How to move back to Snow Leopard

I have a MacBook and migrated to OS X 10.7.4 from previous Snow Leopard.
My operating system now is very slow. How do I revert back to Snow Leopard?

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.

How do I move back to Snow Leopard from Lion if Lion came on the computer?

I have a 27" iMac that came with Lion on it. I want to go back to Snow Leopard so that some of the old software that I liked can be used again. I do not use apps, do not have an iphone or ipad, would never put information in to a Cloud, so Lion aor Mountain Lion are not for me. Is there a way to go back to Snow Leopard and still have the ability to upgrade should I change my mind?

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 Do I Back Up Snow Leopard?

Hi,
I have a Macbook Pro its literally 18 months old. I also have a little portable hard drive, how do I back up my whole macbook including snow leopard itself.
Can this be done through time machine?
If I was to back up the mac with time machine and then wanted to reinstall the whole system can I do this from the back up?
Cheers,
C x

How 'little' an external? For a normal bootable backup it would need to be rather more than the currently used capacity of your MBP HD, and preferably as big or bigger than the MBP HD itself.
To produce a bootable clone of your MBP you can use a number of third-party applications;
CarbonCopyCloner
SuperDuper
SilverKeeper
to name but three. You'll need to ensure the external is partitioned with GUID partition map and Mac OS Extended (journalled) file system.
With a bootable clone you can boot from the external and if necessary restore the original system by cloning back to Macintosh HD.
Time machine is better suited for a drive that can be permanently connected to allow hourly backups, and the drive should ideally be at least 1.5 times the size of the Macintosh HD.
You can restore a system from Time Machine, but you can't boot from a TM drive.

How do I go from Mavericks back to Snow Leopard

I updated my late 2009 MacBook Pro to Mavericks as I thought the system efficiency upgrades the new OS tauted would be good, but alas my computer is super slow for ALL functions. I won't give details, because now after the fact, I'm learning others have had this problems. I don't have time to hope it will improve, I want to go straight back to Snow Leopard and will wait for Mavericks to have more updates, improvements and better reviews on speed.
Technical question on how to go back/ reinstall Snow Leopard?
First my stats:
I have 2 partitions on my MacBook Pro: 1. my usual use 400gb partition, which was on snow leopard and went up to Mavericks, and 2. 100gb "test" partition running 10.6.8.
I have an external backup hard drive with Time Machine backup of the 400GB partition.
There was an apple support article - http://support.apple.com/kb/PH14176 - that said to revert to previous OS you simply:
Choose Apple menu > Restart. Once your Mac restarts (and the gray screen appears), hold down the Command (⌘) and R keys.
Select “Restore from a Time Machine Backup,” then click Continue.
Is this indeed going to work for me? Or will it delete the 2 partitions?
Or do I pull out the Snow Leopard install disc and launch Disk Utility and erase the partition drive and install snow leopard that way?
Would like some confirmation on the best way to go before proceeding, but hoping to tackle this right away.
Thanks!

Here is teh entrecheck report. Can you advise on any issues or items that defeinitely and easily can be addressed? Is there anything here that could be causing the tremendously slow, nearly not function computer with Mavericks (I feel like I'm back in the days of OS9), which was FINE on Snow Leopard?

One other issue that concerns me. I launched Activity Monitor because the computer was so slow and it shows the "memory used: 3.99GB" out of "Physical Memory: 4:00GB" seems like it is being used up (though Entrcheck may be giving different information), which doesn't make sense as I wasn't running too many, and not energy/memory hogging programs (i.e. just Mail, Contact, Safari, & OverDrive).
Any thoughts on this?

How do I remove Lion and go back to Snow Leopard OS?

How do I remove Lion and go back to Snow Leopard?

If you have the white upgrade disk (originally, you had Leopard and bought SL later), easy. I'm not sure if you have the grey disks (you bought the machine with SL).
If you have the white disk, the first thing you do is get a USB external HD. Format it to GUID with disk utility.
Insert the white SL disk and restart. Follow the instructions to install SL on the external disk.
Have a look here for a step by step tutorial for setting up the external HD: http://www.maciverse.com/installing-snow-leopard-onto-an-external-hard-drive.htm l
From here on in you have two choices:
1. You can run SL off the external disk and keep Lion and all your files/data on the internal disk.
This is the easiset thing to do. You can open files from your Internal Lion disk by navigating through to it in Finder when you're booted in to SL on your external disk. Practical if you have a desktop machine, maybe not if you have a laptop that you need to carry everywhere (you'd have carry the external HD with you all the time).
Any non-Lion only (i.e., not Safari, Preview, Terminal and Mail Lion upgrades) apps should also run off your Lion disk when you're booted into SL, but if you have any problems, just drag them from the Lion Apps folder to the SL apps folder.
2. Move everything over to the external disk if you plan to install SL back to your internal disk.
Start copying over all your apps and files manually by dragging them from the internal disk Apps and Folders to the external disk Apps and Folders. If you have Time Machine, you can also copy your files by navigating to Time Machine through the Finder rather than trying to use the Time machine interface.
You might spend some days doing this, but it's worth doing it manually. When you're done and sure you have everything, google 'Carbon Copy Cloner'. Download it (its free), and clone your external HD to your internal HD. SL restored!

Back to Snow Leopard -- how?

Having worked with OS X Lion now for about a day, I have to say I'm encountering too many issues. (A selection: Safari won't allow me to start with my Homepage and then have new tabs open with the Same Page for some reason (I'm not sure what exactly the people who review the software are reviewing: don't they see this?); my scanner won't scan to the right destination anymore; the folders in the Finder's sidebar that I've added there myself all have generic icons, which makes it hard for me to find the different folders I have there; apps that have to start up when other apps export files to them, don't -- et cetera. Just really a lot of stuff.) Maybe some of the issues can be fixed, but even then I can't see the appeal of Lion. A thumbs down, I'm afraid to say.
What I'd like to know is: how do I revert back to Snow Leopard as painlessly as possible? I have my stuff backed up, I have Snow Leopard's Install disc right here, I'm all set. What do I do? I want everything to be the way it was yesterday. Maybe I'll look at Lion again later, but not right now.

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.
Disconnect other drives except the sole backup drive.
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 boot disk of ALL DATA.
(warning, everything will be gone and not recovered, OS, programs, files, Windows etc all gone.)
Note: You might want to hold c and boot off the 10.6 installer disk and use Disk Utility to format the new blank external drive instead of using OS X Lion if that's hosed. Then reboot into Lion and copy files, may be safer that way.
Here we go!
Hold c and boot off the 10.6 installer disk that comes with your computer and second screen in just STOP there, don't install OS X yet.
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 drive name as before, and click Erase...
(note: if you want to "scrub" the drive of old files that haven't been overwritten yet, then use the Security Option > Zero Erase, takes a lot longer)
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 recommended.
A lot of people use a Carbon Copy Clone of their boot drive to a new HFS+Journaled external drive (used only for this purpose) 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.

How do you switch back to snow leopard, lion is crap?

How do tou switch back to snow leopard? Lion is crap, so dissapointed.

Keep the inflamatory comments down or the thread will disappear, as long as your questions are supported related it's fine.
Here's how to go back to Snow.
How can I uninstall OS X Lion and go back to Snow Leopard?
1: Copy your user file folders (Documents, Pictures, Movies, Music, not Library) to a external blank Disk Utility formatted HFS drive (not TimeMachine) and disconnect all drives. Make a note of your username and hard drive name. Write down any essential information like passwords stored in keychains and product serial keys.
2: Stick the 10.6 installer disk into the machine and reboot holding the c key down. Second screen in choose Disk Utility from the Utilities menu.
3: On the left select the hard drive makers name of your internal boot drive (important) then click Erase and Erase... button (if you want to wipe the drive of all lingering data then choose Security Option>Zero all data) when choosing a name for the drive, use the same drive name as before.
4: Quit and install 10.6, then go through setup, reboot and use the same user name as before. Software Update, install programs from fresh sources (enter any serial keys) Hold Option and click on Purchases in AppStore to redownload (not Lion of course) and then finally return user files to their respective folders on the Snow Leopard drive.
5: If you have issues with iPhoto, you can right click on the iPhoto Library and "Show Package contents" and in there is a folder with all your originals. Copy them out and delete the iPhoto Library and reboot, restart iPhoto and it should be recreated, which you can then import your copied originals again.
Note: using the same drive and user name as before, returning files exactly into their respective Music, Documents and Pictures folders like before matches any pathnames some files like iTunes has to the location of your files. If not done, then exclamation points will occur in iTunes when you click on a song. The iTunes Library will have to be opened in Text Edit and all the partial pathnames "find and replace" corrected to repair.
Optional, but recommended.
Ideally it's best to first Carbon Copy Cloner the 10.7 internal to another blank external HFS drive before doing the above steps 1-5 as that way you have a copy of everything in case you missed something or you need to hold option boot from the 10.7 clone. The clone can later be erased and used as a 10.6 clone. Or reversed cloned back onto the internal drive or as many external drives as needed. (don't boot a clone on a different Mac, you can access the files though)
Clones are hold option key bootable, TimeMachines drives are not.
Note: The above steps are ONLY for Mac's that didn't come with Lion preinstalled. For reverting a factory Lion to Snow Leopard requires other methods.

I was experimenting with the Snow Leopard Server DVD on my MacBook Pro running Snow Leopard. I started the installation process, expecting that it would not install on the Startup Disk, as I had not booted from the DVD.
To my surprise it installed!
How do I "uninstall" or revert back to Snow Leopard, without have to take such drastic steps that I would lose all of my Snow Leopard System folder contents (such as doing a wipe and starting over with a fresh Snow Leopard install)? Thank you.

I assume by "back up your data" you mean a Time Machine backup?
Preferably, yes.
I have a BootCamp partition to run Windows; does Time Machine back that up, too?
No, but it won't be affected unless something goes wrong. You still need to back it up, of course, just like all other data.

Wow, you didn't make a backup of your files first?
You shoudl have come here first for help before doing that.

All I can say is make sure you have the same account name on the computer like before, even if you have to create a new user under System Preferences>accounts, then log into your itunes account with that and try to reverse sync from the iPhone like you would normally.
Apple doesn't expect one to go backwards, so they are not all that friendly, you may have to ask around on MacRumors for third party software that can reverse sync from iOS devices.
Good luck

My laptop hard drive crashed, used to have lion now it is back to snow leopard. how do i get it back to lion again?

my laptop hard drive crashed, used to have lion now it is back to snow leopard. i lost all of my info, music, pictures, etc. how do i get it back to lion again? this is very frustrating because i paid $30 to download it and now i am unable to have it again.

If your Mac is off then start up. As soon as you hear the boot chime, hold down the Option key until the Mac and Windows Disks show up. Then click on the Mac disk and the arrow below it. After it boots up in Mac then go to System Preferences>Startup Disk and select your Mac partition as the Startup disk.
If you are in Windows then look for the Boot Camp icon on the taskbar. It will look like a gray box sitting on one corner. One of the options when you click it is to restart in Mac OS. After it boots up in Mac then go to System Preferences>Startup Disk and select your Mac partition as the Startup disk.

How do I disable Lion and go back to snow leopard

I up graded to Lion. Now my wireless router can't connect because it doesn't support Lion. I don't want to have to buy a new router.
Can I disable lion and go back to snow leopard?
P.S. I am new at computers so be easy on the terminology please.

It would help if you gave some information on WHY the router isn't working. Start with the basics:
-What brand and model is the router? If you can get a version number, that is also sometimes helpful. This info is generally printed somewhere on the router, usually a label on the back or bottom.
-What do you mean by "doesn't support" - did you get this info from the manufacturer, or is this based on you not being able to connect? Routers use standard wireless protocols (called 802.11a/b, g, or n). The network cards in Mac computers also use these same protocols.I can't think of a reason why it shouldn't work.
-Does your router have a wired connection? If so, can you connect with an Ethernet cable? You may need to be able to connect to the router directly to change settings.
-How old is your router? And have you ever tried to upgrade the firmware settings on it?
-Can you connect to ANY wireless routers anywhere else with your Lion computer?
-Do you have any OTHER computers (Windows or Mac) that can successfully connect to your wireless router?

How can I unistall Lion and go back to Snow Leopard?

I upgraded to Lion (stupidly and blindly) and now most of my programs are not compatible. What is the process to go back to Snow Leopard?

Given the lack of response to this particular discussion, and given all the various and sundry ideas on this topic, I have had a panic-stricken 48 or so hours since I asked my question. Here's what finally worked to get me back to normal:
1. First, I gritted my teeth and erased my hard drive, hoping and praying I'd be able to restore from Time Machine. I'd been backing up for quite some time, but never needed it before. HOWEVER:
Lion evidently left little gremlins all over my hard drive, because I simply could not get my hard drive restored properly, not from the Time Machine restore function on the SL disk NOR from a manual "Star Wars" pick and choose with my Time Machine. Therefore (and this is important):
I zeroed out my hard drive completely, after trying for an entire day to get things back to normal. What you have to do is start up from the Snow Leopard disk, and do a COMPLETE erase, by which I mean that when you use DU to erase your hard drive, you go into the "security" panel on th DU screen and do a 7-pass zero-initialization of your hard drive, i.e., write zeros all over everything on your hard drive seven times, leaving it truly free of that yucky Lion. THEN I reinstalled Snow Leopard, ran Software Update several times until it had updated everything it wanted to ad nauseum, and THEN was able to get Time Machine to work properly and bit by bit restored everything I wanted to restore. I am appalled at the lack of accurate documentation that comes with Time Machine, frankly. Anyway, when you get ready to restore your software AFTER you put the Snow Leopard system back on your hard drive and update it, you have to go back to a backup from BEFORE you installed Lion, though: this is important. Don't try to put anything associated with Lion back on your hard drive. For me, that backup was done was last Friday. It took ages, but....my hard drive is now purring like a kitten, and I have Snow Leopard and all my old software back. It was a mess, but it seems to be over. I learned from this disaster how important it is to completely wipe your hard drive clean before trying to reinstall an older operating system. As far as Lion goes, I will be extremely careful before I assume any new upgrade is a good upgrade. It isn't. I LIKE my elderly Adobe programs and my kid likes her games that need Rosetta, as does Word 2004. My Mac is much happier with Snow Leopard. For now. If it ain't broke, don't fix it.

How do I remove Lion and go back to Snow Leopard?

I spent half a day downloading and installing Lion today.
All my Microsoft Office applications are now unusable. This is unacceptable!!! It is more important to be functional with my apps than to have a fancy new OS that doesn't allow me to work!!!
So, please, how do I uninstall/remove and go back to Snow Leopard?
