    Hey again,

    I wanted to give you all an update: The machine was sent off to apple (by the reseller I got it from) where they supposedly replaced the power supply and logic board. Two weeks went by with no problems, then when switching to the high performance gfx card last night, I logged back in to be greeted with the same problem!

    New information- I had reset the clock to do a time machine backup before taking it in. Once at the store- the problem couldn't be repeated - until I clicked "automatically set date and time", then viola, all the errors returned.

    I'm going to try my best to get an exchange, assuming it is in fact hardware. Good luck.

    Hi Guys

    I have had my MBP just over a year and after an update last night 5th June 2010, when I booted up this morning I had all these issues, Time & date, Mail Accounts, Network Password.

    What causes this and how can it be fixed? Never had problems with Power or Networks previously.

    Help needed Thanks

    I think your problem is the same. Did you try checking the date? If it is before 2008, you'll need to sync it with a time server then reboot.

    The question is, +did they replace the clock battery?+

    Seems the clock only resets on boot, then.

    Hmm. When I clicked “automatically set date and time” and logged out, then logged back in, all of the errors were solved.

    My guess is that the battery that keeps the internal clock running is failing. When the computer is on, the clock runs from the normal battery, right? Then on shutdown, it switches to its own battery, right? That would make sense: if the clock battery is failing, the time would be okay while the computer is on because it'd be relying on the normal battery, which seems to be fine in all of our cases. When the computer shuts down|reboots, the clock would switch to its own battery, which would not supply it power, having failed. The clock would then do its version of blinking 0000; resetting to before 2008. That would cause the symptoms outlined earlier in this thread.

    Hey TC,

    Thanks for all of your input on this problem. I spoke to an apple specialist over the phone earlier this month, who suggested that since there had been so many hardware replacements, it must be software. He instructed me to reinstall the OS, and install all of my software one by one, every 24 hours.

    I think the clock battery being the issue makes sense, and on a normal PC tower, that is located on the motherboard. If they did in fact replace the logic board, wouldn't the battery have been replaced as well?

    Anyway, I did a fresh install of the OS (not using the time machine backup) and slowly installed all of my software, trying to pinpoint anything. During that time the computer has been completely shut down many times.

    Last night I installed the iStatpro dashboard widget, and this morning for the first time in about a month, i got "Clock set to Jan 1, 2008" error, as well as "Do you want krb5kdc to accept incoming connections?", as well as all of my wifi passwords being forgotten.

    Could that widget really be the cause? I really feel like it's doubtful.

    Thanks again for all your help!

    You're welcome.
    I highly doubt that will work; this seems to be an issue with the clock battery.

    I'm not sure, did you ask them?

    Same symptoms.

    I doubt it. I've had that widget for a long time, and it doesn't seem to have caused any problems.
    However, you may want to uninstall the widget, reboot, reinstall it, and reboot again. If you don't get the symptoms while you're doing that, then the widget is probably not the cause.

    I think you may have synced to a bad time server. I use 0.pool.ntp.org , which supposedly syncs to an atomic clock.

    Many of these problems with being asked repeatedly at startup, whether you want to allow an item (configd, mdnsresponder, krb5kdc, etc.) to accept incoming network connections, or losing your wifi password, etc., happen when a computer running a Unix-based OS crashes or gets powered off accidentally instead of being shut down. Sometimes this damages one or more of the files used for network access, time setting, etc.--among other kinds of damage, these files can become "unsigned", which basically means their security settings are messed up, and so they've become "untrusted" (I'm still looking into more details on this, so that's the best way I can describe the issue at the moment). Someone who knows the proper commands could possibly fix these damaged file settings using Terminal, but I haven't found much reliable info on how to do that. However, some people (including me) have found that reinstalling the latest OS X Combo updater for whatever version of OS X you're running, reinstalls good copies of these files. Some people could see the same symptoms caused by different things, as described in this thread (a problem accessing a time server; bad PRAM/clock battery; scrambled PRAM/NVRAM/etc.), in which case reinstalling the Combo updater may not help.

    If resyncing the date fixes the problem, how can that be the cause?

    Hey all,

    Wanted to give one final update on this problem. In addition to the errors above, my computer started shutting itself down (intermittently) when carried around or moving the hinge from 90 to 45 degrees. It also started having problems dimming the screen- it would give a dimming "flash" for a second, go to full brightness for a second or two, and then go dark/out. It could then be woken up (usually).

    After speaking to a very helpful customer relations agent, I was able to go through the steps to receive a replacement machine.

    It's been my experience that you either never have a serious hardware problem at all, or it's bad enough it gets replaced. Awesome computers, though.

    Thanks again for the help TC.

    guys,

    i had same problems, losing wifi password, wrong OS Time etc...
    i think it's something to do with file permission.

    I ran Disk Utility and did Verify Disk Permissions. found lots of file with permission problem.
    Everything was back to normal after Repair Disk Permissions.
    ( guess the Disk/file permissions got messed up after the software update...somehow )
  • Allan Leedy Level 2 Level 2 (245 points)
    Same problem, same result: repair of permissions fixed it for now.

    I started having this same problem IMMEDIATELY after rebooting after updating to Safari 5.0.3 on my MBP. This did not happen on my 24" iMac.
  • lucienp1 Level 1 Level 1 (0 points)
    I had the same problem and resetting the time manually seems to have solved it (for now) but I
    1) don't have a Win partition nor use bootCamp
    2) the computer was plugged IN at the time the problem occurred (I had shut down and turned it back on because of an audio issue I was having) so it was safely shut down (one thing that people mentioned) and plugged in (presumably eliminating the other probable cause (that the battery was dead))

    Why hasn't apple put anything in any of the dozen threads that I've seen with this problem on HOW to PREVENT OR FIX THIS?

    The same thing happened to my macbook today. I didn't even discharge the battery completely, maybe it was 80% charged, and I switched it off and plugged the adapter. In the morning, the main battery was 100% charge (of course), but then I guess it only runs on the "other" battery when it's shut down.
    (BTW, so this would be comparable to the little "button" battery that keeps the bios settings on a desktop motherboard, right?)
    So I should bring it to an Apple store? Now AFAIK there are only 2 apple shops in Italy, and I live quite far from both of them... I'm willing to bring it in myself, just to avoid having it shipped by other people (plus probably having to endure more time without it), but if I do so, I would like at least to have it fixed in one go (as I understand from some previous posts that some people had to go more than one time)...

    Also, why is there no mechanism to automatically recognize if the computer clock has been reset?? Mine was reset to 2001-01-01... it shouldn't be that hard to recognize that something's wrong, on a 2009 macbook, right?
    They say apple makes it easier for the end user, but I had to google "krb5kdc mDNSResponder"... -.-'
