Mac book air restart lost all my settings

My mac book restarted itself and now its back to the default settings. All my info is gone. What happened and how do I fix it?

If all your files are missing
You may have logged in as a different user, such as Guest. Open the Users & Groups pane in System Preferences. Your name should be at the top of the user list, under Current User. See also this support article.
If files are missing from one folder
Change the Finder view mode; for example, from icon view to list view, or vice versa.
If files are present, but seem outdated
You may have started up from a different volume (disk.) Open the Startup Disk preference pane and check the selection.

  • I lost my mac book air, i have all my data in a backup disc, but i can´t transfer my address book from that device to mi I Mac.

    I lost my Mac Book Air, and I have all my data backed up in a G-drive slim disc, I'm trying to recover my adress book to the agenda in my I Mac at home,
    but when I'm trying to do that I recieve a message that the vcard's cannot be oppened, because they have a diferent format, what can I do to recover all my telephone numbers and adresses?.

    Hi CJR
    I'm not sure how Time Capsule can be replicated onto your external drive but there is a USB port on the back of TC that can be hooked up to any recent external drive.
    Another thing to think about , besides a Time Capsule failure, is the theft of your Time Capsule, so it might be a good idea to consider separating any redundant back-up from your Time Capsule or both my be stolen.
    TC will back up until full and then begin deleting the oldest back-ups.  Mine is a 2TB Time capsule.
    My back-up plan is as follows:
    1.  Macbook Air back-up on Time Capsule though Time Machine backs up everything - I think it's about every 30 min or so.
    2.  Contacts, reminders, appointments, notes, email are backed up through iCloud.
    3.  iTunes and non-itunes purchased music is on iMatch (and no need to back-up) and any non-iTunes music is backed up on an HP external drive (in case Time Capsule dies)
    4.  Photos are on my MacBook Air and are backed up on my HP external drive.
    5.  Office documents (Excel, Powerpoint, Access etc) are stored in a Skydrive app (like iCloud) and Skydrive syncs these docuemnts with the MS  cloud and my old PC and does not alter their native format like storing in iCloud would do.
    Cheers

  • Can I leave my mac book air plugged in all the time at work, without damaging the battery?

    I know people may have asked this questions many times, however I intend on using my mac book air at work and would like know I I can leave it on powered on in the office and the unplugged at night?. Would it damage my MacBook?

    Yes. It will not damage the battery. You do not need to unplug it at night. If you use it from the AC charage all the time, then about once every two months you should use it on battery power until the battery drops below 20%. Then fully recharge the battery after which you should allow the battery to "rest" for about one hour. It is OK to use the computer during that time but do not yet connect the AC adaptor. Follow this practice and your battery should have a good life.

  • How do I put all my photos and music from my iPhone 4s 64gb to my new mac book air?

    i want to upgrade my phone to the new iphone 5 but i am only going to get a 16gb, i just got a new macbook air and i want to put all my pictures and music from my current iphone 4s 64gb on my new mac book. i am lost on where to start? please help!!

    Ok, normally you would use Apple's Migration Assistant to move all your data from your old computer to your new one but if you don't have access to it, and all your data is only on your phone, you'll have to follow this guide to transfer the data to your iTunes library: Syncing to a "New" Computer or replacing a "crashed" Hard Drive.
    You will read in this guide that iTunes will not transfer music from your phone to your iTunes library if it wasn't purchased from the iTunes store, and that you will have to use 3rd party software such as PhoneView to transfer it.  Also, you can only import photos to your computer that are in your camera roll (by following this guide: http://support.apple.com/kb/HT4083).  If you have photos in other albums such as photo library or photo stream, you will have to use an app like PhotoSync to transfer them to your computer.  You will need to transfer this data to your computer first.
    After transferring your non-purchased music and non-camera roll photos to your computer, follow the steps in the linked guide above exactly as written, being careful to begin by disabling automatic syncing in iTunes, and being sure that you enter at least one contact and on calendar event on your computer, and authorizing your computer for all Apple IDs used to purchase your apps, music and other media (in iTunes>Store>Authorize this Computer) before syncing.
    Your other option is to wait until you have access to the computer you last synced with, and then use Migration Assistant to copy your entire iTunes folder and other data to your new computer, as described here: http://support.apple.com/kb/HT4889.

    You cannot. Your best course of action is to immediately change all your internet passwords, notify the police and your insurance company. Send the remote wipe command to the MBA through iCloud.com and buy a new one from the insurance reimbursement.

  • I just got a new iMac.  I set it up and all of my contacts have disappeared.  They have disappeared on my iPhone and my mac book air as well.  How do I get them back?

    All contacts have disapppeared from my iPhone, my mac book air and my new iMac.  How do I get back.  I assume it has something to with iCloud.  Thank you.

    Use your computer's backup to transfer your iTunes library from your old computer to your new computer per the instructions included with this link, or do the same with both computers networked in some fashion, which shouldn't be hard to do if both computers are connected to the same wireless network.

  • When ACD 30" monitor gets hot, kernel_task utilizes all CPU on Mac Book Air

    I've been having a problem with my system slowing down due to the system "kernel_task" taking over all available CPU (up to 150% of a CPU on my dual core Mac Book Air). I've figured out some of the parameters of the problem, and it seems related to having the Air hooked up to an external monitor:
    1) It seems to only happen when the Air is attached to an external monitor, which in my case is a 30" Cinema Display (which is through a Mini DisplayPort to Dual-Link DVI Adapter -- not sure if this is relevant)
    2) It only happens when the monitor itself is physically warm to the touch (actually the back gets quite hot).
    3) When the kernel_task takes over, and I unplug the Air from the DVI Adapter, kernel_task usually settles down (to 5 - 10% CPU utilization) within 30 - 60 seconds
    4) If I plug the Air back into the DVI adapter at this point (while the monitor is still warm), kernel_task CPU utilization immediately jumps up to 130 - 150%.
    5) If I wait until the monitor is cool before plugging the Air back into the DVI adapter, kernel_task stays in the normal 2 - 10% CPU utilization range for 30 - 90 minutes and the process starts all over again (at this point the monitor is usually quite warm / hot again)
    Rebooting doesn't seem to help (if the monitor is hot, kernel_task starts hogging the CPU right after booting up).
    Has anyone experienced a similar problem? Any thoughts about possible remedies, or ways to further isolate the problem?
    I appreciate your reading this somewhat bizarre tale of woe.
    Thanks,
    Marc

    After upgrading to 10.5.7 this week my MacBook Air goes into kernel_task spin-mode within minutes even when the machine is idle. There are many discussions about this, the longest of which is here: http://discussions.apple.com/thread.jspa?messageID=9458471&#9458471
