Updated to 10.5.5 - now beachball freeze forcing hard restart

A week ago I ran the update to 10.5.5 through Software update, along with several other things (security, itunes). I started getting the spinning beachball, and it's not letting me quit application or force quit anything, I have to do a hard restart.
I dug through these forums and found a potential solution. Download and run the combo update, then reinstall itunes through the download. Did both. Still getting the beachball.
Triggers: It seems to do it every time when I open a PDF made from an Open Office document (opening in Preview). Today it crashed just attempting to open Open Office 3.0 beta. Later it crashed just trying to open the Adobe Acrobat Reader application folder.
I just ran permission repairs. It looked like it repaired somethings, mostly relating to Airport (which I'm not using on this computer).
Any ideas?

There is a major problem with the PDFkit system component.
I have exactly the same problem here. My PDF file is generated by my HP ScanJet device.
The PDFs work well on Adobe Reader on both Mac and PC with no indication for an invalid PDF file.
The files also work well on Tiger (intel/PPC).
Also other files downloaded from the internet are affected.
Just Leopard on intel seems to be affected so far. I am not sure about Leopard on PPC.
It does not matter whether you are having a preview with QuickLook or opening it in Preview.
The interesting thing is that when you run Preview using Rosetta, then the system does not get unresponsive. But this trick does not apply to QuickLook since this is not a stand alone application.
Is there a way to disable QuickLook?

IMac runs slow intermittently; occasional freezes require hard restart.

Recently, my iMac (27", mid-2010, OS X 10.9.3) has begun intermittently running very slow, with occasional freezes requiring hard restarts. I've been keeping activity monitor open and notice that multiple Google Chrome Helpers open (4-5 of them) with each using 98%+ of CPU capacity. Not sure if they relate to the slow response time. They are sometimes open in the activity monitor, but response times on the iMac are normal. Then, suddenly, the iMac slows to a crawl, with 15-45 second beach balls, sometimes followed by complete freeze and crash.
Any suggestions for diagnosis and trouble-shooting?

MacBook Air (Mid 2013/Mavericks) - Freezes, requires hard restart

11-inch, Mid 2013 MacBook Air.
Upgraded to OS X Mavericks in December 2013 - have downloaded every fix/patch as prompted by the App Store.
Relatively simple use pattern - word processing and web work. No bootcamp or 3rd party software, out side of Mozila products (that I am aware of).
Aproximately once every 12 hours (regardless of continuous use), the entire computer freezes. It does not take input from any input devices/including external keyboard and mouse (which I normally do not use). The only way to fix this is a hard-restart.
I have previously suffered from sleep/wake crashes, this is a new sympton of purpose the same problem?
Getting anxious as I approach my final exams - which are written on computers. Apple - which specifically targets students and technologically unsavvy customers - has created a faulty product, unfit for the purpose for which it was sold.
Any suggestions on fixing or mitigating this problem?
My only thoughts have been a link to RAM use? I don't usually browse flash-websites or keep more than one word processing window open at once.!
Many Thanks!

1. This procedure is a diagnostic test. It changes nothing, for better or worse, and therefore will not, in itself, solve the problem.
2. If you don't already have a current backup, back up all data before doing anything else. The backup is necessary on general principle, not because of anything in the test procedure. Backup is always a must, and when you're having any kind of trouble with the computer, you may be at higher than usual risk of losing data, whether you follow these instructions or not.
There are ways to back up a computer that isn't fully functional. Ask if you need guidance.
3. Below are instructions to run a UNIX shell script, a type of program. All it does is to collect information about the state of the computer. That information goes nowhere unless you choose to share it. However, you should be cautious about running any kind of program (not just a shell script) on the advice of a stranger. If you have doubts, search this site for other discussions in which this procedure has been followed without any report of ill effects. If you can't satisfy yourself that the instructions are safe, don't follow them. Ask for other options.
Here's a summary of what you need to do, if you choose to proceed:
☞ Copy a line of text in this window to the Clipboard.
☞ Paste into the window of another application.
☞ Wait for the test to run. It usually takes a few minutes.
☞ Paste the results, which will have been copied automatically, back into a reply on this page.
The sequence is: copy, paste, wait, paste again. You don't need to copy a second time. Details follow.
4. You may have started the computer in "safe" mode. Preferably, these steps should be taken in “normal” mode. If the system is now in safe mode and works well enough in normal mode to run the test, restart as usual. If you can only test in safe mode, do that.
5. If you have more than one user, and the one affected by the problem is not an administrator, then please run the test twice: once while logged in as the affected user, and once as an administrator. The results may be different. The user that is created automatically on a new computer when you start it for the first time is an administrator. If you can't log in as an administrator, test as the affected user. Most personal Macs have only one user, and in that case this section doesn’t apply. Don't log in as root.
6. The script is a single long line, all of which must be selected. You can accomplish this easily by triple-clicking anywhere in the line. The whole line will highlight, though you may not see all of it in the browser window, and you can then copy it. If you try to select the line by dragging across the part you can see, you won't get all of it.
Triple-click anywhere in the line of text below on this page to select it:

Copy the selected text to the Clipboard by pressing the key combination command-C.
7. Launch the built-in Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
Click anywhere in the Terminal window and paste (command-V). The text you pasted should vanish immediately. If it doesn't, press the return key.
8. If you see an error message in the Terminal window such as "syntax error," enter
exec bash
and press return. Then paste the script again.
9. If you're logged in as an administrator, you'll be prompted for your login password. Nothing will be displayed when you type it. You will not see the usual dots in place of typed characters. Make sure caps lock is off. Type carefully and then press return. You may get a one-time warning to be careful. If you make three failed attempts to enter the password, the test will run anyway, but it will produce less information. In most cases, the difference is not important. If you don't know the password, or if you prefer not to enter it, press the key combination control-C or just press return three times at the password prompt. Again, the script will still run.
If you're not logged in as an administrator, you won't be prompted for a password. The test will still run. It just won't do anything that requires administrator privileges.
10. The test may take a few minutes to run, depending on how many files you have and the speed of the computer. A computer that's abnormally slow may take longer to run the test. While it's running, there will be nothing in the Terminal window and no indication of progress. Wait for the line
[Process completed]
to appear. If you don't see it within half an hour or so, the test probably won't complete in a reasonable time. In that case, close the Terminal window and report the results. No harm will be done.
11. When the test is complete, quit Terminal. The results will have been copied to the Clipboard automatically. They are not shown in the Terminal window. Please don't copy anything from there. All you have to do is start a reply to this comment and then paste by pressing command-V again.
If any private information, such as your name or email address, appears in the results, anonymize it before posting. Usually that won't be necessary.
12. When you post the results, you might see the message, "You have included content in your post that is not permitted." It means that the forum software has misidentified something in the post as a violation of the rules. If that happens, please post the test results on Pastebin, then post a link here to the page you created.
Note: This is a public forum, and others may give you advice based on the results of the test. They speak only for themselves, and I don't necessarily agree with them.

Hot CPU Freezes MacBook Pro forcing hard restart

My MacBook Pro early 2011 13" freezes, requiring a hard restart when the CPU temperature stays in the 195 F (as measured by iStat nano) range for more than a few minutes. The fans run appropriately. I am running 16 GB of RAM, most of which is not being used during these 'hot' episodes (according to Activity Monitor). Typically they happen when Mail is trying to connect to iCloud and can't seem to do it. Then the spinning beach ball. Can't force quit or restart from the Apple menu. I'm using 10.7.4 on a dual core i7, 2.7 GHz unit. Any ideas for fixes?

Try these:
SMC/PRAM reset.
See what's loading in login items - delete the ones you don't want loading.
Check Activity Monitor and see what's using most of your cpu resources under all processes.
Once you've determined/see what using most of your CPU %, highlight it and hit quit process.
Once you've done that, do a disk verify then go on to do a verify disk permissions, repair if needed.
Do a restart and see if that helps.

IOS5 update won't work and now phone freezes in restore

I have a 3gs and tried to update last night to iOS5. The download kept timing out, but after turning off my firewall (thanks to another community users advice) it downloaded. Next problem was actually updating. The update froze, and after about 2 hours of non-movement I forced it to quit to try again. Now, my phone won't turn on and is stuck trying to restore. When I connect to iTunes it powers up and tells me I need to restore. No problem - I backed it up, so I'm not worried. But it won't actually restore. It sits idle at about 2% on my iphone screen and at about 25% progress on iTunes. I've left it alone for about 4 hours at a time without movement. Please help! I have no phone now.

Follow Troubleshooting security software. Often, uninstalling third-party security software will resolve these errors.
There may be third-party software that modifies your default packet size in Windows by inserting a TcpWindowSize entry into your registry. Your default packet size being set incorrectly can cause these errors. Contact the manufacturer of the software that installed the packet size modification for assistance or follow this article by Microsoft: How to reset Internet Protocol (TCP/IP).
Verify that access to ports 80 and 443 are allowed on your network.
Verify that communication to albert.apple.com or photos.apple.com is not blocked by a firewall, or other Internet security setting.
Discard the .ipsw file, open iTunes and attempt to download the update again. See the steps under Advanced Steps > Rename, move, or delete the iOS software file (.ipsw) below for file locations.
Restore your device while connected to a different network.
Restore using a different computer.

I updated my MacBook Pro, and now it's to fully restarting.. It's stuck on the grey screen with the loading sign at the bottom of the apple.

How do I fix this issue???

Take each of these steps that you haven't already tried. Stop when the problem is resolved.
Step 1
The first step in dealing with a boot failure is to secure your data. If you want to preserve the contents of the startup drive, and you don't already have at least one current backup, you must try to back up now, before you do anything else. It may or may not be possible. If you don't care about the data that has changed since your last backup, you can skip this step.
There are several ways to back up a Mac that is unable to boot. You need an external hard drive to hold the backup data.a. Boot into Recovery by holding down the key combination command-R at the startup chime, or from a local Time Machine backup volume (option key at startup.) Release the keys when you see a gray screen with a spinning dial. When the OS X Utilities screen appears, launch Disk Utility and follow the instructions in the support article linked below, under “Instructions for backing up to an external hard disk via Disk Utility.”
How to back up and restore your files
b. If you have access to a working Mac, and both it and the non-working Mac have FireWire or Thunderbolt ports, boot the non-working Mac in target disk mode by holding down the key combination command-T at the startup chime. Connect the two Macs with a FireWire or Thunderbolt cable. The internal drive of the machine running in target mode will mount as an external drive on the other machine. Copy the data to another drive. This technique won't work with USB, Ethernet, Wi-Fi, or Bluetooth.
How to use and troubleshoot FireWire target disk mode
c. If the internal drive of the non-working Mac is user-replaceable, remove it and mount it in an external enclosure or drive dock. Use another Mac to copy the data.
Step 2
Press and hold the power button until the power shuts off. Disconnect all wired peripherals except those needed to boot, and remove all aftermarket expansion cards. Use a different keyboard and/or mouse, if those devices are wired. If you can boot now, one of the devices you disconnected, or a combination of them, is causing the problem. Finding out which one is a process of elimination.
If you've booted from an external storage device, make sure that your internal boot volume is selected in the Startup Disk pane of System Preferences.
Step 3
Boot in safe mode.* The instructions provided by Apple are as follows:
Shut down your computer, wait 30 seconds, and then hold down the shift key while pressing the power button.
When you see the gray Apple logo, release the shift key.
If you are prompted to log in, type your password, and then hold down the shift key again as you click Log in.
Safe mode is much slower to boot and run than normal, and some things won’t work at all, including wireless networking on certain Macs.
The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
*Note: If FileVault is enabled, or if a firmware password is set, or if the boot volume is a software RAID, you can’t boot in safe mode. Post for further instructions.
When you boot in safe mode, it's normal to see a dark gray progress bar on a light gray background. If the progress bar gets stuck for more than a few minutes, or if the system shuts down automatically while the progress bar is displayed, your boot volume is damaged and the drive is probably malfunctioning. In that case, go to step 5.
If you can boot and log in now, empty the Trash, and then open the Finder Info window on your boot volume ("Macintosh HD," unless you gave it a different name.) Check that you have at least 9 GB of available space, as shown in the window. If you don't, copy as many files as necessary to another volume (not another folder on the same volume) and delete the originals. Deletion isn't complete until you empty the Trash again. Do this until the available space is more than 9 GB. Then reboot as usual (i.e., not in safe mode.)
If the boot process hangs again, the problem is likely caused by a third-party system modification that you installed. Post for further instructions.
Step 4
Sometimes a boot failure can be resolved by resetting the NVRAM.
Step 5
Launch Disk Utility in Recovery mode (see step 1.) Select your startup volume, then run Repair Disk. If any problems are found, repeat until clear. If Disk Utility reports that the volume can't be repaired, the drive has malfunctioned and should be replaced. You might choose to tolerate one such malfunction in the life of the drive. In that case, erase the volume and restore from a backup. If the same thing ever happens again, replace the drive immediately.
This is one of the rare situations in which you should also run Repair Permissions, ignoring the false warnings it may produce. Look for the line "Permissions repair complete" at the end of the output. Then reboot as usual.
Step 6
Boot into Recovery again. When the OS X Utilities screen appears, follow the prompts to reinstall the OS. If your Mac was upgraded from an older version of OS X, you’ll need the Apple ID and password you used to upgrade.
Note: You need an always-on Ethernet or Wi-Fi connection to the Internet to use Recovery. It won’t work with USB or PPPoE modems, or with proxy servers, or with networks that require a certificate for authentication.
Step 7
Repeat step 6, but this time erase the boot volume in Disk Utility before installing. The system should automatically reboot into the Setup Assistant. Follow the prompts to transfer your data from a backup.
Step 8
If you get this far, you're probably dealing with a hardware fault. Make a "Genius" appointment at an Apple Store to have the machine tested.

Just updated to newest version ios now can't force my apps to close. everything I open stays open. Updated all the apps still no help.

Headline says it all. Other than this problem everything working pretty well. Thanks

Double tap the Home button, then swipe upwards on the App Preview (not the App Icon). Tap the Home button again to return to normal screen.

IMac Suddenly Plagued with Freezing (requiring hard restarts)

I've owned Macs for years now and can count on one hand the number of times I've seen my machines freeze enough to where I couldn't recover and had to hard reboot it.
Now, after having my iMac for probably close to a year it's suddenly freezing over and over. It first began the other day after about 15 minutes of being on the computer (only had Safari and one other program open), I restarted and within a couple minutes it froze again. Restarted.. froze again within like 15 seconds. I've never experienced anything like this on a Mac (brings back awful Windows memories)..
Anyone more computer savvy than I have any clue what this may be? Doesn't seem to have anything to do with programs since it did it with absolutely nothing running. Hard drive maybe? I recently reformatted my system, would another reformat help at all?
Thanks guys for any help,
Jordan

It did once freeze while I was booted from the disk (I held "c" at startup) and as it came up it froze. However, it never did that again and I did reformat and install OSX again last night using that start-up disk and it didn't freeze at all during installation.
Yet, low and behold after 10 minutes of installing updates once the new OS was done installing it went to this all grey screen suddenly (same color as when you boot up a mac), freezing there.
Hard drive still you think or maybe video card? I hope this isn't a $700+ repair
Edit: oh by the way the hardware test I did was the one where you hold "D" on start-up, the hard-drive test was ran both from the bootup disk and while in OSX, both said HD was OK.

ITunes freezes forcing hard reset

Hello,
I recently experienced a never-ending beachball while writing a message in Mail. iTunes had been open while writing the message. Since then, whenever I launch iTunes, it bounces in the dock for ever, and as soon as I click elsewhere or command-tab, the whole system freezes. If I don't click/command-tab, it will presumably sit there forever, beachballing while the iTunes icon bounces in the dock (I have left it for up to 15 minutes). Everything else on the system works fine.
I have tried resetting the PRAM and repairing disk permissions. I have not received a single error message through this, but I cannot open iTunes.
I am on a 2009 13" MBP (2.53ghz 4GB), running 10.7.1.
I would appreciate any assistance the community may provide.
Regards,
Paul

ANYONE?

Source Monitor 'Freezes' Forces PPro Restart. Glitch, CS6?

Hi all,
I have been experiencing an issue with the source monitor in several projects built in CS6. Occasionaly, I will double click a clip in the project window, or even right click and 'Open in Source Monitor'. Most of the time this functions successfully and the clip appears in the monitor, but at some point clips, any clip, refuses to open/appear in the source monitor. The source monitor enter a 'frozen' state and will have a strange appearance for example displaying the audio meters from the 'Audio Mixer' tab. It seems the only way to cure this once it has occurred is to close PPro and re-open the project. At this point this is proving to be a waste of time and a kink in an editor's flow.
Has anyone else experience this symptom?
Thanks,
Lindsay

OJ8600 scanner freezes, forced to restart WIA

I am the sys admin at a company. One of my users occasionally has an issue with her OfficeJet 8600 where it will halt mid scan and I have to cancel the scan, restart the printer, and restart the WIA service otherwise it gets an error about not being able to communicate with the scanner. It's not a huge inconvenience, but I would really like to know what the problem might be and how to permanently fix it. Suggestions?

Have you tried running the HP Print & Scan Doctor program?
Is the firmware on the 8600 up to date?

HT1688 I updated my IPhone 5 to IOS 7 and after that now it freezes when I try to type anything.

I got a new IPhone 5 at the end of July and it worked just fine, but when I updated to IOS 7 now it freezes anytime I type something. I can push the letters on the screen and then about 1 minute later they will display on the screen. I even updated to IOS 7.0.2 hoping this would fix this problem, but it did not.
I doesn't matter if it is a text or in an app on the phone I can't type with the keyboard with out a long dely in the time I type the letters and the time they appear on the screen and then if is misspell or misstype something then I have to wait again to delete it and retype it.
What can I do to fix this problem I have rebooted the phone several times and it continues and I have even HARD booted the phone by holding Home button and top button to lock or power off until it shuts off and then turned it back on and it still does the same thing.
I can't really use my phone to type anything it is very frusterating!!!!!!

I have Sprint and all my friends have other carriers. There's are working perfectly fine. I have an iPhone 5 and since I updated it, it gives me an invalid SIM message. I called sprint and they told me to take out the sim and put it back in after a minute. No matter what I do, after about an hour of restarting it it shows "Invalid SIM"

I updated to Safari 6.1 and now it freezes when opened

Yesterday I updated to Safari 6.1 and now it freezes when opened, although the overall system stays up. I updated to the latest Java and iTunes 11.1.2 at the same time. When I open Safari now, it pauses for a few seconds without going to the home page and then I get the spinning beach ball. I get two messages: One says that the plug-in for SplashID Safe has not been tested with this version of Safari (a message that I had been getting before the update and never caused a problem). The other message says, "Crash Protection It appears that Safari didn't quit properly. Do you want Glims to re-open your tabs anyway?" It gives me a choice to click "Cancel" or "OK". I have tried clicking them (before the beach ball appears) and it makes no difference. The version of Glims I am running is out-of-date.
The only available crash report is almost a month old and therefore is of no help.
I made a back-up with SuperDuper just before updating and can reverse the update if I do it soon, but I would like to get this working.
I would appreciate any advice.
Bill

>>The version of Glims I am running is out-of-date.
How do I uninstall Glims?

A day ago I updated my iPhone4 to io5 and I updated iTunes on my PC using Windows 7(64 bit). Now iTunes freezes upon opening and I have to force it to close. Anything I missed along the way?

A day ago I updated my iPhone4 to io5 and iTunes update as well. I use windows7 (64bit). now iTunes freezes at open and I have to force it closed. Anythng I missed along the way?

Many thanks.
With those symptoms, I'd try the following document:
Apple software on Windows: May see performance issues and blank iTunes Store
(If there's a SpeedBit LSP showing up in Autoruns, it's usually best to just uninstall your SpeedBit Video Accelerator.)

Updated to 10.5.5 - now beachball freeze forcing hard restart
