Reports have been cropping up on the Apple Support forums that users have been losing all their data due to a nasty bug in Snow Leopard, Apple's latest Operating System. Many users are reporting that all settings are being reset and most data is gone, according to iTWire.The problem, can easily be reproduced when a user logs into the 'guest' account, either on purpose or by accident, and when they log back out of the account and back into their normal one, they find that their account has been fully reset with all data wiped and lost - the account is like a brand new one. The home directory still exists under "/Users/username" but is completely empty.
Users are reporting that the data is unrecoverable and cannot be found anywhere on the hard drive, and the only way to restore it is if the user has been performing backups on a separate hard-drive. Apparently the problem has been present since a few days after launch, as the forum post dates back to 12th September, but as of yet, Apple has been silent.
It seems the only work around at this stage is to disable the Guest account, or at least disable it and then re-enabling it so that it's a native Snow Leopard account. Another suggestion is to create a new account and enforce parental controls, if you really need a temporary account.
It's not clear how many users are affected, but it seems like any user who had Leopard before the upgrade, and had the guest account enabled are affected and are at risk.
Update: CNet has published a method to restore the files from a Time Machine backup to a new, identical user profile. If you have lost files due to this problem, and have an intact backup please follow the steps found here - the restore process may take over two hours to complete.
Update #2: Apple has acknowledged the problem to CNet in a prepared statement late yesterday announcing:
"We are aware of the issue, which occurs only in extremely rare cases, and we are working on a fix," an Apple representative said in a prepared statement Monday."
Update #3: For those who are concerned that they could be affected, our recommendation is to disable the guest account fully. If you require it though, make sure you make a complete backup of your hard disk before you try the account again if you upgraded from Leopard to Snow Leopard, just to be safe.
















It is not a bug, it is a feature.

...but I wasn't aware that guest accounts were really used anymore
Actually, no they are not. I'm not underplaying the severity of this bug, but I find it odd so many people are logging in to their "guest" accounts, it's not really easy to do by accident. Oh well, this kind of thing really should not make it through QA.
You mean because maybe there are a lot of people that might not use their computer exactly the same way you do? I know, crazy. Unless you took of a poll of every Mac user, then how the hell do you know "actually, no they are not."? That's right, you don't.
Who says they are doing it by accident? It does have a purpose after all. Claiming that you know how everyone else uses their computers is ridiculous.
Really?
What purpose, I have never used it, can't see a use for it. Maybe you can enlighten us.
While this is a huge bug, and there is no excuse for it, it would never affect me or a lot of people I know.
Gee, maybe the name itself "Guest Account" might provide you with a clue. Try not to think too hard about it though!
I can see it ticking off a home user, who let's their kids use the computer and then bam their files are gone. Who get's blamed? The kid of course.
Sadly Apple probably isn't liable.
In most western nations (and any country with consumer protection laws) there is an 'implied warranty of merchantability'. The idea is that anything you sell comes with an implied guarantee that it suitable for the purpose for which the product or service is sold. For example: If I sell you a hammer it's implied that it's suitable for driving nails. If the hammer shatters when you try to pound a screw into sheetrock then I may be found at fault and you could be entitled to some form of restitution (or if my product shatters and severs your arm: I could be responsible for the harm and in sever cases subject to negligence charges).
The implied warranty does not require that a product be suitable for all purposes for which an item may be used. For example if my hammer worked fine for driving nails but you decided to use it as a garden tool and it rusted: I'm not responsible for that and even if you were injured you wouldn't be entitled to compensation.
Exactly how far merchantability laws go is unclear. Some companies err on the side of caution: that's why you see things like electric heaters "not to be used as a floatation device": the company is concerned that somebody, somewhere will try to use their heater in a pool, get electrocuted, and then file a complaint. Having the fine print would allow them to defend against claims. It's mostly motivated by American legal victories but the EU isn't totaly safe either.
In the case of EULAs there haven't been many tests of "fitness to the purpose". Some countries have found that a customer can't sign away their consumer rights in an EULA or otherwise (refunds on bundled copies of Windows is the case that comes to mind) but the last time I checked there were no firm findings that operating systems are required to be 'suitable for the purpose of running your computer' (ridiculous: right?)
Realistically this will play out exactly the same as every other data loss bug in the history of computing: an update will be released and everyone will forget.
It happened last year in Windows Home Server: saving files (under certain circumstances) caused them to be erased or become corrupted beyond recovery. It was fixed a month or two after being reported and that was the end of that. This issue springs to mind because it hit my parents, whom I think were the only people on earth to ever buy one of those boxes. I vividly remember getting the call: I was face down, naked, hungover, and laying in a puddle of water at the cabin…the phone rang "The computer lost Coronation Street, how do we get it back?!"

How is using the guest account (which Apple provides) not a reasonable senario?
You might also ask how moving files to a Windows Home Server box (which is bullet point #1 on the bo
The point is: there is a long history of data-loss issues caused by software where the consumer is ultimately left holding the bag. If you don't agree with that write a letter to your local consumer protection agency, minister of industry, and member of parliament/senator. This is something everybody needs to do because even if Apple or Microsoft were to be held to responsible for this sort of thing in one country (ie: England) that wouldn't apply to people living in the Americas or Asia.
In the case of Apple specifically - they have this to say about the implied warranty of merchantability:
wrt. to EULA enforcability, there are two possible outcomes:
Specific to software: the courts have ruled that licenses that signing-away first-sale rights in the USA are not valid (see Autodesk v. Vernor). In the EU extended consumer protections (like buyers remorse protections) have been ruled to take precedence over EULA limitations. You'll often see lines like the "if your nation doesn't allow time limits on warranties to be set then this bit doesn't apply". Provided a contract was entered in good faith courts will strike down individual provisions, not the entire contract.
In order for a successful suit to be launched against any developer you would have to prove several things:
0. Let's just grant this as a sure thing for the purpose of argument.
1. Has never been established that implied merchantability applies to software (just like establishing murder vs manslaughter has rules, so does determining if the IWM applied to a product). IMO it's possible to make a reasonable case that no such implied warranty exists. Depending on where the case is brought I think this could go either way.
2. Is easier said than done. In some jurisdictions I think that could be shown (the EU, it has much better consumer protection rules than the US). The UCC does allow you to disclaim implied warranties (I checked in my old business law text from university) but it's possible that the court may limit this in certain circumstances. It's the sort of thing that would be argued out over many years because any verdict would be appealed at least once. If I bet on lawsuits I'd say this is a long shot but it could work out in some places.
3. Is extremely unlikely, probably even impossible. Courts are guided by previous rulings and in those cases the courts have always decided that simply nullifying the contract is appropriate.
4. Establishing this would be very difficult due to the somewhat nebulous nature of merchantability requirements. The easiest to way to think of it would be if you were arguing a fight between two white guys was a hate crime. You might try to argue one guy was a neo-nazi and the other was a xionist but both would be able to put forth a strong defence that it was a simple assault. If you can't prove it was a hate crime then you can't go forth with the trial (we'd be assuming simple assualt isn't a crime for the purpose of this illustration).
That's why you don't see "Oh you lost my data: pay day!" class action lawsuits. The issues are very complex.

No, but the surviving members of the family are likely to sue.
Microsoft has pulled a stunt like this. Microsoft also claims in advertising that they are the most stable and secure, they even produce sponsored studies proving this. The government has not stepped in in the past, with the chkdsk bug that deleted data.

How is intentionally deleting files or formatting your hard drive even remotely related to this? If you type in a command to delete all the files on your drive and don't expect to lose your files, I'm sorry but you're just stupid. There's a huge difference between typing in cryptic commands and simply logging into your guest account.

Registry crashes do though, which are sometimes just as bad, when the registry autobackup hasn't worked for whatever reason.
Yes, it has happened to me. *sigh*
The installed apps all get borked, you lose tons of settings, and you can then just as well backup your data and reinstall Windows.
Yeah, but that's a bit different from this bug. At least when Windows has an issue logging you in because of a corrupt user profile registry your documents etc. are still intact!
It takes a couple of simple registry errors to cripple a Windows installation. I've had one incident where even a repair install wouldn't fix it because it simply reproduced the error again instead of fixing it--brilliant!
I have used Windows since Windows 3.11. But I still cannot understand what a "registry error" is? Can you enlighten me?
P.S. And no, I don't consider bad sector on HDD corrupting some files file "registry error".
No undelete possible...eesh!

Ferment an apple and you get cider, yum yum yum... ferment windows and you just get uPVC and glass
You got a problem with uPVC and glass?
I think MS should be above that.
With Microsoft having over 90% of the desktop market, they don't need to sling crud.
They have that high percentage because the average Joe on the street is too stupid to know that there is anything else.
Yet not stupid enough to buy an overpriced iAppliance that will delete all our data?
I would say not throwing money at a company to feel part of a "community" that worships overpriced PCs, is pretty damn smart. Ok, back to playing games. Wanna lan?
Yeah, they're "stupid" because they didn't buy an overpriced status symbol. I think I hear an Apple fan crying.
Microsoft has way too much class for that.
wow, just called most of the people on this site stupid huh? Way to make friends....
Hope they get this sorted quickly...
In fact you keep things VERY bare since you know you'll have to wipe it as soon as the next beta comes your way.
In this case, it is possible the bug was simply never seen since the beta testers might not have noticed any missing data where there wasn't any before.
(I know I know, it's not an iPhone)
The next Mac/PC guys ad has Justin Long talking and then just going silent with a blank stare that freaks out John Hodgman...
Best Quote Ever!
I am so disillusioned now.
Seriously though. I expect Apple will hold off for the immediate time on showing their insipid ads. Those things are an insult to the intelligence of most any knowledgeable computer user.
I like to compare a Mac to the London Underground. When it's working it's a little piece of heaven that no man can live without. But when it's not, boy oh boy, you better believe it doesn't do it by halves.
Although I have a Mac Pro with Windows 7 being as good as it is I'm tempted to set my startup disk to my bootcamp partition and only use OSX when I feel the need to, which at this rate won't be often.
Why on earth did you buy a Mac Pro then? The only reason I can think of is running software like Logic Pro or Final Cut. You could have built a lot cheaper computer with the same specs if you don't need to use OSX so often, and get a cheap mac mini for the rare occasions you feel like running it.
Yes I'd miss things like Aperture but Light Room is fine and in some ways better.
For the price I paid for the Mac Pro, which was second hand, I couldn't have built a dual quad core xeon system with 12GB ram and 4TB storage for less.
As for Mac Mini's they're overpriced junk, had one, painfully slow. I could have turned my other desktop in to a Hackintosh if I wanted to go that way, did for a short time to make sure everything worked 100% but then saw the Mac Pro for sale.
They ship Time Machine because their OS is buggy and will delete your data? Good to know I guess, lol.
And that's not the point. The point is there's a bug in a feature that is offered by the OS.
When I have Guests over and they wish to use my PC, I enable the Guess account.
On my Windows 7 which doesnt delete data I might add
that's apple fanboys for you !
hmm somehow I vaguely remember something similar now. Who needs and FM tuner on his Ipod?
Its Apple. If it was Microsoft, it would be pinned at top, the news passed to CNN/BBC/etc, forums going crazy, etc.
But since its Apple....Its still cool.
Sounds like this only occurs if you upgrade to SL. A fresh install might be ok. Bad bug all the same.
Backup your ****!

Sad to see that so many others are creaming at their loins over the misfortune of others just over their hatred for all things Apple.
The article mentions a thread that contains 45 posts, most of which aren't from people with this problem, who claim an occasional issue with something that only occurs in a particular method, sometimes but not always. It's not like Windows where such things happen all the time and for months and years.
I'm writing this from an office where the entire place has their Windows computers infected by some virus and I have to wait till the IT guy gets free for our meeting.

But this causes data lost. I also ask you to define Window's fault because AFAIK It doesnt have any for me.
The viruses in your office arent Window's fault, they are the IT admin's fault for not putting a decent antivirus and configuring the computer correctly.
Please dont catch feelings; It is just a OS.
You have pretty stupid people working at your office. The entire place has infected Windows PC's? That's brutal. At least they aren't losing their data though.
The issue is IT gave you admin rights when clearly your staff cant handle it.
Is your 10.6.1 install a fresh install or a update?
Only happens on update.
Maybe trying a full "RTM" type product would be a better solution as your main OS....just an idea, always works for me.

I additionally was unable to install the RC of Windows 7 on a Asus P5VD2-MX motherboard with a Geforce 7300GS graphics card; a couple of users reported that in order to get it to work you had to hack files from the previous beta release, which works, into the RC but that thread, unhelpful to the RC program, was understandably closed down; the assumption has been that the RTM will work. Hope so. I just read that the Snow Leopard bug doesn't occur on machines with a clean install. It does sound to me, though, that Apple tried to get the jump on Microsoft by releasing Snow Leopard a little too early; the next update contains features that should have made the RTM; anyone know if Snow Leopard can be slip streamed?
1. Login to Guest account, logoff
2. Login to your account..
3. Boom..all your datas are gone!

This is by design, like an account on a Kiosk or Internet Terminal, where a user needs to save their data on a USB Key or external HDD.

Now, the question is... who is dumb
Apparently you didn't read the article. Not only does it wipe the guest account clean, it also wipes the main account clean, as well.
I like the phrase "by design" What does it mean? Is it a good thing?
You don't need to imagine it, it happened twice already in Windows. WHS corrupted files, something much harder to detect. And even the Windows 7 Beta decided to trim music files as it pleased.
This isn't any different, it's also not easily reproducible as so far no one in this forum could, upgrade or not.

Ohh yes, that makes sense..compare a beta product to a retail version.
But you're correct it's unfair to compare retail SL with MS betas.
But you're correct it's unfair to compare retail SL with MS betas.
All retail versions are Final. There's nothing "more" or "less" "like a beta" if it is sold to the public at a price.
That is the same excuse being used by the Mac fanboys to justify the latest bug.

yes its supposed to be a home server but how many everyday computers that people use shipped with windows home server actually

Single user mode gives root access. It's not a security flaw as that is its main design.

Yeh but Microsoft doesn't claim their OS to be invincible, Apple does. And anyways a bug like this is as bad as it gets.
Yuck.
Sorry dude... But this IS NOT the only flaw they've had. Snow Leopard has been riddled with problems.
Looks like they have a Software Verification problem.
They Apple edge over Windows is really quality of software engineering. This is therefore not a good sign.
my my, that's terrible!
Just because people do not use Guest accounts often does not mean that this bug is fine LOL
Lol

The repro steps require you have the Guest account enabled in Leopard, upgrade to Snow Leopard, and not do anything with the Guest account settings. I'm not sure if there is anything more specific you need to have, but that's from what I gathered.
I can't repro this issue on machine that I did a clean install of Snow Leopard. I'll try it on the machine that I upgraded from Leopard when I get home, but I didn't have the Guest account enabled so I'm guessing it won't repro there either.

Yeah, it doesn't seem that "rare" seeing as most people would have upgraded in the first place
it is because this beta release for the upcomming MacOS 2.0 (hence 1.6)
Apple ads rag on MS for having viruses and malware. At least Windows doesnt wipe your data just by logging in to the system. I am willing to bet there are a TON of issues with OSX...they just havnt been discovered because most use Windows.
I am just curious on how long it takes Apple to patch this....
Good thing I am using Windows Vista, it is way more awesomer. I can't wait to get 7, it will be even way sweeter! I have used Windows since Windows ME and I think it is so much better than any other operating system. I have wanted to try others, but WHY?
WINDOWS ROCKS!

I can't believe they haven't taken over this thread....shouting everyone down like an "average joe" concerned about Health Care during a local town hall meeting. Guess they are speechless or perhaps on the phone with apple trying to figure out a way to get their data back. Maybe I should be patient! LOL
