Hi,

 

I have a iMac PPC  and a iMac intel. Can I install OS 10.4 from a DVD in

the intel iMac running Snow Leopard to the iMac PPC in target disk mode?

    If the PowerPC iMac is in Target Disk mode, no, unless it's the Mac OS X Server Universal Binary; other Mac OS X 10.4 DVDs won't recognize the Intel Mac unless it's designed for the Intel Mac, and if it is, the system won't work on the PowerPC Mac.

    If the Intel Mac is in Target Disk mode, yes, assuming the DVD is at least as new as the PowerPC iMac and noting the point about Intel Mac original DVDs above.

    Niel,

     

    Thanks for the response.

    The model of ths PPC iMac(iSight) is MA064LL/A. The Mac OS X Tiger has two

    DVD's, one is an "install DVD" and the other is a "CPU Drop In DVD" They both

    "include Xcode 2" The intel iMac(Late 2006) is MA590LL, running OS 10.6.8.

    If I use the intel In target disk mode, how do I go about Installing OS 10.4

    on the PPC iMac.

     

    Can you point me in the right direction.

    Insert the install DVD into the Intel Mac and start it up in Target Disk mode.

    Hi Niel,

     

    Did what you told me. Put the install dvd in the intel and brought it up in target mode. Brought up the PPC and selected the install dvd in the start up prefence menu.

     

    Got the same problem when I try to Start up from the install dvd when it is the PPC iMac.Screenshot.jpg

     

    Have no idea what it means. Any help would be appreciated'

    The icon means NO!

     

    Start up the intel mac as before. On the PPC, try booting up the startup manager.

     

    Try holding down the option key then power on. This brings up the startup manager. Click on your DVD. Click on right arrow key.  ( Not sure what the target disk firewire DVD will look like. )

     

    I have not tried this, but read about how this is possible.

    Hi Robert,

     

    I'll give it a try.

     

    The Install DVD in the intel iMac shows up as a hard drive in the PPC iMac starup manager.

    Tried the reboot on the PPC iMac and got the same symbol. It sems the PPC refuses to boot

    from thre OS 10.4 DVD no matter where it is. Can you tell me where you have read about this?

     

    Could it have anything to do with Open Firmware Password protection?

     

    Thanks for the response,

    The Install DVD in the intel iMac shows up as a hard drive in the PPC iMac starup manager.

     

    This is good.  Did you click once on the dvd icon?  Did you click on the arrow key?  What happens next?

     

    You should get a window asking you what language you want to use. next you get the installation panel.

    Tried the reboot on the PPC iMac and got the same symbol. It sems the PPC refuses to boot

    from thre OS 10.4 DVD no matter where it is. Can you tell me where you have read about this?

    Why are you using target disc mode?  If your dvd reader works, there is no need for target disk mode.

     

    Here is what OS came with your machine according to mac tracker.

    Picture 1.png

     

    What the original line means you  is that you need the orginal grey disc or 10.4.3 or greater to install on this machine?  A lot of time machines are shipped with extra drivers which will not be in the standard version of 10.4.2.  You have to wait for a later version of 10.4 to get these drivers.

     

    Where did you get the disc?  You need the black full install dvd's.  Grey dvd are machine specific & are unlikely to work on your machine.

    Could it have anything to do with Open Firmware Password protection?

    I do not think so. The startup mamager would not appear if you had a firmware password.

    Hi Robert,

     

    I bought the iMac PPC used. It came with OS 10.5.8 installed. I wanted to

    installed OS 10.4.11 in order to run Classic. I have the Black OS X Tiger DVD.

     

    I inserted the DVD in the PPC, selected it from the startup manager, but the iMac

    would not boot up, got that silly symbol "NO", never saw it before.

    That is when I tried to put the Tiger DVD in the intel G5 and brought it up in

    Target mode. Went back to the PPC iMac and selected the Tiger DVD from the

    startup manager on the PPC. Restarted and got the same symbol.

     

    Have not been able to select the starup manager during boot of the PPC G5.

    I will try again and let you know.

     

    Thanks again

    What is the OS version on the Tiger DVD? It will be printed on the label near the "install disc" title.

     

    Your Mac shipped with 10.4.2, so any version earlier than that won't boot, and can't be installed.

    Even a 10.4.2 DVD may not work if it's an earlier build than the one shipped.

     

    So your retail Tiger disc needs to be the 10.4.6 one (I don't think there ever was a 10.4.3, .4 or .5 retail)

    The Tiger DVD only shows 10.4 and was created in 2005. Any idea where I might find a Tiger DVD, OS 10.4.6 or layer?

    Alas, only Amazon MP, eBay, and such like now. And the prices are steep (£150 to £250 quoted on UK Amazon - that's around $235 to $400).

     

    One thing you can try (but I can't guarantee they can help) is to call Apple Phone Sales on 1-800-MY-APPLE (1-800-692-7753) and see if they can get you a set of the original grey discs for the Mac. You'll need the serial no. and they do charge for burning the discs, postage and packing, but not a great deal - usually around $16 a disc.

    That pre-supposes that the master for that model is still available of course, but worth a go if you don't have the originals.

    I thought that you got the startup manager to work?

     

    The Install DVD in the intel iMac shows up as a hard drive in the PPC iMac starup manager.

     

    You might take the iMac to an apple store.  Try a very off hour.  They can be rather helpful.  Take you Tiger DVD with you so they know you have a copy of Tiger.

     

    I think you are going to find it troublesome to install classic on this machine too. The only way will be to find someother machine with classic on it & copy the correct folder over.  There may be copyright issues with this approach.

     

    Mac Tracker doesn't list 9.x as being bootable on your machine.

    I've never messed with the firmware password stuff, but I think you get a key icon & you have to enter your firmware password everytime you poweron.  ((( There are ways to reset it. )))

    http://support.apple.com/kb/HT1352

     

    I think if you can find someother iMac PPC machine that will accept your Tiger DVD then upgrade to 10.4.11, then if you move the harddrive to your iMac,  the harddrive will boot your machine.
