Install Leopard on new 27" Intel iMac

We're still a CS3 house, no funds to update all the hardware and software to enable us to upgrade all our users to CS4 ... until late next year. In the meantime, everyone is running Leopard (G4s, G5s, and up).
In the meantime, however, we've purchased several new 27" iMacs, all of which come with Snow Leopard, which we cannot downgrade. I spoke with an Apple tech today, and was told that I could partition the hard drive to install Leopard and Snow Leopard, but I don't know how to do this. Since the new iMac will NOT boot to the Leopard DVD, how do I get Leopard onto the second partition? I've created the partitions and Snow Leopard is running on the smaller partition. Migration Assistant will move the users, apps and files over to the other partition, but not the O.S.
Can I simply just copy the Leopard System Folder from the old QuickSilver (which the iMac is replacing) onto the partition on the iMac which I want to run Leopard? I know this used to work in the olden days ( ... sigh), but I'm doubtful that it's that easy these days.
Thanks for your help.

I understand how the budget is the budget--and that it will only stand so much.

Unfortunately, the tech gave you bad advice. You won't be able to run Leo on your machine.

Unfortunately, no. The good old days are gone. You won't even be able to run Leo on an external drive.

  • Install Leopard with Firewire on G4 imac

    I bought a 1ghz G4 imac with 768mb memory. I am using firewire to install Leopard on it from a Macbook 2008. I create a new partition, I apply GUID. It installs fine. On the Macbook screen it shows up fine. When I disconnect the firewire, drag the hd image of the G4 to the trash on the Macbook screen and turn on the G4, all I get is the flashing folder/face. I hook it up again with firewire to the Macbook and the install shows up. What step did I miss???

    Are you using a retail copy of Leopard?  If it's the one that came with your MacBook, it's machine specific and won't install on your G4. GUID is an intel partition method, you need Mac OS Extended (journaled).

  • Upgrade from 10.4.11 to leopard on White 24"intel iMac?

    I am totally new to MACs and purchased a white Intel iMac for my daughter. It came with a Leopard upgrade or install disc. What is the preferred method to upgrade the system? I have nothing in data at all, its brand new. Should I just do the upgrade from the disc, or an erase and install or archive and install?
    For example, does leopard work better with a fresh install or does it make no difference compared with an upgrade install? Any help appreciated. I am afraid to put leopard on it because it works great now and starts up in a unbelievable 15 seconds from power on to cruise-in the net.

    In your case you must do an Upgrade install as that is the only option for an Upgrade disc. I would do the following:
    First,
    Repairing the Hard Drive and Permissions
    Boot from your Leopard Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Installer menu (Utilities menu for Tiger and Leopard.) After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer.
    Next, continue with Leopard upgrade and follow the instructions provided.
    If DU reports errors it cannot fix, then you will need Disk Warrior (4.0 for Tiger and Leopard) and/or TechTool Pro (4.6.1 for Leopard) to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.

  • Installing Leopard on new hard drive

    Want to replace HD on my dual 1.8 G5.
    How do I go about starting, formatting and installing Leopard on a new blank drive.
    My old drive is backed up on an external using TimeMachine.
    After install I plan to pick and choose what to replace from TimeMachine.
    Thanks for any help.

    First:
    Extended Hard Drive Preparation
    1. Open Disk Utility in your Utilities folder. If you need to reformat your startup volume, then you must boot from your OS X Installer Disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Installer menu (Utilities menu for Tiger or Leopard.)
    2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Note the SMART status of the drive in DU's status area. If it does not say "Verified" then the drive is failing or has failed and will need replacing. SMART info will not be reported on external drives. Otherwise, click on the Partition tab in the DU main window.
    3. Set the number of partitions from the dropdown menu (use 1 partition unless you wish to make more.) Set the format type to Mac OS Extended (Journaled.) Click on the Options button, set the partition scheme to GUID (only required for Intel Macs) then click on the OK button. Click on the Partition button and wait until the volume(s) mount on the Desktop.
    4. Select the volume you just created (this is the sub-entry under the drive entry) from the left side list. Click on the Erase tab in the DU main window.
    5. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, check the button for Zero Data and click on OK to return to the Erase window.
    6. Click on the Erase button. The format process can take up to several hours depending upon the drive size.
    Quit DU and return to the installer. Have your TM backup drive already connected. When installing you will be provided the opportunity to restore an old system from a TM backup. I believe this will appear after completing the Setup Assistant.
    If your old drive is still functional then you can put it in an external enclosure, boot from it and clone it to the new drive after the new drive has been prepped per the above.

  • Installing Leopard (OS 10.5) on iMac G5

    I have tried several times to upgrade the operating system on a G5 iMac but have been unsuccessful. I am using the retail family pack DVD, have removed all peripherals except for keyboard and mouse, but cannot get further than attempting to reboot from the DVD. It starts to load but gets hung up on the spinning little spoke-like wheel thing on the gray background, which spins endlessly until I turn the power off. I have tried using my other iMac as an external drive with a Firewire in the target-host mode but get the same result. Any suggestions are welcomed!

    1. Unless you have a family pack, you shouldn't use the same disc on more than one Mac.
    2. If your Mac has a drive issue with its optical drive, and is a G5, you will need a Firewire DVD drive to load Leopard.
    3. An iMac G5 will not boot from any system specific disc for any other Mac.
    4. 'C' key is not reliable for booting. Try the Startup Manager, if you believe your optical drive should work. That's described here:
    http://support.apple.com/kb/TA27043?viewlocale=en_US
    Only you'd select the Leopard installer disc, and not the hardware test.
    5. If your iMac has 10.4.11, and you are upgrading, be sure to follow these steps to upgrade*:
    http://www.macmaps.com/upgradefaq.html
    6. Target Disk Mode installs only work between similar models and vintage Macs:
    An iMac G5 can't install to an iMac Intel. Only an iMac G5 from August 2005 will install to another iMac G5 from August 2005.
    For more on installing to broken optical drives, see this article:
    http://discussions.apple.com/thread.jspa?threadID=1418365&tstart=0
    7. Before assuming your drive is broken, if it is more than 4 years old, you may need to replace the clock battery. After which point you may need to zap your PRAM:
    http://support.apple.com/kb/HT1379?viewlocale=en_US
    8. Finally be sure to identify your iMac correctly here:

  • Installing Leopard and new internal hard drive at same time, best plan?

    Ok so basically the title explains what I need to do. I am currently travelling in Europe, and returning home to New York on Tuesday night. I have a new hitachi 250gb HD and will have Leopard waiting for me at home when I arrive, and will get right to doing this installation. I am writing on the discussion boards here because I am hoping the users here can give me their opinions on what is the best plan of action to do this whole install?
    So what I was thinking was, I should remove the hard drive that's already inside, put it into an external enclosure. Then, put my new blank 250gb hard drive into the macbook pro, close up the computer, then put the Leopard OSX install disk, and do a completely fresh install of Leopard. Then, after installing (or during installing?) I should run the migration assistant program to get all my files and settings etc. transferred over to the new internal hard drive with Leopard on it, from the old hard drive that will be plugged in from an enclosure as an external drive.
    Will this plan have any problems that I am not aware of? Is there a better process for doing this task? Any advice will be greatly appreciated! I am anxious to get my new hard drive into the computer because my 160gb is filling up, and dying so badly to use the new Leopard!!

    You could also put the new disk in the external enclosure, partition it using disk utility. Then make a clone of your current hard disk to the new external one using the restore feature in disk utility. Boot from the external disk and Install Leopard as an upgrade keeping all your files and setting. check everything is all running how I should and swap drives over. That's another option for you.

  • Missing 50GB's after installing Leopard on new HD-best way to re-install

    I installed Leopard on a G5 tower with 2 new 750 GB's seagate drives. Disk Utility shows a total capacity of 698.6 GB's out of 750 GB's so I am missing 50 GB's. Also first aide hangs up on Verify/repair disk permissions. It looks like I am dealing with an "erase" issue since their must be other files on the new drives that are causing problems, My new thoughts on this are:
    (1)For MacHD 2, in DU click on the "hard Drive(698.6 GB ST3750640AS)/security option-zero out data/erase
    (2) For MacHD 1 (Leopard) insert the installation disk/go to option-erase and install/ok
    Will this work or is there a better way to go about it.
    Thanks for looking at my Post

    Most drives are listed as unformatted size and take advantage of the "1000" kilo which is really 1024.
    Also a system with folders, &c. takes up space with no actual files.
    Your "loss" of less than 10% is normal and expected.
    For example, the "250GB" HD on this MBP as reported by DU says:
    Total Capacity : 232.9 GB (250,059,350,016 Bytes)
    But I have not lost 17GB.
    Since your drive is 3 times the size of mine, I would expect to see a "loss" of 51 GB (3x17) which is exactly what you are reporting.

  • Installing Leopard on New Macbook

    I recently purchased the new Macbooks that came with Snow Leopard, but because they are going in a school enviroment and our software compatibility issues, I need to install leopard on them. I can get the device to boot and show me the retail install cd, but when I click the cd for install it freezes.
    I suspect that the device is booting possibly in 64-bit mode and know I can hold down 32 to get it to boot in to 32-bit mode, but when I do that it wont then let me hold down the option key to access Boot Manager.
    Any ideas or insight would be greatly appreciated...
    Background:
    We recently purchased 25 of the new Macbook for distribution in a school enviroment. When the devices arrived I attempted to do a NetRestore from our Snow Leopard Server with the Leopard image that works on the older macbook models, but when it comes to this model (no firewire edition, suck) it gets a kernal panic error. So I was going to do a manual configuration on a single one of these devices and then use the image utility to create a new image, I could hopefully NetRestore with.

    So,
    Etresoft was correct.
    After some troubleshooting and a call to AppleCare, some discoveries were made that were challenging. I was forced to install Snow Leopard and check the compatibility of our Education software to see if it would run without a problem and it did (thank God).
    The next obsticle was creating the .nbi of the image off the "New Macbook" that no longer supported "Target Disk", with some discussion on the phone with the Apple Rep we both concluded this would only be possible if I were to install Snow Leopard on an external drive and then install the Snow Leopard Server Admin Tools and boot to that. Once that installation was complete, I was able to boot from the external and use the Image tility to get the new image off the device and moved over to our Snow Leopard Server.

  • Can't install logic studio on my Intel iMac

    I have logic pro 7.2 installed on my intel iMac, which now runs maverics. However I now want to install my logic studio upgrade but I get an error saying that power pc applications are no longer supported. How do I get logic studio on my machine which clearly should work as it is built for intel macs when Logic pro 7.2 runs fine!

    The following thread contains the method that uses Pacifist to achieve an installation of older Logic Pros on a Mac with more modern OS X versions when the installer no longer works...

  • Issue Installing Leopard on new internalk drive on older ImacG5

    installed new drive in older ImacG5  I have Leopard install disk...tried to load OSX and install menu does not show target to install...drive is recognized in disk utilities..tried erasing to reformat and erase failed??????

    Drive Partition and Format
    1. Boot from your OS X Installer Disc. After the installer loads select your language and click on the Continue button.  When the menu bar appears select Disk Utility from the Utilities menu.
    2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Note the SMART status of the drive in DU's status area.  If it does not say "Verified" then the drive is failing or has failed and will need replacing.  SMART info will not be reported  on external drives. Otherwise, click on the Partition tab in the DU main window.
    3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Click on the Options button, set the partition scheme to GUID then click on the OK button. Set the format type to Mac OS Extended (Journaled.) Click on the Apply button and wait until the process has completed.
    4. Select the volume you just created (this is the sub-entry under the drive entry) from the left side list. Click on the Erase tab in the DU main window.
    5. Set the format type to Mac OS Extended (Journaled.) Click on the Security button, check the button for Zero Data and click on OK to return to the Erase window.
    6. Click on the Erase button. The format process can take up to several hours depending upon the drive size.
    7. When formatting is complete quit Disk Utility and return to the installer. Install Leopard.
    A possible issue with a new drive is that it came pre-formatted with NTFS or FAT32. A special issue is created by the former that will prevent Disk Utility from partitioning or reformatting the drive. Please check the status reports in Disk Utility for both the drive and the volume on the drive to determine if it is formatted NTFS.

  • Installed Leopard on new drive, now can't uninstall CS3

    I deactivated CS3. Then I installed Leopard on a new drive and it moved over all my stuff from Tiger, including CS3. Of course, due to the idiotic policy that allows you to run 2 copies, but not on the same computer, it won't start. Then when I went to uninstall CS3 using the proper uninstall in Utilities, I got a message that says "System Requirements Error - This software cannot be installed because the file system of the OS volume is not supported". What the heck is that? I have NO way to uninstall CS3? Why the restriction on two copies on one computer anyway? What if your current drive fails unexpectedly? How do you deal with that?

    I have a perfect copy of the boot drive elsewhere on my system. I can boot from it in an emergency. But Adobe tells me that the copy of PS CS3 on that drive is not supposed to work. I called because I had the problem where it dies instantly as soon as you start it. I know the copy was good because I just tested that yesterday, again, during my song and dance to get PS on a non case sensitive drive. PS came up and ran from the spare drive I used as an intermediate Leopard > spare > Leopard. I didn't activate it there but did as soon as I was back on the modified Leopard drive and it's fine. I would say from my previous experience that if I were to boot back to spare and try to start PS, it would now die instantly because it's the second copy and hasn't been activated FROM THAT DRIVE. If I try to activate it I'll get some garbage about too many copies - I don't recall what they said exactly. The gist of it was 2 copies, 2 computers - fine. 2 copies one computer - not OK.
    You say you had 2 copies activated on one computer? How? In my experience, the second copy dies so fast you couldn't get to activation. I'm not doubting you, I'm genuinely curious how it can work. I'm on a Mac Pro, if that's of any import.

  • Can I install leopard on new mac pro intel machine

    This machine came with Snow leopard on it but it is conflicting with a USB 3.0 card I have been trying to install.
    I THINK it is conflicting because I have a similar card on a 2009  Mac Pro intel,
    running Leopard and I have not had one issue since installing IT, many months ago.
    So I thought I would put in a new HD (larger 2TB) and start a fresh install and go down to the Leopard so the USB 3.0 PCI card will work!
    When I do the reboot to instal from the disc, it just sits on a grey screen for 15 min before I gave up.
    I replaced the Leopard disc with a Snow Leopard disc and the boot from disc went as normal.
    So..........

    Like I said, issues.

  • Installing Leopard on new iMac, installation just goes on and on...

    Hi there!
    Just bought a new iMac 24" with OS X 10.4 installed. I ordered the Leopard upgrade and installed it today, and experienced the already documented problem where login password is seemingly accepted but after a few seconds the login window appears again. Recommended solution was to "Archive and Install installation (and select Preserve Users and Network Settings)". I did that, and have now been staring the installation screen for six hours... surely it doesn't take that long to re-install? Installation process started just fine, but after that, no progress. What could I try next? I tried searching the forum and all I found was that one shouldn't interrupt installation process or it would screw things up, so I'm a bit baffled what to do next. Thanks for any thoughts!

  • Re-installing Leopard on new iMac

    Not sure if this is the right place - I have just got a new iMac. I transferred all info (but not applications) from my iBook, and it's just a nightmare - permissions all over the place, loads of keychain problems, etc. I want to start again with a fresh iMac and do it all manually - any advice?

    One last question. My iTunes library was shared between users on my last mac. I have transferred music over but rating etc. haven't come with the library. These seem to be in the individual user accounts for each user - I've tried transferring these files with no success - I understand this is an iTunes question but wondered if you could help - where is that information stored on the mac.
