Why does my mac air always restart when I open it in our university?

Why does my mac air always restart when I open it in our university?
This has been always bothering me for some time already. Whenever I open my macbook air in our university it always warns me to restart my device. When I do the same thing happens over and over again until it reached 27 reports.

I'd make a sound too if i was put into a bag haha.
Only thing i could think of it it has a mind of its own or your putting your computer to sleep. Try shutting down your mac before placing in your bag and see if that changes things.

Because you can purchase an external optical drive like the Apple USB SuperDrive.

I just took in my macbook to the apple store to clean the fan because it was starting make a little noise but instead of making it stop it sounds like an airplane about to take off all the time, it doesn't matter what i'm doing. I dont know what to do now

I just took in my macbook to the apple store to clean the fan because it was starting make a little noise but instead of making it stop it sounds like an airplane about to take off all the time, it doesn't matter what i'm doing. I dont know what to do now? any ideas on how to make it stop?

take it back asap. If it wasn't doing it before they cleaned the fans, they may have accidentally done something that is causing this behavior.

HT1414 why does my iPhone 5s shut down unpredictably and needs to be reset every time to start back up?

why does my iPhone 5s shut down unpredictably and needs to be reset every time to start back up?

Hi Cyprus11,
Thanks for visiting Apple Support Communities.
If your iPhone is shutting down unexpectedly, I recommend going through these troubleshooting steps:
iPhone: Hardware troubleshooting
http://support.apple.com/kb/TS2802
Will not turn on, will not turn on unless connected to power, or unexpected power off
Verify that the Sleep/Wake button functions. If it does not function, inspect it for signs of damage. If the button is damaged or is not functioning when pressed, seek service.
Check if a Liquid Contact Indicator (LCI) is activated or there are signs of corrosion. Learn about LCIs and corrosion.
Connect the iPhone to the iPhone's USB power adapter and let it charge for at least ten minutes.
After at least 30 minutes, if:
The home screen appears: The iPhone should be working. Update to the latest version of iOS if necessary. Continue charging it until it is completely charged and you see this battery icon in the upper-right corner of the screen . Then unplug the phone from power. If it immediately turns off, seek service.
The low-battery image appears, even after the phone has charged for at least 20 minutes: See "iPhone displays the low-battery image and is unresponsive" symptom in this article.
Something other than the Home screen or Low Battery image appears, continue with this article for further troubleshooting steps.
If the iPhone did not turn on, reset it while connected to the iPhone USB power adapter.
If the display turns on, go to step 4.
If the display remains black, go to next step.
Connect the iPhone to a computer and open iTunes. If iTunes recognizes the iPhone and indicates that it is in recovery mode, attempt to restore the iPhone. If the iPhone doesn't appear in iTunes or if you have difficulties in restoring the iPhone, see this article for further assistance.
If restoring the iPhone resolved the issue, go to step 4. If restoring the iPhone did not solve the issue, seek service.
Best,
Jeremy

Why do I have to search for a wifi network most every time I use the internet?

Why do I have to search for a wifi network almost every time I use the internet?
We have Cox internet on a wireless router.
It doesn't seem to be able to hold the wireless connection.....even a couple hours.
The router sits on the desk next to the computer.
Thanks for any suggestions you have.

I don't have any trouble connecting to the internet once I choose our network from the choices.
The computer just can't remember it.

Why does my mac when i try to format my stick say that unable to write to the last block of the device

i bought a new mac with osx lion 10.7.why does my mac when i try to format my transcend 8 gb stick in disk utility say that it is unable to write to the last block of the device?please help me

This may or may not work, but it's worth a try.
Using Disk Utility, try an re-partition the drive into two partitions, making the second partition very small (a megabyte or two), then see if you can format the first partition normally. Leave the second partition alone.
If this works, then the first partiton is what you will use.

I think my mac is infected with a virus, every time I use the internet pop up pages appear constantly what should I do?

I think I may have accidentally opened an email attachment which was fake. Ever since I did this my mac constantly opens pop up pages with ads every time I click the mouse. I have checked in preferences and it says pop up pages are blocked but still they keep appearing. How do I stop this?

You may have installed the "VSearch" trojan, perhaps under a different name. Remove it as follows.
Malware is constantly changing to get around the defenses against it. The instructions in this comment are valid as of now, as far as I know. They won't necessarily be valid in the future. Anyone finding this comment a few days or more after it was posted should look for more recent discussions or start a new one.
Back up all data before proceeding.
Step 1
From the Safari menu bar, select
          Safari ▹ Preferences... ▹ Extensions
Uninstall any extensions you don't know you need, including any that have the word "Spigot," "Trovi," or "Conduit" in the description. If in doubt, uninstall all extensions. Do the equivalent for the Firefox and Chrome browsers, if you use either of those.
Reset the home page and default search engine in all the browsers, if it was changed.
Step 2
Triple-click anywhere in the line below on this page to select it:
/Library/LaunchAgents/com.vsearch.agent.plist
Right-click or control-click the line and select
          Services ▹ Reveal in Finder (or just Reveal)
from the contextual menu.* A folder should open with an item named "com.vsearch.agent.plist" selected. Drag the selected item to the Trash. You may be prompted for your administrator login password.
Repeat with each of these lines:
/Library/LaunchDaemons/com.vsearch.daemon.plist
/Library/LaunchDaemons/com.vsearch.helper.plist
/Library/LaunchDaemons/Jack.plist
Restart the computer and empty the Trash. Then delete the following items in the same way:
/Library/Application Support/VSearch
/Library/PrivilegedHelperTools/Jack
/System/Library/Frameworks/VSearch.framework
~/Library/Internet Plug-Ins/ConduitNPAPIPlugin.plugin
Some of these items may be absent, in which case you'll get a message that the file can't be found. Skip that item and go on to the next one.
The problem may have started when you downloaded and ran an application called "MPlayerX." That's the name of a legitimate free movie player, but the name is also used fraudulently to distribute VSearch. If there is an item with that name in the Applications folder, delete it, and if you wish, replace it with the genuine article from mplayerx.org.
This trojan is often found on illegal websites that traffic in pirated content such as movies. If you, or anyone else who uses the computer, visit such sites and follow prompts to install software, you can expect more of the same, and worse, to follow.
You may be wondering why you didn't get a warning from Gatekeeper about installing software from an unknown developer, as you should have. The reason is that the Internet criminal behind VSearch has a codesigning certificate issued by Apple, which causes Gatekeeper to give the installer a pass. Apple could revoke the certificate, but as of this writing has not done so, even though it's aware of the problem. This failure of oversight has compromised both Gatekeeper and the Developer ID program. You can't rely on Gatekeeper alone to protect you from harmful software.
*If you don't see the contextual menu item, copy the selected text to the Clipboard by pressing the key combination command-C. In the Finder, select
          Go ▹ Go to Folder...
from the menu bar and paste into the box that opens by pressing command-V. You won't see what you pasted because a line break is included. Press return.

Why does my Mac Air keeps logging out and restarting

Can you explain to me why my Mac Air keeps giving me this message? In the middle of a download and I get this when the computer goes into sleep. Once I get this message it will keep trying to log out until finally I log out and then back in again.

From the menu bar, select
 ▹ System Preferences... ▹ Security & Privacy
If there's a closed padlock icon in the lower left corner of the preference pane, click it and enter your login password when prompted.
Click the Advanced button and, in the sheet that opens, uncheck the box marked

Why does my Mac air make a lot of noise with the fan inside?

I bought Mac air one year ago. at the beginning, I satisfied with the product. However, 8 months later, the laptop made a lot of noise from the fan inside. When I I run about 4 or 5 solfwares, it starts warmer and make noise. I feel so unhappy with this. How can I fix it. I bought AppleCare programme for 3 years as well
Thanks

The mid 2011 MacBook Air fans are pretty quiet but not silent and since they are the only mechanical decice you'll hear - there's no hard drive or DVD drive to make noise - it is possible that what you hear is normal. On the other hand, fans can go bad - bearings fail and dust an make the blades become unbalanced. None of us can help - you'll need to take the computer to a repair center or Apple Store and let an Apple repair person determine if the fans need replacing or not. If so, your warranty will cover the cost.

My Mac Air sounds like fan turned on

My computer suddenly started to sound like a fan was on. It got quite loud and was warm.
I am using an external monitor and was on WebEx. I had a PowerPoint loaded, and it was when I was viewing the PowerPoint that this started to happen. I shut off the video from WebEx, and quickly grabbed a flashdrive to back up!
All seems well now.
I've used PP when webconferencing and have never had this happen before.
Thoughts?
D.

Normal
If you only hear it in a quiet room, that is normal.
noisy fan reasons:
A: you notice it more in a quiet room (the typical case) which is normal, all is AOK
B: fuzz and dust has caked onto the blades causing the fan hub to get off balance and make a buzzing sound.
C: fan rotor is going bad and making a whirring or buzz noise (rare).
D: Fan is spinning up due to excess heat from gaming, heavy graphics (typical, all is OK)
A and D are normal
B and C are not.

Why does my Mac Air screen keep flashing white?

I have been having a few issues with my Mac Air. Sometimes, it randomly flashes white/grey (I can still see the programs I have on). It just happens randomly and I'm getting worried....
Can anyone help?
(Please note I am most definatly not Tech Savvey so please try to simplify things if possible_

Make sure that "Screen Flashing" is not turned on.
System Prefernces > Accessibility > "Audio" under Hearing
Uncheck the box beside "Flash the screen when an alert occurs".
