Why does my iPad randomly shut down and then restart?

This has only happened since the newest iOS update. It has also had problems with the wifi happening since the last 6 level update: randomly drops wifi signal etc.
What can I do? I've tried backing up and doing a factory restore, the problem doesn't resolve.

I'm not sure. I didn't buy it, I won it in a contest at work and I don't have any of the reciepts or anything for it.

While transferring files from one external hard drive to another, my MacBook Pro routinely would freeze and often render a message to hold down the start button until it shut down and then restart. I have i7 why does it keep locking up?

You can go back to original hardware; run Apple Hardware Test even.
Remove 3rd party RAM ( much rarer I think )

My ipad keeps shutting down and then rebooting

My Ipad keeps shutting down and rebooting, is this fixable?

Try this - Reset the iPad by holding down on the Sleep and Home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider - let go of the buttons. (This is equivalent to rebooting your computer.) No data/files will be erased. http://support.apple.com/kb/ht1430http://support.apple.com/kb/ht1430

A few days ago my G5 started to freeze up while in use. It doesn't matter if in Safari, iTunes, Pages, etc. The cursor will not respond nor does any keystroke, force quit, escape, etc. I have to hold the power button down to shut the computer down. Then, try to restart. Sometimes restart will work and the computer will work for a while and then freeze again. Other times on restart, instead of the Apple logo at start up, I get a Zero with a line thru it, have to power off and restart again. When it does restart, the "spinning gear" takes a lot longer than normal to spin up and take me to the login screen. Have been told it may be my hard drive getting ready to fail. Have looked at disk utilities, S.M.A.R.T looks fine, "verified" and have verified disk, and repaired permissions. In case it is the hard drive, I bought external hard drive and hooked it up to Time Machine. The backing up to a long time, overnight, about 10 hours because it kept freexing up and I would have to shut down and try restarting again. Finally got everything backed up.
Any help or suggestions greatly appreciated!!! Could it be my hard drive is dying? Is the the normal chain of events or is it something else???

Ok, to copy the Drive from one to another, get carbon copy cloner to make an exact copy of your old HD to the New one...

Believe it or not, anything on the Desktop uses 3 times the Resources of the Mac than if stored elsewhere, I can note a slowdown from just 30 items on the Desktop on a really fast Mac, so the less the better on the Desktop.
DW will not tell you about Bad Sectors, it's just the very best at Repair Directory damage & such.
At this point I think you should get Applejack...
http://www.macupdate.com/info.php/id/15667/applejack
After installing, reboot holding down CMD+s, (+s), then when the DOS like prompt shows, type in...
applejack AUTO
Then let it do all 6 of it's things.
At least it'll eliminate some questions if it doesn't fix it.
The 6 things it does are...
Correct any Disk problems.
Repair Permissions.
Clear out Cache Files.
Repair/check several plist files.
Dump the VM files for a fresh start.
Trash old Log files.
First reboot will be slower, sometimes 2 or 3 restarts will be required for full benefit... my guess is files relying upon other files relying upon other files! :-)
Disconnect the USB cable from any Uninterruptible Power Supply so the system doesn't shut down in the middle of the process.

On new MBP I keep getting message that I need to shut down and then restart

I just got a new 13" MBP. I took the old 500GB 7200 rpm HD (which was operating perfectly) out of my old 13" white MB and put it in the new MBP. Now at boot I get as far as a gray screen, then I get a black screen with text in several languages saying that I need to shut off and then restart the computer. I went through this drill 5 times with no indication that anything was improving. I am sure that the edge card connector is fully seated on the old HD. Any ideas as to what is happening here?

The Operating System for the old and new machine is different, you can't just swap drives like that, what you're getting is a Kernel Panic.
You need to install the OS from the install discs that came with the new machine onto that hard drive. Boot from your new install DVD (hold c at start) and do an Archive Install of the OS so it saves your user data.

Why does my Ipad keep going black and then back to the apple logo. It eventually goes to the start page but then blacks out again. I have already rebooted several times with no luck!!

Why does my Ipad 2 keep going black ahd back to the apple logo. It eventually goes to the home screen and allows me to try something else but after about 30 seconds it happens again. I have already rebooted several times?

Make Sure iOS is updated to the latest version
Reboot the device by pressing and holding down the home and sleep/wake buttons (power) at the same time until the apple logo appears on the screen, then let go.
If that doesn't work then reset the device by going to settings/general/reset/reset all settings

Why does my iPad 1 shut down then reboot by itself?

We have a first gen iPad that suddenly has begun shutting down by itself, then rebooting. Of course, it's just out of warranty (by 2 months). I've read some posts that suggest it is battery related, others that it is related to software. Any help from the experts out there would be great!

Hi amy,
I really doubt it is battery related, as batteries usually last a few years, however in some rare occasions there could be some form of fault.
It sounds like maybe there are some dodgy connections inside the device, which only a repair can solve.
Try restoring your iPad in iTunes - Plug the device in, and click restore under the summary tab.
If this doesn't help, I reccomend heading to an Apple Store and booking a genius appointment - these are free even if you have no warentee. Here they can discuss options with you, and will offer you a discounted replacement price. As your warentee ran out so shortly before the problem arose, they may be able to offer an exemption, ask nicely!
Regards,
Nathan

My 2 week old ipad randomly shuts down and sometimes will not let me type web address into browser.

Sometimes my ipad will just restart itself (the screen goes black, and the apple icon appears and then it's back on). The battery will be higher than 50%. Also, when this is occurring frequently, the web browser will not let me type an address in. When I tap on the address bar it sends me back to my home screen. It will connect to the internet during this time, so I know it's not a internet connection problem.

When in doubt, reboot. Press and hold the sleep and power buttons until the apple logo appears. Ignore the red slider. You may simply be overwhelming the memory. From time to time, doulbe click on the home button to see the task bar. Touch and hold any of those icons until they jiggle, then delete them by touching the minus sign.

How do I get Thunderbird to connect to a properly-configured Office 365 mail account after shutting down and then restarting the client?

I get my Office 365 account set up and working in Thunderbird. I can download and send mail just fine using the auto-detect or manual account settings recommended by Microsoft/Outlook/Office 365. Everything appears to be working as it should as long as the client stays open. When I shut the Thunderbird client down and restart it, it can no longer access the Office 365 mail account. I get a popup error message:
The current operation on 'Inbox' did not succeed. The mail server for account (my Office 365 account) responded: User is authenticated but not connected.
It has no problem connecting to Hotmail, Gmail and other email services, and I can access Office 365 through the web client, but Thunderbird refuses to connect. If I remove the account and re-add it, I can have full access to my email again, but only as long as Thunderbird stays open. If the client gets restarted, it's gone again.
How do I fix this?

I think you might be having a cached password problem. I was having it and was able to resolve by deleting my stored password in Thunderbird. I referenced

Macbook Pro Randomly Shuts Down and Restarts

Hi There,
This issue appears to have occured for other people in different forms but there does not appear to have been a conclusive answer to the problem, so here's hoping someone here might be able to provide some further insight into the issue, and with some luck, a solution.
I have an early 2008 MacBook Pro running OS X 10.7.2 (plugged-in to power) that has started to randomly shut down and then restart itself (goes through all the start up screens; Apple logo etc.). It doesn't appear to be just a straight restart of the machine, but it shuts down, and then a couple of seconds later, reboots, as though it is two different actions...
The computer does this pretty randomly, and now quite often. It happens when applications are running, Safari for example, and when nothing is running and i just go to open Finder or use Spotlight.
I haven't had this issue in the past (some 3+ years of full time use now) and as far as i'm aware, nothing changed on the computer immediately prior to the issue occuring (no updates, installs etc.).
I've checked the systen log which, each time the issue occurs, returns the message 'Previous Shutdown Cause: -128'. I've sought reference as to what this refers to, but it would appear to be a mystery to the WWW.
I have tried the following solutions with no success:
- Proper restart and reboot of system;
- Repair permissions;
- Reset SMC;
- Reinstall OS X.
Any thoughts on what the problem is, what the '-128' refers to, or what more i can try to solve the issue?
Your help is much appreciated! Thanks.

I know this is a really old thread, and everyone's probably already bought new computers now. However, I'm still using my 2010 MacBook Pro and have been experiencing this very frustrating issue. However, I think I just found a way to open a finder window that prevents the shut down. In Finder>Preferences>General, under "New Finder windows show", I had "All my files" selected (BAD?), which probably was the cause, because setting that to "Desktop" instead has prevented shut downs, for now. Just thought I should share this tip, in case anyone else suffers from this annoying issue. If anyone has a better tip or a real fix, please post a reply! There are still people, like myself, working on these older machines who would appreciate the info. THANKS!

Glitchs like that sometimes happen
Try:
- Reset the iOS device. Nothing will be lost
Reset iOS device: Hold down the On/Off button and the Home button at the same time for at
least ten seconds, until the Apple logo appears.
- Restore from backup. See:
iOS: How to back up
- Restore to factory settings/new iOS device.
If sit still reocurrs a lot, make an appointment at the Genius Bar of an Apple store since it appears you have a hardware problem.

Since installing OSX 10 my iMac randomly shuts down and restarts. I can not determine why this is happening. Any ideas?

Since installing OSX 10, my iMac randomly shuts down and restarts. I can not determine why this is happening. Any ideas?

1. This is a comment on what you should and should not do to protect yourself from malicious software ("malware") that circulates on the Internet. It does not apply to software, such as keystroke loggers, that may be installed deliberately by an intruder who has hands-on access to the victim's computer. That threat is in a different category, and there's no easy way to defend against it. If you have reason to suspect that you're the target of such an attack, you need expert help.
If you find this comment too long or too technical, read only sections 5, 6, and 10.
OS X now implements three layers of built-in protection specifically against malware, not counting runtime protections such as execute disable, sandboxing, system library randomization, and address space layout randomization that may also guard against other kinds of exploits.
2. All versions of OS X since 10.6.7 have been able to detect known Mac malware in downloaded files, and to block insecure web plugins. This feature is transparent to the user, but internally Apple calls it "XProtect." The malware recognition database is automatically checked for updates once a day; however, you shouldn't rely on it, because the attackers are always at least a day ahead of the defenders.
The following caveats apply to XProtect:
It can be bypassed by some third-party networking software, such as BitTorrent clients and Java applets.
It only applies to software downloaded from the network. Software installed from a CD or other media is not checked.
As new versions of OS X are released, it's not clear whether Apple will indefinitely continue to maintain the XProtect database of older versions such as 10.6. The security of obsolete system versions may eventually be degraded. Security updates to the code of obsolete systems will stop being released at some point, and that may leave them open to other kinds of attack besides malware.
3. Starting with OS X 10.7.5, there has been a second layer of built-in malware protection, designated "Gatekeeper" by Apple. By default, applications and Installer packages downloaded from the network will only run if they're digitally signed by a developer with a certificate issued by Apple. Software certified in this way hasn't necessarily been tested by Apple, but you can be reasonably sure that it hasn't been modified by anyone other than the developer. His identity is known to Apple, so he could be held legally responsible if he distributed malware. That may not mean much if the developer lives in a country with a weak legal system (see below.)
Gatekeeper doesn't depend on a database of known malware. It has, however, the same limitations as XProtect, and in addition the following:
It can easily be disabled or overridden by the user.
A malware attacker could get control of a code-signing certificate under false pretenses, or could simply ignore the consequences of distributing codesigned malware.
An App Store developer could find a way to bypass Apple's oversight, or the oversight could fail due to human error.
For the reasons given above, App Store products, and other applications recognized by Gatekeeper as signed, are safer than others, but they can't be considered absolutely safe. "Sandboxed" applications may prompt for access to private data, such as your contacts, or for access to the network. Think before granting that access. Sandboxing security is based on user input. Never click through any request for authorization without thinking.
4. Starting with OS X 10.8.3, a third layer of protection has been added: a "Malware Removal Tool" (MRT). MRT runs automatically in the background when you update the OS. It checks for, and removes, malware that may have evaded the other protections via a Java exploit (see below.) MRT also runs when you install or update the Apple-supplied Java runtime (but not the Oracle runtime.) Like XProtect, MRT is effective against known threats, but not against unknown ones. It notifies you if it finds malware, but otherwise there's no user interface to MRT.
5. The built-in security features of OS X reduce the risk of malware attack, but they're not absolute protection. The first and best line of defense is always going to be your own intelligence. With the possible exception of Java exploits, all known malware circulating on the Internet that affects a fully-updated installation of OS X 10.6 or later takes the form of so-called "Trojan horses," which can only have an effect if the victim is duped into running them. The threat therefore amounts to a battle of wits between you and the malware attacker. If you're smarter than he thinks you are, you'll win.
That means, in practice, that you always stay within a safe harbor of computing practices. How do you know what is safe?
Any website that prompts you to install a “codec,” “plug-in,” "player," "extractor," or “certificate” that comes from that same site, or an unknown one, is unsafe.
A web operator who tells you that you have a “virus,” or that anything else is wrong with your computer, or that you have won a prize in a contest you never entered, is trying to commit a crime with you as the victim. (Some reputable websites did legitimately warn visitors who were infected with the "DNSChanger" malware. That exception to this rule no longer applies.)
Pirated copies or "cracks" of commercial software, no matter where they come from, are unsafe.
Software of any kind downloaded from a BitTorrent or from a Usenet binary newsgroup is unsafe.
Software that purports to help you do something that's illegal or that infringes copyright, such as saving streamed audio or video for reuse without permission, is unsafe. All YouTube "downloaders" are outside the safe harbor, though not all are necessarily harmful.
Software with a corporate brand, such as Adobe Flash Player, must be downloaded directly from the developer’s website. If it comes from any other source, it's unsafe. For instance, if a web page warns you that Flash is out of date, do not follow an offered link to an update. Go to the Adobe website to download it, if you need it at all.
Even signed applications, no matter what the source, should not be trusted if they do something unexpected, such as asking for permission to access your contacts, your location, or the Internet for no obvious reason.
"FREE WI-FI !!!" networks in public places are unsafe unless you can verify that the network is not a trap (which you probably can't.) Even then, do not download any software or transmit any private information while connected to such a network, regardless of where it seems to come from or go to.
6. Java on the Web (not to be confused with JavaScript, to which it's not related, despite the similarity of the names) is a weak point in the security of any system. Java is, among other things, a platform for running complex applications in a web page, on the client. That was always a bad idea, and Java's developers have proven themselves incapable of implementing it without also creating a portal for malware to enter. Past Java exploits are the closest thing there has ever been to a Windows-style virus affecting OS X. Merely loading a page with malicious Java content could be harmful.
Fortunately, client-side Java on the Web is obsolete and mostly extinct. Only a few outmoded sites still use it. Try to hasten the process of extinction by avoiding those sites, if you have a choice. Forget about playing games or other non-essential uses of Java.
Java is not included in OS X 10.7 and later. Discrete Java installers are distributed by Apple and by Oracle (the developer of Java.) Don't use either one unless you need it. Most people don't. If Java is installed, disable it — not JavaScript — in your browsers.
Regardless of version, experience has shown that Java on the Web can't be trusted. If you must use a Java applet for a task on a specific site, enable Java only for that site in Safari. Never enable Java for a public website that carries third-party advertising. Use it only on well-known, login-protected, secure websites without ads. In Safari 6 or later, you'll see a lock icon in the address bar with the abbreviation "https" when visiting a secure site.
Follow the above guidelines, and you’ll be as safe from malware as you can practically be. The rest of this comment concerns what you should not do to protect yourself.
7. Never install any commercial "anti-virus" or "Internet security" products for the Mac, as they all do more harm than good, if they do any good at all. Any database of known threats is always going to be out of date. Most of the danger is from unknown threats. If you need to be able to detect Windows malware in your files, use one of the free anti-virus products in the Mac App Store — nothing else.
Why shouldn't you use commercial "anti-virus" products?
Their design is predicated on the nonexistent threat that malware may be injected at any time, anywhere in the file system. Malware is downloaded from the network; it doesn't materialize from nowhere.
In order to meet that nonexistent threat, the software modifies or duplicates low-level functions of the operating system, which is a waste of resources and a common cause of instability, bugs, and poor performance.
To recognize malware, the software depends on a database of known threats, which is always at least a day out of date. Most of the real danger comes from highly targeted "zero-day" attacks that are not yet recognized.
By modifying the operating system, the software itself may create weaknesses that could be exploited by malware attackers.
8. An anti-malware product from the App Store, such as "ClamXav," doesn't have these drawbacks. That doesn't mean it's entirely safe. It may report email messages that have "phishing" links in the body, or Windows malware in attachments, as infected files, and offer to delete or move them. Doing so will corrupt the Mail database. The messages should be deleted from within the Mail application.
An anti-virus app is not needed, and should not be relied upon, for protection against OS X malware. It's useful only for detecting Windows malware. Windows malware can't harm you directly (unless, of course, you use Windows.) Just don't pass it on to anyone else.
A Windows malware attachment in email is usually easy to recognize. The file name will often be targeted at people who aren't very bright; for example:
♥♥♥♥♥♥♥♥♥♥♥♥♥♥!!!!!!!H0TBABEZ4U!!!!!!!.AVI♥♥♥♥♥♥♥♥♥♥♥♥♥♥.exe
Anti-virus software may be able to tell you which particular trojan it is, but do you care? In practice, there's seldom a reason to use the software unless an institutional policy requires it.
The ClamXav developer won't try to "upsell" you to a paid version of the product. Other developers may do that. Don't be upsold. For one thing, you should not pay to protect Windows users from the consequences of their choice of computing platform. For another, a paid upgrade from a free app will probably have the disadvantages mentioned in section 7.
9. It seems to be a common belief that the built-in Application Firewall acts as a barrier to infection, or prevents malware from functioning. It does neither. It blocks inbound connections to certain network services you're running, such as file sharing. It's disabled by default and you should leave it that way if you're behind a router on a private home or office network. Activate it only when you're on an untrusted network, for instance a public Wi-Fi hotspot, where you don't want to provide services. Disable any services you don't use in the Sharing preference pane. All are disabled by default.
10. As a Mac user you don't have to live in fear that your computer may be infected every time you install software, read email, or visit a web page. But neither should you assume that you will always be safe from exploitation, no matter what you do. The greatest harm done by security software is precisely its selling point: it makes people feel safe. They may then feel safe enough to take risks from which the software doesn't protect them. Nothing can lessen the need for safe computing practices.
