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.

Back up your data, click here, and read the entire page. Mac OS X 10.7 and newer don't support PowerPC software such as Microsoft Office 2004; some other installed software may also be incompatible.

How do I upgrade to snow leopard from leopard if I don't have the Mac App Store?

How do I upgrade to snow leopard from leopard if I don't have the Mac App Store?

It has never been on the MAS. It's never been a download anywhere (except, maybe, as a pirated version on a torrent, which, along with being "free," will probably bring along some nice malware.) It has always been a DVD, which may be possible to obtain by calling Apple and asking for Phone Sales. Should stlll only be $29.

How to revert back to Snow Leopard from Lion?

Foolishly I just jumped straight in, downloaded Lion and installed it, and well... I really don't like it. It's not a patch on SL.
So I'm trying to work out the best way of reverting back to Snow Leopard.
I have:
My Snow Leopard install disc.
A SuperDuper, bootable backup from 48 hours pre-upgrade.
A Time Machine backup from 48 hours pre-upgrade.
I'm fairly sure that just putting the SL install disc in, isn't going to work.
I think I have a couple of options.
1. Erase the hard drive completely, and then do a fresh SL install, then restore the last TM backup.
2. Boot from the SuperDuper backup, then restore the last TM backup.
I'd prefer option 1, as this gives me a clean install (I hope).
Before I go ahead, can anyone:
a) See any problems with carrying this out, or
b) Suggest a better, safer method?
I'm a bit concerned that SL was an upgrade to an existing OS, rather than a complete OS in itself, so I'm very wary of what might happen if I wipe the drive then put the disc in, hoping it'll give me a nice new version of SL. Might need to go and do a bit more reading up.
Thanks.

For ref.
Dragged and dropped copies of important files (Docs, Pictures, Downloads, Movies etc) to a spare drive.
Printed off any docs that I absolutely could not afford to lose.
Shut down Mac.
Attached USB drive with SuperDuper backup, and powered up drive.
Powered up Mac, and immediately pressed the option key.
From the window that popped up, chose my USB drive as the boot disk and pressed return.
Mac powered up running Snow Leopard from USB drive.
Started Disk Utility, and erased the disk labelled 250.06 GB Fujitsu.... etc In the 'name' field, entered 'Macintosh HD'
Started up SuperDuper! and copied my backup over Macintosh HD.
Incidentally, the first step it took was to erase Macintosh HD anyway, so I could probably have skipped the first erase.
Let SuperDuper! do it's thing for 90 mins.
Once it had completed, closed the machine down (it wouldn't let me eject the USB drive, as presumably it was still using that as the boot disc).
Detached and powered off USB drive.
Pressed Mac power button and crossed fingers...
And goodbye annoying Lion, hello again, good old Snow Leopard!
Didn't even need to restore the last Time Machine backup.
I may take another look at Lion again, further down the road, when hopefully Apple will have realised that OS X and iOS are two completely different animals, and that we don't all want our Macs behaving like our iPads.
For now though, I'm sticking with SL.

How to install OS X Snow Leopard from OS X 10.4.11

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 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 do I revert to Snow Leopard from 10.7.4?

I have a Time Machine back-up of all my files on an external HD but, unfortunately, done AFTER installing 10.7.4 (which is a REAL BUMMER!).
If I reformat my MacBook Pro and do a clean install of 10.6.8, will it allow me to recuperate all my mail and docs backed-up in 10.7.4?
I mean, at a certain point, will it ask if I want to get my stuff from some other disk of from a Time Machine back-up?

That of course did not answer eve the begnnning of my question, since Mail in all the windoz-like "lions" is NOT compatible with Snow Leopard Mail, and a MAJOR workaround is needed.
Anyway, I solved ALL of my problems and UPGRADED TO SNOW LEOPARD, a much faster mac-like system that doesn't eat your RAM, you battery and is much less intrusive than BOTH lions, which are windoz-like, slow, eat memory and battery and...it's your falut, just like in PC H*E*L*L*...

Must return to Snow Leopard from Lion

I had a one year old iMac and the power board failed. The mac store replaced my old iMac with a new one but the new one came with Lion and all my writing files were done on an old Word program. Most of my files cannot be opened with Pages using Lion. Is there a conversion program available so I can access my old Word files or do I have to go back to Snow leopard? I had no backup so how do I go back to Snow leopard? A second question: Seeing that this problem happened due to the failure of my under warrantee iMac, a failure I did not cause, will the Apple store restore my iMac to Snow leopard for me?

Taking this stepwise, so as not to confuse you. I am not trying to insult, just to help you prioritize the actions.
First ... Your system came with SL, correct? If so, you should have gray install disks. If you have no gray install disks, call Apple, give them the serial number and they will send you duplicates for a nominal fee. Even if you have the store reinstall SL, you want them because they have "hardware test" and other software that is good to have at home.
Second ... I would ask if the files are still on your system, "most of my files cannot be opened" suggests Apple did not overwrite your data, just the system files.
Party party.
So, how to save your files (before any decision is made about going back to SL or staying with Lion)?
Buy an external self-powered disk. Preferrably already formatted Mac. USB 2.0 is slowest, but cheapest. Firewire is twice as fast, but more $$. 2x as large as your main disk. I have LaCie, and macsales.com carries many good "mac compatible" drives.
Then download CarbonCopyClone (free). Use it to clone your main disk. It is bootable, so at the very least you have a bootable alternate in case your HDD tanks. Do not worry about SL yet ... just get the backup.
That will secure your data. As to "keep Lion or go to SL", I have no valid opinion. But at least you will have the SL install disks if you decide to.
Repost when that makes sense ... trying to avoid information overload.

Boot Snow Leopard from Thumb Drive in Single User Mode on Macbook Air

I'm trying to boot from a thumb drive that I transferred the Snow Leopard .dmg on. My macbook air only lets me get into single user mode. Every time I try to boot or enter safe mode or regular mode, the Macbook Air shuts down.

I do have the installation media on my usb flash drive. I'm sure it's leopard, and the problem is that I cannot get passed the apple logo on boot. The laptop turns off after trying to finish the boot for twenty seconds. However, I can get into single user mode. I just can't seem to install the media in single user mode due to my lack of know how.

Hello, it's great you have a backup, but 10.6 should just Install 10.6 system files over the top of 10.5 system files, & leave all your data intact on the drive.
