i have an emac using 10.4 and an ibook using 10.5.

i wondered if there is any way i can install 10.5 onto the emac by connecting to the ibook? i tried to install it directly onto the emac but it didn't even show up on my desktop. a friend said it's because the emac is only a cd drive and i need a super drive, this is where i was wondering if i could do it via the network or even firewire.

thank u

emac G4, Mac OS X (10.5.5), ibook G4 OS X 10.5.8 iMac 2.66 intel core 2 duo OS X 10.6.5

    Make sure your eMac is capable of running Leopard.

    This user tip explains when you can use an external Mac's DVD drive to install an operating system:


    If you don't meet those conditions, get an external Firewire DVD drive from http://www.macsales.com/ Otherwise your install may not be that reliable.

    And make sure your eMac is at least 1 Ghz. 800 Mhz and less is not going to work that great. And make sure you are using the retail 10.5 that looks like *

    Note, once you install Leopard on your Mac, you will have forgoe Classic compatibility. Only one eMac model supports dual booting Mac OS 9 and Mac OS X 10.5:


    You will NOT gain Boot Camp compatibility, since your eMac is only a PowerPC.

    If your eMac is only 1 Ghz or less, you can't get USB 2 speeds either.

    Does the dvd for Leopard work on your ibook? If so use Disk Utility (applications/utilities/ on your ibook, or SuperDuper!, (whatever makes you happy) make a image file thats about 8 GB and restore the dvd to the file then follow these instructions.

    Backup everything on your eMac (unless there is nothing important on it).

    Find your Tiger installation disk and boot from it.

    Once it shows up and you have chosen the language go to utilities on the menu bar and chose Disk Utility.

    Partition your drive, make two partitions, and give one of them 8 gigs of space then find a way to restore the image file of the leopard installation disk you made earlier to the partition on your hard drive.

    Once you have finished the restore, IF YOU HAVE A MAC WITH A PROCESSOR SPEED LESS THAN 800MHZ, quit disk utility and proceed to the tiger install and install to the larger partition (when you get to where you chose the drive, uncheck printer drivers and everything else it will install with essentials to make it a short install) IF YOU DONT HAVE A MAC WITH A PROCESSOR SPEED LESS THAN 800MHZ, then quit Disk Utility, go to utilities on the menu bar and choose startup disk. Chose the drive that says Mac OS X, 10.5.1 on (title of drive). let the mac boot and when it shows the chose language part of the installation chose your language and proceed through the installation.

    IF YOU HAVE A MAC WITH A PROCESSOR SPEED LESS THAN 800MHZ, setup Tiger after the welcome video the way you want to and when you reach the desktop, open safari and go to a search engine you like. Look up LeopardAssist then download the app

    Once Safari completes the download there should be a folder saying la233. Open the folder and double-click LeopardAssist and follow these steps
    Click Continue
    Click Continue then click Agree
    Check off Select on Startup (Default) (should be already chosen
    Don't check Verbose Startup
    Click Start

    After the gong it should make after a minute it will let you select the drive you want to boot from. Chose the drive that is labeled Mac OS X 10.5.1.

    After that it should show the usual Apple logo and the spin-wheel, (don't worry, it should take awhile to boot)

    Once the installation screen and when it shows the chose language part of the installation chose your language and proceed through the installation.

    And that's it! If you don't have more than 512 MB of ram then the installation will not continue, so buy some ram. And those who are thinking about booting from a flash drive / external hard drive, then you wont succeed with that, only Intel Macs can do that (i know that ***** but thats a old mac for ya) Enjoy your new OS!!!
