MacBook Air "jagged" windows when dragging

This is difficult to describe: when I drag any open window across the desk top, it doesn't move smoothly. There's a minute "lag" which results in the frame of the window becoming slightly jagged. This corrects itself almost immediately, but it is quite noticeable as it makes its way up or down the frame of the window (it depends in which direction the window is being dragged). Not a big deal, but a bit disconcerting on a new machine. The Air is brand new, fully specced.
Does anyone else have this happening?

Thanks for your comment - I've now noticed that this behaviour occurs only when the Air is in "mirror" mode (I have an external Apple monitor), and not when mirroring is turned off. So that seems to rule out a video card problem on the Air?
The "jaggedness" is only a matter of a pixel or two, and it does correct itself once the window has been moved to a new position on the desktop.
PS In mirror mode, the behaviour is seen only on the Air's screen - on the external, it doesn't occur.

A: my MacBook Air becomes unresponsive when logging in, and I decided to reinstall OS X Lion. When running the installer from OS X Recovery, it gave the error message "An error occurred while preparing the installation. Try running this application again."

I encountered the same exact problem when I attempted to re-installed OSX Lion on an old laptop. The date was set back in 2000, which rendered the certificate obsolete. Here's how I fixed it:
From the recovery menu, select the Terminal application. Run the 'date' command to confirm the date is wrong, then set the correct date using this command: date {month}{day}{hour}{minute}{year}
e.g. date 1219195613
Exit terminal (type exit). Retry the installation.

  • My MacBook Air shuts down when its more than half way charged and won't turn on unless I plug it in to the adapter? Why is this happening and how can I fix it?

    If you really do have a Mid 2013 Mac Air model then it is still in warranty, as the standard Apple warranty is one year from date of purchase. So take it into an Apple store and have it diagnosed and fixed under the warranty. There is some type of hardware problem that only Apple can fix.

    Maybe you got mega bucks, but for me throwing money at at Thunderbird drive is STUPID.
    How many times a day are you cloning your 200GB drive?   Must be several times a day.
    I'm all for getting the fastest computer with the most HP, but for backup money I'm going with USB external drive. I probably should state that I run my Time Machine about once a week.

  • Hello, I was going to have my presentation on my macbook air. But when I putted it up on the big screen it wasn't a normal presentation. There was two pages at the time and a timer came up. How can I fix this as fast as posible? Thank's in advance.

    Your MacBook is using the big screen as the Presenter Display, and the MacBook Air display as the Show display. Tap the 'x' key to swap them during the show.
    Here is more information about using the Presenter Display.

    I have an old dell desktop and an older ipod with my itunes library....the dell desktop is not functioning as well and have not been able to sync a newer ipod to the library .....i now have a newer Macbook air....i would like to put my library on my Air i tunes....when i attached the ipod to the air to try to sync the ipod library onto the air itunes i received a message that said i was synced with another library and that if i wanted to sync with this library i would need to "erase and sync" ....got spooked as i dont want to lose the library/ or the music....question ----will this procedure put my existing library (which is all on my older ipod) onto my Macbook air itunes?...any help would be greatly appreciated...thank you in advance...

    No, it will sync the ipod to the content of the MBA which presumably has nothing on it (= erasing content of iPod and replacing it with nothing).

    Quick answer if you let iTunes manage your music:  Copy the entire iTunes folder (and in doing so all its subfolders and files) intact to the other drive.  Start iTunes with the option key held down and guide it to the new location of the library.

  • How to sync MacBook Air with Windows desktop

    I have a MacBook Air and I would like have syncronized my documents, photos, movies, calendar, contacts with my windows desktop. I have Itunes installed in both machines. Why is not possible make MacBook Air does the same my IPAD does with my desktop?

    Welcome to Apple Discussions
    If you mean "How do I mange e-mail and/or files between two or more devices"? You have to get organized.
    If you have POP3 mail it's somewhat complicated: you set your "traveling machine" to receive (but not remove from the e-mail server) new messages. Realize that if you reply from the traveling machine that message will not show up anyplace but the sent box of the machine from which you sent the reply (you can export/import sent messages via a jump/thumb drive back to the desktop when you cease traveling). If you delete a message from the traveling machine you may/or may not have it also deleted from the e-mail server. All those choices or options are sent in e-mail behavior or options (what it's called/where its found depends on your choice of e-mail client)
    The desktop machine is set to download messages from the server. When you are traveling the e-mail client must not be started or running (or you may miss messages on your traveling machine because they were downloaded at home before you turned on your traveling e-mail). Once get home you start your e-mail download all messages still left on the server - delete duplicates and import your sent messages.
    If you have an IMAP4 e-mail client it's much simpler you set up the traveling machine to leave all the e-mail on the e-mail server. You will see all the "new" messages AND when you get home you can have the Desktop see/download your mail sent from the traveling machine as the traveling machine was acting as a "terminal". Again exactly how you do this depends on your choice of e-mail client.
    For files you would keep a copy (or backup) on iCloud, or you could keep all your work organized in folders that can easily be transferred to jump/thumb drives or accessed through file sharing on your home network.

  • TS3147 connect OS X 10.9.2 macbook air to windows 7 network and share printer (Brother HL-2230) connected via USB to the same network

    Would like to share printer Brother HL-2230 on windows 7 network.  Using Windows 7  "Homegroup" is not an option.
    The printer (HL-2230) is connected via USB to win 7 computer.  Before I updated OS to 10.9.2  it (Macbook air) had  HL-2230 as one of its' priinters and was able to print.  Now a print request hangs on "Hold for authentication".
    I have already reset printer system and re-installed printer x2 - no luck. 
    I have already connected WiFi Epson XP-200 to the Macbook air - runs fine, no problem.
    thx for any help that can lead to the resolution of this problem.
