I want to go back to Snow Leopard but I get "you have to install mac osx.app 23.1.1

I have a new 21.5 iMac I just purchased July 9 so I was able to download Lion for free under the up-to-date program. After installing Lion I decided I wanted to go back to Snow Leopard for various reasons. When I restart with the original Snow Leopard DVD that came with my machine and holding the C key down, I get the window for Mac OS X install DVD. I click the icon to install SL and another window pops up stating "You can't use this version of the application. Install Mac OSX.app with this version of Mac OSX. You have to install Mac OSX.app 23.1.1" To answer the question before hand....I don't have a time machine backup.

Thanks for all your help guys. I had trouble with my first install of Lion, it seemed buggy and when I tried some of the suggestions you offered, my machine did not always react the way it should have. I thought that was weird because it's a new iMac, only three weeks old. Pondini pointed me in the right direction and I think Lion is stable now. This worked after a few tries, not sure why I wasn't getting consistent results but it worked eventually.
1. Shut the computer down.
2. Hold "command" and "R" and turn on the computer (I believe this is recovery HD from the internet because it wasn't working from my hard drive)
3. After a few unsuccessful tries, and repeating #1 and #2, I finally got a window to reinstall Lion. This took about an hour to download and after that things went as expected.
As long as Lion is more stable than it was on my first install, which it seems to be now, I'll just stay with it. After this experience, I would say "make sure you need the features in Lion, and that all your current programs are compatible with Lion before you forge ahead."
Thanks again

Help.. i want to go back to snow leopard from lion

if I reinstall snow leopard and restore my latest backup from my time capsule will it leave snow leopard or will it restore lion? I don’t like how lion has slowed down my system so i want to go back to snow leopard and restore my latest files. here's what i got:

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 can't install Mac OS X Lion, I want to go back to Snow Leopard

The problem is I am stuck in the OS X Lion Install window but when I try to install it, it asks for my Apple ID, I give it but It says I haven't bought Lion. So I gave up and decided to just go back to Snow Leopard, how do I do that?

Welcome to the Apple Support Communities
Have you purchased OS X Lion? If so, check that it's not hidden in your Apple ID, so unhide it > http://support.apple.com/kb/HT4928?viewlocale=en_US&locale=en_US Finally, you will be able to reinstall Lion.
If you want to go back to Snow Leopard, your Mac should have come with DVDs or a USB drive. If your computer came with a USB drive, just insert the USB drive, hold the Option (Alt) key while your computer is starting, choose the USB drive and reinstall Snow Leopard. You may have to erase the hard drive before installing it.
If your Mac came with DVDs, you need an external optical drive or another PC or Mac to use Remote Install Mac OS X

How to revert your Mac to Snow Leopard

I just upgraded to Lion and want to go back to Snow Leopard ..I have time machine..is there a way?

I just upgraded to Lion and Quicken will not work and not sure if I want to go back to Snow Leopard. I have a timemachine and would like to know if someone could help to either get quicken working or how I can get back to snow leopard?

Did you check the Quicken website before upgrading your Mac? It specifically says that Quicken will not work on Lion.
http://quicken.intuit.com/support/help/install--register--and-convert/quicken-fo r-mac-compatibility-with-mac-osx-10-7-lion/GEN83208.html
Just reinstall Snow Leopard. Should work fine. You can downgrade to previous software as long as the Mac supports the earlier version. If it previously had Snow Leopard, then re-installing is fine.
However!!! If you have a newer computer that was "born with" Lion, you cannot downgrade, as the firmware will not be compatible.
Good Luck!

Late 2008 mbp - installed new ssd - trying to boot from snow leopard iso on flash drive - says 'cannot install mac os on this computer'

Hello -
I just installed a new M500 Crucial ssd in my late 2008 mbp - everything was working fine on old hard drive (running snow leopard) but was getting slow and wanted to upgrade - i lost my snow leopard disk when moving from hawaii so i found an iso online - using a flash drive i partitioned the disk and made the bootable image on flash drive - formatted as extended/journaled - switched out the hard drives - plugged in the flash drive - started the comp - held option - install begins to boot - choose language - all is fine - choose english - next step window pops up saying 'cannot install os on this computer' - click on utility but all options are greyed out - disk util is greyed out - only options it gives is to start from backup or restart - real confused here - all help appreciated - thanks in advance and happy new year!

Snow Leopard comes in discs only. The USB drive may be a counterfeit and/or corrupt. There are two options for you:
Get replacement original OSX installation disks from Apple customer service. Have your MBP serial number ready and there is a charge.
Or two, purchase a Snow Leopard disk from the Apple online store:

I have an IAMc 4.1 with intel core duo. Upgraded from tiger to snow leopard but cannot get safari to run in 64 bit. Is this because my older IMac won't support 64 bit?

Hi,
the Intel Core Duo processor is a 32-bit only processor and not capable of 64-bit.
Only the Core 2 Duo and later processors are capable of 64-bit.
Sorry

If I want to restore back to snow leopard

I've had it with Lion. I want to restore Leopard. I have never use the backup utilities in Leopard, but I have backed up what I need to manually to another drive. What I want to ask about is app store purchases and itunes purchases and bookmarks. After I do a full restore of Leopard, basically back to "new out of the box" iMac, I have a few questions:
1. Do I need to use the same user account when first time signing onto my iMac?
2. After all the updates are applied for Leopard, can I simple sign back into the "iMac app store" and see all my old purchases and simply reinstall them?
3. iTunes... I keep all my media files on an external USB hard drive for iTunes. Can I simply sign into iTunes with my account and "change back" the iTunes default media location in prefferences back to that external location, and have iTunes find and re apply everything just as it was before?
4. I was told there is a file "Bookmarks.plist" that I can first backup, then after the full restore back to Leopard, I can simply copy back that Bookmarks.plist file and get all my bookmarks back? I know you can do an bookmarks export from safari, but I was told backing up your Bookmarks.plist files does the same thing, only slicker and better?
5. My iCal is synced to my iPhone. Would my iPhone sync back all the events to the iCal? Can I use the iPhone to sync back info to the system?
Or do I need to first backup the iCal data somehow, also?
6. Stickies... I believe I can backup the stickeis database file, then restore it and all my stickies notes will be intacked?
7. Im also wondering about 3rd party software i've purchased, if that can be reinstalled and would the original activation or register codes or keys still work?
The same with "MS OFFICE for the iMac" and "PARALLELS", would their ownership register codes work as if I were simply reinstalling the program back onto the same old machine? Or would these 3rd party programs purchased with register codes think I was trying to install on a completely different system? Thus the original codes might not accept?
So thats my only real concerns...
Using the same user info when starting up my fully restored system for the first time?
Reinstalling already purchases iMac app-store items?
Re-installing 3rd party purchased software that will ask for the original activation or register code. WIll they still work?

Hi,
I'm having a really hard time here.
I want to update my daughters intel from Tiger to Snow Leopard for her to make her life (and mine) easier.
When I try install the OS, I keep getting an error message that OSX can't be installed on this Mac.
What's going on?
Never had so much trouble before.
Please help.

You're welcome. Please note that it is a little more difficult to obtain Snow Leopard these days. Please see the post by Kappy at the link below.

I'm selling my Macbook Pro 17" that i have upgraded to Snow Leopard but I no longer have the disks because I gave them to the person who bought my iMac. Is there a way to erase all my personal info without having to resort to wiping off the whole HD?

I no longer have the Snow leopard disks so I can't just reload the OS but I told the person I sold the MBP to that it has SL on it so I don't want to wipe it off. Is there a way to remove my personal info without resorting to reloading the software again?

Open Accounts preferences. Click on the lock icon to authenticate. Click on the Add [-] to create a new user account. Give the new account admin status. Set the account for auto-login then restart the computer. The computer should boot into the new user account. Open Accounts preferences, click on the lock icon to authenticate. Select your old account and click on the Delete [-] button. Select the third option to remove the user folder and also check the option to securely erase. If given the option to select the number of passes select one pass only. This should remove your data from any prying eyes.

Wahhh! I want to go back to Snow Leopard!

New features don't work on my MacBook. I can't get ride of the new calender event function and it defaults to one event. I need the old calender which I use to run my appointments. Lion is a threat to my business. How do I get my old operating system back?

Restore from the backups you made before upgrading.

Downgrade Lion back to Snow Leopard

I have a 3 month old macBook Pro - which came with Snow leopard (I have the original Snow Leopard install disc)
I have installed Lion but want to revert back to Snow Leopard
but Snow Laeoprd install app won't work under Lion using the DVD
as yet there is nothing on this laptop that I need - so I won't need a backup - I just want to get rid of lion & have a fresh start
When I try to boot from the Snow Leopard install disc (by holding C or option key) - I get a grey panic screen which says "You need to restart your computer. Hold down the power button until it turns off, then press the power button again"
I have done this several times - but when holding "c" I get the same message
any ideas ?

that thread assumes you can boot from the SL install DVD - there is no way my MacBook pro will do that
as I stated
When I try to boot from the Snow Leopard install disc (by holding C or option key) - I get a grey panic screen which says "You need to restart your computer. Hold down the power button until it turns off, then press the power button again"
there seems to be no way I can get into the disc to allow me to delete Lion and replace it with Snow Leopard

I want to go back to Snow Leopard but I get "you have to install mac osx.app 23.1.1
