Lion turned back to Snow Leopard by itself

I bought a copy of Lion on my iMac and it installed fine. I went and logged onto my kids' laptops (both MacBooks) and installed Lion for them using my App store account. Everything went well. However, after they rebooted their computer, the computer came back up in Snow Leopard. I went to App Store and tried to press "INSTALL" but it won't do a thing. Can anyone help pls? Thx.
Ella

OK, I look at Download folder and Application folder. I used SEARCH and cannot find 10.7.2 or Mac OS X Lion or anything like that. I bought this off the App Store on my iMac. So here are two questions:
1. I heard at Apple Store that after buying one copy of Lion on App Store, you can log in on a different computer and install Lion on multiple (5?) computers. Is that true?
2. How does one make a copy of the stuff because the installer is gone. When I press INSTALL in App Store on my kid's computer, the wheel spins around for a bit at the top and it stops. No msg, nothing shows up.
What should I do? Where should I look?

Lion Os back to Snow Leopard Os

I am looking to go back to Snow Leopard from Lion, does anyone have any suggestions were to start??

Hi...
See Kappy's post here > How do I uninstall Lion: Apple Support Communities

Transferring Data from Lion Beta back to Snow Leopard

Hey guys so when lion developer preview 4 came out i partitioned my hard drive already running snow leopard and then installed it on the new hard drive. I have been using it since it came out so have accumulated a lot of movies, songs, programs, etc. that are not on my Snow Leopard hard drive. When the final lion comes out I want to update it from the snow leopard one and erase the DP4 hard drive. Is there any way to get all the new info. from the DP4 partition to the Snow Leopard partition? I have tried migration assistant and that says i cant because the other hard drive has a new OS (Lion). So I guess i could wait until i download the final one from the app store but will migration assistant transfer all my new stuff (movies, programs, etc.)?? Thanks in advance.

Stuck in Lion installation *LIMBO* - disk damaged, disk wont repair, disk is locked, wont revert back to snow leopard

I'm stuck in Limbo. I cant complete the install and cant revert back to snow leopard. All I have are the installer utilites (including safari).
I'm running a summer 2009 release macbook pro 17 inch. I downloaded the Lion install app and proceeded to follow the instructions and guided. After less than a minute the install stopped to say that it could not be completed because the hard disk is damaged and can’t be repaired.
So...I went to disc utility to verify the disk and this is what I got.
Verifying volume “Macintosh HD”
Checking file systemPerforming live verification.
Checking Journaled HFS Plus volume.
Checking extents overflow file.
Checking catalog file.
Incorrect number of file hard links
Bad hard link creation date
(It should be 3325742596 instead of 3340504404)
Hard link record has data extents (id = 2888169)
Checking multi-linked files.
The volume Macintosh HD could not be verified completely.
Error: This disk needs to be repaired. Click Repair Disk.
So I put in my Snow Leopard disk and went to repair disk. Now, THIS is what I got.
Disk Utility can’t repair this disk. Back up as many of your files as possible, reformat the disk, and restore your backed-up files.
So then I wanted to go back to Snow Leopard at least, but I cant. When I go to “Startup Disk” and select my Mac 10.6.8 drive, it says:
You can’t change the startup disk from the selected disk.
Startup Disk could not gather enough information on Selected Disk.
So that’s annoying because it keeps me stuck in that installation "limbo" - not able to finish installing and not able to go back.
I restarted, holding down the OPTION key, but it only gave me one boot selection - the installer itself.
So then I try yet again to install this thing because there’s not much else I can do...but now it won’t even start installing...when the installer screen asks which drive I want to install it on, for which I would of course choose my Macintosh HD, it says in subscript underneath Macintosh HD:
“This disk is locked” and it wont let me select the “continue” button to begin the installation.
Please help, someone.

phew, just got everything back to "normal"
I turned off my mac for about 10 minutes and then started it up again. Also I think this time i inserted my snow leopard disc at just the right time, not too early not too late.
Whatever it was, when i went to "Startup Disk" the snow leopard disc showed up!
So then I went to disk utility after booting the snow leopard installer for the first time. It said it repaired one thing but then stopped and said it couldnt repair it and told me to back up and reformat.
Then I just ran a simple verify again and it said the HD was "OK" - it gave me a clean bill of health?!?!
So then I went to startup disk again, and was finally able to get out of limbo and back to good old snow leopard.
Now I'll install Lion, but taking all cautions beforehand...maybe i'll wait a few days first though.
Thanks to everyone.

AS I FOUND OUT LATE, LION DOES NOT SUPPORT ROSETTA, WHICH SUPPORTS QUICKEN AND CLASSIC AOL, AND MANY OTHER APPS. CAN I TAKE LION AWAY AND GO BACK TO SNOW LEOPARD?

I found out after the install of LION, that it does not support Rosetta, which runs Quicken and the classic AOL software and a myriad of other apps.
Can I go back to Snow Leopard? Is there a way to retrieve my thousands of saved E mails, which are saved on my Mac?
I still see the filing cabinet with my screen name but cannot get them to open.
Please help! Lion may roar, but the fact it does not support apps like quicken means it purrs.

I had the Apple store wiped out my hard drive and I restore my last hard drive downloard by first placing Snow leopard DVD in the DVD drive and holding "C" when turning on the machine then I follow the instructions. I am back on snow leopard and trying out two finance software to replace Quicken for mac 2007. I am trialing Quicken essentials and ibank. They are both compatable with LION. So when I am ready will download Lion again. Also, Micorsoft Office needs to be 2011 version for it to work on Lion

How to downgrade from Mountain Lion back to snow leopard with Time Machine

The final straw was the horrible mouse sideways page wiggle while trying to scroll down and read safari pages. Even after turning the feature off, tech support said it will still wiggle a little. That and the HORRIBLE grey icons everywhere was enough to send me back to my beloved iMac I loved when I bought it. I'll give up the iMessage and the few new items ML gave me. But as many others said, what I got new was far less than what was taken away.
So what tech support had me do was this. Even though the apple engineers said it would not work, apple tech support had me try it and it worked for me so good luck. Engineers said that after you install mountain Lion, it messes with ALL your time machine back ups and won't revert back to snow leopard even if you select a snow leopard date back in time. That didn't happen to me. I have a 2010 27 inch iMac
This worked for me but PROCEED AT YOU OWN RISK
Export individually any email folders or photos or data you will lose between now and the date you are reverting back to.
1. Insert Snow Leopard DVD that came with computer. The install disk not the applications. Make sure time machine external drive IS connected.
2. Restart computer and when you hear The Mac chime, hold down the C key and then it will take several minutes to boot up from the DVD.
3. Select the little blue triangle to continue in English.
4. When it gets to the screen that says "continue" stop. There might be a screen or two before this one I can't remember but either way stop at the word continue.
5. Go up to the top left and find the UTILITIES pull down menu and select disk utility.
6. In the window that opens up, Select the Apple drive which should be the very top one in the window.
7. Select erase.. it should be Mac OS extended journaled
8 select erase and maybe a password. It only takes a few seconds
9 go back up to UTILITIES in upper left and then select restore from time machine or backup or whatever it says. It's the last choice.
10. Select the external time machine drive and navigate to the date you last had Snow Leopard running and that will be the date it restores to. You will lose any data between now and then but you can export your mail, export photos, and other items separately. I only stayed on ML For a few days before hating it enough to go back so I had no loss of data except a few emails.
11. Hit RESTORE. And then it will take several hours. When you restart it, it should come right back to that day you selected as if ML was just a bad thought on someone's drawing board.   If for some reason it still comes up ML, Then they said to erase HD Again (steps 1-8) and then manually drags back USER folder or individual folders with Mail, photos etc.   if this way doesn't work, have another plan printed out so that you are not stuck by this one.
Good luck. Proceed at your own risk..

The ultimate solution:
You need an USB of at least 5 GB and the Snow Leopard Install DVD.
1. make a bootable USB with Disk Utility in it:
     a. download the Mountain Lion Installer from the App Store
     b. quit the installer after download
     c. find the installer in the Applications folder
     d. option+click in it and select "Show Pakage Contents"
     e. go to Contents>SharedSupport to find there the InstallESD.dmg file and mount it by double-clicking it
     f. with the Disk Utility, restore its contents into your USB
2. boot from the USB:
     a. restart the computer and hold-down the option key while booting
     b. select the USB and boot
3. run the Disk Utility and format in ONE partition the HD of your computer
REMEMBER: BACKUP YOUR HARD DISK BEFORE DOING ALL THESE, YOUR DISK WILL BE EREASED AND DATA BECOME UNRECOVERABLE OTHERWISE
4. insert the Snow Leopard DVD and reboot from it
5. follow the on-screen instructions to install OS X 10.6
After this, you can, if you will, upgrade to Lion or stay in Snow... Good Luck!!

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.

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

Too many Lion issues, had to restore back to Snow Leopard

I appreciate there will always be quirks with a new release. But had to roll-back to Snow Leopard due to the following issues on a new mid-2011 21.5" iMac:
- After sleep wake-up, hard-wired Ethernet loses DHCP values. I.e., no IP address. Takes about 3 minutes for it to re-acquire an IP address. Under System Preferences, Network, you can watch it acquire all the DHCP values, then 5 seconds later it loses them. Repeats. Means that after you wake up the iMac, no Ethernet, no web access. Very frustrating to wait - used to instant on.   WiFi turned off, I don't use it.
- Applications are sluggish to launch for the first time and not crisp. Get to watch the bouncing ball.
- Some applications launch, you see the menu on the Apple tool bar, but not the applicaiton's main screen. (Thunderbird 5.0.1 as an example.) If you click the application icon on the dock a second time, then it will show. Almost like the applicaiton launches minimized.
Yes, before the Lion upgrade, did the pre-upgrade checks - made sure permissions were okay, volume verified, everything cleaned up, apps up to date, Snow Leopard was up to date, etc. No hits, no runs, no errors.
Restored Snow Leopard from a Disk Utility image backup.   Everything works perfect. No ethernet issues, applicaitons are crisp, etc.
Is this an issue with Lion or hte new mid-2011 iMac hardware?
And yes, I did get the famous Apple e-mail notification that your brand new shiny iMac has the bad Seagate hard drive. Great, brand new machine, and has to be repaired.   Sigh.

Lion works fine if it's fresh installed or installed over a pristine virgin 10.6.8 system.
I bought a Macbook Air Thursday (Lion pre-installed). I bought a 27 inch iMac Friday. I installed Lion Friday. I have had to hard reboot my brand new iMac EVERY day since Friday, sometimes up to three times a day, because it just freezes once in every 3-4 videos I try to watch. Same with the Air but less frequently coz I've used it less. So Lion definitely does not work fine on a pristine virgin system.

I am ready to dump mountain lion and go back to snow leopard

Can someone stop me? I am so frustrated with lion and now mountain lion that I am actually looking at dumping the OS X 10.8 and reverting back to snow leopard.
I have a small office with three mac machines. I have been a fan of the macs for many years, even though we have software for enigineering that requires a windows versions. I have several issues that will not go away on each machine. I have a table below that describes a few of the problems. These problems have left me and my staff with no trust that our work is safe (yes, we do backups and TM). Our work flow is no longer fluid or fun with mountain lion.
Machine
OS X issues
Macbook 2009 5,0 running 10.7.3
Graphics problems, extremely slow performance opening and closing files.
Macbook Pro mid 2009, 5,1 now testing 10.8.3 beta
Graphics problems, dropped WIFI, time machine corruption, very slow finder performance, CUDA performance issues, loads of lsboxd issues, spotlite runs indexing alot, Sync services still broken in mountain lion. Cannot keep the Adobe licensing for Creative Suite 4 activated. Fresh install of 10.8.2
Macbook Pro Late 2011, running 10.8.2
Graphics problems, flash problems, kernel panics after sleep, Kernel panics with VM Ware fusion 5.0.2, Memory relase issues after software quits, Very slow finder performance, Safari causes kernel panics. Any panic causes multiple versions of Office for mac 2011 autosaved files from one original file., spotlite indexing issues. Sync services still broken in mountain lion. Fresh install of 10.8.2
I am normally a good troubleshooter and have resolved many issues so far. But they just cntiue and I am spending a lot of time resolving problems with the machine's OS that I could be using for productivity. I guess I feel like the old days as an engineer in an office where windows requires a near constant windows administrator.
Is this just me whining? Is anyone else suffering through the OS X 10.7 and 10.8 issues?
Somebady tell me I am crazy... I just want to get back to work.

I reformatted from lion back to snow leopard how do i get my music back i have it on my iphone and when i sync up i still do not have my music on my mac how do i transfer it back to my mac

i reformatted my mac pro from lion back to snow leopard how do i get my music back. i have it on my iphone and when i sync up i still do not have my music on my mac how do i transfer it back to my mac.

Wow, you didn't make a backup of your files first?
You shoudl have come here first for help before doing that.
https://discussions.apple.com/message/16276201#16276201
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

Had upgraded to lion. Many software wouldn't work and downgraded back to snow leopard. Now it comes up c user name and password. I haven't used my password since I bought the computer years ago. I put it in but won't work. More than 8 letters, does thaMA

I upgraded to lion and many software didn't work. Downgraded back to snow leopard and now my initial login page
Is asking for my password. I put it in, but it's not working. Possible I have forgotten the correct one considering in think the last time I logged
In was when I bought the computer. But I think it's right. I did read something about if ur password was 8 characters or more it won't work? Anyone know? Or know how I can reset my password?

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 backoff lion and go back to snow leopard

Too many issues with too much time for system to come up, time capsule, Adobe CS does not work, Bento files dont work, just want to go back to Snow Leopard...what are the steps?

You'll want to backup first (obviously)!!!!!!!!
But
1) boot from a Snow Leopard Disk (or your computer's original system disks if your machine came with 10.6) by EITHER holding down the OPTION key or the C key when rebooting (the compute rgoes 'bong' and then press the key immediately)
2) Choose your language
3) When you choose the disk on which to install Snow Leopard, it should yell at you (which is good).
(I don't have the images in front of my, so I apologize if the instructions aren't exact)
4) Chose ARCHIVE & INSTALL if you can.
*Archive & install, is a wonderful feature removed after Snow Leopard where you can reinstall the OS w/o overwriting the old, or reformatting the drive.
5) DO the standard install, or click 'advanced' and unselect that which you don't need (like Chinese for example, or printer drivers for brands you don't have).
6) Once the install is done, you'll want to immediately run the MAc Updater and get up to 10.6.8, the current rev of Snow Leopard.
However, should the disk not allow you to 'archive and install'; you'll need to either choose 'erase and install'; or if THAT isn't an option;
go into the menus, and to DISK UTILITY
Choose your hard drive, and erase it.
Quit Disk Utility, and repeat the above steps to install a clean version of Snow Leopard.
But please, BACK UP FIRST.
Use Super-duper or Carbon Copy Cloner (both free, both good) to clone your drive as it is presently; I am not sure if a 10.7 Time MAchine will be readible from a 10.6 migration assistant.
And next time, read before you update your OS; we've known for MONTHS that CS, CS2 won't work as they are PPC applications. CS3+ work just fine for the most part- there are some subroutines in Photoshop that evidently are still PPC applications.
I don't allow my users to upgrade to a new OS until the x.x.2 release; and in the case of Lion- I have been going over their system apps to make sure they don't use PPC apps anymore.

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?

Lion turned back to Snow Leopard by itself
