IMac i7 need to install snow leopard NOT Lion - Will it allow the install of 10.6?

I have a bit of a quirk to deal with, a client has a Snow Leopard Network but just recently had a replacement iMac i7 delivered for a previous box from earlier in the year. The IT Contractor is stating that the machine can only take Lion and will not install Snow Leopard. The problem is there is some FileMaker issues that have come up with some deep level custom functions that have exposed a critical problem and the machine needs to run Snow Leopard. This would be until the work around is developed for the software solution or FMI comes out with the next version of FileMaker resolving the issue.
Is the IT Contract full of it ? If not is there a way to force the iMac i7 to accept a Snow Leopard installation ?

For years Macs have not be able to run earlier versions of OS X than they originally shipped with so this is nothing new. It also makes a lot of sense when you think of it, one of the reasons Mac's run so well is the software and hardware are optimized to run well together. Attempting to install an earlier version of OS X than what the machine was designed for is technically possible but it also comes with significant risks because you're then dealing with a system that wasn't designed to run well together...in other words you're emulating the MS Windows world. While there can be some temporary inconvenience as you're experiencing in this case Apple makes these decisions for a reason. While not always obvious to we end users but there are good reasons none the less.

I accidentally downloaded lion. I did a timemachine back-up and tried to reload snow leopard. It will not accept. How do I re-install snow leopard over lion?

I accidently installed lion on my mac book pro. I did a time machine back-up. When i try to re-install snow leopard, it won't take. Any suggestions on how to install snow leopard over lion?

Accidentally, eh? How, might I ask?
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.

You need to *call* Apple at 1-800-MY-APPLE, as Ralph already said.
But "since one week" sounds like a direct translation of French "il y a". You should call your local country's Apple suuport and ask.

Do I need to download Snow Leopard or Lion again?

I emptied my trash after downloading Lion and now my computer is slow. My computer tried to warn me when a screen came up a few times asking if I really wanted to delete (a) certain file(s) because in doing so it could affect other programs. I kept clicking continue because the files had been in the trash and I haven't missed them for the day since I downloaded Lion. Now I find I have to double-click on some programs to open them or some icons don't work at all. When will I learn? What do I do now?

Can I install Snow Leopard over Lion to install old software after hard drive crashed?

My hard drive crashed and I lost everything. I have a new hard drive, but when the repair shop installed my operating system, they installed Lion and I no longer have my prior updates. My computer had been updated a few times. I have a lot of software that only can be installed up to 10.7 such as Adobe Photoshop Elements 10, Office Mac 2011, etc. I was wondering if I installed Snow Leopard over Lion, would I lose Lion? Should I install Snow Leopard and then Lion again? I don't want to damage my like new computer and I don't want to have to go out and buy all new software. Is there a solution? Thanks in advance!

Sounds complicated! If I repartition the drive and install Snow Leopard onto the blank volume, will Lion still be there? Or, will the computer basically have two operating systems that I have to go back and forth from. Is this something a novice like myself can do?

My 2006 iMac running Snow Leopard won't boot even after erasing and re-installing Snow Leopard (via my MacBookPro), either from the HD or DVD drive. Can't get it to run Hardware Test. Disk Utility says disk OK - files are there. What can I do?

My 2006 iMac running Snow Leopard won't boot even after erasing and re-installing Snow Leopard. I erased and re-installed by putting the iMac in Target Disk mode and usin my MacBookPro as the host. But after numerous attempts I still can't get it to boot either from the HD or DVD drive. I just get the white screen after the wheel stops spinning. I can't get it to run Hardware Test - just get the white screen. If I use Disk Utility via my MBP it says the disk appears OK. All the Snow Leopad files appear to have been installed. What can I do?

Perhaps you installed the wrong version OS X onto the iMac, you can't use the disk from another Mac.
clean the disk.
If it's not working then use this method to create a bootable 10.6 USB from the iMac machine specific 10.6 disk or the 10.6.3 retail disk on your other Mac, use it to boot the iMac with.

How to erase and install Snow Leopard 10.6

Unable to install Snow Leopard "Not Interchangeable"

I have attempted to install Snow Leopard twice so far, both times unsuccessful.
What is happening is it installs for about 10-15 mins and then wants to restart the the computer. fine. Once it comes back up, it has me select a language, then it searches for a disk to install the new program... Once it finally recognizes my Hard Drive (after about 10 more mins) I can select my hard drive and click "install". it them immediately tells me that the disk(Snow Leopard) is not "Interchangeable (or maybe 'Not Changeable')". I am not too sure what that means... If anyone has had the same issue, please advise.
Thanks, Ryan

EDIT: I have tried it again, and it seems like the initial install crashes and restarts my computer. Once it restarts, it acts like it wants to start the install again, and it is not allowed.

How to partition to install Snow Leopard and Lion on one computer

My first posting:
My iMac came with Leopard. I upgraded to Lion, 3 months ago. I found out that Appleworks doesn't work anymore... very displeased because I always used Mac Strong points (for the past 30 years), which is drawing, like McDraw, McDraw 11, Clarisworks, Appleworks, etc. Apple could have have included a software in iworks to open the numerous works I have done over the years in drawing. Now iDVD doesn't come with Lion anymore. Another blow from Apple!! And iDVD 7.1.2 (after upgrade from Leopard's iDVD) doesn't work too well in Lion... quite a few things are wrong.
Consequently, I want to install Leopard in an external HD, where I could use Appleworks and iDVD.
I have a 1 tera WD Firewire as an external HD. I have tried a few ways to install Leopard on my external HD with no succes.
I have tried "partionning" the external HD, but when it came to "Scan disc image" of Leopard, I had the message: Unable to scan "Install" (Resource busy)
I have tried to install with original Leopard DVD, but after pushing restart (to chose my external HD), then my computer keeps asking me to push restart.
Can anymore can tell me how to properly install Leopard on my external HD?
MartinR says:
Connect your WD Firewire drive. Open Disk Utility and check to make sure that it is partitioned as GUID partition scheme (assuming you have an Intel iMac) and is formatted as Mac OS Extended (Journaled). If not, you will need to repartition and reformat the drive - note that this will erase everything that is on the drive.
Notes:
-If you have an Intel Mac you cannot install OS X to a drive that is partitioned as Apple Partition Map; it must be GUID Partition Scheme.
-Mac OS Extended (Journaled) is the same as the "HFS+" as previously mentioned.
-For the disk to be bootable it must be formatted as Mac OS Extended (Journaled) not plain Mac OS Extended.
Next, insert your Leopard install DVD in your iMac. If the installer opens, just exit/close the installer window. Do not remove the Leopard install DVD from the drive.
Shut down your Mac. Then restart it by holding down the "C" key while it starts. This will make your iMac start from the Leopard install disk that is in the CD/DVD drive. You should then be able to select your external WD drive and install Leopard there.
My response to MartinR (I appreciate the dedication of the helpers)
I tried MartinR solution but it doesn't work. When I restart and keep "C" depressed, after a while, a kind of gray drape closes the screen and tells me I have to restart my computer par pressing "restart" for a few seconds. Then when the computer reboots, it tells me there was a problem and had to restart the computer with a report to Apple window.
I wonder if my computer is not defective? In 30 years, this is the only Apple computer that broke down on me (Always been faitful to Apple computers in spite of the fact they had little apps then), and twice on top of that. The first repair was done by Apple in Wellington Mall, Florida (hard drive had to be replaced); the second time was Northstar Computer in Sudbury, Ontario (optical drive had to replaced). Maybe that tells us something? Were replacement parts up to par? My computer seems to be working OK. I verified my HD with Disk Utility, and everything was OK.
My computer is an Intel Core 2 Duo, 3.06 GHz and 4 GB of ram.
My WD external drive is formatted as GUID Partition Table, and Mac OS Extended (Journaled).

Since installing Snow Leopard and Lion two weeks ago, my iTunes program opens seemingly at will. It usually starts playing music, too. What is causing this?

Since installing Snow Leopard and then Lion on my Intel-based iMac two weeks ago, my iTunes program seems to open at will whenever the computer is on. It often begins playing music, as well. What is causing this and how do I make it stop?

There are ways to minimize, mitigate, and help avoid a lot of problems.
Bootable backups.
Zeroing a drive twice before using, and format it with SL DVD Apple Disk Utility for sure.
Even a clean install should import old apps without having to reauthorize.
If you must do an upgrade, do it from the SL DVD, after repairing the drive and be sure to use the SL version of Alsoft Disk Warrior (4.2).
Wait six months before jumping on a new OS.
10% is still too many. Yes, it is more sensitive to RAM and hard drive errors, doesn't like some controllers; most ext hdd cases; and enough software to make for test-only status. And it only IDs some known incompatible applications, drivers, extensions, etc and does not remove even those always in best manner.
Plus, there are problems with the new Rosetta and the cache files it now uses. So some apps and plug-ins will cause more trouble. Not all are ready. Good reason to hold off for the months it takes.
Other devices act different as far as on/off behavior.
(Migrating from G5s to Mac Pro can cause all kinds of problems, weird behavior, sluggish system, and why anyone that went down that road was strongly recommended to NOT use Migration Assistant for any of their applications, and to ONLY do clean/fresh installs of any apps. If you skipped that day, didn't read the Guide to M.A., or didn't want to do fresh installs then, your system could have been on borrowed time. If you did do clean install of applications, great.
Installing SL can result in a corrupt directory - I think and it "seems" to be happening, but no real proof, just gut feeling and instinct (underlying file system problem? weak sectors that pre-existed waiting to happen?).
Remember all the "there just aren't a lot of 64-bit drivers" for Vista and XP? it's come home to roost.
... my guess is not enough incense and offerings. To hop into TimeMachine and SuperDuper backup images and pull the 1TB for another day (week, month, year).

Installing snow leopard over lion

I just bought a MBP two days ago with Lion preinstalled and i want to install snow leopard.
i have the retail dvd of SL but after it starts booting from DVD it appears the "You need to restart your computer. Hold Down the Power button for several seconds or press the Restart button"
http://img149.imageshack.us/img149/7792/pict0017lo8.jpg
the dvd works ok in another older MBP 2008.
how can i install SL?

Two things,
First Mac's can't c or option boot off install disks that the OS isnt' designed for it or doesn't have the hardware drivers required on the disk.
Second the grey disks are machine model specific, meaning you can only use them with another exact model machiine.
Thrid Apple restricts booting off of earlier OS X install disks in the firmware, but if the OS gets on the drive and it works for the hardware, it will run. But not well on all machines, but yours is likely going to be fine.
So you want to get 10.6 on a factory 10.7 Mac, it's possible if Apple hasn't done any changes lately, your likely going to need another Mac that can boot off the 10.6.3 disks and apply the 10.6.8 combo update together so the drivers are together, then imaged to a wiped hard drive or partition using Firewire Target Disk Mode and another Mac.
"The Proceedure" is here and there are links to discussions and updates all over the web.
https://discussions.apple.com/thread/3264421?start=0&tstart=0
You also may need to read my post about restoring Lion before you erase the disk, you need to copy the Lion Recovery Partiton first with the Lion Disk Assistant. Cloning will also help a LOT.

Trying to re-install Snow Leopard over Lion and Macbook Pro is beeping like a memory failure

I installed Lion on my work 15" MacBook Pro i7 to give it a go, and it's not working with the system we use for Active Directory login, so I need to roll back to Snow Leopard.
I don't have a Time Machine backup, but I have pulled all the data I need from the machine, and have wiped the hard disk ready to reinstall Snow Leopard.
I have a retail copy of Snow Leopard that I've recently used successfully for fresh installs on other machines, but now once I insert the DVD into this machine that's had Lion on it, it's not responding and just making alarming BEEP BEEP BEEP noises.
I googled that and it might be bad RAM (possible, but unlikely? the machine has been running very well up until now)
I've wiped the PRAM, but the instructions for wiping the SMC are a bit cryptic for these machines ...
Does anyone have any clues as to what might be causing this? A firmware issue of some sort?
Maybe the hidden EFI partition on the drive won't let you install Snow Leopard over a disk that's had Lion?

Might be some useful info here:

" I used target disk mode to install Snow Leopard on its partition. I used a friends Macbook Pro, but I put my machine into target disk mode and ran the installer from his user account and optical drive. From a couple things I read online, it seems that Apple recommends putting the other machine in target disk mode and doing it the other way around. I guess some critical files might not have been installed? I also used a retail copy of Snow Leopard instead of my grey recovery disk, so that might be it too. "
"Your machine is newer than the retail copy of Snow Leopard. Use the restore disks it came with.
The installation will need to be done from your machine. You may need to do a net install, so look at "Remote Install Mac OS X" in Utilities."
I'm currently installing from the macbook firewired to the other machine as recommended so hopefully that might help
