will Leopard run on my iMac G4?
 
I have bought a new iPhone 4. I have an iMac 20inch (pre intel)

My mac is the one with the Screen on the end of a chrome arm. I think its a G4 but not sure

Can I buy and install Leopard (10.5) for my mac so I can use the iphone?

I really don't want to have to buy a new MAC just so I can use my phone!

Thnx

what is the CPU speed of the G4? Click on the Apple and on About this Mac.

it runs at 1.25 ghz Its a PowerPC G4

You can run Leopard on a 867Mhz G4 or higher. The 1.25Ghz will run leopard decently. Might be a bit sluggish in some things but overall it will work fine.

Thanks for that.

The iphone 4.0 requirements are 10.5.8

Will I be able to update that far, on my mac once I have installed Leopard 10.5 ?

Thnx

Yes for sure.

I have just found this on you tube.

YouTube - iMac G4 700MHz RUNNING LEOPARD Mac OS X 10.5.8

It seems I can update to 10.5.8

To install OSX on that 700 Mhz G4, it will refuse to install unless you use Leopard Assist to fool the installer. Like I told you in the other posts, an 867Mhz G4 and up will work with Leopard. Your 1.25Ghz is well above the minimum requirements.

It will work fine.

Thanks for your help. Now I just need to find a copy of Leopard!

And make sure you purchase the black coloured full retail install version only. The silver grey install discs are extremely model specific. They abound on auction sites under a myriad of names including drop in, update, upgrade, full install etc etc.

I'd recommend having a Gig or more of ram if you're planning to run Leopard. Definitely would help with the performance.
