My Macbook Air loses its Mac OS.

I've reinstalled from backup, it lost the system in two days, reinstalled and made a clean install, it lost the system in a week. What can I do? Is it a hardware or a software problem?
Thanks in advance

In one instance the gray screen with apple logo continues to turn but couldn't booth the system. When I made a hard disc check it showed io error for the partition of Mac osx. Now I can booth with windows in another partition but not Mac osx.

  • How can I back up a MacBook Air on a Mac Pro Hard Drive using Time Machine?

    Want to back up a MacBook Air on a Mac Pro with a spare hard drive. Sharing allows Time Machine to find the hard drive, but get a drive busy message when time machine tries to back up onto the drive.
    Any suggestions?

    If you have more than one user account, these instructions must be carried out as an administrator.
    Launch the Console application in any of the following ways:
    ☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
    ☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
    ☞ Open LaunchPad. Click Utilities, then Console in the icon grid.
    Make sure the title of the Console window is All Messages. If it isn't, select All Messages from the SYSTEM LOG QUERIES menu on the left. If you don't see that menu, select
    View ▹ Show Log List
    from the menu bar.
    Enter the word "Starting" (without the quotes) in the String Matching text field. You should now see log messages with the words "Starting * backup," where * represents any of the words "automatic," "manual," or "standard." Note the timestamp of the last such message that corresponds to a failed backup. Now
    CLEAR THE WORD "Starting" FROM THE TEXT FIELD
    so that all messages are showning, and scroll back in the log to the time you noted. Select the messages timestamped from then until the end of the backup, or the end of the log if that's not clear. Copy them (command-C) to the Clipboard. Paste (command-V) into a reply to this message.
    If all you see are messages that contain the word "Starting," you didn't clear the text field.
    If there are runs of repeated messages, post only one example of each. Don't post many repetitions of the same message.
    When posting a log extract, be selective. Don't post more than is requested.
    Please do not indiscriminately dump thousands of lines from the log into this discussion.
    Some personal information, such as the names of your files, may be included — anonymize before posting.

  • Macbook Air loses connectivity every time it sleeps.

    For about a month now my Macbook Air loses connectivity to wifi whenever it goes to sleep. I have it connected to my personal wifi and when I leave the MBA idle it goes to sleep after 15 mins. When I wake the computer it is still connected to my wifi, but the connectivity is gone. I have to turn airport off and then turn it back on. It regains connectivity immediately after that every time. However, it obviously shouldn't do that and it is annoying because it interrupts my downloads. I have tried playing around with the settings and reading the discussion boards. While people have had similar issues, none have been exactly the same and none of the troubleshooting has worked. Wanted to see if anyone had any suggestions or fixes for this. Thanks in advance!

    Hello BrettG81,
    I know that can be frustrating when your MacBook Air does not maintain a Wi-Fi connection. There are a few things that you can try to get it working again. I know you have done some looking at your settings and possibly some adjustments, but go over the first article as some of the troubleshooting for OS X Snow Leopard and Lion can be helpful. Another troubleshooting option is to create a new network location and test it out to see if you still have the same issue. All the steps are linked below.

  • How do I restore my 2011 MacBook Air to its original settings?

    How do I restore my 2011 MacBook Air to its original settings for resale?  When I do the cmd R and go through the process, it begins the restore process for Mountain Lion because I upgraded to Mountain Liion on this machine a few months ago.  And it's asking for my Apple ID.  If I do that upgrade, the buyer will have a version of Mountain Lion that is associated with my Apple ID and that won't work.  Also, isn't there licensing issues in such a case?  I want to restore the MacBook Air to its original factory settings when I purchased it in April of 2011.  At that time it was Lion and not Mountian Lion.  And I don't want any software on this computer to be associated with my Apple ID.
    Thanks for all your help.
    Ron

    Press Command, Option and R keys on boot, open Disk Utility, erase your disk and reinstall Lion

  • Sync workflow between MacBook Air and another Mac

    I'm curious how people with two Macs keep their MacBook Air and other Mac in sync with each other. For example, how do you keep Address Book, iCal, and the word processing documents in sync so that you don't end up with multiple versions across two computers or the wrong data.

    I don't know if the way I do it is the most efficient way, as I posted a similar question here once and didn't get replies. For regular files / documents, I put my MBA on the desk next to MBPro and enable "file sharing" on both computers, then with the Air I click on the shared computer name listed in the Finder, in my case lt lists Mac Book Pro and then all the files from the Pro ore shown on my Air and I can just drag and drop onto my Air desktop. Once I click out of the shared computer, I then drag that file to wherever I want it.
    As far as ICal and contacts, the way I have been doing it is to keep my IPod Touch and the MBPro syncd together with all the iTunes junk and also my calendars and contacts and then at the end of the day I sync those two and then plug the Touch into the Air and it also keeps it updated on calendars and contacts. I would like to learn an easier more direct way but I don't want to buy 3rd party software of mess with .Mac

  • I dont know wether to pick a macbook air or a mac because i want to use it for gaming purposes?

    I want to have a fast computer i can use for school to type papers but i also want it to be fast forgaming as well. Im stuck bewteen the macbook air and the mac desktop computer. Somone please Help.

    Hi, it is dependant on what games it is you would be looking at playing, as to which would suit for those purposes.
    The Latest MacBook Air (If you're looking at the basic model) has an Intel Core i7 Dual Core processor (1.7Ghz), whereas the latest basic iMac, has an Intel Dual Core i5 (2.7Ghz), so when you look at the processor speed and compare them, in theory the iMac would be "faster", when talking about processor speed.
    The MacBook Air ships with an SSD, no matter what spec you order, which would increase speed, however they are quite small for the basic model.
    The MacBook Air, ships with Intel HD 5000 Graphics, and the iMac ships with the nVidia GeForce GT640M 512MB GDDR Memory, and the iMac has many more "Configure to Order" options available, that would allow you to increase the performance of the computer should you want to.
    I can't find the amount of VRAM on the MacBook Air Graphics Card, but based on processor performance, and expandability (RAM Upgrades / HDD Upgrades / Graphics Card Upgrades) I would for gaming recommend the iMac, however there is a large price difference between the two.
    Obviously go and do a bit of comparing on the Apple Website, and read a couple of reviews before deciding, as they all cost quite a lot of money, and you want to make sure you get what you want for your money, so you're probably better reading reviews, as I own neither myself.
    Thanks,
    Ollie.

  • I received an email containing a spreadsheet created using Mac Office 2004 on my new MacBook Air equipped with Mac Office 2011.  When I saved the document, my Finder lists the document without the .xls file extension. Why?

    I received an email containing a spreadsheet created using Mac Office 2004 on my new MacBook Air equipped with Mac Office 2011.  When I saved the document, my Finder lists the document without the .xls file extension. Why?
    All other .xls documents created by Mac Office 2004 retained the .xls file extention when I migrated them over to the new MacBook Air.

    I know what happened.  When I saved the document I somehow hit the Hide File Extension box.  Sorry to trouble this group. I simply resaved it w/o activating the Hide File Extension feature.

  • MacBook Air loses connection to internet but not LAN

    Hi, I am using a MacBook Air 11" (mid-2012) running OS X Mavericks (10.9.3). I'm connecting to my home LAN via WiFi connection to a TP-Link 300M Wireless router that is setup as a switch (per instructions here http://www.tp-link.com/en/article/?faqid=417), which in turn is connected via wire (ethernet-over-power) to a Technicolor cable modem/router provided by my ISP (UPC in the Netherlands; I can look up the model number of the router if needed, but it's two floors down right now and doesn't strike me that this is the cause of the problem).
    I have a problem that my MacBook Air intermittently loses connectivity to the internet for extended periods (minutes) even though (a) the MacBook Air maintains full connectivity to my LAN at the same time through WiFi and (b) other computers connected to the cable modem/router maintain their connection to the internet while my MacBook Air has lost its connection.
    My test to see where the breakdown is occurring is to have four terminal windows up and running ping processes:
    1) ping to 192.168.0.1 (my router) - this always stays live, with essentially no lost packets
    2) ping to an external address (I'm using 74.125.136.94, a google.nl address) - this is my main test for access to the internet and where I see ping failures (I'm also testing with pings to other sites when the problem is occurring to ensure it's not something on the remote end).
    3) ping to 192.168.0.13, which is a Synology NAS attached via ethernet cable to my main cable modem/router - this always stays live, with essentially no lost packets.
    4) a login to the Synology NAS, where I am also running a continual ping to 74.125.136.94, and this external ping does NOT fail when the one from my MacBook Air does, it stays live with essentially no lost packets.
    The problem will usually correct itself after 1-3 minutes (though the time is not consistent), and also gets corrected if I turn the MacBook Air's WiFi off and on again.
    Any suggestions for what I can do to stop this problem?
    Thanks
    John

    No. If connected to WiFI served by Technicolor, the problem does not occur (even if the other AP is connected to the network).
    >     b. can the Technicolor be replaced easily by an Airport Express/Extreme, to repeat this test?
    Unfortunately, Technicolor in router mode is required by my ISP.

    Yes.

    Yes. A Windows machine and several iOS mobile devices work flawlesly for me.

    No. The problem occurs only if connected through additional AP.

    Not yet. I will not have a chance to do it for the next few days though :/

  • How do i get rid of "other" on macbook air? its taking up too much room

    How do I get rid of the "other" storage space on my macbook air? it takes up too much on my small 64GB macbook air? I must get rid of it as I have now space to put anything on my computer.

    For information about the Other category in the Storage display, see this support article. If the Storage display seems to be inaccurate, try rebuilding the Spotlight index.
    Empty the Trash if you haven't already done so. If you use iPhoto, empty its internal Trash first:
    iPhoto ▹ Empty Trash
    Do the same in other applications, such as Aperture, that have an internal Trash feature. Then restart the computer. That will temporarily free up some space.
    According to Apple documentation, you need at least 9 GB of available space on the startup volume (as shown in the Finder Info window) for normal operation. You also need enough space left over to allow for growth of the data. There is little or no performance advantage to having more available space than the minimum Apple recommends. Available storage space that you'll never use is wasted space.
    When Time Machine backs up a portable Mac, some of the free space will be used to make local snapshots, which are backup copies of recently deleted files. The space occupied by local snapshots is reported as available by the Finder, and should be considered as such. In the Storage display of System Information, local snapshots are shown as  Backups. The snapshots are automatically deleted when they expire or when free space falls below a certain level. You ordinarily don't need to, and should not, delete local snapshots yourself. If you followed bad advice to disable local snapshots by running a shell command, you may have ended up with a lot of data in the Other category. Ask for instructions in that case.
    See this support article for some simple ways to free up storage space.
    You can more effectively use a tool such as OmniDiskSweeper (ODS) or GrandPerspective (GP) to explore the volume and find out what's taking up the space. You can also delete files with it, but don't do that unless you're sure that you know what you're deleting and that all data is safely backed up. That means you have multiple backups, not just one. Note that ODS only works with OS X 10.8 or later. If you're running an older OS version, use GP.
    Deleting files inside an iPhoto or Aperture library will corrupt the library. Any changes to a photo library must be made from within the application that created it. The same goes for Mail files.
    Proceed further only if the problem isn't solved by the above steps.
    ODS or GP can't see the whole filesystem when you run it just by double-clicking; it only sees files that you have permission to read. To see everything, you have to run it as root.
    Back up all data now.
    If you have more than one user account, make sure you're logged in as an administrator. The administrator account is the one that was created automatically when you first set up the computer.
    Install the app you downloaded in the Applications folder as usual. Quit it if it's running.
    Triple-click anywhere in the corresponding line of text below on this page to select it, then copy the selected text to the Clipboard by pressing the key combination command-C:
    sudo /Applications/OmniDiskSweeper.app/Contents/MacOS/OmniDiskSweeper
    sudo /Applications/GrandPerspective.app/Contents/MacOS/GrandPerspective
    Launch the built-in Terminal application in any of the following ways:
    Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
    In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
    Open LaunchPad. Click Utilities, then Terminal in the icon grid.
    Paste into the Terminal window by pressing command-V. You'll be prompted for your login password, which won't be displayed when you type it. Type carefully and then press return. You may get a one-time warning to be careful. If you see a message that your username "is not in the sudoers file," then you're not logged in as an administrator.
    The application window will open, eventually showing all files in all folders, sorted by size. It may take a few minutes for the app to finish scanning.
    I don't recommend that you make a habit of doing this. Don't delete anything as root. If something needs to be deleted, make sure you know what it is and how it got there, and then delete it by other, safer, means. When in doubt, leave it alone or ask for guidance.
    When you're done with the app, quit it and also quit Terminal.

  • Which is a better performer, the macbook air or the mac mini?

    Which one performs better, the late 2013 macbook air (standard configuration: 4GB RAM, dual core i5 1,3 Ghz CPU) or the mac mini core quad core i7, 4GB RAM with a regular hard disc?

    LowLuster 
    No Air model can be as fast as a Mini with a quad core i7 CPU. Can't happen.
    I didnt solicit your opinion, and it IS a fact, .....skilled users here on this board will and DO TELL other users OFTEN that:
    "outside of processor core use (video/ photo etc.) you will NOT NOTICE ANY DIFFERENCE on X computer vs. slower Y computer"
    I have a 8 month old QUAD core Mac Mini and it is , as I said above "noticeably not ONE BIT" faster than my current 2013 macbook Air with 8gig.
    My quad core came with 4gig of RAM as I recall, I immediately tossed in 16gig.
    Notice the word "noticeably"
    Your subjective hyperbole aside, you are wrong......., those above yourself and myself (point wise,...as Ogel has stated, Clinton has stated, and others) state this fact very often regarding ---"outside of processor core use (video/ photo etc.) you will NOT NOTICE ANY DIFFERENCE on X computer vs. slower Y computer"
    Its not my opinion, its a fact, namely additionally that I stated "noticeably"   - "my quad core mac mini on MOST EVERYTHING (which is most things since 'most things' are NOT photo and video editing) is not "noticeably" ONE BIT faster than my Macbook Air.
    "most things" people do (most people) on their computer does NOT involve photo and video editing (photoshop pro, final cut pro etc etc)
    This is a fact, that AS SUCH most people WILL NOT notice any difference in general computer use between a quad core mac mini (for example) and a entry level macbook Air. (SSD vs. HD speeds aside).       Nobody is going to notice faster youtube, or Word use, or websurfing, Acrobat Pro, Quicktime play, general APPS that havent changed much in 7 years.
    Dont curse on these family boards please, its uncouth.
    Peace
