Hi,

 

I have a brand new Macbook Air OSX V10.8.4. I have hardly used it all; although, my husband used it for the past 2 days when his Macbook crashed. I am afraid that I have malware or spyware on this computer now. My symptoms are: the screen keeps randomly dipping to black, the camera light turned on without me doing anything and finally the date was in Welsh and all my file dates in the finder window were in various languages. I  rebooted and reinstalled OS X. But still the language was foreign, so I switched back to English...but Welsh and Vietnamese were definitely checked on somehow in the language settings. What should I do? Is this something I can fix (as a tech novice) or is it a trip to the Genuis Bar?

 

Thanks!


MacBook Air (13-inch Mid 2013), OS X Mountain Lion (10.8.4)

    Seriously doubt it's a malware spyware issue.

     

    English is the first in the list in System Preferences > Language & Text > Language?

     

     

    In the Language & Text window select the Input Sources tab.

     

    Make sure United States is selected from the Region pop up menu.

    Thanks! This makes me feel better and it did switch the language. I wonder why it changed in the first place and why the screen continues to go black. It's hard to get work done with all the dips to black.

    Check your  (Apple menu) > System Preferences > Sharing. What, if any, Services are selected?

     

    Since the MacBook Air is brand new, you really ought to avail yourself of Apple's complimentary telephone support: http://www.apple.com/support/contact/

     

    The problems you describe would concern anyone. Have Apple sort it out - it's part of your purchase price.

    The screen should not turn black.

     

    Try Resetting the PRAM

     

    If that doesn't help, try Resetting the System Management Controller (SMC)

     

    If nothing helped, you have 14 days from the date you recevied your Mac for an exchange or a refund just in case.

    Hey all,

     

    MBA 11" i7 8GB 512GB

    OSX Mavericks

     

    Bought in June.

    Start having the problem since 21.10.13 under 10.8.5.

    Upgrade to 10.9, still the problem.

    Clean install 10.9 from USB + iCloud restore, still the problem.

    Clean install 10.9 from USB, still the problem.

    Clean install 10.9 from restore partition + iCloud restore, still the problem.

    Clean install 10.9 from restore partition, still the problem.

     

    The problem, mainly when it's on battery (2-3 times on power cord plugged), the screen goes black, even when nothing is launched except Finder, and I have to press 5 seconds on power button to turn MBA off, turn MBA back on re-log and restore open applications (if they were some).

     

    Appointment is planned tomorrow morning (Monday) at 10:20 at Genius Bar.

     

    Will keep the post updated.

     

    Have a great day.

    Having the same issues here. On my second MacBook Air (2013) replacement. Mavericks didn't fix the issue either.

    Hi All,

     

    Got our new MacBook air just last week - same configuration as discussed above (8gb RAM etc)... tonight is the first night I have experienced this problem - but it's happened 3 times in the last half hour.

     

    Will be keen to hear the outcome aftera visit to the Genius bar.  Just downloaded Office, Maverick etc, would hate to have to start again!

    I demonstrated this behavior at the Apple Store on 11/2/2013 on my machine and in their test environment. It is easy to reproduce and easy to avoid. I've provided details in this thread: https://discussions.apple.com/thread/5475679.

     

    When the display turns off, it goes through three stages: 1. the screen dims, 2. the screen goes black, 3. the keyboard backlight turns off. Tapping the spacebar or swiping the trackpad anytime during stage 1 will reset the timer. Tapping the keyboard or swiping the trackpad during stage 2 will freeze the black screen with the keyboard lit up. Waiting until stage three to tap the spacebar will wake up the display and everything is fine.

     

    There is less than a one-second window between stages 2 and 3 while the screen is black but the keyboard is still fading that touching the input devices will hang the machine.

     

    This can be reproduced on all mid-2013 MBA's, fresh out of the box, running Mountain Lion or Mavericks. Getting a new machine will not fix it, unless they do a hardware upgrade to fix it.

    I think I may have found the reason as to why the screen suddenly goes black...

     

    Its due to the "Hot Corner" functionality. The screen has 4 programable Hot Corners that functions like an additional set of TrackPad gestures. When you move your mouse near one of the four corners the function kicks in. Whether its view Dashboard, Mission Control or PUT DISPLAY TO SLEEP.

     

    The Fix:

    In the DESKTOP & SCREENSAVER folder in the system preferences, click to SCREENSAVER page. At the BOTTOM RIGHT corner is the Hot Corner button. Click that then change all of the hot corners to - (null) or whatever function you want it to be.

     

    Hope that helps.
