Install snowleopard over lion on a another partion

How do I do this I don't have any computers with snowleopard please help I want to install snowleopard  on another partion on my lionmacbook pro hoe do o do this

Assuming your MacBook Pro supports Snow Leopard and you have an SL DVD, you would first need to back up your system. Next, use Disk Utilities to create a 2nd volume (partition) for Snow Leopard (Mac OS Extended (Journaled)). Last, boot from your SL DVD and install SL to the new volume.
How old is your Macbook Pro and what OS came preinstalled?

  • Trouble installing Mavericks over Lion on iMac 12,2; hangs.

    Hi Folks,
    iMac 12,2 16 Gigs RAM, i7  4-core 3.4 GHz 1-TB HD for data, 1-250 Gig SSD for systems - running Snow Leopard on one partition and Lion on the other. (Full hardware description at bottom.)
    Purchased new in New Zealand about 14 months ago from Apple authorized reseller; no AppleCare. Not registered with Apple. No seerrious problems since, until this.
    Ethernet lan connection to Airport and then ISP's modem/router (Telecom New Zealand, . Fixed IP. No problems there, I think.
    Lots of USB stuff plugged in during install, but that shouldn't matter.
    Attempt to install Mavericks on Lion partition while booted in Lion partition failed.
    Attempt to install Mavericks on Lion partition while booted in Snow Leoepard partition failed.
    (Download to Snow seemed to work fine. Installer ran, finished in 20 minutes instead of 35, but when I restarted the computer the startup hung. Shutdown, restart, hangs. Every time.)
    Both installations failed with this hang. Restarts done with verbose logging on show the following, repeating ad infinitum (I stopped counting after it got over 5,100 lines -- no I didn't watch 5,000 lines scroll, I went away for a snooze):
    invalid sandbox profiile for pid <number> (invalid regex)
    Nothing here in the forums, or on the InterWebs about this error or much about a hanging install (which has been identified as one of Mavericks' problems) except to say wait forever (I  think 5,000 lines of verbose logging is forever) or try the install again. I have tried the install again; it hangs at the same point every time.
    There is some stuff on the hacker sites about sandbox and this error, but only for earlier OS versions. The fix for them was to replace the sandbox.kext. I'm going to boot into root in Snow Leopard partition so I can do things to the Lion partition, and change that kextfile?! Yeah, Riiiggghhhhttt. NOT.
    I suppose I could try the install with all USB stuff disconnected -- but I don't believe that's it.
    I suppose the fact that the Lion might not have had the latest software updates to it before I tried to install Mavericks might have something to do with it. I don't believe that's it (certainly is shouldn't be).
    Final recourse might have to be wiping the Lion partition (full erase and clean install) (it doesn't have any critical data saved on it; I do all my work in Snow on the other partition, the Lion is for experimenting).
    Anyone have any ideas?
    TIA and cheers,

    Sorry, bad news for you, depending on your setup.
    The answer (provided by an Apple higher-level tech for which I paid -- no Applecare) was that they don't have a clue, but a clean install works.
    Yeah, Thaaannnnnnnkkkksss. Knew that.
    Clean install (almost) always works (worked) for 25 years.
    You don't say if your kit has everything on one partition, or there are more than one.
    If you have a big hard disk that's not full, has lots of room, but only one partition, with 10.8 you can dynamically create a new partition without losing data. I don't have the details of the process handy, but it's pretty straightforward.
    Then, with the Mavericks installer on the 10.8 partition, and booted to that partition, you can install Mavericks on the other partition (with administrator account). You could use the migration assistant (or whatever) to bring your data over from the 10.8 partition to the Mavericks one. However ...
    You might also want, if your hard disk isn't huge, and you don't have two drives of whatever type in the machine, to make the new partition just big enough for the OS and apps, and keep the data on the 10.8 partition.
    You can tell the Mavericks instance to use the other partition as your Home directory, instead of the Home directory on the Mavericks drive.
    If you have your OS and data on the same partition, and you don't have enough room on your disk(s) for the above procedures, then your best solution would likely be make a Carbon Copy Clone of the drive, wipe it completely, and install Mavericks from some external source other than another partition with another OS, and migrate your data back.
    There is stuff on the Web about making a bootable Mavericks install disk on a flash memory stick.
    But whichever way you end up doing it, you will have to boot into a clean OS on a different partition or disk from the target Mavericks install partition or disk.
    Last caveat: it may be difficult, but not impossible, to maintain your, or multiple users', identity and accounts and where they point, as well as your online IDs.
    Hope that helps a bit. Don't give up, but do take precautions (a CCC backup or a Tiime Machine is always wise anyway) and write everything down as you go.
    FWIW, I'm not using the Mavericks partition for anything, not even experimentation. I'm still using my Snow Leopard, because it works fine (finally) and is the only way to run Eudora. Until, that is, I solve the problem of running 10.6.8 server in a virtual machine in the Mavericks partition so I can run Eudora under Steve's nose with impunity, and so seamlessly it seems to be running under Mavericks, with full integration (through Parallels).

  • HT2956 installing leopard over lion

    how do I reinstal leopard over lion?

    You need to either revert to a backup you made prior to installing Lion or install Leopard onto a blank partition or drive. Repartitioning a drive with Boot Camp set up on it may disable that.

  • Installing SL over Lion

    In November I bought a refurbished 13"Macbook Pro (early 2011) with the specific intent to instal Snow Leopard over Lion in order to keep on running legacy software. Unexpectedly the computer comes with a firmware update which does not allow me to boot from my Snow Leopard CD (nor over firewire). Apple support says that the ony work around would be for me to purchase Lion for the machine I am using now (an identical 13" MBP) and use it to partition the new (refurb) computer's HD and install Snow Leopard on the partition. Has anyone out there done that and can you give me some ideas about how to approach this interesting problem?

    What Snow Leopard DVD are you trying? A retail one won't work. It has to be the same gery coloured one that would have shipped with it when it was new.
    Call Apple Support back, give them your Mac's serial number, and ask them to send out a set of replacement original install discs for your Mac.

  • Can I install Snow Leopard over Lion to install old software after hard drive crashed?

    My hard drive crashed and I lost everything.  I have a new hard drive, but when the repair shop installed my operating system, they installed Lion and I no longer have my prior updates.  My computer had been updated a few times.  I have a lot of software that only can be installed up to 10.7 such as Adobe Photoshop Elements 10, Office Mac 2011, etc.  I was wondering if I installed Snow Leopard over Lion, would I lose Lion?  Should I install Snow Leopard and then Lion again?  I don't want to damage my like new computer and I don't want to have to go out and buy all new software.  Is there a solution?  Thanks in advance!

    Sounds complicated!  If I repartition the drive and install Snow Leopard onto the blank volume, will Lion still be there?  Or, will the computer basically have two operating systems that I have to go back and forth from.  Is this something a novice like myself can do?

  • I inadvertently installed the mountain Lion Safari over my existing copy not realising that it would not work with OS 10.7.5 and now I am unable to use it .

    I inadvertently installed the Mountain Lion Safari over my existing copy not realising that it would not work with OS 10.7.5 and now I am unable to use it .
    Can someone suggest a solution please.

    It should work, but it's an unmitigated mess. Simplest is to boot into recovery mode and reinstall the OS.

  • Installing Mavericks over Mountain Lion

    I try to install Mavericks over Mountain Lion but keep getting this message: Unapproved caller, securityagent may only be invoked by Apple software.
    Now I am stocked and cannot do anything :-(
    Any suggestions?

    Dang! that was so NOT cool. Same thing happened to me and feel lucky to have found this thread.
    I was stuck in a loop of that dialog popping up saying "Unapproved Caller". I tried clicking OK repeatedly and it still kept popping up.
    Seeing the comment about Safe Mode, I took the gamble and held the power switch on my 27" iMac until it powered off, waited a moment, then pushed the power button again and as soon as the chime sound happened, held Shift key to boot in Safe Mode and that worked just like it did for @Bart2904.
    How in the world would an average user know how to recover from such a situation - it would be bricked computer and a trip to Genius bar. Again, not cool.

  • I accidentally downloaded lion. I did a timemachine back-up and tried to reload snow leopard. It will not accept. How do I re-install snow leopard over lion?

    I accidently installed lion on my mac book pro. I did a time machine back-up. When i try to re-install snow leopard, it won't take. Any suggestions on how to install snow leopard over lion?

    Accidentally, eh? How, might I ask?
    Downgrade Lion to Snow Leopard
    1.  Boot from your Snow 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 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. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, set the partition scheme to GUID then click on the OK button. Click on the Partition button and wait until the process has completed.
    4. Quit DU and return to the installer. Install Snow Leopard.
    This will erase the whole drive so be sure to backup your files if you don't have a backup already. If you have performed a TM backup using Lion be aware that you cannot restore from that backup in Snow Leopard (see below.) I suggest you make a separate backup using Carbon Copy Cloner 3.4.1.
    If you have Snow Leopard Time Machine backups, do a full system restore per #14 in Time Machine - Frequently Asked Questions.  If you have subsequent backups from Lion, you can restore newer items selectively, via the "Star Wars" display, per #15 there, but be careful; some Snow Leopard apps may not work with the Lion files.

  • I cannot install OS X Lion on my MacBook Pro. Installing time is in negative hours. (-2,147,483,648 hours)

    At first, my macbook couldn't start up. It only displayed apple logo with a spinning wheel on grey screen for hours and hours. Then I decided to reinstall the OS. I tried so many times to install but the installing time said thousands of hours remaining to complete . I left the computer for days but  it didn't install OS. I tried that connecting the Ethernet cable as well but it didn't work.  Then I took out all my important files by connecting it to another macbook and formatted the hard drive. Then tried to install OS again.  But still didn't work. I checked on you tube and changed the hard drive cable as well. Still didn't work. I cannot install OS X Lion on my MacBook Pro.

  • Kernel Panic after installing Mac OSX Lion

    I have a late 2009, 15" Macbook Pro that I've upgraded to mountain lion about three weeks ago and when I upgraded the first time I kept getting kernel panics like no tommorrow. I used my flash drive which had lion uploaded to it to "downgrade" to lion in case this happens. I also had mountain lion on the flash drive to so I did a clean install of mountain lion through my flash drive. After that, kernel panics still seem to appear. I got frustrated and called apple support, and lets say that after many hours of testing, installing, and configuring that they just told me to simply go to an apple store, which was a two hour drive from Pine Plains, NY to Danbury, CT only to have them reenstall mountain lion (again) through a network. When I finally got it back and tested it for an hour I thought things would be fine... But lo and behold, another kernel panic appeared. I've taken the liberty to track the programs that I've installed and used during the testing as well as the kernel panic that was reoccuring.

    I'll try to figure out how to read this as soon as possible, but until then I need your help to solve this problem.

    That panic was not caused by third-party software.
    If the panic is recurrent, the possibilities are (1) a damaged OS X installation; (2) a hardware fault, which could be internal or in a wired peripheral device; and (3) an obscure bug in OS X.
    You can rule out the first possibility by reinstalling the OS. Probably there will be no change. In that case, make a "Genius" appointment at an Apple Store to have the machine tested. You may have to leave it there for several days. There isn't much point in doing this unless you can reproduce the panic, or unless it happens often enough that it's likely to be repeated at the store. Otherwise you may be told that nothing is wrong.
    Print the first page of the panic report and bring it with you.
    Back up all data on the internal drive(s) before you hand over your computer to anyone. If privacy is a concern, erase the data partition(s) with the option to write zeros* (do this only if you know how to restore, and you have at leasttwo independent backups.) Don’t erase the recovery partition, if present.
    *An SSD doesn't need to be zeroed.

  • How do I install OS 10.7 NOT 10.7.5 on a mac running Snow Leopard 6.8  i.e. where can I find the original install app for Lion OS 10.7.0?

    I'm running 10.6.8 Snow Leopard fine on my MacPro1,1, Dual-Core Intel Xeon, 2.66 GHz  Mac, but I need to install Lion 10.7.0 to run a program I need.How do I install OS 10.7 NOT 10.7.5, because I get this message when I try to install 10.7.5, which I've downloaded:"This update requires Mac OS X version 10.7." on a mac running Snow Leopard 10.6.8, So i need to install the original 10.7.0 over the 10.6.8  i.e. where can I find the original install app for Lion OS 10.7.0? The original Lion 10.7. is not avaialable for purchase from the App store or anywhere,  even C-Net . Where can I find it to purchase?
    Also it seems I cannot install Mountain Lion over 10.6.8 as advertised. When I go to purchase I get this message: "We could not complete your purchase. OS X Mountain Lion is not compatible with this computer."   I think my computer can handle it (specs above) Are there any workarounds to this?

    If you're getting a "This update requires Mac OS X version 10.7" message, than you have the updater and not the full installer. Go to your Purchases section of the Mac App Store and you should see the full version there. But it may be 10.7.5, though in my system is shows as being from 2011 which would appear to be the original version.
    As to Mountain Lion, that's supported only on the Early 2008 Mac Pro or newer.
    Regards.

  • While intending to perform a clean install of Mountain Lion while continuing with old apps and files, is it a waste to restore a backup that was made while running Mountain Lion as an UPgrade from Lion?

    While intending to perform a clean install of Mountain Lion while continuing with old apps and files, is it a waste to restore a backup that was made while running Mountain Lion as an UPgrade from Lion?
    Originally I was running Mountain Lion as an UPgrade from Lion. I created a backup in Time Machine, performed a clean install of Mountain Lion, then I proceeded to use Time Machine to restore the back up.
    When thinking about the essence of a back up restore, it occurrs to me that for all I know, I may have just wated my time IF Time Machine also restores all the old unneeded files that remain from Lion after an upgrade.
    Since the backup was made while running Mountain Lion as an upgrade from Lion, did restoring this backup defeat the purpose of a clean install by reinstalling old Lion files?
    If so, how can I re-do the last portion of the process so that I get all my home-folder files and apps back without the full bulk of old Lion files? Migration assistant I'm guessing?

    Hello John!
    Thank you for your response which solved my problem. For other users who may stumble upon this, I'll clear up the confusion and share how I solved the problem with your help; When looking for answers to my computer problems, finding unresolved questions where person B offers a solution and person A never comes back and says "That worked, thank you.", it demonstrates a "k-thnx-bye" user mentality that leaves others with the same problem lost. Without further ado:
    It is not clear what you did because the meaning of "clean install" is vague. You can erase a volume and install an OS which leaves none of its previous content intact,
    This is what I did: I erased the volume leaving no previous content intact, while then installing OS X Mountain Lion.
    or you can upgrade an existing OS (or reinstall the same one) which does not alter your user - installed files.
    An upgrade to Mountain Lion from Lion is what I started with initially before erasing anything. This was undesirable. Since this can cause Macs to run slower (especially whereas I'm using a mid-2011 Mac Mini), my goal was to go from operating within an upgrade to Mountain Lion, to operating within an installation of Montain Lion that was not preceded by any other oprating system.
    Hence a "clean install of Mountain Lion while continuing with old apps and files" is confusing.
    Well put and understood. What I should have said was:
    1.Erase the volume
    2.Install Mountain Lion clean
    3.Confirm that Mountain Lion is functioning properly
    4.Proceed to use either Time Machine or Migration Assistant to Import/Migrate/Copy over only two things; My old apps (That had been stored originally in the designated Applications folder) and all files and folders originally stored in the home folder under users.
    If you restore from a Time Machine backup then all modifications that occurred subsequent to that backup become erased. It renders moot any OS X upgrade performed subsequent to that backup.
    That makes sense and is just as I later suspected.
    If so, how can I re-do the last portion of the process so that I get all my home-folder files and apps back without the full bulk of old Lion files? Migration assistant I'm guessing?
    Yes.
    This is what I did and everything works perfectly. Thank you so much once again!
    -Chris

  • How long does it take to install OS X Lion?

    How long does it usually take to install OS X Lion?
    Thanks.

    Typically 20 minutes or so for a clean install. Longer for a reinstall over an existing system - 45 minutes to an hour.
    These times do not include time for downloads. A reinstall requires downloading Lion which can take several hours depending on the internet connections at the time.

  • Install Solaris10 over network.

    I have one sinfire v245 box which is in remote location (DR site). I want to install Solari10-u5 on it.
    I can't travel to remote site due to some restriction.
    Presently Solaris10-U1 is installed in the box.
    I have telnet/SSH access to Solaris-OS, and i have SSH access to it's "Advanced Lights Out Manager".
    There is no one in remote location who can insert Solaris10-u5 media.
    In this situation, is there anyway that i can freshly install Solaris10-u5 on it ?

    Ok. I learned the way how to install Solaris over network.
    I have created a install server on another solaris box, the client and this box are in the same network.
    I am trying to install the client, i am getting this error on the client continuously . Any idea how to solve this ?
