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 13" running 10.7.5 When I click to download Mavericks in the App Store, nothing happens.  What could be the solution?

    There may be no progress bar apparent for Mavericks in the App Store. It may be a bug associated with this particular download.
    To determine if it is actually downloading use Launchpad. You should see a fairly obvious new icon with an associated progress bar. Make sure you check every Launchpad page by swiping left / right.
    If it's paused, click the icon to restart it.
    Once it completes the icon will appear in Applications and Launchpad, it's just easier to find in Launchpad.
    When it's finished downloading it looks like this:
    If it really is not downloading read Mac App Store: How to resume interrupted downloads
    Open the Mac App Store.
    From the Store menu, choose Sign In.
    Enter your Apple ID and password.
    Click Purchases to get to your Purchases Page.
    Click the Resume button next to the app name.

  • Macbook Air 2011 CPU Maxes Out then Overheats and Shuts Down...

    I've been having this problem for a while now but have learned to deal with it with SMC Fan Control to basically keep my fans maxed out at all times. This is obviously not ideal.
    The problem is that at any given time some small, random task in activity monitor shows CPU usage that is very high, often at least 50% CPU and other times as high as 120% It has happened with the tasks like dock, safari web content and virtually any other task you can imagine.
    For example, I just tried emptying my recycling bin and it hung half way through then my computer shut down. What is going on here?
    Details:
    - Macbook Air mid-2011 running Mavericks
    - Never have more than one app open at any given time, usually just Safari with about 5 tabs, max
    - 3rd party applications running in background include Dropbox, Copy, Backblaze, Flux, Sophos anti virus, Jumpcut, Caffeine and that's it
    If I'm doing something like a Time Machine backup, I have to disable Wifi, max out the fans and only then will the Macbook Air remain cool enough to complete the backup, otherwise the Time Machine process maxes out the CPU, overheats and shuts down. This happens with virtually everything now.
    How can I start trouble shooting this problem? I've run the hardware and system repair checks with no results, done an SMC reset, etc.
    This really seems like a software issue more than anything, like something related to the way tasks/processes are handled...any ideas anyone? This is such an annoying problem!

    Do the problems also occur in "Safe Mode"?
    Safe Mode or "Safe Boot" is a troubleshooting mode that bypasses all third party system extensions and loads only required system components. Read about it: Starting up in Safe Mode
    You must disable FileVault before you can start your Mac in Safe Mode.
    Starting your Mac in Safe Mode will take longer than usual, graphics will not render smoothly, audio is disabled on some Macs, and some programs (iTunes for example) may not work at all.
    Merely starting your Mac in Safe Mode is not intended to resolve the problem, it's to observe its performance without certain additional components.
    To end Safe Mode restart your Mac normally. Shutdown will take longer as well.

  • I have a new MacBook Air which keeps turning off by itself and now won't turn on at all...

    It's been working fine since I've had it but yesterday it kept turning off by itself and then within minutes off turning it back on it would do it again. Also the little box kept popping up asking if I wanted to sleep, restart etc as if I had pressed the power button. I tried to turn it off completely and now it won't turn back on at all. If I plug the charger in the green light comes on but nothing happens on the actual MacBook itself. What do i do ?

  • Need help installing CS5 on my Macbook Air i5 with Lion OS?

    I am not sure what I am doing wrong. I am trying to install CS5 on my new i5 macbook air which runs lion. When I connect my external hard drive to install the disc the disc does not even show up on the desktop. I know the drive is fine because I tested it with another disk and the icon show up fine for installation. Not sure what is going on but, guessing it is a conflict with lion. Please help?
    thanks

    I think you would have better luck with an external DVD player/recorder. Have you tried dragging the file from the external hard drive to your desktop and then installing?

  • 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!).

  • 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

    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.

    Do Not post stuff about how Airplay doesnt work, because i dont have Apple TV and dont need to hear about it.

    If you have an external drive equal to or larger than your internal HD, clone your internal to it with either Carbon Copy Cloner or Super Duper. Test the clone to make sure it's bootable. Then upgrade either one. Try it out first.

    Whatever you read was incorrect. You can upgrade directly to Mavericks. It is in the App Store and is free.
    Snow Leopard predates the operating system you already have. That's the reason it will not install on your MacBook Air. You spent $20 needlessly for it, but it's yours to resell if you wish.

  • Is the Macbook Air 2011 able to run the Apple Cinema Display 30" ?

    Hello Everyone.
    So, I am about to buy a Macbook Air 2011 11".
    I want this product because of the ssd driver and the versality of such a light object.
    The things is that i work at school with a laptop, and when i come back home, i use my Apple Cinema Display on my Macbook Pro with the Dual Link dvi Adaptator (which cost me 98€ ouch !! ).
    So i read that there were kind of retro-compatibility between Thunderbolt and Mini-Display Port on the new Mba.
    Is the 2011 mba able to run my external display ?
    Thank  you.
    Nicolas.

    Yes.

  • 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
