  • My MacBook Air won't turn on, despite being fully charged, and plugged into the power jack.  What should I try?

    I double checked the power connection, it's good.  The charge light is green, so it should be charged and turn on, right?  When I push the power button--nothing no startup sounds, nothing on the screen, keys don't light up.  It's completely dead, as if it is powered off.  I don't know if this could be having an effect on it...I upgraded to the latest operating system (Yosemite) a couple of days ago. After that, it wouldn't recognized our Epson WIFI printer.  The printer was visible as an option under print, but when selected there was a message saying it wasn't connected.  Even after going through the steps to add it agaiIn, after printing one document, then trying to print the next, the "printer was not connected" again. I gave up and shut it down for the day. Used it last night without any issues (except for being unable to print.). Now, this morning, nothing.

    I've got Macbook Air 11" (Mid 2013). But it has an issue of taking up some time to be active after it has been inactive for a while (like when i dont use it for a while the macbook autosleeps and then when i want to work on it and try to get it active the screen only shows mouse pointer in a black screen and then the other components like the small window where you enter password and other takes time to appear...)
    plz help...I've been facing this problem for 2 weeks now...and wanna fix it as soon as possible....plz help...

        Hope this helps.

  • Macbook pro 15-inch 2011 vs. MacBook Air 13-inch 2013

    Hello. I currently own a MacBook Pro 15-inch, early 2011 model. It has 8 GB of RAM, a quad-core, 2.3 GHz i7 processor, hi-res, anti-glare display, an AMD 6750m and Intel HD 3000. I bought it off of an Apple product store on Ebay about 3 and a half months ago. It was 1,350$. It was in perfect condition when I bought it, and it still is. I'm really into producing music, and I use Reason 6.5. I also do some other small things on my laptop, like word-processing, web-browsing and I bring it to school everyday. I was wandering if I should sell this laptop on Ebay, and buy a brand-new Macbook Air, 13-inch, 2013 model. The laptop is a little thick and heavy, and its battery-life is nothing compared to the MacBook Air. I really value battery-life I would probably upgrade the RAM to 8 gigs, and maybe upgrade the processor to 1.7 GHz, maybe upgrade the SSD to 256, but I might not. I was wandering if this would be a good idea. How much would I be able to sell this laptop for on Ebay? Is the MacBook Air weaker or stronger than the laptop I am using now? Screen real estate is something that matters a lot when using a music program, which is why I initially went for this laptop. Now, since the MacBook Air is smaller, I know that it displays just as much as this laptop does, so I don't think that the screen size would be that big of a problem. I am thinking about saving up for a 27-inch iMac, which would then be my primary machine, but if I were able to buy one, it wouldn't be for awhile. Anyways, Thanks to anybody who can help me!

    Nice to see you again.
    The macbook Air is 'stronger' than the Pro only in terms of containing MUCH fewer parts, far less to fault, easier to repair
    both have unibody aluminum alloy frames.

    Its stronger in alloy form factor, slim design with only ONE moving part, no HD to crash from mechanical failure of impact etc.
    Ive got an Imac and current Air, and owned several Air, the air is the hands down choice for myself and I wouldnt part with it for any amount of money.  Also own a couple macbook Pro, new and older one i rebuilt.

    Macbook Air:
    Only one moving part, ultrafast boot time SSD, the full power of laptop with the weight of an Ipad (close).
    Air is the only Mac that has Haswell, 802ac wifi, and incredible 12hr. batt life in 13" I5. HOWEVER NOW the new Pro have 802ac wifi
    Recommend buying the Air with 8gig Ram.
    Pack around a regular laptop around about 20 days, then an Air, .....after that the standard laptops stays at home.    
    Only one moving part, the fan. No moving HD heads to crash or moving platters.  Runs a LOT cooler than anything else out there (which = durability).  Heater is a killer on a scale of 10X over that of accidents.
    Also the AIR has far fewer parts to fail inside than a standard laptop.  Really only a few replacement parts
    The speakers on the Air, contrary to what most people would assume, are much louder than on the macbook Pro.
    The Air in general is faster due to the SSD, also if you have a 802ac Router (i.e. Airport Extreme) then the Air over wifi is a LOT faster.
    If youre going to be dragging a notebook around campus all the time, the Air makes things a lot more lovely.
    The FINAL consideration of course is your application USE, and needs regarding same (see specs and video above)
    The new Air, NOW with Mavericks is just 'king of the hill'. Nothing touches it

    Please  help me..

    It is really not relevant what you buy; especially with electronics, your item is "outdated" as soon as you get it home because there will always be a newer, bigger, better things out there.
    Does your machine no longer do what you need it to do? If so, sell it, and buy a new one. If it does what you need, then keep it and work with it.
    Apple allows for returns within the first 14 days; you can try going to a store and seeing if they will make an exception, but I would not expect it.

  • Macbook air 2014 is 2013 mid?

    I bought macbook air in russian apple online store 1 month ago. Now I open settings and see that macbook air is mid 2013...
    Why is that?
    Is it normal?
    < Personal Infromation Edited By Host  >

    Weird - I thought I posted an answer to this already. The i7 model wasn't updated, just the core i5 model so it is indeed a mid 2013 computer.
    It's a bad idea to include personal information - like a computer serial number - in your post. I've asked a moderator to edit the post to remove it.

  • Can I use my Macbook Air 13" mid 2013 with plugging charger even at 100 % battery full charge?

    I can't decide whether using My Macbook Air 13" mid 2013 with charging power adapter connected even though it is fully charged Or using Macbook Air with unplugging charger after fully charged. Please advice me to maintain my Macbook's battery at good condition.

    It will not hurt it as long as you do not leave it on the charger for an extensive period of time (say, days).

  • I bought Macbook Air early 2014. Ever since i bought it to turn it on after a long ie. 5hr - 6hr i have to first charge it for at least 15 mins and sometimes it wont turn on for 3hr - 4hr and then it will turn on regardless of the battery charged.

    I bought Macbook Air early 2014. Ever since i bought it to turn it on after a long ie. 5hr - 6hr i have to first charge it for at least 15 mins and sometimes it wont turn on for 3hr - 4hr and then it will turn on regardless of the battery charged. If i had put it on sleep even then it wont turn on it will work as usual as it is suppose to do. I went to icare twice and they game me the device back after 1-2 weeks saying it is now not giving any issue but when i will used it next morning again same thing happened. It's like i can never go out anywhere with the laptop outside as i have to first charge it and then turn it on. Icare wont replace my device they only say if there is any issue with the hardware we will replace that hardware but i think it is useless because they don't know what the issue is. Can someone help me out what to do now ? It's been to iCare ever since i bought it now i don't want them to again do the same thing.

  • I find the iphone 5s photographs and videos very difficult to copy into my PC after upgrade to ios 7.1.2. Previously I was able to open it in my computer (Windows 8.1 loaded on macbook air 13" July 2013) model, within iphone ikon - DCIM.  Why not now

    After upgrade of my iphone 5s to ios 7.1.2, I am not able to open iphone ikon- Internal Storage-DCIM - in My computer
    The folder is shown as empty
    I use Window 8.1 loaded on my Macbook air 13" July 2013 model
    Should I stop using iphone for photography and use my Canon DSLR
    Taking photo is easy with iphone 5s.  But retreiving the photo/video
    is time consuming and I feel is a waste of time
    Any way out?

    Is your phone unlocked when your importing the pictures.
    This sound more like a window 8 issue.

  • My (UK bought) MacBook Air wont open open Chilean (.cl) websites - anyone any idea why?

    My (UK bought) MacBook Air wont open open Chilean (.cl) websites - anyone know why? Or what I can do to change this?

    Go to the main Library folder and look for a folder called Application Support / Microsoft.
    There are a few folders in there, and you may have to do some digging. In one of them (mine is called MAU2.0), there should be a file called Microsoft Autoupdate. Open it.
    It looks like this:
    check the button for manual updates.
    That should let you open the apps without triggering an automatic update.

    i have just bought macbook air, cant make video calls on skype... why??

    See this thread:
    https://discussions.apple.com/thread/5306216?tstart=0
    FIX: 
    1. You need Time Machine
    2. Go to folder /Library/CoreMediaIO/Plug-Ins/DAL/
    3. Copy AppleCamera.plugin to good place (usb memory stick is the best place).
    4. Go to Time machine in date that skype work fine.
    5. Change AppleCamera.plugin with file from Time Machine
    6. Restart system, Now skype need to work with camera.
    If that doesnt pass,
    Suggest looking here, much success has been found:
