Shutting down Macbook air

HI my new macbook air is shutting down randomly and without notice. is this something from within the computer? or do i have a virus? i just dont know what could be causing this and its new so im kinda freaking out.

Shutting down or just the screen going black? Big difference.
Either logic fault, monitor feed issue if the later. More info needed.
You need to make an appt. for free diagnostic evaluation from your local Apple store.

Text/Code when start and shut down MacBook Air 11.6

I just got a MacBook Air 11.6'' from the Apple store and whenever I start or shutdown, I get code/text appear on the screen for a while. I tried formatting and reinstalling OSx, but it's still there... it reads

Any ideas? I don't want to have to travel 40 miles to swap it at the Apple store.

Looks like its booting in verbose mode.

Lighting bolt port shuts down macbook pro

lighting bolt port shuts down macbook pro once the cable is pugged in. What is the cause of this problem

Hi reginaldt,
If your Mac unexpectedly turns off when you plug in a cable (unclear if you are describing a USB Lightning cable or a Thunderbolt cable) and you have checked to make sure there is no debris in either the cable jack or port, you may want to try resetting the PRAM and SMC:

Yosemite slowing down macbook air performance

Ever since upgrading to yosemite, my 2011 macbook air 11' has been very noticeably sluggish compared to how it was with mavericks. At first i thought it might be from some conflicts from the previous OS, so I did a completely fresh install with yosemite, but it's still dragging and sluggish, especially with any kind of graphics intensive process. I know the air isn't supposed to be a marvel at graphics performance, but I never had these performance issues with mavericks.
Is yosemite just too resource heavy for my macbook air? I wonder if I'd just be better off going back to mavericks. However, if there's some kind of settings I need to adjust, I'd be happy to experiment. I've already tried the 'reduce transparency' trick, but it didn't do much (not that I noticed anyways).

Gatekeeper is described here: OS X: About Gatekeeper - Apple Support. It is only one defense to protect you from inadvertently installing malware, and an effective defense does not rely upon only one method.
... I can use software that isn't officially "identified" by apple, even though it is trusted.
Apple's philosophy is such that a Mac user with Admin privileges always has control over what he or she installs. As I wrote Gatekeeper will serve to protect you against inadvertently installing malware, including the adware that is affecting your Mac. Adware does not get installed on its own - it requires your explicit permission, which you provided by supplying your Admin name and password. When that dialog appears, it should be expected, not a surprise, and its implications should be clearly understood. By providing your credentials OS X concludes you know what you're doing and the reason you're doing it. Determining the "trusted" aspect of software thereby falls to you.
In your case, by choosing the "anywhere" option you effectively circumvented this basic OS X security feature.
The problem with adware is that it relies upon deception to convince you that it's legitimate software offered for some beneficial purpose, when in fact all it will do is interfere with your normal activity and possibly crash your Mac.
Is there anything I can do to possibly identify which apps may be slowing my system down?
Yes, although you installed quite a number of them. For troubleshooting, read below the line that follows the end of this post.
An EtreCheck report generated on a Mac as it ships from Apple will show no entries under Kernel Extensions, Launch Agents, User Launch Agents, Safari Extensions, 3rd Party Preference Panes, etc. Everything that appears under those headings is there because you installed them. As I wrote it's a user's responsibility to understand the specific benefits they are intended to convey, the effects they will have, and the means of uninstalling them should they result in unacceptable performance - which was your original complaint.
It's also possible that the slowdowns are not caused by software, but given the extent to which your system has been modified, hardware failure is less likely than incompatible or poorly implemented software.
... anything that isn't officially "identified" by apple is adware?
Although OS X incorporates specific prohibitions against installing common malware, they can hardly attempt to classify specific user-installed modifications as adware. The only certain way to do that would be to prevent user-installed system modifications altogether, in the same manner as they do with iOS (iPads and iPhones).
Adware's appearance changes approximately every day. Their pathetic developers are desperate to change its appearance in an effort to continue their deceptive tactics, and a simple change of a file name precludes a reliable automated means of intercepting it. That's the reason it's incumbent upon Mac users to educate themselves about its appearance so that they are not so easily gulled into installing some junk. Gatekeeper merely helps you understand that's what you'd be doing.
Back up your Mac if you have not already done so. To learn how to to that read Mac Basics: Time Machine backs up your Mac - Apple Support.
If your Mac is momentarily unresponsive, consider the following.
Launch the Console app - it is in your Utilities folder. You can find it by selecting Utilities from the Finder's Go menu.
If the log list column on the left is not already displayed, show the log list by selecting Show Log List from Console's View menu. Select Show Toolbar if it is not already shown.
Locate system.log in the list and select it. Many date and time-stamped entries will appear, hundreds of them, and you must find the entries relevant to your Mac's problem.
To do that click the Clear Display button in the Toolbar. All previously displayed log entries will be disappear.
Next: Perform whatever actions cause the Mac to exhibit the slow behavior. If the problem is caused by errors logged by the system, the Console window will show them being recorded in system.log.
One or more of them, along with their time stamps, may reveal the reason for the problem you describe.
Copy and paste those log entries in a reply. If hundreds of the same repetitive messages appear, please edit them before posting. There should be no need for more than a few log entries.
Most of the entries will be cryptic but will contain information you might consider personal such as your Mac's name. If you do not want that information to appear, delete or obscure it when posting your reply. Leave enough information so that the entries can be deciphered.

Need to take out battery to shut down MacBook

After installing 10.5.3 my MacBook shows instead of shutting down a small rotating wheel on the screen. I can only stop this by taking out the battery. When I start the MacBook and shut it down immediately whithout using the applications, it works normal. Has anybody an idea?
Thanks.

Hello Thierry,
Parallels is updated and I got rid of the Google stuff.
The kernel shutdown freeze problem occured less often, but it is still existent.
I have Virus barrier since I bought the MB, so far no problems.
I do not understand why Virus barrier could be the origin?
As you suspected already, an additional discussion: "no viruses on a "rootless" Unix system". So far there are no viruses around, but in the future I assume that there will be viruses also for macs.
What do you mean with rootless?
Hello Wolfgang,
I tend to believe that you have a "strong" windows background ... and fear ... Google Desktop ... VirusBarrier ...
"rootless" means that the "root" user is not enable. No one can log in - or attempt to - on your system.
The big difference between Windows and Unix (MacOSX), is that on Windows, there is an Administrator user/group that has full control on the machine. On MacOSX, there is no "root". You are a user who is temporarily allowed to grab root privileges through a grant obtained through a user input.
A virus is a system that penetrates another system and replicates with the objective to infect nearby systems.
On Unix, a virus can modify - and infect - a system only if it runs as owned by root. If your Unix system doesn't have a root user, then that virus program cannot alter root owned files.
The only way for a virus software to gain root privileges is to run as a kernel extension. The command I've made you type is run actually every night on my Mac and sends me a mail with the result.
So, it's not because "one day there will be viruses also for macs". There will never be viruses: they can't replicate! and if there don't they can't be viruses.
Now, there are existing other threats: Vulnerabilities and Trojan Horses.
Vulnerabilities are failures or loop-holes that exists in some software that can allow a system to get past and above the program that presents this exploit and execute its code in the workspace of the application above that has loaded (spawned) the faulty software.
Usually, Virus Protection software databases are updated no faster than Apple or Microsoft, or HP or SUN or IBM when such exploits are revealed to the public (CERT group). Your VirusBarrier won't be of no help here. Just run regularly Software Update.
Trojan Horses are software - malware - that get installed luring the user believing the software in question does wonderful (good) things. Lately, there was a **** site that gave away some video player meant to play **** clips for free. Of course, this was a malware, fooling name resolution and directing browsers to phishing sites. Well, customers to these hoax look like easy preys.
A Virus Checker can help detecting "known" Torjan Horses. But you're not getting to let a TJ come into your system if you're not interested in free ****!!!
A Virus Checker, on the Mac, is only useful to check if you're not going to e-mail to your PC friends an attachment that is in fact a software that uses Windows design flaws to do harm to its owner.
There is no risk on a Mac to browse the web and get a malware, spyware, badware installed inconspicuously.
So, make sure of what software you install on your Mac, where it comes from. Turn off all Sharing services. Turn on Firewall when you're on a network you don't control (Wifi hot spots, hotels, bars, airports). For the rest, you don't risk zip.
Get rid of that Virus Barrier stuff.
When I'm in an airport lounge, I always have fun listening to music of "others" who have left the Sharing on on their iTunes (Macs + PCs). You don't even have to pay for accessing the Hot Spot.
Cheers,
Thierry

Macbook Pro Shuts Down / MacBook Pro Doesn't Start Properly

I just had this problem today. When I tried to wake the macbook pro back from sleep, it didn't wake up, after closing and reopening the screen several times. Thus, I forced quit it by holding the switch button. Now, when I tried to start the macbook pro, the computer automatically shuts down in less than 3 seconds. I have tried resetting the PRAM and all that stuff but they don't seem to work. Has anyone had this issue before?

I am having this exact problem. In my case, I shut down my MBP before going to work. Once I reached work, I tried restarting and it shuts down almost immediately. I've already tried most solutions, but as I am at work, I have not been able to try the cd solution. Any help would be welcome as I do not want to have to reinstall the OS.

Draining battery to 0% shuts down MacBook Pro-10.5.6

On previous laptops and this laptop prior to 10.5.6, when calibrating the battery by letting it drain to 0%, I could immediately reconnect the laptop to the power adapter and then wake it, leaving all of my programs as they were. I was doing this before 10.5.6 and it worked the same way. I just recently, since upgrading to 10.5.6, tried this and the laptop shuts down completely, no sleep. I then have to do a complete power up.
I hope this bug can be fixed as I don't know how I'll ever be able to properly drain the battery to 0% without having to shut down everything on the laptop just as it gets toward zero.
I just confirmed that my 17" MacBook Pro (~1.5 years old) works - it is on 10.5.6, too, so there must be something specific about 10.5.6 and the new late-2008 MacBook Pro's and batteries that's causing the complete shut down.
Has anyone else experienced this or do you have any suggestions on how to improve the situation?
Thanks,

Hello there,
I was experiencing these issues and I do believe I have a solution to this. First, let me explain the process so that everyone understands what's supposed to happen:
When your battery gets too low, the computer is supposed to induce something called "Safe Sleep". Its a lot like Windows Hibernation. On safe-sleep boot, your computer attempts to detect its previous state. When the system detects a hibernated sleep, it attempts to recover that data. If it can't, it leaves safe sleep mode and restarts as normal.
So, it doesn't necessarily have to be your battery that is the culprit, it probably actually is your safe sleep hibernation file that can't be written to for whatever reason.
Here is what you do to fix the problem:
First, navigate and open this file in finder:
/Library/Preferences/SystemConfiguration/com.apple.PowerManagement.plist
When you open this file, Property List Editor should open and you should see the following Hierarchy:
1. Root:
1.1 Active Power Profiles
1.2 Custom Profile
Click the arrow (>) next to Custom Profile.
Now you should see AC Power and Battery Power. You can open either one of those.
You should see an item under those trees called Hibernate File. Take note of this files location. On most computers, it should be located at /var/vm/sleepimage
Quit Property Editor and then switch to finder.
Click Go and then Go To Folder:
In that box, type the directory name: (eg.) /var/vm
Click Ok.
Now you should see a couple of files. You should see the file sleepimage.
Select that file, then click the File Menu and then Get Info.
System should have read and write access.
If all is well there, delete that file. Finder will ask you for an Administrators password.
Once deleted, shutdown your computer.
Then on restart, you will need to perform a PRAM Reset. You can find information on zapping your PRAM here:
http://support.apple.com/kb/HT1379
Once you do that, allow your battery to run down again and it should hibernate properly.

After shutting down MacBook Pro, it will only turn on after changing power outlets

The last few times i have manually shut down my macbook, and attempted to turn it back on several hours later, it wont turn on again. The battery level is fine, I've tried with and without battery connection, and I have reset the PRAM and SMC on the keyboard, but it still wont turn on.
SOLUTION:
The only way it WILL turn on is if I change the charger and move it onto to another powerboard.
It can't be the power outlet as both say that the computer is charging.
It also can't be the power outlet as this has happened at home as well as at uni.
Any ideas why it might be doing this and what I can do about it (other than never turning it off) would be helpful.
The rest of the computer runs fine.

I tried those already, did not work.
I did how ever remove the command key and wiped it down and it turns on perfectly!
but now the keyboard keys seem to be out of place or something. For example it makes a "ping" sound when i hit some of them, when i hit function or control it puts the letter Z.
Any input would be great!

Shutting down macbook pro

The shutting down of my macbook at times is hanging or takes long ever since I upgraded the operating system to Lion. I am forced to hold down the on button for some seconds to shut it down manually. What could be the course of this?

Dear all,
at las I managed to get away with this problem. I found out that I had a problem with one of my RAM.
Now I am lookng at replacing it with a new one soon.
I am using only one 4GB at the moment and the problem is gone and all is workng well now.
Guy who are facing the same problem, better check that your RAM is okay. This could be one of the reasons to your problems.
Thank you all.

Shutting Down Macbook

I've been having trouble recently shutting down my macbook. It's only about a month old. When I try to shut it down, a message pops up saying that it could not close the finder. I've tried to force quit the finder but the only option in the force quit menu is to relaunch the finder. Has anyone else had a similar problem? Also, sometimes after I put in my password to access my computer the screen goes black...
Thanks in advance for your help

You have a corrupted system more than likely. Reinstall OS X:
How to Perform an Archive and Install
An Archive and Install will NOT erase your hard drive, but you must have sufficient free space for a second OS X installation which could be from 3-9 GBs depending upon the version of OS X and selected installation options. The free space requirement is over and above normal free space requirements which should be at least 6-10 GBs. Read all the linked references carefully before proceeding.
1. Be sure to use Disk Utility first to repair the disk before performing the Archive and Install.
Repairing the Hard Drive and Permissions
Boot from your OS X 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 Installer menu (Utilities menu for Tiger.) 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, then quit DU and return to the installer.
If DU reports errors it cannot fix, then you will need Disk Warrior (4.0 for Tiger) and/or TechTool Pro (4.5.2 for Tiger) 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. Do not proceed with an Archive and Install if DU reports errors it cannot fix. In that case use Disk Warrior and/or TechTool Pro to repair the hard drive. If neither can repair the drive, then you will have to erase the drive and reinstall from scratch.
3. Boot from your OS X Installer disc. After the installer loads select your language and click on the Continue button. When you reach the screen to select a destination drive click once on the destination drive then click on the Option button. Select the Archive and Install option. You have an option to preserve users and network preferences. Only select this option if you are sure you have no corrupted files in your user accounts. Otherwise leave this option unchecked. Click on the OK button and continue with the OS X Installation.
4. Upon completion of the Archive and Install you will have a Previous System Folder in the root directory. You should retain the PSF until you are sure you do not need to manually transfer any items from the PSF to your newly installed system.
5. After moving any items you want to keep from the PSF you should delete it. You can back it up if you prefer, but you must delete it from the hard drive.
6. You can now download a Combo Updater directly from Apple's download site to update your new system to the desired version as well as install any security or other updates. You can also do this using Software Update.

Hp v195b flash drive shuts down MacBook Pro when inserted

Hi I hope someone can help me solve this problem.
I bought two hp USB flash drive v195b today and inserted one of them into my Macbook Pro 5,3 with Mac OS X 10.6.8
When I inserted the flash drive a screen turned up in my computer and asked me to shut down my computer on the switch on/off button. This was the only thing the computer reacted to. Nothing else worked.
I then inserted the flash drive in an older macbook with Mac OS X 10.4.11. In this one I could see it and I tried to make a partition using the disc utility tool, but the flash drive still makes my MacBook Pro shut down?
Anyone tried this or have a suggestion to how I solve this?
Thank you, Sanne

Hi sannevils,
With regards to your flash drive, the Beginning Help Guide states for technical support you would need to email [email protected]
Before sending your support request, please include the following in your e-mail:
* Model number of your product (example: v125w or c325w).
Your PC / Notebook DEVICE MANAGER will display the model number of your flash drive.
*Your PC / Notebook system information including Operating System. Be as detailed as possible so that a support agent can do the necessary research before replying to your service request.
*Date of Purchase
*Detailed explanation of the question or issue you are experiencing with the HP USB Flash Drive.
Thank you.

Facetime shuts down MacBook Pro

Did anybody else experience this with Facetime 0.9? It runs for a couple of minutes, then the computer shuts down unexpectedly. I've tried running it on a near fresh install of SnowLeopard on an external drive, but same thing happens.

Hi,
I have the MacBook Pro 1,1 with the 2Ghz Core Duo chip.
Mine was a Built to Order with the Hard Drive change to the larger one (that they had at the time) and the Extra RAM that could be pre-installed (Max 2Gb)
The Drive has a small (20Gb) space given over to Boot Camp and Windows.
I have CS 3, Photoshop Elements 6, TacoHTML, Skitch that I use regularly on there as well as CIV4 (which Distracts me from doing anything that serious on it at the moment). I also have iWork 08 Installed, iMovieHD, iLife and few other things
As EZ Jim has said I can run Facetime and iChat at the same time (in fact see Previews and Complete Video calls on both).
I could call out to EZ Jim's Mac and his Touch without issue from my end.
Accepting calls from EZ Jim's Touch were the problematic connections we tried.
I run Little Snitch which is an Utility which will tell you/Ask for Confirmation for each connection any Incoming or outgoing internet connection an App will make.
I tired turning Off Little Snitch at my end as the Connection was closing the App at the exact point I hit the Allow Button in Little Snitch.
I have 5 Crash Logs. (Home Folder/Library/Logs/Diagnostic Reports)
It is always the Last thread number wise that has Crashed although the actual number does vary.
None seem to implicate Little Snitch from what I can see.
In fact the things listed in the so called Crashed Thread point to things I know work (as in they are the same in successful chats and iChat Video Chats - mostly the Core and viceroy.framework)
My understanding is that as well as 10.6.4 you have to have the relevant Security Update as well
There is a Link to both 2010-006 and 2010-005 in the lower box on the left here http://www.apple.com/support/snowleopard/

Can't shut down MacBook pro

When I try to shut down my MacBook Pro it goes as far as the spinning wheel on the blue screen and will not complete the shutdown. I have to hold the power button to shut down completely.
Both disk and permission repair does not solve the problem.
Did a reinstall of Snow Leopard and still have the same problem.
Help please.

Holding Down Power to shut down Macbook

My Macbook recently wouldn't shut down it just showed the background image on screen but no shut down. So I had to hold the power button for about 8 seconds to shut the computer down. Just curious does that damage the computer in any way or is it safe when necessary? New Mac convert.

No it will not do any physical hard drive damage or any hardware damage.
Do you notice that when you shut down your computer it stays on the background image with a rotating gear that is very faint? You probably did not notice that and thought it was stuck. It is not stuck and will shut down after a minute or so. It is doing necessary maintenance on the drive that should NOT be interrupted. Interrupting that sequence many times will result in a corrupted OS.
As long as you wait 15 seconds for the HD to spin down after holding the power button you will not cause any damage. Of course you don't want to take this as your normal way of shutting down to replace the Apple Menu, Shutdown Option.
Hope this helps,
~ Harris
