How can I revert to Snow Leopard on my Air?

I have a macbook air running lion, a snow leopard install CD, and a mac pro also running lion. How do I install snow leopard on my air from that CD? What happened to the utility that did this stuff? Target disk mode requires a firewire port... What am I supposed to do?

Here's a suggestion if you don't wish to look for the utility on your Snow Leopard DVD. Get an 8 GB USB flash drive. Format for OS X and clone your Snow Leopard DVD to the flash drive using your other computer.
Drive Preparation
1. Open Disk Utility in your Utilities folder.
2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. 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 Partition 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.
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 USB flash drive. Source means the Snow Leopard DVD.

  • How can I revert to Snow Leopard from Mountain Lion on a 2013 iMac?

    I have a brand new 27" 2.9Ghz iMac, bought a few days ago, equipped with Mountain Lion. I'm using it for recording, and at the time, my recording software and hardware are incompatible. On Snow Leopard, however, it all runs flawlessly. I know I can't simply revert to Snow Leopard, as there is some sort of firmware that blocks these types of downgrades. Can I partition the internal hardrive and install Snow Leopard and boot from that partition? I have no real use for Mt. Lion for the time being, so I wouldn't need to boot them both simultaneously or even go back and forth. I just want Snow Leopard...any help would be much appreciated. Thanks

    Welcome to the Apple Support Communities
    You have different problems with a Late 2012 iMac and Snow Leopard:
    1. The firmware doesn't allow you to run it.
    2. Snow Leopard isn't compatible because it hasn't got the drivers for the hardware of the iMac. Furthermore, you can only run OS X 10.8.1, 10.8.2 or 10.8.3 on a Late 2012 iMac at the moment, because older versions haven't got the drivers it needs.
    3. It's illegal.
    As you can see, you can't run Snow Leopard natively. If this is a requirement, I suggest you to return your iMac and search a Mid 2011 iMac with Snow Leopard (there are some Mid 2011 iMacs that came with Snow Leopard, although most of them came with OS X Lion). If you don't find anything, buy a Mid 2010 iMac.
    Another possibility is to buy Snow Leopard Server and install it on a virtual machine, but I doubt it's legal

  • How can I revert to snow leopard

    I installed Lion. It took several hours!
    I found out after, that several softwares I was currently using do not work any longer (FileMaker, Excel, Word).
    Can I downgrade now? Or would it be possible to run both systems on the same machine?
    I have previouly saved my disk with Time machine.

    You can downgrade, but it's not easy.  Search these forums for "revert to snow leopard" for numerous answers.
    However, MS Office can be made functional by simply upgrading to Office 2011.  Also, my ancient copy of FileMaker Pro 8.5 seems to be working fine in Lion.  What version are you using?  Of course, the ultimate solution would be to simply upgrade FMP as well.  If you're going to upgrade your system, you're going to also have to upgrade your other software from time to time.
    To run both systems, you could create another partition on your hard drive with Snow Leopard, and then choose which system to boot into.  That would be inconvenient, though.  You'd be better off to simply commit to Lion and upgrade your other software or bite the bullet and revert to SL.  Of course, if you do the latter, you're stuck with that machine and that system until you ultimately are forced to do the former by hardware failures or whatnot.

  • Can i revert to snow leopard from lion without a time machine backup?

    can I revert to snow leopard from lion without a time machine backup?

    You can with a Snow Leopard DVD, but if you don't have that or a Time Machine backup there's no way.

  • How can I re-install Snow leopard having installed Lion? The disk supplied states that I cannot use the version of 'Install Mac OS X'...HELP!

    How can I re-install Snow leopard having installed Lion? The disk supplied states that I cannot use the version of 'Install Mac OS X'...HELP!

    None of the instructions usually given for downgrading seems to mention the fact that you will lose some data in built-in applications, including at least Mail. When you installed Lion, your Mail database was converted from the format used by Snow Leopard's Mail to that used by Lion's Mail. There is no way to reverse that conversion. Therefore, you will lose your entire Mail database. If your messages are all stored on a remote server, that may not be an insurmountable problem, but otherwise you'll have to restore from the last backup you made before the upgrade, and then you'll still lose all changes to the database made since that time.
    Another fact not often mentioned is that downgrading is usually the worst possible solution to a problem with Lion. But that's the answer to a question you didn't ask.

  • I have Mac OS X 10.5.8.  How can I upgrade to Snow Leopard?

    I can't find any information here.
    Any info would be greatly appreciated.
    Thanks

    Your machine is likely too dated to run 10.8 at all , or if it does will run slow.
    It won't run your PPC based software or hardware drives for external hardware.
    10.6 will run your PPC software and likely is best for that machine performance speaking, Software Update to 10.6.8 and stay there.
    You better do your research first.

  • How do I revert to Snow Leopard from Mountain Lion? I do not have the setup disk that came with my MacBook but I do have the Snow Leopard software.

    I upgraded to Mountain Lion and very much regret this move.  I cannot use Parallels or Bootcamp for Windows XP which I need for some of my 'older' accessories.  How do I revert from Mountain Lion back to Snow Leopard?  I have the Snow Leopard software but I do not have the original setup software disk that came with the MacBook (leant to a friend and never seen again).

    If you do revert to Snow Leopard, be aware of this "feature" I used with my 2009 MacBook Pro:
    When it had the original OS (Leopard, I believe) I set up Bootcamp with Windows XP.  I also installed Parallels and use the Bootcamp partition for Windows XP within Parallels.
    I then upgraded to Snow Leopard and all was fine.
    I then upgraded to Lion and still my Bootcamp partition works for Windows XP and also for Parallels.
    I have not upgraded to Mountain Lion so I cannot speak to whether or not the Bootcamp paritition of Windows XP will continue to work.  If you do and it works, LET US KNOW!

  • How do I revert to Snow Leopard?

    My other half has just installed Lion and did not realize that his MS Office and other software would not work. Naturally he has no backup so how do I go about reverting his machine to Snow Leopard?

    In Apple Mail pull down File > Import Mailboxes. This will open a dialog with one of the options being MS Entourage. I don't know what the process looks like from there since I've never imported from Entourage but this may be a solution for you. Although the dialog does say Entourage will launch, so it may not work. Worth a try, though. 
    The process isn't always perfect, and can take a while depending on how much email and other data is in there. However, there might be reason for using Entourgage/Outlook rather than Apple Mail/iCal/Address Book. Certainly another option worth considering though.
    I have migrated many users down this road and can tell you that there can be a world of hurt at the end if there are any issues with the main identity, (and being Entourage there are always issues with the main identity, unless you've only been using Entourage since yesterday, or less)
    Sadly, I've found this to be the case. If you can manage without Entourage/Outlook it is probably better to do so. What better time to make the transition?

  • How can I Downgrade to Snow Leopard and keeping all 3rd party apps?

    New to MacBookPro and really happy. With Lion...not so much. I want to downgrade to SL, however, apparently I must reformat the hard drive. Here´s the real question: If I have a backup of my entire HD with the user, docs and all the apps I have installed (on Lion), once I downgrade to Snow Leopard, can I just move all my apps from the back up disk I have made of my Lion-Running hard drive? In other words, How can I downgrade without having to reinstall every single third party app I have?

    First, how new is this Mac?  A Mac as a rule cannot boot to an older operating system version than that with which it was originally supplied.  In other words, if this is a new MBP that came with Lion then you probably cannot get it to boot to SL.
    Some applications (and I take it you do mean full "applications" rather than "apps" which are mobile device programs -- it helps to be clear o terminology) can just be dragged from place to place.  Others, notably Adobe and Office, install things all over the place and unless you are good at finding hidden files with obscure names in 10 different places you will just have to re-install them.

  • Can I revert to Snow Leopard? Lion took my Office

    I have two Macs - one an iMac, the other a laptop MacBook Pro.
    Both came with and run well on Snow Leopard 10.6.6
    I downloaded OS X Lion for the laptop and lost my Office 2004 and Parallels 6.
    Can I revert to a Backup from pre-Lion?  Do I need to do a clean install and lose all my downloaded apps  eg Pages?
    My iMac is as I want but it is frequently monopolised by She Who Must Be Obeyed who uses it alongside her work-from-home computer.

    Hello:
    "She who must be obeyed"  That broke me up - TY for the chuckle! 
    Anyway, the way I would proceed would be to restore the system from either a Time Machine bakup or a bootlable clone.  I don't think you would be able to reinstall OS X 10.6 on a system that has already been updated to OS X 10.7.
    Barry
    P.S.  I encountered the Office 2004 issue myself.  I decided that Office 2011 was not worth $150, so I moved to iWork.  iWork included a word processing program (Pages) which is fully compatible with Microsoft's Word.  I like it better, but that is just my own reaction.

  • HT1338 how can I upgrade to snow leopard

    I'm trying to get a new HD camcorder, and it seems that my iMovie is old, so I'm trying to upgrade my Mac software.  I'm still running 10.5.8 and I can't find anything anywhere about how to get Snow Leopard or Lion or Mountain Lion or whatever animal is currently the most recent version.  LOL

  • How can I upgrade to Snow Leopard with a broken cd drive?

    I recently bought the Snow Leopard 10.6.3 cd and was looking forward to the upgrade. I forgot my cd drive is broken. How can I get around this? I tried zipping the file on a friends computer and unzipping on my computer (so I could fit the software on a thumb drive). Not successful. Other ideas?

    If you have Mac or PC which has DVD drive, Remote DVD/CD drive could work.

  • How can I upgrade to Snow Leopard or Lion from Leopard 10.5.8?

    I can't find any way to get Snow Leopard from the apple store. It is on Amazon for $100+ and there are lots of fake ''free'' downloads online, but I don't want to use them?
    Is there any ways to get to Snow Leopard or Lion from this old opperating system?!
    My mac is a 2008 Macbook Pro.
    Thank you!

    Hi,
    I just bought the iphone 5 but have a 2009 Macbook Pro so was running 10.5.8. Needed to upragde to snow leopard then to mountain lion. S.L. is no longer available in stores. The guy in the shop told to cal apple support (0800 048 0408) but was skepitcal. Amazin was quite expensive so I ended up ringing just to check... TOTALLY WORTH IT! Got it for £13, when I would have paid about £70. Apparently they are trying to encourage people to get SL so they can get the icloud.
    Ring up! Honestly, their customer serivce was so helpful and lovely. Whole episode has reminded me why I love Apple.

  • How do I revert to Snow Leopard from Yosemite on late 2008 MacBook with no optical drive?

    Late 2008 MacBook. I don't need to back up, just to go back from Yosemite to Snow Leopard without a working optical drive.
    Thank you.

    If you have a Time Machine backup from Snow Leopard, then use it to restore from. Other than that, you will need to get an optical drive and run your install disks that came with your computer. Of course, you will need your Snow Leopard updater if you still have it since you can't get it from the App Store.
    I may be wrong about it not being available. I found a like from apple where you can still purchase it. It may still work.

  • How can I open a Snow Leopard Stickies Database on Tiger?

    I have a problem. My MBP running 10.6.x Snow Leopard is in the shop getting fixed. In the meantime I am using my backed-up files on an iBook running 10.4.11 Tiger. I desperately need some data from my Stickies on the MPB, where the Stickies Database was created in Snow Leopard. But Stickies on 10.4.11 will not open the database. Any idea how to recover that data?

    I just solved my own problem:
    Turns out that, when the Stickies app is closed, the StickiesDatabase file shows up in user/Library
    Just copy and paste in same location on new computer, 10.6.4 or earlier.
    Works like a charm (for me)
    thanks
