virtually, VMWare have written Fusion to deny the installation.

However, a quick Google search located the process to bypass this which is quite easy, but obviously violates the EULA.

Its user choice really. If I needed to have virtual machines of a non-server Mac OS X client for testing, I would have no problems doing it as I would't be keeping it for any other purpose.

Not saying that you can do it supported, but you can run Tiger as guest OS inside VMware.
It's fun! :cool:

I was looking at the legit side. Understand you can bypass VMware and run Tiger or Leopard.

Well, what if your Mac shipped with Tiger (mine is shipped with Leopard, but I do own Tiger too), and you own VMware and Leopard.
Is running the above illegal? I understand it is not supported, but I don't think I'm doing anything actually illegal....? Technically I will be installing Tiger on a Mac which can be shipped with Tiger etc. Unless somewhere in the EULA it is stated you may not the OS on a Virtual Machine...?
 
sorry to bump this from the dead but its related to this thread.

i have snow leopard installed bootable on an external harddrive, and leopard installed on internal hdd. i want to test SL on external until i am confident enough to do the actual upgrade. is it possible for vmware fusion to boot my external drive?
