HT3500 MacBook Air 2011/ OSX Lion 10.7.2; Epson stylus SX430W Wi-Fi Printer; USB working OK. How to set up wireless connection via USB modem??

Cannot get wireless functions to work, neither via MBA nor Epson setup screen; not IT literate No wifi network available, have I been suckered??

Make a "Genius" appointment at an Apple Store, or go to another authorized service provider.
Apple recommends that you deauthorize a device in the iTunes Store before having it serviced.

    I have a MacBook Air 2011, running Lion 10.7.2, and Safari won't load any pages. Firefox loads everything just fine. What's going on?

    d Pacifist to reinstall both the Safari
    application and the WebKit framework
    was that before the 10.4.6 combo was applied?
    Nope, I tried the Pacifist route after applying the combo update.
    It does sound as if webkit is busted at the moment.
    What version of osx is on your install disks?
    Not sure, I'll have to check them.
    I'd like to avoid a archive & install, but I'm beginning to think it's my only remaining option.

  • MacBook Air 2011 Fan increased after installed mountain lion

    Hi all,
    I have a Macbook Air 2011, Intel core i7. After when I installed ML I noticed that battery go down very fast (about 2:40h) and the Fan speed RPM is about 6500 all time, but I haven't any strong operation pending or App. I have the same app open since lion (Internet, chat, jdownloader) in background (skydrive,evernote,weatherhd) the same app and background task I have with Lion.
    In monitor activity all task is from 1% to 20-30% of usage.
    Any Tips?

    I only have the fan kick in when the graphics is getting hit hard (playing games, driving external displays, etc) with crappy intel on board graphics. 
    Is your MacBook Air in a protective case, skin or having anything block the vent hinge?
    Definitely sounds like the OS thinks it needs to keep running the fan.
    You might try this smart temperature desktop widget and monitor your temperature to see if there is any sane reason for the fans to be on (they are loud!).

  • After installing Mountain lion, macbook air 2011 very slow

    After installation of Mountain lion my macbook air 2011 got very slow. There has been a firmware upgrade too. Can you help?

    Hi guys! Just installed ML on my early 2009 MBAir (after market upgraded to a 240g SSD, but still just 2g of ram), and I panicked a bit at first when it turned out to be painfully slow and not displaying right (+slow trackpad!).
    Bear in mind that the first thing ML will do is index your files for spotlight, which takes a while and is a bit of a resource hog that will slow everything else down and cause your machine to heat up.
    I let it work all night, but by morning, my CPU usage was STILL at 100% and everything slow...
    Activity monitor showed nothing over 10% CPU usage... First tip was to display ALL processes in Activity monitor, and not just MY processes, to see what exactly was sucking up my CPU!
    Then, and it seems to often be the culprit on MBA's, it turned out that the kernel_task process was using up to 170% of my CPU usage (!). Problem is, that process sort of does a million things, so it can be hard to pinpoint the actual issue.
    One of the things it does though, is work against overheating...
    Given the download+install+indexing, my machine had been working all day and night, and was indeed getting super hot. Turning it off and letting it cool down for a whole fixed it all.
    Kernel_task is back to normal, CPU usage is normal, display and trackpad are back to perfect. And in the end, ML is snappier than SL for me, even with the bare minimum in memory!
    Good luck! <3

  • My Macbook Air 2011 got a white screen and a folder with a question mark. I tried to press option+r and try to install the OS X Lion but it didn't show the disk Macintosh Hd

    You are using Snow Leopard so you have no OPTION+R shortcut. You need to boot the computer from your Snow Leopard DVD or USB flash drive.
    Reinstall OS X without erasing the drive
    1. Repair the Hard Drive and Permissions
    Boot from your Snow Leopard Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list.  In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive.  If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer.
    If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
    2. Reinstall Snow Leopard
    If the drive is OK then quit DU and return to the installer.  Proceed with reinstalling OS X.  Note that the Snow Leopard installer will not erase your drive or disturb your files.  After installing a fresh copy of OS X the installer will move your Home folder, third-party applications, support items, and network preferences into the newly installed system.

  • Firmware update on a Macbook Air 2011

    Hello guys, i have a Macbook Air 2011 that had the hard drive damaged, i installed a new one so him only starts on the Utility Page for Reinstall the OSX...

    I can't execute the Firmware update, and without fix the firmware update i can't install the Osx, i also tried to install a new version using the USB Drive Bootable Mountain Lion, but this kinda of Macs Air 2011 only accept a custom Lion OSX, that can be downloaded after the Firmware fix..
    Hope someone can help!
    Thanks

    You replaced the the SSD in a MBA that cannot be user serviced, so that's quite an accomplishment. Your model does not require a firmware update to use Internet Recovery - Computers that can be upgraded to use OS X Internet Recovery. Here's the process you follow:
    Install Mavericks, Lion/Mountain Lion Using Internet Recovery
    Be sure you backup your files to an external drive or second internal drive because the following procedure will remove everything from the hard drive.
    Boot to the Internet Recovery HD:
    Restart the computer and after the chime press and hold down the COMMAND-OPTION- R keys until a globe appears on the screen. Wait patiently - 15-20 minutes - until the Recovery main menu appears.
    Partition and Format the hard drive:
    Select Disk Utility from the main menu and click on the Continue button.
    After DU loads select your newly installed hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Click on the Partition tab in the DU main window.
    Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Click on the Options button, set the partition scheme to GUID then click on the OK button. Set the format type to Mac OS Extended (Journaled.) Click on the Partition button and wait until the process has completed. Quit DU and return to the main menu.
    Reinstall Lion/Mountain Lion. Mavericks: Select Reinstall Lion/Mountain Lion, Mavericks and click on the Install button. Be sure to select the correct drive to use if you have more than one.
    Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.
    This should restore the version of OS X originally pre-installed on the computer.

  • Is there a difference between the USB ports on an imac 2010 and macbook air 2011?

    He has a special keyboard on USB.
    When I connect it to his or my iMac 2010, we need to reboot several times until the KB is recognised.

    Guy would this be of any help:
    To start up your computer in Apple Hardware Test:
    Press the power button to turn on your computer.
    Press and hold the D key before the gray startup screen appears. If Apple Hardware Test does not start up, see the Additional Information section at the end of this article.
    Note: Some Macintosh computers that shipped with OS X Lion support the use of Apple Hardware Test over the Internet. These computers will start up to an Internet-based version of AHT if the hard drive does not contain AHT.  An Internet-enabled connection via Ethernet or Wi-Fi is required to use this feature.
    It takes a minute or so for Apple Hardware Test to start up and inspect your hardware configuration. While this is taking place, an icon appears on the screen:
    When the process is complete, select your language and click the right arrow. If you aren't using a mouse, you can use the up and down arrows to select a language and then press the Return key.
    The Apple Hardware Test console appears. You can choose which sort of test or tests to perform:
    To perform all of the basic tests, click the Test button or press the "T" key or the Return key.
    To perform a more thorough diagnostic test, select the "Perform extended testing" checkbox under the Test button before you click the Test button.
    Your test results will appear in the window in the bottom-right of the console.
    To exit AHT, click Restart or Shut Down at the bottom of the window.

    how can i access to the downloaded data and continue my work
    command+r and option key again straight me on internet recovery
    please help me

    OS X Recovery requries a broadband connection as noted >  OS X Recovery
    There's no need to hold down the Option key to restore OS X.
    Hold down the Command + R keys.
    If your download speeds are less than 10Mbps, you may not be able to restore your Mac using OS X Recovery.
    If you can, take your Mac to an Apple Store > Apple - Find Locations
    In most cases, they will restore OS X for free for you.

  • Time machine crashes macbook air 2011

    Hello,
    I'm using Macbook Air 2011 13 inches and running Lion 10.7.2
    I'm trying to use time machine on an external hard drive.
    But the time machine always crashes the whole computer while I leave the computer unattended for 2 or 3 hours. When I keep using it, it can perform hourly backup without any problem. Once i decide to leave my macbook unattended for over 2 hours, when coming back, the whole system crashes at the stage of backing up 0 KB of XX MB. I put the log below. I have changed the external driver so it is not the external hard disk that generates this problem.

    I understand that Macbook Air 2011 and Mac Mini 2011 uses a pre-installed OS X Lion with a different build number (11A2063).
    However, it seems that with 10.7.2 , there is only 1 build number: 11C74 , as per http://support.apple.com/kb/HT1633 , does it mean that 10.7.2 is a unified version of the OS X Lion for all mac products?
    Therefore, would it be possible to purchase & download the Lion Installer from Mac App Store , extract the InstallESD.dmg and use it as a offline Lion installer for Macbook Air 2011 / Mac mini 2011?
    P.S. I am seeking an offline solution because the recovery partition has been damaged, the internet recovery doesn't work (error 3403F & 4403F), and the recovery disk I have created with http://support.apple.com/kb/dl1433 showed an error "could not find installation information for this machine". And the Apple Authorized Service Providers are charging $150 for a simple restoration of the recovery partition.

    "does it mean that 10.7.2 is a unified version of the OS X Lion for all mac products?"
    Yes.
    "Therefore, would it be possible to purchase & download the Lion Installer from Mac App Store , extract the InstallESD.dmg and use it as a offline Lion installer for Macbook Air 2011 / Mac mini 2011?"
    I don't believe there is a 10.7.2 stand alone installer. 10.7.2 is an update file.

  • How do I connect my MacBook Air 2011 to a projector?

    How do I connect my MacBook Air 2011 to a projector?

    It depends on the input connection for the projector, but since many are rduced resolution, VGA seems to be the prevalent common connection.
    It's just a matter of buying the adapter that adapts VGA to the Mini DisplayPort/Thunderbolt port on your Air. If it is a DVI or HDMI connection input on your projector, the online Apple Store carries that as well.
    This adapter and sufficient length VGA cable is all you need for VGA.
    Here's the DVI adapter.
    For some reason, I am unable to bring up the Moshi HDMI adapter on Apple's site.

    Kindle is connected directly, not thru a hub.  Also called Amazon Kindle support, tech was baffled when I told her I was using a Mac.  She said, "I'm not really familiar with apple products." 
    Precisely why it's not an iPad, and why it doesn't cost very much.  An Apple rep would tell you how to connect an iPad to every computer.

    My MacBook Air has OSX Version 10.9 and suddenly I can no longer access iPhoto. THe message says, 'You can't use this version of the applicaitonn iPhot with this version of OS X.  You have iphoto 9.3.2." When I try to update iPhoto, I get a message saying I signed in with a different apple ID and password.  This all happened about the same time I got a new iphone.  The iPhoto icon has a circle with a line through it.

  • I'm trying to use my older Acrobat 4 for printing files from an older Macintosh with system 9, so that I can store and use the pdf documents in a newer MacBook Air, with OSX 10.9.  Acrobat 4 worked previously but no longer works.  Any way to fix it?

    I am trying to transfer older files from a Mac PowerBook G4, running system 9, printing those documents as pdf, using Acrobat 4.  Then those pdf documents will transfer to my newer MacBook Air, running OSX 10, allowing me to store and use them.  My problem is that Acrobat 4 no longer seems to work on the old Mac, and I don't know how to fix it.  Can anyone give me some suggestions?

    You never know, someone might remember. What happens in detail when you try to use it, and HOW are you trying to use it?
