Downgrade Snow Leopard to Leopard

Hello all,
is it possible to downgrade mac os x 10.6.3 become 10.5?
i have problem using snow leopard,so i want return to 10.5.
anyone can help how to downgrade?
thanks

As Allan has stated, you cannot have the combination of hardware and OS that you claim to have, as Snow Leopard will not run on any G5 Mac.
First, what system did your machine come with? If it shipped with Snow Leopard (10.6.x) pre-installed, you cannot install Leopard (10.5) on it:
http://support.apple.com/kb/HT2186
Second, if it is capable of running Leopard, what disk are you trying to boot from? If it's a gray disk for a different machine, that won't work. You must either reinstall from the gray disk that came with the machine, or you must install from a retail Leopard disk.
Third, most people who want to downgrade, in my experience, don't actually need to. You need to spend some time trying to troubleshoot your system. As you say in your other thread, you have one machine running FMP 8 under SL without problems while it crashes on the iMac. This means it is not an issue with SL, so the only problem you've made us aware of is not a problem that requires downgrading.

Installing Lion on Snow Leopard Server

I have mac mini server running snow leopard server. I want to install Mac OS X Lion on it.
I have purchased Lion through App Store, but while installing on mac server it asks for Lion Server.
I am not using any server features as of now, Can I downgrade snow leopard server to client and instal Lion on it?
or is there any better way of installing Lion on Snow Leopard Server...
Thanks,
K

No easy way unfortunately.
OS X Server gets its fingers into all parts of your computer. You'd have to go in an manually remove hundreds of files, and replace them with their counterparts from the non-server version.
It would be MUCH easier to back up your home folder and any additional files you need, then nuke and pave with Lion non-server. Restore your info, and you'll be back up and running.

Mid 2010 Macbook Pro (7,1) - Downgrading from Mountain Lion (10.8.3) to Snow Leopard

Hi everyone!
I am looking for some help with downgrading my macbook pro from ML back down to SL. I'll start off with some information about my case:
I bought this computer mid 2010 - I believe in July, if that matters. It is a Macbook Pro 7,1 model. The computer came with two disks, one being the Snow Leopard 10.6.3 install dvd, and the other being the applications install dvd. I do still have these dvd's, sitting beside me as I type this. Just like many others, I upgraded my computer to Lion, and from there went to Mountain Lion. I have been on Mountain Lion for several months now, currently running 10.8.3. I know a lot of you out there are disappointed with this OS, and many have experienced significant adverse effects on the overall performance of their computer. That being said, I also know that a lot of you have not had these sorts of issues running the OS. As you can tell, I mysef fall into the first category, as I have not had the greatest experience with it. It just seems to tire out my computer at activity levels which, on Snow Leopard, would not be problematic. I say tire out here in that my computer will overheat, slow down, and even sometimes crash (the crashes primarily begin with the spinning rainbow wheel, attempts to quit / force quit the applications I am running, followed by complete and utter frozenness). When this happens, I have no choice but to press the power button until the computer shuts off, then I restart, occasioanlly taking multiple attempts because of kernel panics the first one or two times. Who knows why this happens...I upgraded my RAM a couple months ago from 4GB to 8GB, which has seemed to help some but not fix the problem entirely. So, I have been wanting to downgrade back to Snow Leopard.
Ok so, I have made multiple attempts at this. For starters, I can tell you that the computer simply will not boot from the Install DVD (it is the one which came with the computer, not a retail version or anything like that). Additionaly, I cannot restore the SL DMG file from the dvd, neither to my hard drive nor to a USB drive. Because of this, I ended up trying this: I downloaded the snow leopard installation files (I believe just the content of the DVD ripped from the disc) via a torrent. I then got a 16 GB USB flash drive, wiped and formatted it (Mac OS Extended (Journaled)), and copied to the USB drive the install file I downloaded. I'll also note that I have done the same thing for Mountain Lion, copying the install file from the app store to a separate 16 GB USB drive. Ok, onto the results of my attempts at downgrading:
Each time I have tried to downgrade, I have taken the following step:
1) Power down the computer
2) Insert Snow Leopard USB drive
3) Boot up the computer, holding the option/alt key
4) Selecting the Snow Leopard USB drive
     -It would successfully boot from the USB, and would bring me to the language selection window, as expected
5) After selecting English, the window gives me the option to continue with the install, or access any utilities, and I would go to Disk Utility
6) I selected the internal drive in Disk Utility (the whole drive, not the indented partition), and I went to the partition tab, partitioning the drive to have 1 partition, Mac OS Extended (Journaled), erasing the current partition
     **Note: I have not tried this, but I feel like maybe If I were to first Erase the drive, opting to zero out all data (1 pass) in the security options, then partition the drive the same way as I did in step 6, perhaps the installation would go smoothly without returning any errors...thoughts?
7) After step 6, I would return to the install os x window and begin installation of snow leopard.
     -Every time I have done this, the install has returned an error about mid-way through, and I would be prompted to restart and try installing again
8) Now having a non-booting computer, I would end up powering down, swapping out the snow leopard usb with my mountain lion usb, booting from that, partitioning the drive the same way as before, and reinstalling mountain lion
     -This beings me back to square 1. A working, booting computer on Mountain Lion...
I believe that my issues surrounding the use of my install dvd (that came with the computer) are caused by a bad optical drive. When in mountain lion, if I insert the dvd, it will read it, but it will do so very slowly. For example, after inserting the dvd and the install os x window coming up, if I select optional installs or instructions, each of these folders would open, but take a very long time to display their contents. It also is a struggle to get the disc to eject in this situation.
So, if anyone has had a similar situation and came out on top, I would truly appreciate your help!
Thanks guys,
Nick

How to Downgrade to Snow Leopard from Retail disk

Hi there
We have a new iMac at work bought through Apple's refurb site. It is running the latest version of Lion with all firmware updates, etc. It is replacing a G5 running Tiger.
The problem is this – it is supposed to be running Adobe CS5, but also CS4 (and Office would be handly also)
We have other macs here, some running Leopard, some Snow Leopard, but the Adobe apps are not happy at all in Lion, and InDesign CS4 crashes all the time and won't even print without jumping through a million hoops (obviously the Office 2004 app won't run at all).
Due to the level of issues we are having with Lion (and the reliability of the all the software under Snow Leopard) I am looking to downgrade to Snow Leopard.
I have a full retail version of Snow Leopard (10.6.3), but the Lion system won't boot from the disk, it just gets to the grey screen, and beeps three times. I presume this means that there isn't the required drivers on the disk to run the hardware, or there's a firmware update that doesn't allow installation.
Am i totally stuck with this OS? I was looking to install Snow Leopard on a partiton, but when i run the install disk from the Lion desktop, it reports that I can't run it because 'I have Install Mac OS X 23.1.1.'
I would really like to just have Snow Leopard on my iMac, or failing that, Lion on a small partition, and Snow Leopard and all the programs on the larger partition that I would boot from.
Any ideas how I can get this done? Adobe CS suite is just rubbish on Lion macs, and runs worse than on my old Tiger mac.
Thanks in advance,
M.

oh right - so clone Mac B onto Mac A HD in taget disk mode using SuperDuper (or Carbon Copy Cloner), then i'll be able to boot Mac A in SL.
I understand that Mac A wouldn't boot, I was going to make Mac A's SL partition the start-up partition for Mac B, and then try and install OS updates to 10.6.8 from Mac B. Once updates are installed - change Mac B's startup disk back, and then surely Mac A would be able to boot all on it's own...
I'm not sure if this would work in Target Disk Mode, but if you succeed in cloning Mac B to Mac A, you may be able to apply the Combo 10.6.8 update to Mac A while booting from Mac B. The key is that the Combo updater may be able to customize the Snow Leopard installation for the hardware it's actually being applied to. Unless I missed it, we don't really know which iMac you have since it's a refurb. According to Mactracker, only the Late 2011 21.5" comes only with Lion and might not accept Snow Leopard at all. At the same time, it has the same Model Identifier as the Mid 2011, which came with 10.6.6 or 10.6.7 so it might work.
If at that point Mac A does boot in Snow Leopard, I'd advise running the 10.6.8 Combo updater again while booting from Mac A just to be safe.

Downgrade to Snow Leopard with Time Machine - and then, what?

So I am making Time Machine backups on a regular basis. Almost daily.
The last one when I was running Snow Leopard, dates back from December 25th, 2011.
I have done a lot of reading and googling before making the leap back to that happy Christmas day, which I am about to do now. I have learned that I can easily re-install my iMac using that TM backup.
But - what happens to all the documents I have created and modified after that day? Do I have to select them one by one to restore them? Must be hundreds of them. Or is there an option to put back all the documents on my HD at the same time?
I realize that I can make another backup today using Carbon Copy Cloner which I can use to do so. Only, I don't have another external HD to make that CCC-backup.
And what happens to the applications I have installed running Lion?
So, perhaps it would be the best to erase my TM external HD, turn it into a bootable CCC HD which contains everything I have currently installed on my iMac , and restart / re-initialize the system using my SL install DVD…
Please give me some advice. I do want to downgrade, but I am scared to lose anything on the way…

Just did the downgrade, but Migration Assistant don't let you rescue any kind of information from the Time Machine backup. It just tells you to upgrade your system. I'm feelling like trying to downgrade my iPhone 3G from iOS 4 to 3. Impossible. Pretty f***** up...

Downgrading from Lion 10.7.5 to Snow Leopard 10.6 w/o Time Machine

I've been trying to solve this issue for a bit, and would appreciate any fresh perspectives on the issue.
I recently purchased a 2006 Mac Pro 1.1. It has a dual 2.66Ghz Xeon processor. I'm fairly sure nothing has been customized in the machine hardware-wise, and that it is in the original configuration apple sold it with in 2006.
The machine arrived with the Lion 10.7.5 OS on it, which was incompatible with some of the software plug-ins I use for editing audio, so I decided to re-install Snow Leopard 10.6. I inserted my install DVD like I would normally, and was greeted with the error message "OSX cannot be installed on this computer, please use version 23.1.1".
I checked out the forums, and seeing that this was a common problem (with what seemed like an easy fix), proceeded to try and install anyway. I booted from the DVD by holding "C" on start-up. After booting and asking what i wanted to use as my language, the error message "Mac OSX cannot be installed on this computer" was displayed. Thinking this was another glitch, I clicked "restore from back-up, then managed to use Disk Utility to wipe my HD and zero out the contents. I reformatted my HD to Mac OS Extended Journaled, Re-partitioned it, and then reset my NV or Pram (Command+option+P+R) until i heard the start-up noise twice.
Next, I restarted the computer, booted it from the disk again, and crossed my fingers it would let me install. No luck.
I don't have a second mac pro to clone, or a Time Machine back-up from this machine (as it is brand new to me). Furthermore, it's previous owner left me with no restore disks, or usb sticks to even put Lion back on (which i don't want to do anyway, but would at least make the machine functional until i can correctly install 10.6SL).
I do have a spare 2009 imac to work with in the meantime, with Snow Leopard, though I'm assuming attempting to clone that drive would screw with the drivers and firmware in the Mac Pro. Are there any tricks to re-install my OS without using a Time Machine back-up or clone? I have the DVD, my machine just doesn't seem to want to install from it. The nearest repair shop is several hours away.
I'm at a loss for what to try next. Any ideas?

The following will only work on a Mac that is capable of being booted by a retail Snow Leopard DVD. Fortunately, you can do the following on your model should you prefer. As an alternative you could simply create a second partition on the hard drive and install a fresh copy of Snow Leopard without having to erase the drive.
Downgrade Lion/Mountain 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.
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/Mountain Lion files.

How do I downgrade from Mavericks to Snow Leopard and save my new pages files?

Unfortunately, the Mavericks system isn't working for me. It's way too slow, has issues with Finder and so on. Basically it's just a pain in my *** and my
beloved Mac Book Unibody (2010) just can't handle it! After searching for hours online for a solution, I'd love to get back to the good old times.
I read that I can downgrade to Snow Leopard with my latest TM backup, using the recovery mode. Problem is that I "upgraded" sometime in October, so I have accumulated a bunch of new files. Being a teacher, I have tons of documents and Apple unfortunately changed all the old '09 files into '13 ones. Will they still work under the new old system, or do I have to find some way to export them into '09 files?
Is it fine to use the TM backup, or is it better to use ds store's method to recover the system?
Thanks

I backed up the system just prior to upgrading.

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.

Had upgraded to lion. Many software wouldn't work and downgraded back to snow leopard. Now it comes up c user name and password. I haven't used my password since I bought the computer years ago. I put it in but won't work. More than 8 letters, does thaMA

I upgraded to lion and many software didn't work. Downgraded back to snow leopard and now my initial login page
Is asking for my password. I put it in, but it's not working. Possible I have forgotten the correct one considering in think the last time I logged
In was when I bought the computer. But I think it's right. I did read something about if ur password was 8 characters or more it won't work? Anyone know? Or know how I can reset my password?

You would reinstall 10.6 using your installation DVD.
Out of curiosity, how much RAM do you have? Recent versions of OS X really shine with 4GB or more.

Downgrading to Mac OS X v10.6 Snow Leopard Issues

Hey there. I recently have bought a MacBook Pro with lion already on it. I wanted to play old mac games on it so I heard you could downgrade to snow leopard if you have the disk to install it. Will it work even if the lion is already installed on the computer (latest version of macbook). Also, I try to do it, since I have the disks, and it restarts my computer but doesnt start...It's just a blank grey screen that doesnt do anything. Please Help. Thanks

I repeat, you can't use any system older than the system your Mac ships with.
You can only do that if your Mac shipped with SL or earlier.

Need help with Mountain Lion downgrade to Snow Leopard

Recently upgraded to Mountain Lion, my daily applications do not work and i am losing patience, I need help downgrading to snow leopard, i have the snow leopard CDS that came with my mac
***detailed instructions help***
my mac specs
macbook pro 13" early 2011
My time machine
i have a backup with mountain lion, and i also have a backup from snow leopard,(my goal is to restore my latest backup from mountain lion to snow leopard)
i have backed up my files using time machine AND justcloud
My question is how, i do not want to lose any data, also is there any thing i need to be aware during this process

I recently downgraded from Mountain Lion back to Snow Leopard and I forgot to export my bookmarks.

Unfortunately downgrading from Mountain Lion back to Snow Leopard means I need to wipe the hard drive and install everything from scratch. That takes hours, and I've already done the bulk of the work, twice actually since I forgot to back up my photos in Iphoto and had to start over from my Time Machine backup of Mountain Lion.
Anyhow, I am curious as to whether or not there is a way to retrieve my bookmarks from the Time Machine backup and get them onto my downgraded OS, or will I have to start all over again, restore my system to Mountain Lion and go through the hours it takes to get back to Snow Leopard.

You're missing the point. If you didn't make the /username/Library/ folder visible, then it's hidden on the TM backup. Getting to ii is beyond my ken. However, Pondini's TM FAQs might have info on that madness.

Question about downgrading from Snow Leopard to Leopard

After many problems with Snow Leopard (unable to print, programs crashing, dissatisfaction with the new Preview, etc., etc.), I have decided to go back to plain old Leopard for the time being. I was perfectly happy with version 10.5.8 and had no problems whatsoever with it. I'm a freelancer and need my system to be working right. Maybe someday, I'll upgrade to Snow Leopard, but not for a while.
I plan on using Time Machine to restore my old system. The only problem is that I forgot the day I did the upgrade. I think it was either last Thursday or Friday, but I'm not sure.
Is there a way that I can see exactly when I did the upgrade so that I can be sure to restore from my latest backup?
Thanks for any advice.

You will need to boot from your Leopard installer DVD and do an Erase and Install. You cannot reliably downgrade any other way. As for restoring from TM all you really need do is post installation use Migration Assistant which will then restore your Home folder, third-party applications, support files, network preferences from your TM backup (or any other backup.) Just be sure that during the Setup Assistant you create the initial admin account using a different user (short) name than the one you normally use. Migration Assistant will restore a Home folder, but it will not overwrite nor update an existing Home folder with the same username. After you migrate the account and restart the computer, log into your old account. Verify it has admin status, change auto-login to the account, then restart to be sure all is working correctly. If so then delete the initial account created during setup.

Seems like everyday I find another program that worked on SnowLeopard, but now doesn't work on Lion. Can I easily downgrade back to Snow Leopard?

Since I installed Lion, I keep finding programs that won't run, but which ran fine on Snow Leopard. (Apple even eliminated MacSolitare.) How can I downgrade back to Snow Leopard? Do I have to erase my HD and start all over?
I have my stuff backed up on Time Machine and Carbonite.
But do those backups just contain files? Will I have to also reinstall every application that I have been using?

No they didn't, since it's not part of the OS.

Yes.

If you have a pre-Lion backup, simply restore that backup.
