Install Tiger in a Partition on 2008 MBP running Mountain Lion

You need the computer's original disks or a retail Mac OS X 10.5.4, 10.5.6, or 10.6 DVD to do this. Insert the DVD, restart the computer with the Option key held down, and tab to it.

Older DVDs will not work.

Oh, my is right. I am assuming you need to do this to run your old PowerPC programs?

Your Mountain Lion MBP will not recognize Tiger at all, because your flower power era version was written for the PowerPC. PowerPC apps are dead as disco in Lion and Mountain Lion.

There is a possible workaround though, and that would be to purchase and install Snow Leopard on the partition you created. Snow Leopard is the last OS X version that can run PowerPC programs.

This workaround will work if your used MBP is one built in early 2011 or earlier, and may work if it was built in late 2011. If it was built in 2012, it probably will not.

Purchase Snow Leopard here, before Apple changes its mind. It is still only $19.99.

After you install Snow Leopard on its own bootable volume, you can copy your old PowerPC apps to it and run them. To boot Snow Leopard, use Startup Manager and select the Snow Leopard partition.

If you call Apple and supply your Mac's serial number, you may be able to obtain a set of replacement discs for a nominal fee (about $25). The biggest challenge will be speaking to someone who understands what it is you need.

Great idea...thanks!

And, most importantly, thank you for the info about Snow Leopard. That's fantastic...and only $20!

Just ordered it. My MBP is 2008 so I think it will work.

OK, be sure that when you log in to Apple Support Communities you use the same Apple ID you used when you created your Communities name "SmeeSmee" earlier today.

Having two (or more) Apple IDs will cause headaches. Choose one, stick with it, and make sure your contact information, security questions, and "rescue email address" are kept updated in http://appleid.apple.com. Now would be a good time.

This is more important now than it was in the past, since all your App Store and iTunes purchases are linked to one and only one Apple ID forever.

Ha ha. Okay..but if I could I would!

My username wasn't recognized, my birthdate was wrong, then right, then wrong. It must have taken me 45 minutes to get signed up. And then, I couldn't get back on, but with the software purchase, I was able to confirm that my original login, lcools, was in fact correct,

Again, I hope it's not something on my end....but I will try to get it sorted!

He is not into flower power software, he has the "flower pot" iMac G4 a/k/a the Luxo iMac:

The highest level of Mac OS X that will run on this computer is Mac OS X Leopard 10.5.8. Apple no longer sells Leopard. Copies are available on eBay, but they are pricey.

There are other ways to run your older PowerPC software on your Mt. Lion Mac. What programs are they and what are your needs?

I see - I understood Sally to mean this one:

Ah, I see: hahahahaha 😁

That's an iMac G3!

Rereading the OP, maybe it is MY error! 🙂

I'll take it! Send me an email - my screenname at AOL dot com!

In reality, I need more clarity from you as to what you want to use your iMac G4 for. If you can explain it to me, I will have a solution for you.

If not, I'll take it!
