Updated: Major bug in Snow Leopard deletes all user data

Advertisement (Why?)
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.

Isn't it great how when this happens to Apple people just turn it into a joke whereas if this had happened on Windows it would be a major issue which would never be forgotten about...

I'm sorry Apple but this is a major failure in what is supposed to be a very secure system.

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.

Hold Apple liable! They trumpet OS X as the most stable and secure computing platform yet they deliver total crap like this. If Microsoft pulled a stunt like this, the FTC and trial lawyers would be all over it like flies on s***. This is one of the most clear cut cases of diceptive advertising ever.
#4.1 billyea on 12 Oct 2009 - 05:14
they should be held liable, yes. But advertising really has nothing to do with it, it's advertising.

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.
#4.2 +evn. on 12 Oct 2009 - 05:57
rafter109 said,
Hold Apple liable!

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.
They trumpet OS X as the most stable and secure computing platform yet they deliver total crap like this. If Microsoft pulled a stunt like this, the FTC and trial lawyers would be all over it like flies on s***. This is one of the most clear cut cases of diceptive advertising ever.


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 or simply plugging in a firewire drive (which is pretty much the only thing you an do with one) not a reasonable scenario?


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:
Your exclusive remedy under this Section shall be, at Apple’s option, a refund of the purchase price of the product containing the Apple Software or replacement of the Apple Software which is returned to Apple or an Apple authorized representative with a copy of the receipt. THIS LIMITED WARRANTY AND ANY IMPLIED WARRANTIES ON THE MEDIA INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY, OF SATISFACTORY QUALITY, AND OF FITNESS FOR A PARTICULAR PURPOSE, ARE LIMITED IN DURATION TO NINETY (90) DAYS FROM THE DATE OF ORIGINAL RETAIL PURCHASE. SOME JURISDICTIONS DO NOT ALLOW LIMITATIONS ON HOW LONG AN IMPLIED WARRANTY LASTS, SO THE ABOVE LIMITATION MAY NOT APPLY TO YOU.


wrt. to EULA enforcability, there are two possible outcomes:
  • EULAs are unenforceable. The only conditions where onerous EULA conditions were found to be unlawful were cases of click-through agreements. In those cases Microsoft/Dell (possibly others) had EULAs that were said to be 'accepted' immediately upon turning on a computer and/or opening a sealed package (in both cases you couldn't read the EULA before accepting it). One of the conditions of the license in question said the user lost the ability to return the software for a refund. The courts rejected that specific portion of the EULA. They also held that EULAs were binding provided they could be read prior to accepting the terms of the license (Apple includes a paper version in every box and allows you to read it electronically on all of their systems before you agree to it). If any part of a modern EULA is going to be rendered unenforceable it won't be because a user was unable to enter into the contract knowingly.
  • The specific disclaimer wrt. merchantability will be rendered unenforceable. In the past courts have ruled certain portions of an EULA is unenforceable even if the customer 'knowingly' accepted the conditions. I couldn't write an EULA that says "by agreeing to this license you are my slave": it would be struck down.

    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:
  • A bug exists, it causes data loss (0)
  • That implied merchantability warranty is valid wrt. computer software is valid (1)
  • That any disclaimers in the EULA are unenforceable (2)
  • That the remedy offered in the EULA—typically return the software, end your license, and receive a refund—is unacceptable (3).
  • That the bug in #1 means the software doesn't live up to merchantability requirements (4).

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.

Sounds like the Sidekick users who have lost all their data are going for a class action lawsuit. Not sure whether it's different that the data was lost due to there being no backups compared to a software bug. You could say the software wasn't fit for purpose in which case there could be a case???

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.

This is a huge bug, but lets not get too excited about it. Do you know what schadenfraude is?

Happy as a clam Windows user here, but it shouldn't be forgotten that very early on, Vista had a problem where deleting something in the file pane might accidentally delete the entire folder. This got some degree of attention, though it doesn't seem nearly as bad as losing all of your information just for using a basic feature that shouldn't have anything to do with file removal in the first place.
#5.3 mmck on 12 Oct 2009 - 09:04
Guest user accounts do have something to do with file removal - they are designed to remove all files used upon logging out. I believe this fault makes the normal account think it is a guest account and so proceeds to delete everything.

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.

#26.1 excalpius on 12 Oct 2009 - 10:04
Indeed. The tough part here is that when you beta an OS you don't do production work on it, so you don't often save many files you want to keep, etc. etc.

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.

Things like this and the fact that every major OSX release isn't really ready until 10.x.2 or sometimes later (and they seem to be getting worse with each release, not better excluding 10.0.0 which was beta quality) shows that Apple's choice of secrecy and only limited beta testers just doesn't work. They should release public betas, as MS do, which provides a massive amount of testing (many, many man years worth), of course it means more work to administer/monitor all the feedback but it's not as though they're a 1 man band.

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.
#32.2 m.keeley on 12 Oct 2009 - 17:34
Because I like OSX, however you do get fed up of all the half baked releases. Snow Leopard is the latest in a long line of versions that has been released too early, they're already seeding .2 with about 100 bug fixes on top of what was fixed in .1 Just not good enough.

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.

Not defending Apple at all in this case, but honestly, what percentage of people actually enable the guest account on their OS (ANY OS????). In all my years of using computers (I'm 38, and have had a computer since I was 12), I don't think I've ever enabled it, not on Windows, not on the old Mac OS, not on OS X, and not on Linux. I've just never seen the need. If I want to allow someone else to be able to access the computer, I create a user account for them. It's usually actually quicker and easier than trying to figure out how to enable the Guest account (depening on the OS).

Because, as Roadwarrior mentioned, using the Guest account is very rare. Not defending it in anyway, but, you would be hard pressed to find someone doing beta testing on such an account. I'm inclined to believe that whatever was changed in the code for that function was believed insignificant, so it wasn't thoroughly tested. I have three Macs and haven't been affected by any of these major bugs. I definitely feel for those that have, though.

Both Windows 7 and Snow Leopard are great OSes that are ready for prime time. Windows 7 has had its major bugs ironed out already. This bug in Snow Leopard is apparently not easy to reproduce, and will not even work on a clean install. So if you were planning on buying a new Mac, this wouldn't even affect you. Linux, for the most part is as stable as you'd be able to make it; the more knowledge you have, the better it will work for you.

I know, I put my neck on the block by relating my experience as a warning to others, but I agree and said as much in my post.

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?

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.

Unfortunately .0 releases of OSX are often more like beta than retail versions, you can be certain that .1 and .2 will arrive shortly after.

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.

Just read about another neat bug in SL allowing you to bypass the login password.

"Find an account with no password (using the guest account results in data loss).

Now go to the login screen and click the account with no password, then quickly click on the account that HAS a password. Do this fast enough and you can login to your account without typing your password."

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

I'm sure you're aware that pretty much any operating system has the ability to reset an administrator password, given that you have physical access to the machine.

.0 releases of OSX have always been bad. There was a problem with Leopard at one time where if you were moving files to a network share/USB... and for any reason that connection went down then the remaining files were deleted. So basically rather than copy & delete the source only if the copy was successful it would delete regardless!

The people debating whether the use of the guest account is likely are missing the point. In this case, it would seem the fundamental *nix security model was compromised. Who cares if data loss is likely or not, an account was able to write to files to which it did not have permissions. This is a major failure up for a BSD-based OS.
Unless some daemon running as root wiped the directory, or the log-in screen.

Although Apple says it's extremely rare, from what I've read it effects anyone who has upgraded rather than doing a fresh install. So I'd imagine a lot of people have the problem, how many ever log on as Guest is another matter.

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.

Granted, not many people use GUEST, but Apple should be more complete with their testing. Lots of people like to tinker around and check out new things with their system...and lots of people DO NOT backup their data. So all it takes is one person who doesnt backup and messes with the guest account.

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.
