back to article Snow Leopard data-munching bug predates Snow Leopard

Fanboi complaints of a mystery data-munching Mac OS bug began well before the arrival of Snow Leopard, Apple's latest desktop operating system. Similar tales of woe date back to at least November of 2007, when Jobsian cultists were still using the previous Mac OS version, just plain Leopard. This week, the web is awash with …

WTF?

Apple are crap - it's official!!!

They have known about this bug for years and not bothered fixing it even in their super new Snow Leotards.

What a monumental fucking failure!!!

Weired, but nothing that's outside of the big idea

Most Macs aren't made to store data on them. If that would be, Apple would include more than a single harddrive into their computers so you could make a RAID. Most Macs are made to be appliances. Easy to use and a bit limited, but certainly not meant for storage.

So of course it's a shame, but it's nothing the user shouldn't be prepared for.

Hey moron, almost every OS has bugs in it dating back some years. The Linux Kernel will have and you can guarantee Windows sure as hell does (you know, that's why there's still updates coming out for XP) so stop being a dick-waving Windows homeboi and grow up.

Painful lesson...

"I had 250GB of data without backup and I lost everything"

I've know too many people who, despite prompts and advice from me, don't consider backing up data to be an important use of their time... until this happens. (Of course, then it falls to me to help them try to recover what they can!)

Or should I say The First Cowardly Cultist of Jobs?

See the thing here is yes there are a lot of bugs, but the problem your failing to recognize is that Apple is always about it just works (except when it doesn’t or was this the almighty disc cleanup feature?) , therefore his comment was not out of line. Anytime there is an article about an OS (and I will say I'm no saint here) there is always fanboism to no end in the comments. Personally I try to bash all of them equally.

What makes this bug even worse is the fact its not easily reproduced, and its a rather bad one to have floating around in the open. How long till haXors figure out how to reproduce it and have some fun with the Apple crowd? Not everyone backs up and although Macs are in a lot of ways superior to Windows I cant recall the last time I logged into an account on Windows and had all my data deleted on me. And how many people who own Macs got them just because they heard how good they were and don’t know the first thing about using a computer short of surfing pr0n, checking email and playing games on Pogo?

Think about that anyway back to the regularly scheduled flames and I reiterate what I said in an earlier post.

Need more Disc space? There’s an app for that!!

If you don't back up....

My opinion; backing up costs about $100 and about 10 minute's time, to buy an external hard drive, plug it in and configure backups.

If you aren't doing them, that's a clear statement by you that your data isn't worth $100 and 10 minutes of your time, so what are you whining about?

Surely there's nobody who doesn't know that computers can crash and lose data? Everyone from kids to computer-illiterate octogenarians know this, so there really is no excuse.

don't believe it

I've used the guest account plenty of times on my Leopard MBP. No problems. (It does say that it is going to delete the guest account data). The only time I've lost files is when I've dropped one of my external hard drive (the back-up) and had to undelete stuff from other drives, Data Rescue II is good for that.

those knocking OSX should remember back to Windows home server......

Is there no software in Snow Leopard, or that works with Snow Leopard, to recover lost data. Surely there is!

Probably not the same thing at all, but...

Trying to debug a rights-related issue on XP, I downgraded my usual login to "Power User". Couldn't reproduce the problem. Went to "Restricted User". Nope, still not there. Gritted teeth and reduced to "Guest". Still no sign of the problem. But my whole profile had been vaporised. Pif! No warning, no "Are you sure", just blown away.

I no longer save important files in my user profile.

SUMMARY OF RECENT EVENTS

1. Data is lost by some idiot(s) out there.

2. A bug is discovered in an OS.

3. Much QQing subsequently occurs.

4. ??? *

5. Profit

Notes:

* sensationalising said news in an online tech journal and further letting sad old gits comment on it to further fan the flames, boosting circulation and hence ... (5)

One can replace (1) + (2) with any/every issue easier than replacing a kernel module. And one online tech journal frequently does.

Anyone and everyone is fair game here on El Reg, it would seem, as it should be, imho.

At any rate, Apple _is_ evil despite how nice their kit appears to be. Not hitler evil, I should qualify, but more globocorp evil, but you get the point. Therefore they deserve any ribbing they get.

Never a fan boi be y'all. Do not be blinded.

Wow, there are bugs and there are bugs - tough to see any way to call this one short of enterprise critical! Each OS has its own strengths and weaknesses of course, and their share of bugs, but this seems to be a spectacularly mentally serious one, I'm frankly gobsmacked it wasn't sorted by throwing every dev in the company at it once it was discovered two years ago. This kind of thing could really damage your reputation as a caring cuddly computers for the terrified company.

Attention all Mac defenders.

Go ahead and keep believing your precious Mac is perfect and invulnerable to all threats.

It's fun to take you sorry bunch down a peg or two now and then.

Remember in the Kübler-Ross model:

1. The first stage of grief is denial. Denial that your precious Mac is indeed flawed.

2. Second stage, anger. Anger that the Prophet Steve Jobs and his holier than thou marketing department lied to you all these years about your Mac being perfect and that it "Just Works".

3. Stage three, bargaining. "I promise not to be such an arrogant douchbag to all those individuals not running OSX or any other fruity labeled consumer electronic device".

4. Stage four, depression. "I am such a sad person thinking I am better than all the PC users out there. I truly made myself look like a fool".

5. Stage five, acceptance. Accepting the fact that your Mac is really no better or worse than a PC.

After that, the healing can begin.

Get over it Mac/PC/Linux users. COMPUTERS SUCK. PERIOD. Can't we just all be friends with a common love for technology, regardless of platform??

See, not funny.

Haven't owned a Windows PC in 2 years, been Mac, but I still think Windows is a fantastic O/S, it has opened up computers for everyone, from little 4 year-old kids to 90 year-old biddy's, everyone can now use a computer, thanks to MS vision to market some already great ideas. The biggest problem Windows has is the soft spongy thing in front of the screen, now we're all PC savvy, it's time to rationalise an learn how to control the tools properly.

I use Windows and Linux at work and crApple ( see it just get's funnier everytime I use it! ) at home. At work I need to get stuff done, Unix SA stuff off the Linux box, Windows is great at displaying the email, working on the sheets and writing up the reports, conecting across the network to all the shared resources. At home after fighting all day with machines, I want to turn on, tune in and drop out, three clicks and I have email and I've checked the news and done.

I appreciate the wonderfil diversity of PC platforms, live and let live!

Why are so many using the Guest account?

Nobody seems to be asking these people what they're doing in their guest account - you have to wonder. I'm not saying that mitigates this horrendous bug in any way... just wondering.

Did they not know Safari has had a "Private Browsing" mode for a couple of versions now?

Known since 2007?

Er, that would be "rumoured since 2007".

What Apple knew in 2007 was that one user (of unknown technical literacy but we do know that he or she doesn't bother with backups) lost all their data and blamed the guest account facility. Apple also knew that it worked for their developers and for everyone else who had ever enabled the guest account.

What Apple have learned since then is that several other people (with similar levels of technical literacy) have lost all their data, done some googling, and blamed the same cause. Meanwhile, squillions of other happy users are using the guest facility without issue, including all Apple's developers.

Without a reproducible test case, it is *really* hard for Apple to justify spending much time on this bug at the expense of other issues which are known to be real.

Had a Mac for 12 months, logged in as guest to do certification and other stuff, never lost anything. Back up running to 1Tb Toshiba external hard drive through Time Machine, documents backed up to Dropbox. Who gives a fuck about data loss? - Back up or lose it you fuckwits!

Still better that formatting my drive every 3 - 6 fucking months, spending time worrying about the 1000's of fucking trojans and viruses that could infect my machine at any moment, dealing with application crashes and BLUE FUCKING SCREENS. Best thing I ever did was move away from Microshite.

I'd rather be on Linux but it just ain't there yet.

If you sell a product, you don't have to say 'it just works'. It should work!!!! MS sold the server OS also knowing about the bug. As long as it gets fixed, no problem.

re: a bug since 2007. Like I said. I have had NO PROBLEMS!!!!

Please tell me how they fix a bug that doesn't always appear? When I test my apps (not OSs I'm not that clever), I check them on different kinds of computers/OSs as possible, with as many people as possible. If a bug is found I fix it. If one isn't found, I can't fix it!

No data loss

Apparently (from what I've just been reading) NO data is deleted. What actually happens is the user is removed from /etc/passwd. So, you should be able to create a new user (with a different username) and log in and see all your data. Alternatively you could boot the machine in target disk mode and mount it on another machine or if you're a power user edit /etc/passwd from a shell.

there is a rule that all users of all operating systems should follow

BACK-UP YOUR DATA REGULARLY!!

I've used my guest account recently (it's enabled because I'm using that undercover security application, so I want the person stealing my laptop to be able to use the thing so I can see who they are, keylog what they are doing, and hopefully get an IP address!!!).... nothing was lost... but if it had been, I'd have been annoyed for all of 10 minutes, because I keep weekly backups of my data using time machine...

I should in theory have mozy enabled too, but they had a bug in their software that rendered time machine backups corrupt for some users - hilarious no?? Incidentally, where was el-reg's coverage of that data issue?! I believe the bug is fixed now, so I'm planning on reinstalling that too - incase the house blows up or something. So we have immediate on-site backups, and if that goes too, off-site... some might say ott - but it's better than losing 10 years of digital photos, music, documents, etc. It doesn't matter what my laptop is, linux, osx, windows - I will always be backing them up like this... have to admit though, backup using time machine is possibly the easiest I've used so far, almost too easy... :S

Official Statement

Recently there have been a number of reports around the data loss bug that, while rare, can cause a Snow Leopard user's home folder to be deleted upon logging into and out of the guest account. These reports may have people concerned about their data in OS X, but in reality it is a very rare and easy bug to avoid, and also it is much easier to inadvertently overwrite a file or accidentally trash one than be caught by this bug and other behaviors that may lead to data loss.

YOU FUCKING FUD PUSHING TOSSERS!

No backup?

Who has 250gb on a hard drive without a backup? External drives are really cheap these days. Combine this with using an unproved, recently released operating system. My Apple is still running 10.4. I may not be able to run all the latest software but I still have all my data.

Ignoring the trolls: Intermittent bug fixing is extremely difficult.

I'm going to ignore the fanbois and the trolls....

This bug looks to be highly intermittent, probably requiring a set sequence of events, which no-one has yet documented fully, to trigger. It probably requires a "perfect storm" event.

Just because this sort of bug is old doesn't mean that it's any easier to find and may be so illusive that even setting developers on the prowl for weeks trying to find it and fix it will do no good. So, I don't fully blame Apple, having software development and bug fixing experience myself, all be it on a smaller scale.

This is not to say that the bug isn't important, or even critical. If the cause can be found no doubt Apple will produce a fix, eventually.

Well said that man. Computers do suck. Which is rather nice, 'cos if they didn't I'd be out of a job!

Also we shouldn't be too hard on non-techie types either. We know about backups and data loss as we deal with it on a daily basis. The truth is, most normal people out there have probably had a few computers in their life and the worse that they lost was a file when they overwrote it. Until shit happens, you really don't think you need to backup. Fact.
