Why is my mac breaking down?
Hi everyone,
I've had this black macbook for over/close to 3 years and I use it on a daily basis so much so that the battery has warped. It is a Intel iCore duo on OS X 10.6.6 (i think i can't check cause it's now decided to stay stuck on the grey mac loading screen) and I have upgrade the RAM to 4gb and use the macbook on a dual screen.
I've previously upgrade from leopard to snow leopard when it first came out it quite recently started to slow down and crash on a very regular basis and so i decided to re-install it and return it to it's previous state with a time machine backup (and this has been done numerous times). It hardly seems to have cured the problem.
The question I am now pondering is it that my time machine backup is the problem so no matter how many times I reinstall snow leopard and restore it using time machine I come back to the same problem? If that is the problem would it just be a question of backing up the files that are essential to me on my hard drive and transferring them back over?
OR
Is it a hardware issue? I have used this computer on a daily basis for 3 years so is it time to bite the bullet and buy a new macbook?
Thanks for your help ahead of time guys and girls!
i have attempted to do the hardware test with extend testing three times now and the computer always shuts down before it can complete it. it only gets as far as testing the memory.
i have managed to do the simple test and it found no problems.

Why does my Mac shut down when using Safari?
Every once in a while (randomly) my mac will reboot due to an error even when I only have the Safari Application open. How can I stop my mac from doing this. I have the 2011 macbook pro 13 inch with the latest OS (Mountain Lion). Everything is up to date but why does it keep shutting down?
Hi Sebaz, first try repairing permissions. Go to Applications-->Utilities-->select Disk Utility. Select your drive then select the First Aid button then at the bottom right click Verify Disk and after it verifies your drive click on Verify Disk Permissions on the left. If there any errors click on Repair Disk Permission. Reboot your machine and test your Safari to see if the issue comes back.

Why does my mac Shuts down intermittently
Why does my mac intel Shuts down intermittently?
Hello veniecy,
Welcome to Apple Support Communities.
This article provides information and troubleshooting tips that will resolve most issues like the one that you’re running into when your iMac shuts down unexpectedly.
OS X: When your computer spontaneously restarts or displays "Your computer restarted because of a problem." - Apple Support

when i play age of empires 3 my mac shuts down for no apparent reason. Any suggestions? 10.6.8 ; 2.8 ghz; i dont know how to find any other info. This did not start until i purchased and installed snow leopard. please help me!
Do an SMC reset, which can fix problems with the system randomly shutting down:
Shut down the computer.
Unplug the computer's power cord.
Wait fifteen seconds.
Attach the computer's power cord.
Wait five seconds, then press the power button to turn on the computer. -
Why is my mac shuts down suddenly
My mac shuts down suddenly, i have to press any botton in oder to turn on, and if I stop messing with the mac it will shutdown. Any advice??
Reinstall OS X without erasing the drive
Do the following:
1. Repair the Hard Drive and Permissions
Boot from your Snow Leopard Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer.
If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
2. Reinstall Snow Leopard
If the drive is OK then quit DU and return to the installer. Proceed with reinstalling OS X. Note that the Snow Leopard installer will not erase your drive or disturb your files. After installing a fresh copy of OS X the installer will move your Home folder, third-party applications, support items, and network preferences into the newly installed system.

Why is Safari/Mac breaking this site?
What can we do to make Safari/Mac view this site without errors?
http://apcinternet.com/edenvale/
Site markup is 100% correct http://validator.w3.org/check?uri=http%3A%2F%2Fapcinternet.com%2Fedenvale%2F&cha rset=%28detect+automatically%29&doctype=Inline&group=0 and works perfectly on Firefox, IE7, IE6, Opera and even Safari/PC - but breaks badly on Safari/Mac.
Any thoughts would be very welcome.
SteveKlaus, from what ulysses69 said above:
We don't have Macs, but our client and some colleagues do.
It's clear he is troubleshooting a problem with the web site when viewed in the Mac version of Safari.
To ulysses69: While clearly many of us are willing to help with this (and I kind of enjoy it, personally), questions like this are probably better suited to other web sites that have forums for general web site testing and troubleshooting. Apple's forums are specifically intended for questions and answers about problems using Apple's products, which isn't really what you're looking for. That said, I don't have a problem continuing in this thread. Just be aware that there are probably more effective places for this kind of question. -
Why did my mac slow down after installing 10.4.11?
I updated from 10.4.9 to 10.4.11. Since then my computer has slowed to a crawl and the spinning beach ball appears every time I click on anything, from attempting to launch Firefox to trying to Force Quit. Is there a way to solve this problem?
General advice on updating:
It is worth noting that it is an extreme rarity for updates to cause upsets to your system, as they have all been extensively beta-tested, but they may well reveal pre-existing ones, particularly those of which you may have been unaware. If you are actually aware of any glitches, make sure they are fixed before proceeding further.
So before you do anything else:
If you can, make a full backup first to an external hard disk. Ideally you should always have a bootable clone of your system that enables you to revert to the previous pre-update state.
Turn off sleep mode for both screen and hard disk.
Disconnect all peripherals except your keyboard and mouse.
1. Repair Permissions (in Disk Utility)
2. Verify the state of your hard disk using Disk Utility. If any faults are reported, restart from your install disk (holding down the C key), go to Disk Utility, and repair your startup disk. Restart again to get back to your startup disk.
At least you can now be reasonably certain that your system does not contain any obvious faults that might cause an update/upgrade to fail.
3. Download the correct version of the COMBO update from the Apple download site. If your car runs on gasoline you would not want to fill the tank with diesel, so don’t try to install the PPC updater on an Intel Mac!
The 10.4.11 Combo Updater for PPC Macs is here: http://support.apple.com/kb/DL170
And for Intel Macs: http://support.apple.com/kb/DL172
If you prefer to download updates via Software Update in the Apple menu (which would ensure that the correct version for your Mac was being downloaded), it is not recommended to allow SU to install major (or even minor) updates automatically. Set Software Update to just download the updater without immediately installing it. There is always the possibility that the combined download and install (which can be a lengthy process) might be interrupted by a power outage or your cat walking across the keyboard, and an interrupted install will almost certainly cause havoc. Once it is downloaded, you can install at a time that suits you. You should make a backup copy of the updater on a CD in case you ever need a reinstall.
Full details about the 10.4.11 update here: http://support.apple.com/kb/TA24901?viewlocale=en_US
More information on using Software Updater here:
http://support.apple.com/kb/TA24901?viewlocale=en_US
Using the Combo updater ensures that all system files changed since the original 10.4.0 are included, and any that may have been missed out or subsequently damaged will be repaired. The Delta updater, although a temptingly smaller download, only takes you from the previous version to the new one, i.e. for example from 10.4.10 to 10.4.11. Software Update will generally download the Delta updater only. The preferable Combo updater needs to be downloaded from Apple's download site.
Now proceed as follows:
4. Close all applications and turn off energy saving and screensaver.
5. Unplug all peripherals except your keyboard and mouse.
6. Install the update/upgrade. Do not under any circumstances interrupt this procedure. Do not do anything else on your computer while it is installing. Be patient.
7. When it ask for a restart to complete the installation, click restart. This can take longer than normal, there are probably thousands of files to overwrite and place in the correct location. Do nothing while this is going on.
8. Once your Mac is awake, repair permissions again, and you should be good to go!
If your Mac seems slightly sluggish or ‘different’, perform a second restart. It can’t hurt and is sometimes efficacious!
9. Open a few of your most used applications and check that all is OK. In this connection please remember that not all manufacturers of third party applications and plug-ins, add-ons, haxies etc, will have had time to do any necessary rewrites to their software to make them compliant with the latest version of your operating system. Give them a weeks or two while you regularly check their websites for updates. This applies particularly to plug-ins for Safari 3.
N.B. Do not attempt to install two different updates at the same time as each may have different routines and requirements. Follow the above recommendations for each update in turn.
Lastly, Apple's own article on the subject of Software Update may also be useful reading:
http://docs.info.apple.com/article.html?artnum=106695
[b]If you are updating Safari (or just have):[/b]
Input Managers from third parties can do as much harm as good. They use a security loophole to reach right into your applications' code and change that code as the application starts up. If you have installed an OS update and Safari is crashing, the very [i]first[/i] thing to do is clear out your InputManagers folders (both in your own Library and in the top-level /Library), log out and log back in, and try again.
So, disable all third party add-ons before updating Safari, as they may not have been updated yet for the new version. Add them back one by one. If something goes awry, remove it again and check on the software manufacturer's website for news of an update to match your version of Safari. Remember: Tiger up to 10.4.10 used Safari 2.0.4 or, if you downloaded it, Safari 3.0.3 beta. Safari 10.4.11 used Safari 3.0.4 which was [i]not[/i] a beta. If Safari 3.1.2 on 10.4.11 is not the fastest browser you have ever used, then something is wrong!
Moreover, trying to revert to Safari 3.0.4 (or worse still, version 2) when running 10.4.11 or 10.5 can have repercussions, as Safari 3.1.1 uses a completely different webkit on which other applications like iChat, Mail and Dashboard Widgets etc also rely, and may entail you having to reinstall an earlier operating system.
[b][i]Most errors reported here after an update are due to an unrepaired or undetected inherent fault in the system, and/or a third party ad-on.[/b][/i] Two such add-on that have been frequently mentioned here for causing such problems are Piclens and Pithhelmet. If you have them, trash them.
Additional tips on software installation here:
http://docs.info.apple.com/article.html?artnum=106692
To reiterate, Input Managers reach right into an application and alter its code. This puts the behavior of the affected application outside the control and responsibility of its developers: a recipe for problems. That's not to say that issues absolutely will ensue as a result of Input Managers, but you, as a user, must decide. If the functionality of a specific Input Manager or set thereof is really important to you, you may well choose to assume the associated risk.
Again, the advice is to remove all Input Managers from the following directories:
/Library/InputManagers
~/Library/InputManagers
especially prior to system updates (they can always be added back one-by-one later). -
My Imac seems to take longer to respond to key strokes than previously. Doe sany one have any ideas why this might be?
First, back up all data immediately, as your boot drive might be failing.
There are a few other possible causes of generalized slow performance that you can rule out easily.
Reset the System Management Controller.
If you have many image or video files on the Desktop with preview icons, move them to another folder.
If applicable, uncheck all boxes in the iCloud preference pane.
Disconnect all non-essential wired peripherals and remove aftermarket expansion cards, if any.
Check your keychains in Keychain Access for excessively duplicated items.
Boot into Recovery mode, launch Disk Utility, and run Repair Disk.
If you're booting from an aftermarket SSD, see whether there's a firmware update for it.
Otherwise, take the steps below when you notice the problem.
Step 1
Launch the Activity Monitor 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 Activity Monitor in the icon grid.
Select the CPU tab of the Activity Monitor window.
Select All Processes from the menu in the toolbar, if not already selected.
Click the heading of the % CPU column in the process table to sort the entries by CPU usage. You may have to click it twice to get the highest value at the top. What is it, and what is the process? Also post the values for % User, % System, and % Idle at the bottom of the window.
Select the System Memory tab. What values are shown in the bottom part of the window for Page outs and Swap used?
Next, select the Disk Activity tab. Post the approximate values shown for Reads in/sec and Writes out/sec (not Reads in and Writes out.)
Step 2
If you have more than one user account, you must be logged in as an administrator to carry out this step.
Launch the Console application in the same way you launched Activity Monitor. Make sure the title of the Console window is All Messages. If it isn't, select All Messages from the SYSTEM LOG QUERIES menu on the left. If you don't see that menu, select
View ▹ Show Log List
from the menu bar.
Select the 50 or so most recent entries in the log. Copy them to the Clipboard (command-C). Paste into a reply to this message (command-V). You're looking for entries at the end of the log, not at the beginning.
When posting a log extract, be selective. Don't post more than is requested.
Please do not indiscriminately dump thousands of lines from the log into this discussion.
Important: Some personal information, such as your name, may appear in the log. Anonymize before posting. That should be easy to do if your extract is not too long. -

Does anyone know why my ATV's (connected to AV & hifi systems) can play music from a computer OK but when I try to use the same computer and library and play them through the same ATV's using Airplay the streaming often breaks down? Although I could live with the current situation I am missing the opportunity for simultaneous multi-zone playing with single volume control via the Remote App on my iPhoneS. Just find it curious as all the elements of the system are the same, ATV's, computer, router etc and would have expected the quality and efficiency to be the same under both modes of operation.
Welcome to the Apple community.
Yes, the quality and efficiency of the audio should be the same for both methods. The fact that it isn't may suggest that you have a problem on your network. Have you checked for interference. -

com.apple.kec.corecrypto 1.0You have the MacBookPro6,2, the Edsel of Macs. You might be able to resolve the problem by reinstalling OS X. Try that first, if you haven't done so already. Otherwise, you may be covered by this program:
MacBook Pro (15-inch, Mid 2010): Intermittent black screen or loss of video
Make a "Genius" appointment at an Apple Store to have the machine tested. The routine hardware diagnostics used by service providers may not detect the fault. There is a specific test for this issue.
Print the first page of the panic report and bring it with you.
Back up all data on the internal drive(s) before you hand over your computer to anyone. If privacy is a concern, erase the data partition(s) with the option to write zeros* (do this only if you have at least two complete, independent backups, and you know how to restore to an empty drive from any of them.) Don’t erase the recovery partition, if present.
*An SSD doesn't need to be zeroed.
You may be able to stop the panics by disabling automatic graphics switching in the Energy Saver preference pane, but that's not a solution. -
Why Wont my mac Mini Shut Down After SSD Install?
Heres the Gist,
I have a late 2009 Mac Mini (A1283) 2.53 GHz, 4gig ram. that i've been running as a media server. Recently the harddrive died in it. I decided to install a Intel 320 Series GEN3 SSD Drive. The install went fine and clean, Mac booted up perfectly, installed a new version of OSX 10.6, no issues, did all the updates. The only software I installed was Plex Media Server (http://www.plexapp.com/) and Google Chrome.
Now my issue is, when i go to shut the Mac Mini down, all that happens is the dock disappears and all the desktop icons then it just sits there, nothing happens. I reset the PMU and it still does the same thing, except now the fan is on high all the time.
Other things i've tried:
Verifiying and Repairing the Disc Permissions
Verifiying and Repairing the Disc
Closing all apps before shut down
disconnecting all network drives and external drives before shut down
reseting the PMU
When I get home im going to try:
Resetting the SMU.
Running YASU (Although its a fresh install with no apps so not to sure what it will find)
Im looking for any and all other suggestions to try. I was considering upgrading to 10.7 to see if its just a software glitch, but im not to sure why this would be happening now.
thanks for any and all advice in advanceIt's SMC > Intel-based Macs: Resetting the System Management Controller (SMC)
