Running Snow Leopard & Tiger on same Mac unit

How can I install both Tiger AND Snow Leopard on the same Intel Mac, and have the choice to choose either OS at start up to work with?

You would have to partition your hard drive into at least 2 partitions, then install Tiger on one partition and Snow Leopard on the other. When you boot you will have to hold down the Option key to have your Mac allow you to choose which partition to boot from.
Alternatively, you could install the second OS version on an external FW drive. But the drive would have to be connected & powered on before you start up your Mac in order to be able to choose it for startup.
Note: You should not, and in most cases cannot, install an earlier version of OS X than what came with your Mac. So, if your Intel Mac came with Leopard or Snow Leopard on it, you probably won't be able to install Tiger on it.
Why do you want to do this?

  • Tiger and Snow Leopard on the same Mac

    I need to use some Apps that are Tiger only and so I thought to install Tiger on my MBP using a virtualization software. What would you recommend? VMWare Fusion? Parallels? Any other?
    Thank you!

    Is there a way to RUN TIGER on my MBP? Anyone?
    NO. if you want to run tiger you'll need an older mac. there is NO way to run it on your MBP.

  • How to install and boot both Leopard and Snow leopard in the same Mac?

    I've installed 10.6 (SL) on my MacBook. After I installed SL, I found that a couple of softwares that were working in 10.5 don't work anymore and the providers don't have any update nor any support to the date. Then I decided to make a disk partition: the main with 10.6 and a small one with 10.5 to use with these specific softwares. (the idea is to switch from 10.6 to 10.5 and vice versa)
    I've searched in many Mac discussion forums and manuals for instructions to do that without success.
    I'm novice with these stuffs, so, somebody could help me with the right steps to do that? (in this moment I've already partitioned the HD: 220 Gb and 25 Gb)
    thanks in advance

    You just insert your install disk and when it asks where you want to install the OS, you choose the partition you want it on.
    If there is something about this which is still not clear, just post again.

  • Mac pro shipped with OS 10.73 able to run snow leopard

    I'm trying to salvage my old power PC applications and am hoping I will be able to run them if I load Snow Leopard.  My mac pro is a 2 x 2.4 GHZ quad core xeon mac with 10.7.3 shipped loaded.  Is there a way to run OSX 10,5.8?.  will booting in 32 bit mode help with the old apps?

    How To Run Snow Leopard On A New Mac
    This does not apply to new Mac Minis or MacBook Airs. When newer models are introduced that also require Lion for hardware support, the techniques described below will no longer work with the possible exception of using Parallels 7.
    What has to be done:
    Create a new partition on the hard drive.
    Get a clone of a 10.6.8 Snow Leopard system. Put the cloned Snow Leopard system onto the new partition.
    Step One: Create a new partition on the hard drive
    To resize the drive and create a new partition do the following:
    1.           Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
              After the main menu appears select Disk Utility and click on the Continue button. Select the hard drive's main entry then click on the Partition tab in the DU main window.
    2.           You should see the graphical sizing window showing the existing partitions. A portion may appear as a blue rectangle representing the used space on a partition.
    3.           In the lower right corner of the sizing rectangle for each partition is a resizing gadget. Select it with the mouse and move the bottom of the rectangle upwards until you have reduced the existing partition enough to create the desired new volume's size. The space below the resized partition will appear gray. Click on the Apply button and wait until the process has completed.  (Note: You can only make a partition smaller in order to create new free space.)
    4.           Click on the [+] button below the sizing window to add a new partition in the gray space you freed up. Give the new volume a name, if you wish, then click on the Apply button. Wait until the process has completed.
    You should now have a new volume on the drive.
    It would be wise to have a backup of your current system as resizing is not necessarily free of risk for data loss.  Your drive must have sufficient contiguous free space for this process to work.
    Step Two: Obtain a clone of a Snow Leopard system:
    You will need access to a Mac already running Snow Leopard. You will need a 16 GB USB flash drive or an external hard drive to which you can clone the Snow Leopard system from the Mac that has Snow Leopard installed. Alternatives are:
    Option One:
    Install a new Snow Leopard system onto a USB flash drive. Boot the Mac used for installing with the USB flash drive. Update the flash drive system to 10.6.8 using the Mac OS X 10.6.8 Update Combo v1.1 to update Snow Leopard. Verify that you can boot the Mac with the USB flash drive.
    Take the USB flash drive to your new Mac and try booting from it. If it works then clone the system from the flash drive to the newly made partition:
              Clone using Restore Option of Disk Utility
    Open Disk Utility from the Utilities folder.
    Select the destination volume from the left side list.
    Click on the Restore tab in the DU main window.
    Check the box labeled Erase destination.
    Select the destination volume from the left side list and drag it to the Destination entry field.
    Select the source volume from the left side list and drag it to the Source entry field.
    Double-check you got it right, then click on the Restore button.
              Destination means the new partition on the internal drive. Source means the USB flash drive.
    Option Two:
    If you have a large enough external drive you can erase and use, then it would be easier to just clone the entire Snow Leopard system from the source Mac computer to the external drive.
              Clone using Restore Option of Disk Utility
    Open Disk Utility from the Utilities folder.
    Select the destination volume from the left side list.
    Click on the Restore tab in the DU main window.
    Check the box labeled Erase destination.
    Select the destination volume from the left side list and drag it to the Destination entry field.
    Select the source volume from the left side list and drag it to the Source entry field.
    Double-check you got it right, then click on the Restore button.
              Destination means the external drive. Source means the Snow Leopard Mac's internal drive.
    After cloning verify that it will boot the source Mac. If so then take the external drive to your new Mac boot with it. If all is well then restore the clone to the new partition on your new Mac:
              Restore the clone using Disk Utility
    Open Disk Utility from the Utilities folder.
    Select the destination volume from the left side list.
    Click on the Restore tab in the DU main window.
    Check the box labeled Erase destination.
    Select the destination volume from the left side list and drag it to the Destination entry field.
    Select the source volume from the left side list and drag it to the Source entry field.
    Double-check you got it right, then click on the Restore button.
              Destination means the new partition on the internal drive. Source means the external drive.
    If the above seems too daunting then you might consider running Snow Leopard inside an emulator such as Parallels 7. You are permitted to install a single copy of Snow Leopard inside a virtual machine. You will need to first purchase a copy of Parallels 7 and install it on your new Mac. Create a new virtual machine configured for Mac OS X. You may then install Snow Leopard in the virtual machine then download Mac OS X 10.6.8 Update Combo v1.1 and update to 10.6.8. Be sure to include Rosetta in your initial Snow Leopard installation. Rosetta is not installed by default rather it's an optional install.

  • Snow Leopard on late 2012 Mac Mini

    I need to run Snow Leopard on late 2012 Mac Mini in order to use PPC applications.
    How can I install Snow Leopard on out-of-the-box Mac Mini?
    Please advise.

    There is no "perfect" solution to your problem.
    There is a thread on this forum about how to get the 2011 Mac Mini to run Snow Leopard with amazing work by Newfoundglory:
    https://discussions.apple.com/message/17829389#17829389
    Installation of Snow Leopard Server is actively supported by all of the virtualization companies.  While it sold originally for $499 from Apple; you can now find it for about $125 or less on eBay.
    Installation of Snow Leopard client is not actively supported by any of the virtualization companies (with the sole exception of v4.1 of VMWare Fusion, which is now hard to find for obvious reasons and then can NOT be upgraded or this capability is lost). 
    These practices by these companies are a part of the common Urban Myth that the Snow Leopard EULA prohibits the virtualization of Snow Leopard in Lion or Mountain Lion. 
    I have posted detailed instructions on how to install Snow Leopard into Parallels at this link:
    http://forums.macrumors.com/showthread.php?t=1365439
    While it is not as easy to install as Snow Leopard Server, it is certainly doable and many successes are cited in that thread.  If you decide to go that route. let me know over on MacRumors and I am happy to help you out!
    Good luck!

    IS THE SITUATION HOPELESS
    I used Target mode to transfer files to a new i7  iMac running Snow Leopard 10.6.8 from an older Dual core Intel machine (EMC 2105) also on 10.6.8. but originally Tiger 10.4. The operation was successful and I ejected the disk icon from the new machine and powered down the old machine. When this was restarted the next day there was a grey screen with flashing Mac symbol alternating with a 'no entry' sign and occasionally a question mark.Keyboard and mouse were unusable so k inserted the original instal disc (No.1 for 10.4. with installer 1.0.4) which came with the machine in 2006 in an attempt to boot from this. The ensuing window said this was not possible and now it cannot be ejected.I have tried everything ! It offers Disk Utility and other options like Terminal but that doesn't work either.I 'repaired disk' and that was pronounced o.k. None of the various keystrokes at start up will work, and the computer will only offer the installer disc continually.The only option would seem to be is to erase the hard drive completely from the disc in the machine.I don't want to do this as there is still material which I need to recover. I think the drive has in some way been corrupted by using it in target mode, and I don't know if there are any other options to try.
              Please tell me how to get this disc to eject !

    Have you seen this type of problem before? I think it could be a serious issue for anyone in a similar position.
    No; but then, I've not had occasion to use TDM. I've been using firerwire drives for over 10 years, both FW400 and FW800, with no issues except a bit of instability using a B&W G3 machine.
    TDM should be safe. Using cautious, manual copying of files from the Target machine to the Host machine should not result in unexpected loss of files or damage to the Target drive's directories. It should behave exactly the same as if it were an external (to the Host) firewire drive.
    •  I don't suppose there is anything I can do to 'put back' lost items from a separate Time Machine drive which has an up to date backup on it.
    There is probably a way to do that - seems to me that's one of the reasons for a Time Machine volume.
    On the other hand, if the Time Machine volume is rigidly linked to the now-absent OS on the original drive, there may be no way to effectively access the files in the TM archive.
    I know that using a cloned drive would work well in this instance.
    I have no experience with Time Machine, so perhaps someone who has will chime in with suggestions.
    With the machine in TDM with the other machine, have you tried running Disk Utility to see if you can effect repairs to the drive?

  • Cannot access safe boot for Mac Air running Snow Leopard any suggestion please?

    Mac Air - Mid 2011 (79gig free space). Running Snow Leopard 10.6 + all updates installed to-date. Last update was iTunes 98m file which was installed 4 days ago.
    Unit has progressively slowed up, starting with intermittent freezing of cursor, which appears to have started not long after connecting iPhone 5 running current iOS.
    Have accessed Safe Boot and ran drive utility check, all ok.
    Received error message after drive check stating, "(AppleUsbEthernetHost.text) incorrectly installed".
    Have subsequently tried accessing Safe Boot again to try and reset permissions, but can not access as unit constantly freezes at Login page.
    Have followed Apple support recommendations to access Safe Boot, but to no avail.
    Have seen forum references to the above error relating to iOS mobile devices causing problems with earlier versions of iTunes updates. 
    Any suggestions as to how to proceed from here would be appreciated ?

    I suggest you backup your files, if possible, then do the following:
    Clean Install of Snow Leopard
    Be sure to make a backup first because the following procedure will erase
    the drive and everything on it.
         1. Boot the computer using the Snow Leopard Installer Disc or the Disc 1 that came
             with your computer.  Insert the disc into the optical drive and restart the computer.
             After the chime press and hold down the  "C" key.  Release the key when you see
             a small spinning gear appear below the dark gray Apple logo.
         2. 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.
             After DU loads select the hard drive entry from the left side list (mfgr.'s ID and drive
             size.)  Click on the Partition tab in the DU main window.  Set the number of
             partitions to one (1) from the Partitions drop down menu, click on Options button
             and select GUID, click on OK, then set the format type to MacOS Extended
             (Journaled, if supported), then click on the Apply button.
         3. When the formatting has completed quit DU and return to the installer.  Proceed
             with the OS X installation and follow the directions included with the installer.
         4. When the installation has completed your computer will Restart into the Setup
             Assistant. Be sure you configure your initial admin account with the exact same
             username and password that you used on your old drive. After you finish Setup
             Assistant will complete the installation after which you will be running a fresh
             install of OS X.  You can now begin the update process by opening Software
             Update and installing all recommended updates to bring your installation current.
    Download and install Mac OS X 10.6.8 Update Combo v1.1.
    Reinstall your third-party software from the original media. Restore your data from the backup.

  • Updating from Tiger to Snow Leopard without buying the Mac Box Set

    Is it possible to update from Tiger to Snow Leopard without buying the Mac Box Set? My sister already has iLife 09 so I could borrow it and simply buy Snow Leopard. Is that possible or would it still violate the licensing agreement?

    R C-R:

    Purchased a used macbook pro with Mountain Lion. My old Mac runs Snow Leopard is backed up to Time machine. How do I register the operating system to me and how do I use Time Machine to move my files to the new used computer?

    If you look at the User Tips tab, you will find a write up on just this subject:
    https://discussions.apple.com/docs/DOC-4053
    The subject of buying/selling a Mac is quite complicated.  Here is a guide to the steps involved. It is from the Seller's point of view, but easily read the other way too:
    SELLING A MAC A
    Internet Recovery, and Transferability of OS & iLife Apps
    Selling an Old Mac:
    • When selling an old Mac, the only OS that is legally transferable is the one that came preinstalled when the Mac was new. Selling a Mac with an upgraded OS isn't doing the new owner any favors. Attempting to do so will only result in headaches since the upgraded OS can't be registered by the new owner. If a clean install becomes necessary, they won't be able to do so and will be forced to install the original OS via Internet Recovery. Best to simply erase the drive and revert back to the original OS prior to selling any Mac.
    • Additionally, upgrading the OS on a Mac you intend to sell means that you are leaving personally identifiable information on the Mac since the only way to upgrade the OS involves using your own AppleID to download the upgrade from the App Store. So there will be traces of your info and user account left behind. Again, best to erase the drive and revert to the original OS via Internet Recovery.
    Internet Recovery:
    • In the event that the OS has been upgraded to a newer version (i.e. Lion to Mountain Lion), Internet Recovery will offer the version of the OS that originally came with the Mac. So while booting to the Recovery Disk will show Mountain Lion as available for reinstall since that is the current version running, Internet Recovery, on the other hand, will only show Lion available since that was the OS shipped with that particular Mac.
    • Though the Mac came with a particular version of Mac OS X, it appears that, when Internet Recovery is invoked, the most recent update of that version may be applied. (i.e. if the Mac originally came with 10.7.3, Internet Recovery may install a more recent update like 10.7.5)
    iLife Apps:
    • When the App Store is launched for the first time it will report that the iLife apps are available for the user to Accept under the Purchases section. The user will be required to enter their AppleID during the Acceptance process. From that point on the iLife apps will be tied to the AppleID used to Accept them. The user will be allowed to download the apps to other Macs they own if they wish using the same AppleID used to Accept them.
    • Once Accepted on the new Mac, the iLife apps can not be transferred to any future owner when the Mac is sold. Attempting to use an AppleID after the apps have already been accepted using a different AppleID will result in the App Store reporting "These apps were already assigned to another Apple ID".
    • It appears, however, that the iLife Apps do not automatically go to the first owner of the Mac. It's quite possible that the original owner, either by choice or neglect, never Accepted the iLife apps in the App Store. As a result, a future owner of the Mac may be able to successfully Accept the apps and retain them for themselves using their own AppleID. Bottom Line: Whoever Accepts the iLife apps first gets to keep them.
    SELLING A MAC B
    Follow these instructions step by step to prepare a Mac for sale:
    Step One - Back up your data:
    A. If you have any Virtual PCs shut them down. They cannot be in their "fast saved" state. They must be shut down from inside Windows.
    B. Clone to an external drive using using Carbon Copy Cloner.
    1. Open Carbon Copy Cloner.
    2. Select the Source volume from the Select a source drop down menu on the left side.
    3. Select the Destination volume from the Select a destination drop down menu on the right
    side.
    4. Click on the Clone button. If you are prompted about creating a clone of the Recovery HD be
    sure to opt for that.
    Destination means a freshly erased external backup drive. Source means the internal
    startup drive. 
    Step Two - Prepare the machine for the new buyer:
    1. De-authorize the computer in iTunes! De-authorize both iTunes and Audible accounts.
    2, Remove any Open Firmware passwords or Firmware passwords.
    3. Turn the brightness full up and volume nearly so.
    4. Turn off File Vault, if enabled.
    5. Disable iCloud, if enabled: See.What to do with iCloud before selling your computer
    Step Three - Install a fresh OS:
    A. Snow Leopard and earlier versions of OS X
    1. Insert the original OS X install CD/DVD that came with your computer.
    2. Restart the computer while holding down the C key to boot from the CD/DVD.
    3. Select Disk Utility from the Utilities menu; repartition and reformat the internal hard drive.
    Optionally, click on the Security button and set the Zero Data option to one-pass.
    4. Install OS X.
    5. Upon completion DO NOT restart the computer.
    6. Shutdown the computer.
    B. Lion and Mountain Lion (if pre-installed on the computer at purchase*)
    Note: You will need an active Internet connection. I suggest using Ethernet if possible because
    it is three times faster than wireless.
    1. Restart the computer while holding down the COMMAND and R keys until the Mac OS X
    Utilities window appears.
    2. Select Disk Utility from the Mac OS X Utilities window and click on the Continue button. 
    3. After DU loads select your startup volume (usually Macintosh HD) from the left side list. Click
    on the Erase tab in the DU main window.
    4. Set the format type to Mac OS Extended (Journaled.) Optionally, click on the Security button
    and set the Zero Data option to one-pass.
    5. Click on the Erase button and wait until the process has completed.
    6. Quit DU and return to the Mac OS X Utilities window.
    7. Select Reinstall Lion/Mountain Lion and click on the Install button.
    8. Upon completion shutdown the computer.
    *If your computer came with Lion or Mountain Lion pre-installed then you are entitled to transfer your license once. If you purchased Lion or Mountain Lion from the App Store then you cannot transfer your license to another party. In the case of the latter you should install the original version of OS X that came with your computer. You need to repartition the hard drive as well as reformat it; this will assure that the Recovery HD partition is removed. See Step Three above. You may verify these requirements by reviewing your OS X Software License.

  • Is there a way to down grade my Mac Pro 5,1 firmware so it will run Snow Leopard?

    If so will it still run Lion?    I believe this machine is the same hardware that ran Snow Leopard 6 months ago.   Brand new Mac Pro 5,1 two months old. 

    HURRAY!!!  Houston we have Snow Leopard!!
    FatMac your post of the firmware data got me digging deeper....   To sum-up
    Prior to the death of the old Mac Pro1,1.  I was in the process of re-building my emergency boot disks.
    As a result my Snow Leopard Emergency Boot Disk (SL EBD) was a fresh 10.6 install.
    The old MacPro died before I was able to update the SL EBD to 10.6.8.  This I of course forgot.
    The new MacPro would not boot from the old MacPro hard drive (10.6.8).  (It must have gotten taken out in the crash).  And obviously would not boot off of the SL EBD.
    Initially Apple told me that the new MacPro would run SL.  But later conversations with tech support emphasized that it would not and it was standard practice to not make new machines backward compatible.
    I assumed I was done-for.
    Thanks to FatMac's firmware info, I investigated deeper and found my SL EBD was only 10.6. 
    The 10.6.8 combo updater will not run from Lion.
    Now if I could somehow boot into Snow Leopard  so I could do an update.  
    I stumbled across a Carbon Copy Clone sparse image of my old MacPro 10.6.8 start-up disk that I had made DAYS before the crash and burn of the old MacPro.   (Am I lucky or what?)
    CCC'd the old sparse image on to a spare hard drive, restarted & Bingo!  I was running Snow Leopard! 
    Ran the 10.6.8 combo udater and updated my Clean Snow Leopard install.   Now I have a virgin copy of Snow Leopard to boot from. 
    I guess I can toss out my Leopard 10.5.6 Boot disk.
    Now I need to make a sparse image of the virgin Snow Leopard boot disk so I can re-install it at anytime in the future.
    Anyone know how to burn an 8 Gig sparse image onto to several DVD's for archiving? 
    FatMac,  the screen capture was the old fashoned way... I pointed a camera at it. 
    Thanks to everyone for their contributions.  
    Today was a good day!!!    

  • PSE 8 for Mac won't Install; running Snow Leopard 10.6.2

    Hi,
    When PSE 8 was released for the Mac, I bought a copy from Amazon.  I am running Snow Leopard 10.6.2 on two 24" iMacs and one MBP 15.3.  The Adobe installer would hang about three quarters through the installation.  I'm running PSE 6 for Mac without a problem.  I returned the software to Amazon without a problem.
    A month or two later I downloaded a trial version from Adobe's web site thinking perhaps the DVD I had gotten from Amazon was possibly defective.  Nope.  Same problem trying the trial version.  It just hung about three quarters through the install on all three machines.
    I'm running Photoshop Extended CS 3 with Snow Leopard and have no problems.
    What gives?
    Thanks,
    Linnie K

    Hi,
    I wouldn't know.  The first copy I bought from Amazon and returned.  The second one was downloaded from your web site as a trial and I removed all the bits and pieces after killing an hour with the installer.  I didn't think I could download the trial version a second time.
    I'm using a Mac with Snow Leopard 10.6.2.  My Photoshop Extended CSS3 and PSE 6 work just fine.  I'm afraid that if I deleted all you had suggested, I would have trouble reinstalling the two apps I just mentioned.  From what I've read on various forums,, Mac users (not all) are still having difficulty installing PSE 8.
    BTW, this is the only app I've had any problem installing on my system.  I deliberately waited for v. 10.6.2 to install the newer OS as there were earlier incompatibilities.
    Thanks,
    Linnie

    Ok; I'm not sure what you're doing.    36 hours is rather long.  Seems like a new migration.  Not what I intended.
    Here's what I intended: from the newly-migrated and apparently-corrupt environment, create a new user, not related to any existing user, nor any migration-created user, or any other user for that matter.  That is, use  > System Preferences > Users and Groups, authenticate yourself by clicking on the padlock, and then click the + and create a wholly new user.  Then log in under that user and establish the mail access.
    36 hours?  I'm wondering if there's an error or an exceedingly slow network here?  Or a really, really slow disk?  Or a sick backup?  (WiFi isn't the path I'd usually choose, either.)
    Failing the attempted second migration, I'd try a different tactic.  Does your existing (old) system work?   If so, I'd bypass the backup and connect an external (scratch) USB disk drive to the (old) sstem and then boot and use Disk Utility booted from the installer DVD disk or boot and use Disk Utility from the recovery partition or booted from a recovery partition created on some other external storage (details here vary by the OS X version and what hardware you have), and perform a full-disk backup of your original internal disk to (scratch) external storage.  (Make sure you get the source and target disks chosen correctly here; copying the wrong way — from the scratch disk to your existing disk — will clobber your data!)  In esssence, this will clone your existing boot disk.  Then dismount the (formerly-scratch) external disk, transfer it over to the new system, and use it as the source of the migration, by performing a fresh OS X installation on the new system.
    Target Disk Mode is also sometimes an option for accessing the disk for a migration, but that requires the right cable, and requires systems that have the same external connection; newer MacBook Pro systems use Thunderbolt for this, and older systems tend to use FireWire.  And I'm guessing you don't have compatible hardware.
    The details here can and do vary by your OS X versions and your particular Mac systems — if you'll identify the specific models and hardware, somebody might be able to better tailor the above (fairly generic) sequence to your particular configuration.

  • Can I run Snow Leopard and Mountain Lion on the same iMac?

    I have a late 2009 iMac with a 1tb hard drive running Snow Leopard.  Can I partion the hard drive and upgrade to Mountain Lion on one part and keep Snow Leopard on the other?  If not, can I partition my external back-up drive that I use for Time Machine to do the same thing?

  • Just installed snow leopard and office for mac - now my computer is running very slow.  Why?

    I've recently installed snow leopard and office for mac - now my computer is running very slowly - why?

    Which version of office did you install? If its 2008 the early version had some problems and you will want to update the office software to i think it is 12.3.0
    If it is 2011 you might want to do the same thing.
