Installing leopard from .dmg file not dvd

i have a mac pro that has 10.4 and would like to install 10.5. The thing is i don't have leopard on DVD it's a .dmg. Is it possible to install leopard onto my 10.4 mac pro without burning a dvd?
thanks
jason

Some things to keep in mind:
1) the only way to install the OS (that I'm aware of) is by using a DVD
2) the DVD you're using MUST belong to that machine OR be a retail copy. The DVD from another computer will NOT work.

  • Need help booting from DMG file without DVD drive

    okay so i have 6 computers with me right now. i need to use one that has a dvd drive to install it on a comp that doesnt via firewire.
    1- macbook with superdrive and os 10.5 (cant even open tiger install because its a new macbook
    2-iBook g4 with DVD drive BUT the firewire port is broken
    3-iBook g3 (one that needs tiger but only has a cd drive)
    4-ibook g3 (without dvd drive)
    5-powerbook g4 with dvd drive and firewire (for some reason will not read the tiger discs i just burned, even though ive already used them on the ibook g4
    6-mac pro with firewire and dvd drive, but the dvd drive is broken.
    so seems to me, every computer i have has a weakness for exactly what i need. what i need to know now is if i can boot the powerbook g4 from a DMG file of tiger install disc 1 and install is to the target ibook through firewire. if you have any suggestions on what i should try with the supplies mentioned above, please inform me. thanks!

    what i need to know now is if i can boot the powerbook g4 from a DMG file of tiger install disc 1 and install is to the target ibook through firewire.
    You can't unless the PowerBook is running Mac OS X Server, in which case the NetInstall feature can be used.

  • Installing apps from dmg file package content windows doesn't gain focus

    When I download a dmg file and double click to mount, after it mounts, the window containing the package contents never gains focus and stays hidden behind the rest of the windows that are open and I have to use Expose to find it. Is this an error or setting I've missed? On my friend's iMac it works fine but not on my MacBook Pro and we both have Snow Leopard.
    Thanks

    Ok the first option didn't have any effect. When I opened the dmg from Chrome it loaded the window in the background.
    Dragging the dmg onto the DiskMounter app worked. The window opened allowing me to drag the App to the Applications folder and was in focus.
    I have a similar issue when I open an archive(zip) file from chrome/safari/firefox it shows the progress of the unarchiving bu then the finder window that would normally come to focus displaying the unarchived folder is hidden behind my other open windows.

  • Can I install Leopard from an external USB DVD drive?

    I am trying to install Leopard onto an older PB G4 whose internal drive is shot. I have an external Pioneer USB 2 drive attached, but when the Leopard Installer prompts me to restart, the installer doesn't kick in and the computer restarts into basic OSX. I've tried to choose the Installer DVD via System Preferences "Start-up Disk" pane, but it doesn't show up. The DVD drive does have its own AC power source.
    Any help would be much appreciated! Thanks!

    Mac OS X will only boot PowerPCs with Firewire, not with USB. That's the reason it doesn't work.

  • How to install leopard from a DMG file instead of DVD

    How to install leopard from a DMG file instead of DVD, When i open this file, click restart, NOTHING happened!!!!!!

    Use Disk Utility to restore the DMG to a blank partition, then use the Startup Disk preferences pane to reboot from that partition. Why not just install from the DVD, though?

  • How to install Leopard from an external DVD reader?

    Hi,
    I've bought Leopard today. unfortunately, it's not yet installed on my PowerBook. As my SuperDrive is dead, I use now an external DVD (Lacie Portable DVD-RW), but it doesn't work. I can read the Leopard install DVD, but when it reboot, it reboot on my current installation.
    I've tried the following during the boot sequence:
    - alt pressed, but I can only see my main HDD
    - c pressed, but I boot on my current installation
    Can you tell me if it is possible to install Leopard from an external DVD, and how can I do that ?
    Thanks in advance.
    Regards,
    Emmanuel Di Pretoro

    Can you tell me if the same problem occur with a FireWire external DVD ?
    It does not occur on your model of Mac.

  • .dmg files not recognised!

    I've a lot of program dmg files on a CD as a backup, and since giving my MBP a clean fresh install of Leopard, these dmg files are no longer recognised. Meaning that when I click on them OSX doesn't know what to do with them! It doesn't recognise any dmg files I download from the internet either. I've tried countless restarts but certainly do not want to install Leopard again! Any advice?

    +"...Since migrating to my new MBP and Leopard (now 10.5.1), I’ve had to keep reassociating DMG files with DiskImageMounter.app – the setting just doesn’t seem to stick..."+
    same here! this is now my fourth installation of leopard; twice with 10,5 and once with 10,5,1 i've installed it, only to 'upgrade' back to tiger after suffering this and a myriad of other teethgrindingly annoying niggles.
    when 10,5,2 came out i thought +'surely they've fixed it by now'+ - only to find this infuriating behaviour still exists. no matter how many times i tell leopard to always open all 'dmg' files with +disc image mounter+, the next time i download one, it either opens in +disc utility+ - if i'm lucky! - or the finder complains it disnae know what a 'dmg' file is - if i'm unlucky!
    you've really got to admire the quality control of a company which releases an OS which - two point upgrades in - still cannae recognise its own in-house file formats.
    oh well, a few more days of this and i then i'll pluck up the energy to 'upgrade' back to leopard again!

  • Installing Leopard from USB flash drive

    Basically i need to install Leopard from a USB flash drive on my Macbook, but i will sum up my issue: (I'm afraid i'm not a computer-"geek", so bear with me when i try to explain the issue :-))
    My macbook hdd recently died on me, so put in a new, clean hdd. I now need to install Leopard on the new hdd from a DMG-file.
    So, i have an 8GB USB flash drive and DMG-file of Leopard.
    I formatted the USB flash drive to NTFS, and copied the 6+GB DMG-file onto the flash drive.
    I tried booting from the flash drive by holding down the option key, but a blank screen shows up with a mouse pointer. There is no Flash drive or install icon to select.
    Can anyone tell me, what i'm doing wrong?

    Hi Dweepe;
    On top of everything else the other posters pointed out, I would suggest that formatting the USB flash drive to NTFS is not doing you any favors either. NTFS is a propriety file system from Microsoft which the Mac can only read with special software install.
    My suggestion is to replace your optical drive. A new one can probably be purchased for much less then the problems you are creating for yourself in your attempts to work around replacing it.

  • Burning DMG File To DVD

    I am trying to burn Adobe CS4 dmg file to DVD as a back up. The size is 6.9GB so I am using a Dual Layered DVD which is at least 8GB. For some reason when I try to burn the dmg to DVD I get a message saying "disk doesn't have enough space. Am I doing something wrong? Here are the steps I took...
    1) Inserted blank DVD
    2) Added DMG file to Disk Utility
    3) Highlighted DMG file within Disk Utility and chose the burn option from the menu
    This method has worked previously with a 6GB dmg file of iLife using the same exact blank Dual Layered DVD. Also, FYI I am running 10.5.5 Thanks for any help. It's greatly appreciated.

    Are you expanding the DMG (you don't want to)? Incidentally, the iLife copy is different than what you are doing. Are you trying to copy the CS4 disk? If so, DU can make an image for you, of the disk. Make certain you save it as a "master", not "encrypted", or any other choice. Then, as you explain, select it, and hit burn.

  • Installing Leopard from which account?

    I am curious whether some people have been installing Leopard from a second or non-adminstrator account.
    If you open a terminal window and enter "id" without the parenthesis, if you are the main or original user, I am pretty sure you should see 501 as your uid.
    Apple starts uids from 501 and up.
    My uids are 501 and 502, for my less-than-full-privileged account.
    I suspect that the install should be done from the main, root, account, the one with full admin privs.
    For those who are having issues with ownership, check your uid as mentioned above.
    I would also check the uid before creating a backup and/or installing Leopard - it might be something of importance.

    I believe the only reason the little "Install Mac OS X" application you double-click on to begin the install process asks for an admin password is for the authorization to set the startup disk to the DVD, which is a requirement imposed by the Startup Disk system preference of the OS it is running under. If you just start up from the DVD directly (using the "C" key or option key methods), you are not asked to authenticate.
    The install itself runs as root & I don't believe any user accounts are created until the setup assistant runs on the first reboot. If you migrate user info from an existing Mac or a connected drive, those UID's & GID's are preserved, otherwise the first account created is an admin user with UID of 501, as it is for any "virgin" install.
    Note also that as long as you have at least one admin account (which can have a UID greater than 501), you can change your 501 user's account type to standard. The password thing seems to have a few causes, all associated with previous accounts created in early versions of the OS like 10.1 or 10.2.

  • How do install Leopard from intel to ppc by Firewire?

    Can anyone tell me how to install Leopard from my intel macbook to my older ppc? When I try to install from firewire it says that the drive is going to GUID and non-bootable. My DVD drive on the PPC isn't good enough for the Leopard DVD. Any suggestions are appreciated.

    I'm not commenting on whether the type of Mac is compatible with the Leopard install.
    I'll offer suggestion for the firewire install. The objective is to take the Leopard DVD and transfer in some way to a firewire drive to be able to boot a PPC Mac and complete a Leopard install to the PPC Mac.
    How? Take a firewire external drive and partition it in two. One for your data and the other (7.2 gigs) max, for the ability to restore the Leopard DVD to that smaller partition. Once restored you'll be able to boot(using system startup control panel) and install Leopard to a PPC Mac.
    The rule to follow is to use APM ie Apple Partition Map to boot PPC Macs. GUID mapping is for intel Macs. You use options within Disk Utility ti select which way to go. You cannot have both on one firewire hard drive. I use two firewire hard drives: one APM and the other GUID.
    How to setup the small partition? Connect firewire drive to your PPC Mac. Open disk utility. Create your two partitions(remember when you do this the drive is formatted and all data is gone, so backup first). Remember to use option and select APM, although on a PPC Mac it should be by default and ditto if on an intel Mac for GUID. Once the partitioning is complete, select Restore and while using the left hand column(just read the instruction in the disk utility window) and assuming you now have the Leopard DVD on the desktop , drag the install OSX section from the left hand column to "source" and then drag the Leopard small partition from the left hand column to "destination." Wait 20 minutes and you are completed. Now you can boot from the firewire drive and install Leopard to a PPC Mac.

  • Can you install leopard from an external usb disc drive?

    I don't know if the disc drive is fast enough for leopard or something. It's taking forever to open the installer, and when I restarted into the installer it just booted back to my desktop. I have an external disc drive I want to try. Can you install leopard from and external disc drive?

    ****, I just tried it and when I restarted it didn't go into the installer. I think my disc drive in my old mac mini might be too slow. It takes forever to recognize the disc and just to double click on it and it up. And when I tried to install it the first time from the internal drive it just booted right into my desktop again.

  • Install Leopard from a .DMG on an external drive?

    Hey guys, last night I got my copy of Leopard, and then the SuperDrive on my 17" 1.33 GHz PowerBook decided to take a dump. It doesn't read anything anymore - not a brand new Leopard disc, a Tiger disc, the System Restore discs, or the Transformers DVD. I used it about two weeks ago to run the Apple Hardware Test from the System Restore discs and it hasn't moved off my desk since, so I have no idea how it died (unless it simply died).
    My brother has a MacBook and I'm planning on getting a triple-interface 1TB drive from LaCie. My question is: can I create a .DMG of the Leopard install disc with my bro's MacBook, move it on to that external drive and install it on my PowerBook from there?

    The guys at MacFixIt have a guide for doing this. It looks like the biggest things are (a) making sure you pick the right partition map for the external (Apple Partition Map for PowerPC, GUID for Intel) to start up from, and making a "CD/DVD Master" image.
    Obviously, installing Leopard isn't going to fix my SuperDrive, but at the moment I only need my SuperDrive to install Leopard (the last time I used it was about two weeks ago to run the Apple Hardware Test and everything checked out, before that I can't remember). I was going to purchase the LaCie Big Disk anyway for Time Machine and storage and to have a bootable Tiger install, so if I can use that to install I can hold off on replacing my SuperDrive. If I can't install it from the external, I can throw my PowerBook into Target Disk Mode and install from my brother's MacBook.

  • Help installing leopard from external fw dvd

    I'm trying to install Leopard on an iMacCore Duo with a broken dvd drive. The hdd has been wiped clean. I've got an external LaCie fw dvd drive hooked up to the iMac. No matter what i do the iMac still gives me the folder with the ?. Holding down the option or C key with the Leopard dvd in the external drive makes no difference. It won't load the dvd. I've also tried using the dvds that came with the iMac. No luck. Not sure how to put OSX on this iMac.
    thx
    lenn

    Have you tried using your installer disc on another Mac just to be sure there isn't a problem with the DVD? I would also contact LaCie tech support. I would be surprised if the device was not bootable. Do you know if the drive is even working? That is are you able to mount the DVD on the Desktop (assuming you can get to the Desktop.)
    You should be able to boot the computer from an external FW hard drive if you have a bootable system on the drive that's compatible with your iMac. You also may be able to install OS X on the iMac from another Mac with a FireWire port by using Target Disk Mode.
    BTW, you aren't trying to use the Leopard installer discs that came with your MBP to install Leopard on your iMac, are you? If so that won't work. The MB{P's discs are machine specific and will not likely boot the older iMac.

  • Is it possible to install leopard from external USB DVD drive?

    Hi all,
    I've read through the various posts on the subject and there doesn�t seem to be a definitive answer on this. I've got a Lacie USB2 DL DVD drive which I'm trying to use to install leopard on an earlier MacBook Pro (core duo 2.0ghz). I've tried the various suggestions (hold c on boot, hold option key on boot, set dvd as startup drive), and so far been unsuccessful. The drive is just not recognized.
    The DVD media is fine(I've got family edition of Leopard), I've successfully installed it on my G5. The Lacie drive recognizes it fine, when I'm in tiger on MBP and insert the disk it is mounted as I would expect. I did try dbl-clicking the install icon as well (in case you were wondering)
    So, does anyone have any other ideas for me to try, or should I go and get a refund on the Lacie drive? The guys in the store (Apple authorized reseller, not Apple Store) assured me it would work, so I don't want to look like a clown if it is possible and I'm just doing it wrong
    Anyway, thanks in advance for any replies.

    Hi,
    Thanks for the reply. Yes the MBP is currently running Tiger, I want to flatten this with a fresh install of Leopard. I can view the install DVD when in Tiger currently.
    I haven't tried what you have suggested, but I have seen various posts suggesting this approach. I've also seen several posts explain how to create a partition on an external firewire Harddrive and this seems to have worked for various people.
    This would however mean that I didn't really need the external Lacie drive at all, as I've got access to my G5s DVD drive over the network. The more I search on this, the more convinced I am the USB drive was a bad idea.
    Once again thank for the response.
