Tiger install on 2011 imac?

[Katgunnderson]

Hi I have a query I'm hoping a mac expert can answer. I have a 2011 imac with Yosemite. However I have some old software I would like to use and wanted to partition the imac and add Tiger on the other partition. I have the Tiger install disks from my old G5, I partitioned the imac but it would not recognise the install disk for Tiger. I think this happened as Tiger is PowerPC and the imac is Intel. My question is, has anyone sucessfully installed Tiger on the imac and if so how? Many thanks in advance.

Are you sure there is not an update to the software? This site can help with that:

Hi, thanks for link but the easiest way would be for me to install Tiger. Is this possible?

Hello and welcome.

Unfortunately, the 2011 iMacs will run a minimum of Mac OS X 10.6.6 Snow Leopard. You cannot install Mac OS X 10.4.x Tiger on them, due to that version of OS X preceding the hardware in your iMac.

Sorry,

According to this:

https://discussions.apple.com/docs/DOC-2541

you would need at least V10.4.4 of Tiger to be able to install it on an Intel-based Mac. However, note that it says "10.4.4 is the beginning for some Intel Macs". Note the "some".

Then there is this:

Oops! I guess Cory you were entering your post while I made mine!

Thank you and Cory for your useful info. It seems I need to get Snow Leopard instead of Tiger. That way this should install on the imac plus my software should hopefully work too. Thanks again.

You're welcome. Are you certain there is not an upgrade for the software you want to run? As it is, you'll need to insure that it is compatible with Snow Leopard.

That's good to know.
