System locks up 3-4 times daily since OS X update ... anyone?

I have been fortunate to own a mac since the 80's and I have never experienced OS locking up like I have with Yosemite... 3-4x/day ...Any feedback?
I use my Mini (2.6GHz, i7, 16GB, intel HD graphics 4000 1024 MB) for internet, bills, iTunes, and photos. No games, no videos, no art ... just old school use.

Open Disk Utility and select the drive then Repair Permissions. If it returns a lot of problems, run it again. Then restart the Mini. See if that clears the issues you are having.
If it does not clear things, restart on the recovery HD partition, restart and hold the Command and R keys, from Utilities on the menu bar select Install Mac OS X and reinstall the operating system. When that completes, Repair Permissions and see if the Mini works right.

HT203177 I have not backed up my computer using Time Machine since before I updated to Mavericks. It has been "preparing backup" for a half hour at least and shows no indication of how long this may take. Is something wrong?

No. TM has to look through your entire drive contents and copy them all. This will take some time.
Once the first backup is made, then subsequent backup will be much quicker, depending on how much data has changed since the last one.

I'm having some sort of text tone glitch with my iPhone since the IOS5 update, anyone having the same problem?

I
have a second hand iPhone, now since the new update my text tone which is the Tri-Tone seems to glitch and repeat the first part multiple times very quickly and then carry on every time I receive a text. I'm just wondering if there is anyone else having the same problem or is it just me?

Thanks, Sig.
The old computer is a 2.6 Ghz Intel Core 2 Duo
The new one is a 2.3 GHz intel core i7
In going over this, thanks to "tallking it out" with you, I did discover the Text Edit problem. Because I've still been unable to get the new computer text size (fonts or whatever) to match the old computer, I did not notice that the curser is now different--the line midway down the curser has to be placed on the line I am working upon, otherwise the edits go elsewhere on the page. Now, with a bit of difficulty, I am able to get Text Edit to work correctly.
If you have any ideas as to why my menu bar and Text Edit type are still so slow, I'd love to have them.
(I went through the process you suggested earlier, re my Trackpad preferences, and found no improvement.)

So tired of Fireforx crashing multiple times daily! Happening 2 updates ago or so. Did all the recommended fixes. Sending crash results have yielded nothing!

I used to run a lot of add-ons and never had a crashing problem with FF. But with every update I have been forced to remove more and more add-ons. Now, I only have those that are really essential to me. Yet, I have more crashes than ever. FF keeps thanking me for my crash test results but never fixes anything! Maybe it's time for FF to accommodate the add-ons rather than the other way around -- since that's how it used to be. My add-ons never caused crashes. What's the good of running FF without add-ons to see if it crashes, if you really need the ad-ons? I really don't want to use IE, but FF is trying my patience to the limit. How about actually analyzing MY crash results and sending me an email that says more than "Thank you," but rather, "Here's why your crashes are occurring." Come on, guys -- get with it!

Excuse my ignorance, but what is the purpose of the crash report if it does not diagnose the cause of the crash?

Incorrect time displayed since iOS4.1 update

Title says it all really. I have it set to set the time automatically, and it is currently displaying 2 hours fast. I can correct it by manually setting the time, but this never happened with 4.0.2

Turn off automatic time set, verify that your time zone is correct, and turn it back on.

My iMessage is sporadic since ios 7 updates. anyone else?

iMessage will sometimes work & sometimes not-getting to be more not since I updated my iPhone 4. Is anyone else having this problem besides me & my daughter??? Suggestions please? Hve tried rebooting & this helps for maybe a few messages then back to not working.

This did help for a few days but it is back not working again. Works on iPad but not on iPhone. Very frustrated!!!!

Can't send or forward email since 2.02 update

Past couple of days haven't been able to forward or send emails via my 3g iphone; just realized have had problem since 2.02 update--anyone having this same issue?

Hi Karen,
I've been dealing with this issue on certain servers since 2.0 came out. My friend made an appointment at the Genius Bar and for 1.5 hours they tried and finally replaced her iPhone. Even after replacement it still does not work for receiving. The problem has gone to engineering and we are waiting for an update.
We are using a small server (atanda.com) with offices in Oakland, CA. Here's what I know so far:
Everything works fine on wifi, it's only on EDGE there is a problem. If you are using EDGE most of the time you can send email using the outgoing server settings:
cwmx.com on port 25 with no SSL and no authentication.
As for the incoming we are waiting to hear from engineering. My friend in Germany used my settings on his iPhone and there was no problem sending or receiving using T-Mobile (no wifi).
All this info is assuming you are using a POP account on a small server. If not, I have lots things you can do from 20 calls to tech support including many transfers to Product Specialists as well as a couple of hours of head scratching at the Genius Bar.
Good Luck.

10.7.2 Lion freezing / apps lock up, must hard reset 2-3 times daily

I've seen several posts on this -- oddly, some of them are archived even though there has been no resolution...
Would love to hear people's experiences and especially if you have a fix. Would REALLY love it if Apple would get off their duff and give us a working O/S.
Ever since upgrading to Leopard I've been having problems with system stability and, specifically, with lockups. Usually this starts out with a few applications get "hung" (beach ball). Again, usually, I can force quit them, restart and continue for at least a little while... but, it always marks the beginning of a downward spiral. The final straw seems to be when Finder locks up. Once Finder locks, the system becomes unresponsive overall and I can't shut down without doing a hard reset (either cmd-opt-power or, more often, just hold power until a get a hard reboot).
Some of the behaviors I'm seeing:
Apps start to lockup. Best option at this point is to quickly shut everything down and restart. On occasion I get a software restart if I'm prompt about it.
Finder locks up... forget it. Hardware restart is in my future... will generally try to save work, but it seems that anything involving disk / file system access is completely frozen.
About one out of two times, the login screen is very slow to appear (about a 2 minute boot), and then it fails to respond to my wireless keyboard &/or mouse. Sometimes the mouse works, keyboard doesn't. If I wait for 1-2 minutes, it will usually "wake up" and suddenly gets all of the input in one blast... but usually I lose patience, open up the laptop, do another hard reset.
Sometimes the screen saver won't release control of the machine (much like login screen). I can move the mouse, tap keys, etc., screen saver just keeps right on running blithely along...
On rare occasion, even the force quit panel (cmd-opt-escape) refuses to appear.
Of late, I've taken to launching Terminal on login so that it's available (because after the lockups start, I won't be able to launch it). Then, I can issue a "shutdown -r now" which, most of the time, seems to work pretty well. I hate doing a hard reset, always worried it will lead to a damaged file structure or lost work.
I've tried a number of fixed, including (at the height of it) reinstalling 10.7.2, which I did a few days ago. It made no difference at all... Also tried resetting NVRAM, etc. About the only folklore I haven't tried yet is switching to Chrome or Firefox. A lot of people are blaming Safari for all of this, so perhaps I'll try that next...
I'm suspecting that Time Machine is making the situation worse, but turning it off (and disconnecting the drive) does NOT solve the problem. It seems to go a little longer in-between system lockups. Same symptoms... apps become unresponsive, one after the other starts to beach ball, eventually the whole system locks up... I'm wondering if it has something to do with disk access, as posted in other threads. I've been trying to minimize disk access wherever possible, for one, just plugging in my Time Machine drive about once a day, let it backup, then unplug. Not really sure if it's helping or not though.
Currently, I'm running into this on average 3 times daily (worst day was 6 times, best day was just once, yay...) Yes I've been keeping track. By my count I'm also losing up to two hours a day, because the shutdown / reboot process is so baby-sitting intensive (and I have to do it several times a day).
Very, very frustrating. This is definitely the worst O/S release Apple has ever put out there. I'd like to go back to Leopard, but worried about the downgrade... arrrgggh. (Wish Mr. Jobs was still around, somehow I think he would never have tolerated this...)

Magic Mouse's connection drops about every 15 to 40 minutes of typing, often in this Discussion. Apple Care suggested that keeping my battery charge above 50% would solve it. It didn’t.(My batteries are Apple’s, as is the charger.);
When I return my hand to the Magic Mouse, the active window often suddenly scrolls up which looses the position of the pointer. This can cause problems in graphical apps like InDesign;

In Mail, stationery does not work properly. Neither of these two is an earth-shattering fault, but having been offered them I wasted a lot of time trying to get them to work.)
Time Machine three times over the last 1 1/2 years (OS 10.5 once and Lion twice) has complained that its HD is full when it is only ~1/2 full. A full reset on the last two did not cure it (I had not discovered Pondini's Full Reset until Lion). Pondini's symptom's and solutions did not match the error. Each time I had to erase and start again;
A couple of months ago, as a test, (after confirming my daily bootable backup of my system done by Carbon CopyCloner), I re-installed Lion from the InstallED.dmg, accepted the invitation to restore from TM, and upgraded to 7.2. All looked well except Mail displayed only the Header and first two lines of the body of messages, all the rest of the bodies were blank. Another major thing did not work after this re-installation (I can't remember the details now);
Carbon Copy Cloner can fail to find its Firewire backup HD about every 10th time (I have a daily schedule). The connections to the drive are plugged in OK but the drive is no longer mounted, whether the iMac has been restarted or woken up. CCC has been absolutely rock solid for years until Lion;
My Canon scanner (current driver, and it always worked before Lion), more times than not complains that it cannot start because it is in use elsewhere. I have to unplug its USB and re-connect.
In SystemPrefs > iCloud, a dialogue box said that Sys. Prefs. wants to use confidential info in my keychain. I press “Deny” and the box returns for ever until I force quit Sys. Prefs.
Software Update repeatedly tells me that a certain update is available but I already have installed it.
For those silly enough to install a new OS within a year of its introduction (not me: my iMac came with the wretched thing in it), some bugs can be expected, but not this many (at least in my opinion). All previous updates going back to 1997 have gone much more smoothly than Lion on my machines.
Although I am in a minority (given the huge number of sales of Lion – although MacWorld reports that sales of Lion are faltering), I am sorry to say that I have fallen out of love with Apple. I would gladly trade the elegance and the fancy features for a bit of “Works out of the box”, “It just works”, “Computing for the rest of us”.

System lock ups when using hard disks

At first I thought I had the same issue as in this thread however after reading his logs I decided that it is unlikely since the topic opener seems to be getting a bunch of
Apr 4 17:00:15 daxteriv slim[708]: (Do:882): GLib-CRITICAL **: Source ID 46 was not found when attempting to remove it
, so I decided to start a new thread.
I am not getting anything in my logs when I look at them after the crashes. It seems as if whatever is causing the issue makes it impossible to write to the drives so nothing seems out of place until after it's too late, and quite obvious that something is wrong. The sole exception to this was some complaint about ata9.00, however this seems to have been a red haring since the complete removal of this drive solved nothing, though it did make the error go away.
I have run memtest, and prime95 (in windows since at the time I didn't want to boot my system) both coming back negative. I also checked for SMART errors, particularly UDMA errors. Again, negative.
Here are some previous threads of mine that I believe to be all related to the same issue:
https://bbs.archlinux.org/viewtopic.php?id=195449
https://bbs.archlinux.org/viewtopic.php?id=193937
https://bbs.archlinux.org/viewtopic.php?id=192704
[edit3] My previous thought was that this was a btrfs issue, however now I think it may be more hardware related.[/edit3]
Last night I was writing urandom to a new drive and I woke up in the morning to see that it had stopped prematurely, but not due to lack of space. The system had not locked up completely, which was new, however, as soon as I did something that accessed the disks (tried using the Gnome Dash), all hell broke loose. I immediately hit the power button, which would start a shutdown. I didn't know about REISUB, or I would have tried that. In anycase the shutdown failed and I had to hard reboot.
The evening before I was playing games just fine and doing normal activities.
Also, the other day, while booted into the live cd I think it started to crash since it was acting extremely bizarre, but I shutdown, successfully, before it could do more than complain a lot. At the time I was in the middle of scrubbing a btrfs volume after a system lock up. I think, but am not certain, that I saw on my motherboard "A5" which, according to the manual indicates "SCSI reset", but I had an extremely bad viewing angle. I know neither if what I think I saw was correct, nor do I know if the system was again in the process of a meltdown.
In general there is no activity that seems to be able to instantly trigger this, though in each case, if my memory serves me well, there was a constant stream of data either to or from a HDD.
My set up is that I have 5 HDDs, and an SSD. One HDD has Windows, my fallback installation of Arch, and daily backups. Another drive, which I just installed a few days ago currently only has single 50GB btrfs partition that is not part of any sort of larger volume. I also have three other drives each with four parttitions each involved in a btrfs volume. At the top is a 175 GB volume in a RAID0 configuration, after that is a 25GB partiton in RAID1, then a 650GB partion (RAID1), and the remainder of the disk (about 80GB) is in single. The RAID0 is has games on it and sometimes for short term storage (a few hours), the 25GBx3 RAID1 is used for Arch as well my ~/.local, ~/.cache, ~/.thunderbird, ~/.mozilla, and ~/.config. The 50GB partition I mentioned is currently doing the job of this volume, and was not mounted last night, but has been before. The 650GBx3 is used for long term storage of just about everything, in particular ~ is mounted here. The single configured volume is used for downloads, storing ISOs and installers. The SSD is used for caching those partitions used in the RAID0 volume with bcache. I DO NOT think this is a bcache issue since the RAID0 volume has never had any errors.
My motherboard is a ASUS X79-DELUXE which has the SATA controllers: Intel X79 Express Chipset, Marvell 9230, ASMedia 1061.
[edit] Oh, I'm on kernel 3.19.2 and btrfs is 3.19.
[edit2] Also, I converted the RAID0 to a single in case that matters.
[edit4] I finished scrubbing and copied my "journalctl -b" output to pastebin. I can't see any thing that might raise any flags. http://pastebin.com/WXpbpTuc

nstgc : it's hard to tell if your problems are memory related, but memtst often needs multiple passes to detect errors.
How many passes did you let it make ?
Is it possible for you to take out say half of the memory chips and see if that changes anything ?

Random system lock-up or freeze / Linux 3.4

Hi
My system seem to regularly lock-up in the linux 3.4[1] series. Whenever this happens, I had to power cycle the system by holding down the power button. Keyboard, numlock, mouse wouldn't work. I'm still looking-out for a pattern that trips this lock-up consistently. The lock-up doesn't happen for days and can happen every other day as well.
During this lock-up nothing gets captured in the system log too. I parsed 'journalctl -a'. Here is a sample from such a lock-up:
Jun 30 18:01:01 chaembian /usr/sbin/crond[4747]: pam_unix(crond:session): session opened for user root by (uid=0)
Jun 30 18:01:01 chaembian /USR/SBIN/CROND[4748]: (root) CMD (run-parts /etc/cron.hourly)
Jun 30 20:45:03 chaembian kernel: Initializing cgroup subsys cpuset
Jun 30 20:45:03 chaembian kernel: Initializing cgroup subsys cpu
I noticed the lock-up around 18:30 and instead of forcing it to shutdown, I thought I would give it sometime to snap out of it. But nothing happened until 20:45, when I forced the restart. The only other anomalies are (picking out their first apperances):
Jun 25 13:57:33 chaembian kernel: BUG: Bad rss-counter state mm:ffff880115e10a80 idx:1 val:-2
Jun 25 13:57:34 chaembian kernel: BUG: Bad rss-counter state mm:ffff880115e10a80 idx:2 val:2
during shutdown
and

Jun 10 10:08:57 chaembian kernel: NOHZ: local_softirq_pending 08
during boot[2]
I'm not sure if these precipitate the lock-ups but these are the things that stand out in the logs for my untrained eyes.
> uname -a
Linux chaembian 3.4.4-2-ARCH #1 SMP PREEMPT Sun Jun 24 18:59:47 CEST 2012 x86_64 GNU/Linux
Let me know if you require any more information.
1 - I was a regular -ck patched user. Since the time the series started serving 3.4 series, I was having lock-ups. Since the stock was still at 3.3 then, I was using the stock as I was trying understand the issue from the logs. But ever since stock moved into 3.4, the lock-ups are happening in this as well. Again, since I have not been able to recreate the issue on demand, I'm not able to attribute the regression to 3.4 conclusively.
2 - A similar issue that was reported from last year will be System lock-ups or software resets, with increased ethernet activity. But the key difference is that my logs have just one instance of this message generated at the time of boot.

Yes, that's how I have it setup. Until today's forced power cycling earlier today, the journal had all the entries from June 10th. The system gets proper shutdown daily (there is a power shortage where I live and to counter there is a scheduled, daily power shedding for 1 hour).

System lock-ups after upgrading to Tiger

This topic was previously posted in 'Installation & Setup'.
After 3 days (and 18 views) I got no replies.
Maybe that forum was not appropriate, so I decided to try it in this forum.
About 4 months ago I exchanged my 80 GB Hd in favor of an 200 GB Maxtor 6L200P0. One day later I upgraded OS X 10.3.9 to Tiger (retail DVD).
At that time I experienced a frequent (several times a day) lock-up of my system.
No messages, nothing, not even after powering down and restarting.
After some time I figured out that the lock-ups occurred on Internet access. Clicking on a link in Safari, posting messages on Discussions. Even Mail locked the system a few times. Also Corripio (artwork and lyrics finder for iTunes) caused the system to lock.
After that, I decided to perform an Archive & Install (first time after almost 4 years of using this Mac). Except from having to re-install a number of 3rd party apps. the system seemed to perform well. No lock-ups were experienced for a few weeks.
Problem solved, I thought.
Although far less frequent than before, I do experience those annoying lock-ups a few times a week.
Here are my questions:
What could be the cause of the lock-up?
Is is advisable to perform a Clean Install? What advantage do I have of, it opposite to performing an A&I. I'm reluctant to perform a clean install at the moment, because I haven't found a few serials of commercial and shareware applications yet ( I know, I should have written them down :-/ )
Any hints/tips to track down the exact cause?
TIA
M
P.S. ( I do have a bootable complete backup of my HD on an Maxtor Onetouch II )

Hi, M.
1. You wrote: "What could be the cause of the lock-up?"The number of potential causes range from disk corruption or bad applications to serious hardware problems, such as a defective logic board.
2. You wrote: "Any hints/tips to track down the exact cause?"I suggest treating the "lock up" problem — better described as a "freezes and hangs" problem — similar to a kernel panic as the basic troubleshooting and hardware testing steps are virtually the same. See my "Resolving Kernel Panics" FAQ.
It provides a comprehensive roadmap which you should follow from beginning to end, in the order specified in the FAQ.
2. You wrote: "Is is advisable to perform a Clean Install? What advantage do I have of, it opposite to performing an A&I."The term "Clean Install" does not apply in Mac OS X. That is obsolete Mac OS 9 terminology. The closest Mac OS X equivalent to a "Clean Install" is an Archive and Install with the Preserve User and Network Settings option, which it sounds like you've already tried once previously, but you may want to try again as part of the troubleshooting process I outlined above. See my "General advice on performing an Archive and Install" FAQ for some important tips on this process.
The other options are:
• Archive and Install without the Preserve User and Network Settings option: This reinstalls the OS and wipes out both your accounts and your network configuration, but preserves the previous System folder.
• Erase and Install: Erases the hard drive, i.e. Macintosh HD, and reinstalls the OS from scratch, preserving nothing: your accounts, network settings, and everything else on the drive are deleted.
Of those two, and since you have a bootable backup, the second (Erase and Install) would be the second-to-last thing you would try, the last being taking the machine in for service.
Good luck!

System locks up when trying to play streaming media after installing i-tune

Hi Folks,
Ive just bought the greatest piece of kit ever, a 2Gb Nano.
Great kit but since installing i-tunes my system locks up whenever I try to play any streaming media (wmv etc) via windows media player. Cntrl-Alt-Del even locked out. Total lock up.
Ive tried re-establishing file types in quick time and windowd media player and even installed lasted windows media player but all without success.
I'm using WinXP pro SP2.
Any ideas?
Cheers,
Gene Stevo.
