Can I downgrade from pre-installed Lion to Snow Lepoard on Late 2011 MBP i7 2.4?

I've purchased a MacBook Pro Quad-Core i7 2.4 with pre-installed Lion (no installation DVD's included), but, unfortunately, found out that a big number of audio software doesn't run natively and malfunctions with this version of OS, meanwhile they worked flawlessly on my previous MacBook using Snow Leopard.
The question is: can I downgrade from pre-installed Lion to Snow Lepoard on Late 2011 MBP i7 2.4?

Thanks a lot for your reply. I ran into those numerous techy ways of downgrading, but I've found none addressing my particular model (I think I read something about 15", while mine is 17" and sometime it does make difference - because Apple love to keep secrets about what's inside). Since i've got zellions of audio plugins install, I'm trying to make sure that messing around with systems will lead to some fruitful result. So the new question: is there a way to make sure (I haven't found any tech spec threads naming the borderline between a "working variant" and "no-use-trying" variant) - is that just a matter of chance and doing it at one own risk, or is there still a way to make surefire decision?

  • How can I downgrade my pre-installed Yosemite OS X to Mavericks?

    So the hard drive on my Macbook Pro inexplicably crashed, and I had to take it in to get it replaced. The new hard drive meant that I ended up with Yosemite OS X instead of Mavericks, as I had previously, but I'm finding Yosemite to be terrible and it's greatly inhibiting me. Is there some way I can downgrade back to Mavericks OS X, despite it never being installed previously on my new hard drive?

    Boot into Internet recovery mode and reinstall the OS. If told you can't, then make a bootable backup/clone or Time Machine backup of your Yosemite installation, erase the HD, and reinstall the OS. It should put down that which came with the machine.

  • I want to re-install my Pre-Installed Lion Macbook Pro, but I can't get the Lion OS from App Store with my Apple ID. Please help, thanks!

    Hi, I want to do a clean re-installation of my end 2011 Macbook Pro which comes with pre-installed Lion OS. I go through the installation steps and after App Store verified my Apple ID, it prompted me that I did not purchase the Lion OS. I am very surprise to see this message which my pre-installed Lion Macbook Pro should have it. Please help and advise how can I get the OS? All other bundle softwares were in the purchase record except the Lion OS.

    That was my mistake - sorry - it IS Command-R to boot to the Recovery disk, not Command-D: I either just hit the wrong key or am just now coming awake from my nap.
    Let me see if I can just explain it in a few steps - I don't know of any link (but it would make a good User Tip):
    Create an up-to-the minute back-up of your internal hard drive using an external hard drive and Time Machine.
    Boot to your recovery partion - holding down Command-R on boot.
    Use Disk Utility to erase Macintosh HD - use one GUID partition and format as "Mac OS Extended (Journaled)". Unless you're selling the machine, there's no need to do a secure erase (which can take hours).
    After you erase the disk, re-install Lion from the same Recovery partition.
    After installation is complete, reboot, again holding down the Command-R keys to boot into the Recovery Partition.
    Restore your Time Machine back-up. This could take several hours.
    Reboot after restore and you're back in business.
    That should take care of everything - all you need is an Internet connection.
    Call back if I didn't explain things too well - at least I got the Command-R right this time!

  • Install Lion on second computer from pre-installed version on new laptop

    Hi,
    I just purchsed a new Macbook Air with Lion already installed - it is a great machine!
    Now, I have an iMac on my desk that is 4 months old.  I'd really like to upgrade it to Lion.  My understanding is that we're allowed to install Lion on a second machine.  But, since my only copy came pre-installed on my Macbook, I don't know how to do this?
    I've seen many tutorials about making an installation DVD or USB key from the purchased version of Lion.  These dont' seem to apply to my pre-installed version.
    How can I install Lion on my second machine?

    ...My understanding is that we're allowed to install Lion on a second machine.  But, since my only copy came pre-installed on my Macbook, I don't know how to do this?
    You are allowed to install on multiple machines in your house when you purchase from the Mac App store.  Pre-installed copies of Lion do not qualify since the purchase is not listed in your Apple account.  Think of it like how you would buy the "family pack" of OSX in the past.  Just that now it costs $29 instead of $49.
    If you're looking at the instructions on how to make a bootable DVD, then they're telling you to look for a specific file.  (Hint, hint.)  Since these Lion preinstalled Macs have just come out, it's going to take a while before people figure out where the files(s) are, and so have time to update their instructions.  This is assuming it's even possible since Apple has always prevented the disks supplied with a machine to work with anything other than the same model.  Only "retail" versions of OSX would work on multiple models of Mac, and what you download from the Mac App Store is a "retail" version of OSX.  So it would not surprise me if the files on the pre-installed Lion only work on the same model Mac as well.  (IOW, the installer may only work on 2011 MBAs since that is what you have.)

  • Can I install iDVD (only) from an iLife 11 CD on a new (late 2011) on-line MacBook Pro/Lion purchase that no longer included it?

    Can I install iDVD (only) from an iLife 11 CD on a new (late 2011) on-line MacBook Pro/Lion purchase that no longer included it?

    Purchasing iLife 11 on disk is an easy thing to do. ILife 11 will include iDVD.
    If you have iDVD on another Macintosh you can transfer it to your new computer. That procedure has been discussed here many times, if you do a search you will find that procedure.

  • How can I downgrade from 11.0 and re-install 10.7

    How can I downgrade from 11.0 and re-install 10.7

    First, reconsider your decision. 11.x isn't quite as user-friendly as 10.x, but it has pretty much the same functions are before (albeit in different places). Give it a few more days, and you might grow to like it. Future releases will only get better.

    Hi, been using mavericks for a few months and but am slowly getting dissapointed and frustrated with how slow it is.
    I have a imac i7 with 12gb of ram and a good graphics card but nearly all my software runs too slow. It is difficult to enjoy my time on the desktop.
    My question is can i downgrade from mavericks and install Lion or something? Seriously my G4 was faster!

    Use the backup you made before you chose to upgdade and follow here

  • How to make a image file from Pre installed Mac osx ? "PLEASE HELP :("?

    hey guys ..Thanks u for the time.
    So i have this eMac which has crashed and i have got may hands on another eMac.. and it works
    ... the only problem is.. I can take my eMac to the working eMac to do Target Mode or any thing...
    So Help me..
    My question is .. Is there a way to make a .DMG image file from pre installed mac osx OR
    Is there a way to may a recovery disc??

    You can use Carbon Copy Cloner to copy everything from the working eMac onto the non-working eMac while the working eMac is running. If your eMac will still do target mode into the working one, you can download the above software, select the booted drive as the source drive, and your eMac's drive as the target, however it is possible this will not work.
    When you say your eMac crashed, what exactly happened?  It is possible that the hard drive in your eMac failed or is failing, so in order to get it running again you would need to replace the hard drive.  On the eMac, this repair is somewhat involved, and you have to be very careful because it exposes the CRT, which has several areas which can be extremely dangerous to touch if not properly handled.  CRTs retain a great deal of voltage, even when unplugged, sometimes for weeks, and they can give you a nasty shock if you touch them in the wrong place.
    Also keep in mind that cloning from the working computer to the non-working computer will ERASE any data that you have stored on that eMac, so if you don't have it backed up anywhere, you may want to attempt that with target mode before proceeding.
    Good luck!

  • How can i downgrade from os x 10.9 to 10.7 without time machine

    can i downgrade from os x 10.9 dirrectly to 10.7?

    You should start a new topic thread, so as to get more exposure
    to your question; this is suggested due to the status of where you
    posted your item (now answered) will see fewer people with any
    answer; mostly those seeking answers like their own question.
    If your MacBook Pro shipped with a system later than the
    DVD version OS X 10.6 you have, the disc would not work.
    However, if the DVD you have is the Original OS X version
    the MacBook Pro came with, you could use it in much the
    same way as it worked before installing Mavericks 10.9.x
    By 'reverting' to Snow Leopard 10.6.8 you will essentially lose all
    of the content on the hard disk drive. I am not certain if you could
    even import anything from a 'time machine' device that had been
    created under the newer Mavericks 10.9 system. Since you have
    to boot the computer with the install DVD for 10.6, and erase the
    hard disk drive, reformat it to GUID and HFS+ (whatever default
    for Snow Leopard) and that would remove the Recovery partition
    on the computer's hard disk drive, and any other partitions.
    Insert the Snow Leopard DVD into the optical drive, and restart
    while holding the C key down, until the Installer disc is running
    the computer; this would be rather slow, as it reads from the DVD
    in order to build the Installer desktop, and access files to attempt
    an installation. It may also be testing the hard disk drive, etc.
    Once the computer is booted from the SL 10.6 install DVD, you
    can look into the Utilities menu (in top of screen, like in Finder
    desktop) to choose Disk Utility from the drop-down menu, and
    once you launch Disk Utility, note there are sections within it
    to choose from. You can choose Secure Erase (single pass) if
    you want to have the utility overwrite zeros on the entire HDD.
    This a bit longer then a basic erase & install. It wipes everything.
    If not, choose to erase all Partitions and be sure it does this.
    Afterward you would need to be sure it reformats the hard drive
    with a correct partition map & file type. GUID & HFS+ journaled.
    The tools are in the Disk Utilty that you run prior to the Installer
    itself, as there are options in the menu just like Finder desktop.
    Once the hard drive is erased, partition mapped, & reformatted,
    it should be easy to put an all-new system 10.6 on the hard drive.
    (That is, if the OS X DVD you have is a retail version, and if your
    computer shipped with a system older than the one on that DVD.)
    Should you choose to, an idea some suggest prior to upgrade
    and also prior to downgrade, is to make a full clone of the system
    that is running the computer on an externally enclosed hard disk
    drive (see carbon copy cloner, or superduper, clone utilities) so
    as to have a complete running system that can boot the Mac...
    If you had one of these prior to upgrading to Mavericks, it would
    be able to run your computer without re-installing. You could just
    use the clone utility, again, to clone it back to the wiped Mac HD.
    Or run Snow Leopard from the external, at a slightly slower rate
    given the USB 2.0/3.0 to an external is slower than bus speed.
    Not sure if this helps. However you may benefit from more
    exposure to your question in a new topic thread, and that
    could be in Snow Leopard, Mavericks, or this ASC section.
    There are advantages to posting in an OS X named topic
    since people with all kinds of supported Mac would see it.
    Hopefully you can revert, and also have some kind of a way
    to make a backup of any works you may need a copy of.
    The applications in Snow Leopard, older than Mavericks,
    may not like to handle files made with newer software.
    Though there is a cost to set up the ability to make and use
    full bootable system clones, the external drive, time, learning
    and testing the idea to see if you can master it before erasure,
    the results are worth the effort; since you then have a backup.
    A full backup, and it is a manual effort to make this kind, unlike
    the 'time machine' bits and pieces, this can bring back the Mac;
    if used with a time machine backup, too, could be opportune.
    Good luck & happy computing!

  • Lost macros downgrading from M. to Lion

    Hi all,
    Yesterday I downgraded from Mavericks to Lion (10.7), first deleting the disk and then using time machine. It worked like a charm. Just brilliant.
    What I did realize though, is that I am missing all my macro's (for Word 11). Is there any way I can retrieve them? Are they hidden somewhere or just lost?
    Would be a great help if I could recover them, I had a lot.
    Thanks and a fine day

  • Can I install Lion over Snow Leopard without erasing and restoring hard drive?

    Been reading a lot about downloading Lion. Recommended to back up hard drive to ext. drive, erase hard drive, install Lion and then re-install apps and files from ext. drive. Can I just install Lion over Snow Leopard without erasing all apps and files on hard drive?

    If you do an upgrade install then be sure to do this first:
    1. Repair the Hard Drive and Permissions
    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. 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.
    If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro 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.
    2. Make a bootable backup just in case. 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 backup drive. Source means the internal startup drive.

  • I can't boot from OS install USB drive Mac Mini Model 1176

    How I can't boot from OS install USB drive, Mac Mini Model 1176

    Thank you Eustace Mendis for your answer.
    I rebooted the Mac Mini holding the Option key down but it doesn't work. I used an USB drive with O.s 10.7 from Apple that I have used previuosly with other computers and I also tried with a CD install O.S 10.6
    It seems that the Mac Mini can't recognize the keyboard inputs and I tried with 3 different keyboards but still didn't work.
    I also reset the SMC and PRAM but I had no luck. Any clues?
