Downgrading to SL from Lion

I will tell you anybody who asks don't upgrade to lion from sl. I did this and now cannot connect at my college network anylonger. Apple can't help and IT dept at school can't help. It works everywhere else and worked fine there until I upgraded. Apple told me to reinstall SL, which I have tried but now my computer tells me it can't open my disc because a newer version of mac os x is installed. Can anybody tell me how to erase my computer and reinstall the SL op system.

You need to copy your user files off to a external storage drive first and disconnect.
To boot off the 10.6 disk you need to hold the c key down
Follow the
Restoring OS X - 10.6 "fresh install method"
https://discussions.apple.com/message/16276201#16276201
Some tips:
Do NOT restore from TimeMachine that's been connected to Lion, erase and reset it to Snow Leopard when your back on it.
For your iPhoto, you may need to right click on the iPhoto Library and "show package contents" to copy out the Originals, then import them into the new 10.6 fresh installed iPhoto.
For iTunes you may need to copy only your music out of the iTunes folder and reimporting into 10.6 iTunes, this means losing playlists.
If you assign "groupings" to your music files on iTunes Lion, it's a tag that sticks to the music files themselves, when you transfer back just the music into iTunes on 10.6 then all you have to do is create Smart Playlists based upon the grouping tag to restore your playlists.
If resintalling Snow Leopard is beyond your ability, you can find a Mac person on campus that can assist you.
Some college networks use software that hasn't been updated to work with 10.7, so they don't know what you are when you try to connect, thus they cut you off.
Your likely right you have to return to Snow Leopard until the college gets updated software, whenever that occurs.

MBP downgrade to SL from Lion without backup drive

Hi there,
I bought my 15 inch MBP only about 4 weeks ago with SL installed already on it.
Yes, I have made the mistake of upgrading to Lion and I have not made any backups at any point.
I am experiencing monitor crashes when I resume from sleep.
My MBP also did not come with a SL installation disc.
My question is simple - if I buy a copy of SL from the Apple store and install it - will it work?
Thank you.

As I answered in the other copy of this question you posted:
Purchase replacement discs from Apple: Apple Store Customer Service at 1-800-676-2775 or visit online Help for more information. To contact product and tech support visit online support site.
Purchase a copy of Snow Leopard which may work provided your computer doesn't require a special build of Snow Leopard.
However, I suspect reinstalling Lion may well fix your problem:
Reinstalling Lion Without the Installer
Boot to the Recovery HD: Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alterhatively, 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.
Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the main menu. Repair the Hard Drive and Permissions as follows.
When the recovery menu appears select Disk Utility. 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 main menu.
Reinstall Lion: Select Reinstall Lion and click on the Continue button.
Note: You can also re-download the Lion installer by opening the App Store application. Hold down the OPTION key and click on the Purchases icon in the toolbar. You should now see an active Install button to the right of your Lion purchase entry. There are situations in which this will not work. For example, if you are already booted into the Lion you originally purchased with your Apple ID or if an instance of the Lion installer is located anywhere on your computer.

How to downgrade to SL from Lion?

I have a 21.5 inch iMac that I want to re-install so I can sell it in a clean state. Unfortunately, I lost my original install discs so I called Apple Care (who don't care AT ALL) and they told me that they no longer are able to ship out replacement discs and my only option is to purchase a SL disc on the online store. I ordered a SL install DVD and once it arrived found that my iMac won't boot from this disc.
So, I called Apple tech support again and was now told that I can't do what they had suggested I do as described above because apparetnly OS X Lion makes changes to the iMac.
I am left *really* frustrated with Apple's arrogance and unwillingness to help. The agent's only response was to point me to the legal agreement for OS X Lion and he also stated "it's in there somewhere" but couldn't be more specific.
Has anyone been successful in obtaining replacement discs? if so, how?

3: Mid 2011 - Came with 10.6.6 - 10.6.7 this computer will NOT boot off the 10.6.3 retail disk
So, I called Apple tech support again and was now told that I can't do what they had suggested I do as described above because apparently OS X Lion makes changes to the iMac.
Only to the hard drive which can be entirely erased and 10.6.x placed back on as the machine came with it.
The firmware or anything else is not changed to deny booting off the 10.6 disk, provided it's the right one.
The agent's only response was to point me to the legal agreement for OS X Lion and he also stated "it's in there somewhere" but couldn't be more specific.
The legal agreement with Mac App Store software (which 10.7 is upgraded from 10.6.8 with) is your supposed to erase it when changing ownership.
Tell them you either need a notarized waiver or the 10.6.x machine specific disks or expect them to hear from your attorney.
Make sure you get their names or employee ID information, that usally gets their attention and a bump up to a smarter animal.
You can't open the iMac and replace the drive neither, like one can in a MacPro or MacBook Pro, so you need the correct disks.
You can choose to erase and install Lion, but it will be using your AppleID. Lion isn't copy protected, but the MAS software is so you can't restore that.
To boot off the 10.7+ Recovery HD partition, hold command r (or option) and reboot. Use Disk Utility to erase the OS X or second partition with the Security Option Zero to remove bad sectors. The "Zero" option is one step below the maximum 7x setting.
Use the installer with a good reliable fast Internet connection to reinstall Lion.
About the Recovery HD 10.7+ How to secure delete data from the machine
This wipe and install method is usually used as a last resort when Disk Utility is unable to see or repair the drive. Or if ownership of the machine is being passed to another.
When OS X is reinstalled using this method, upon reboot the Welcome to Mac video shows and will repeat unless a new account is created.
The problem with leaving 10.7 on the machine is if the next owner is a criminal online and the cops go to Apple for information, your AppleID is the last OS X version downloaded to the machine.

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 can I downgrade from Lion to Snow Leopard?

Hello.
Yesterday, I upgraded my Mac to Mac OS X (10.7 Lion) from 10.6.8 Snow Leopard. However, I wish to downgrade.
Obviously, I would like to not lose any data at all. However, I have never downgraded before.
I still have the Snow Leopard installation disk that came with my Mac.
How should I do this? I was thinking it would be easiest to simply head on over to an Apple Store...
I did some research (aka Googling), and I read up on the subject quite a bit.
If I simply put in the disk, will I be able to downgrade from Lion to Snow Leopard as easily as the upgrade was?
Also, I have heard about holding down the "C" button to do this... how exactly?
I have never backed up my Mac, nor used Time Machine.
Also, is it possible to install Snow Leopard on a separate disk, and set it up so that I can switch between them on command?
Will all of my preferences be saved, or does this wipe everything, not just the system and libraries folders?
I realize that I have a lot of questions, and therefore I appreciate everyone's help in advance. Thanks again.
Sincerely, Zach

Backup your files.
Booting From An OS X Installer Disc

ICal and Mail don't work after downgrade from Lion to Snow Leopard

Hey everyone, after an extremely awful time with with Lion (it knocked out of my audio interface AND my wireless) I downgraded back to Snow Leopard yesterday. I made a Carbon Copy of my Lion drive with all my data on an external drive (which I still have) and after wiping my local drive clean I reinstalled Snow Leopard from my disk. After it was done I chose to transfer data from another system local system (I selected everything) and an hour and a half later everything was transferred over. After doing a software update, I've found that I get big error messages with iCal, Mail, and even the App Store that say they can't open and I'm assuming that it has to do with incompatible data that got transferred from Lion. Any ideas on how to get those programs back up and running?? Thanks so much for you help!
Luke

Password issue when re-instaling Leopard (downgrade from Lion)

Hi there!
I'm havig a problem:
I need to downgrade from Lion to Leopard, because some of the programs i use, dont work on Lion!
But im havig a problem, after Leopard instalation (and after i erased Lion)... the instalation of Leopard runs with success, but when i have to put user name and password to LOG IN... my password doesnt work! And im sure i only have this password! HELP! Any ideas on how i could reset it some how?
Without this correct password, i need to restore (from my MAC OX 10.7 backup) my MAC to Lion again, because i just cant LOG IN!!
I've made the whole process 3 times already!!
Hope i've explained myself ok.
Thanks for your help in advance... and sorry about my english!
Benny

Well, you cannot do a clean install of Snow Leopard without going through the Setup Assistant. There is an automatic suggestion for the username - typically your first name - and a blank password field you must fill in then confirm by entering a second time. If you did not do that then you have no password. Although this will not impede the ability to log in you cannot change a blank password and you cannot install software with a blank password.
So you will need to try this:
How to change your username and/or password from the Terminal
1. Boot into single-user or verbose mode
2. At the prompt enter the following commands. Press RETURN after each:
fsck -fy
mount -uw /
launchctl load /System/Library/LaunchDaemons/com.apple.DirectoryServices.plist
dscl . -passwd /Users/username password
Replace username with the targeted user and password with the desired password.
reboot
This allows you to reset the password in single user mode without booting from the install media. The above tip is attributed to Satcomer.

Can't find iPhoto photos after downgrading to Snow Leopard from Lion

I had my photos on my External Hard Drive being used as a backup for TIme Machine.
After downgrading to Snow Leopard from Lion (my computer was running rediculusly slow likely due to being so close to the minimum requirements), I can not access any of my Time Machine dates prior to the date I downgraded. I have reinstalled Lion to try to access the files that way, but am having issues finding my old photos.
Any help would be appreciated as I've got about 15000 photos of my kids on there.

There are issues with iphoto which changes versions..
I would strongly recommend you do an archive of the TC before you do any more playing.
I presume the TC is the only place you have these photos stored??? So your entire library is hard disk erase from total annilahation.. not good!!
Load a real utility into Lion.. archive is not present on the new version.. why apple why??
http://support.apple.com/kb/DL1482
You can then do a full restore to an external drive.. or something fancy..
Pondini is the saviour here.
http://pondini.org/TM/15.html
There is a specific section on iphoto and its pain.
I strongly suggest you read the entire section from Q14-18 so you actually understand what TM does.

Can I downgrade mail from Lion Mail(v.5) to Snow Leopard Mail(v.4)?

I just bought a new MacBook (13.3" running Lion OS 10.7.1). I -really- don't like the new format of mail and have problems with searching and other organization methods I worked out. I would like to downgrade from Lion Mail (v.5) to Snow Leopard Mail (v.4). I understand that some people have downgraded the whole operating system and saw those instructions in the discussion forums, but I would like to -only- downgrade mail. Any ideas?
Also, any recommendations on reducing my load times and delays in mail? I have over 100,000 emails over the past 4 years that are bogging down the system. I have tried archiving some older messages, but the system freezes and then downloads all the attachments from my oldest messages, filling up the entire hard disk. Thanks in advance!

There is a long thread about this -- https://discussions.apple.com/message/15733107#15733107 -- and the bottom line is that it is possible to install and run SL on a 2011 mini (with some rather wonky hacking...) BUT it doesn't work very well. Performance benchmarks of the same machine in SL and Lion show the SL as definitely slower.
Plus people are having problems with certain features on the machine not working.
I think that your performance issues sound like something else is wrong... The 2GB is a definite problem -- do you know that you can buy 8GB for the machine for $60, and getting it installed is a snap? But the first thing that I would do is to install applejack and boot into single-user mode and run disk repair (aka fsck.) Another question -- if you look on your console, do you see a voracious cpu-eating process called mds? It's the indexer for Spotlight, and there is nothing to be done about it than to just wait it out, and your machine will work much better when it is done. And Spotlight is not just a SL problem -- if you install SL it's going to want to index your disk, too...

Downgrading from Lion to 10.6.8?

Is it possible to downgrade after installing Lion back to 10.6.8? As of last night I installed Lion onto my MBP 2.4GHz Intel Core 2 Duo (mid-2007) and my laptops performance has basically gone to **** due to Lion trying to use up all my active memory and I'd much rather go back to Snow Leopard where everything ran smoothly and I didn't have to deal with Lion's sluggish performance.

Back to Snow Leopard from Lion install method
Read and print out these instructions, your computer is going to be offline and you wil be cutoff from help until your machine is restored.
Clear the Desktop, Downloads and Trash of anything you wish to keep by placing their files in the respective Documents, Music, Pictures, Movie folders.
If you have a TimeMachine drive, update it and disconnect for the duration of this restore time. It will be your second backup system and will have to be wiped and setup again after successfully going back to Snow Leopard if it was connected to the OS X 10.7 boot drive. If it wasn't, then leave it disconnected without updating to Lion.
Backup ALL your Users folders (Documents, Pictures, Movies, Music etc) manually (drag and drop methods) to a (not TimeMachine) external powered drive (HFS+ journaled formatted in Disk Utility) and disconnect, your going to be wiping the entire disk of ALL DATA. (warning, everything will be gone and not recovered)
Here we go!
Hold c and boot off the 10.6 installer disk that comes with your computer and second screen in just STOP.
Look at the Utilities Menu for Disk Utility.
On the left is the name of your hard drive maker, click it and Erase (format HFS+ Journaled), give it the same name as before, and click Erase...
This should wipe the drive of ALL partitions (GUID, OS X and 10.7 Recovery, Windows if present)
When it's done, quit and install OS X 10.6. Then install all your programs from fresh sources and validate/update.
When you setup a first account, use the same user name as before, this way you can simply drag and drop the content of your previous Users folders from the external drive right back into the new Users folders and everything should work peachy. Links in iTunes to music, playlists and iPhoto links especially.
Update OS X to 10.6.8 using the Combo Update for best results.
http://support.apple.com/kb/DL1399
(Note: If your original machine had 10.5 and you want the free iLife that comes with the disks with the computer, then you'll have to install 10.5 first using the same c boot/erase/format methods as above, then update to 10.6 via the disk, then Combo Update 10.6.8)
Final step optional but highly receommended.
A lot of people use a Carbon Copy Clone of their boot drive to a HFS+Journaled external drive as a "hold the option key" bootable backup in case something goes wrong with their boot drive or need to restore to a previous OS X version.. (in addition to TimeMachine drive for more immediate backups.)
It's not advised to have a Bootable Clone and a TimeMachine partition on the same external drive, as two drives gives hardware protection in case one fails.

Downgrading from Lion w/o having SL Installation DVD?

After two month of using Lion I am so disappointed that I would like to downgrade to Snow Leopard. I bought a new iMAC in Oct 2011 with Lion pre-installed. I know that the mid 2011 iMac model has been delivered with Snow Leopard before Lion was released and published.
I do not have any SL Installation DVD. Can I buy just a standard Snow Leopard DVD set or do I have to find someone which has the original SL Installation DVD delivered with the mid 2011 iMac model before Lion was released.
Would be great if someone can provide help. Thanks.

You will have to purchase a retail Snow Leopard DVD that installs a version of OS X later than the version that was originally installed from the factory. According to my information that was 10.6.6. If you cannot find a Snow Leopard DVD that installs 10.6.6 or later then you will have to order replacement discs from Apple. I suggest you do that anyway because those discs also have the installers for all the pre-bundled software that came with the computer along with the Apple Hardware Test. None of that will be on the retail DVD.

How do I downgrade from Lion to Snow Leopard without losing iWork 09? I upgraded my MBP from 10.5 (originally 10.4) to 10.6, then again to 10.7. Should I go back to 10.4, 10.5 or just to 10.6?

Thanks for the information! My sister gave me the MBP for my daughter with Leopard installed. I purchased Snow Leopard and installed it, then my daughter purchased Lion. So I do have all the installers. If iWork wasn't included with any of those, I guess my sister purchased it while running Leopard. I'll have to contact her. Thanks again.

How can I go back to Snow Leopard from lion without loosing files, etc.?

I recently downloaded Mac OS X Lion, but I can't stand it. I've heard you can't get a refund from the app store but I'm not sure how that works and I'd realy like my money back. Also, if I do downgrade, I'm not sure how to back up my files. I have music, documents, and pictures I don't want to lose. I don't have time machine. I have a usb but I'm not sure if it is capable of holding music from itunes? Other than that I'm not sure how else to back up things. I realize I have a lot of questions and I'm not exactly well informed with this stuff so any help would be greatly appreciated (:

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.
