Has anyone else seen this/is it normal ?
No, and no. I would make an appointment at the Genius Bar and have it checked out. A full 30-second hang is also not normal. Five or six seconds, I have seen. Thirty? Never.
Easier said than done, nearest Genius Bar is an hour away, also machine is out of warranty. As I said it's been doing it forever, probably plugged it in 300 times. It only has the long hang once every so often. I'll live with it.

  • Macbook Air Immediately powers off when mini display to VGA cable plugged in.

    I have a late 2010 MBA 11 inch. I am runnig OSX Snow Leopard, all software and firmware up to date as of 08/10/2011.
    I am trying to use my mini display port to VGA cable to run an Optoma PK301 projector. Every time I plug in my mini display to VGA cable, the machine immediately powers off. No shutdown screen, no other warning signs, just instant black, as if the power was just immediately disconnected.
    I have tried plugging in the cable while the projector is plugged in and with the projector unplugged. Either way the result is the same. I have been able to start the computer with the adapter plugged in and it will power on, however the projector will no pick up any signal from my MBA.
    Anybody have any ideas on this? I have a genius bar appointment this afternoon. It is just frustrating because I am so used to everything "just working."
    Any help is appreciated.

  • WHY, when I have nothing plugged in does Windows flag up a USB device that is does not recognise?

  • Why won't my MacBook run on battery and display on the monitor?      Runs fine if power cord is plugged in.                                                                                      I have to be plugged in to see the monitor display.  Any ideas

  • Why does my screen turn blue and freeze every time i try to plug in my 'mini display to hdmi' cable into my thunderbolt port in order to use an external monitor?

    why does my screen turn blue and freeze every time i try to plug in my 'mini display to hdmi' cable into my thunderbolt port in order to use an external monitor? it only works if i turn the computer on with it already plugged in.

    Do you have gfxCardStatus installed?  Is your monitor set to "Integrated" or "Discrete".  You want it set to Discrete to drive the external HDMI display.
    Try resetting the PRAM and SMC

    Are you sure you have a good miniDisplayPort to HDMI cable?
    Do you have another HDMI display you can test against (your neighbor's HDMI capable TV).
    Do you have friend that can test the cable using their Mac and maybe their TV or a monitor that has HDMI input.

  • Why I dont have facetime to my ipad mini

    Why I dont have facetime to my ipad mini

    Facetime is banned in certain middle eastern countries.  Devices purchased in those countries cannot have Facetime installed on them by Government Regulation.
    While the device may have been purchased in Kuwait its possible it was destined for sale in another country where facetime is banned.

  • HT201485 why do I have to enter my Apple ID and Password several times each time I launch iTunes

    Why do I have to enter my Apple ID and password several times to enable automatic downloads each time I launch iTunes? I get no password errors.
    I've also notice that some secure websites, e.g., banks, tell me each time I log on to them  that they don't recognize my computer. I don't know if that's related.
    I use two different wifi networks each day, one work, one home
    I am using OS X 10.10.1 on a macbook pro retina, mid 2012
    2.6 ghz core i7 8GB,
    iTunes 12.0.1.26

    That seems strange. Try an iPad reset and see if this fixes the problem,
    Reset your iPad by pressing the 'Sleep' and 'Home' button at the same time for about 15 seconds or so. Your iPad  will then go through a reset / reboot procedure and will be ready for use within about a minute.
    Don't worry about doing this as you will not lose data or settings.
    Good luck and do report back.

  • Why do I have 7 Plug-In files for Quick Time

               I have 7 Quick Time plug-in files, some appear to be duplicates....do I need them all or can I delete the copys?

    Best not to delete any. Seven sounds right, from memory. Different plugins handle different file formats in Firefox, Chrome, safari and other non-ActiveX-based browsers.

  • Do I have to plug my ipad mini directly into the mains for a reliable charge?

    I've been having an issue with my new ipad mini not charging even when its plugged in using the mains adapter unless I plug it directly into the wall. This is a bit inconvienient as I don't have enough sockets and I like to use my ipad as a clock radio with TuneIn so when I wake up my battery is about 40% even though its been plugged in overnight.

    This is unclear and confusing...

    iPad Charging
    "The fastest way to charge your iPad is with the included USB Power Adapter.
    iPad will also charge, although more slowly, when attached to a computer with a high-power USB port (many recent Mac computers) or with an iPhone Power Adapter.
    When attached to a computer via a standard USB port (most PCs or older Mac computers) iPad will charge, but only when it's in sleep mode.
    Make sure your computer is on while charging iPad via USB. If iPad is connected to a computer that’s turned off or is in sleep or standby mode, the iPad battery will continue to drain."

  • I have a macbook pro with lion os. and i want to connect it to my optoma dlp projector. when i connect through a mini display to vga adapter in MBP it detects as OPTOMA XGA but no image on the screen.

    i have a macbook pro. i want to connect it to projector and i have a minidisplay to vga adapter. i could connect my MBP to benq projector successfully and for  all other displays( Monitors). but when i connect it to optoma projector, MBP detects the display as OPTOMA XGA but nothing on bigger screen. i tried changing the resolution and refresh rate also but no changes.
    In my office we got benq projectors , for that it is working very well.(plug and play).
    and also i want to say that there is no problem with the optoma projector seems, because all other windows laptops are working well with that.
    i was struggling with this since one month. i googled it could not find anything supportive for my problem. please help me regarding this. i am new to apple. i hope there must be genius around here.

    I need to know which MacBook Pro you have.  Only mid-2010  and later MBP's transmit sound through MiniDisplay Port to HDMI.  I have no information about the Mac Pro, so you might want to go to that Forum and ask there.

  • I have a macbook pro, a mini display port to hdmi cable to hook up to my tv (a toshiba 1080p flatscreen).  what do I do to actually get the image on the tv screen?  Do I need another cable for sound?

    I am trying to watch a tv show that I purchased into I-tunes.  I have the cable and it hooks to the TV okay.  The TV shows the regular apple screen that looks like the universe screen - like when it boots up or is doing an upgrade on the OS.  I can't get the image to go from the laptop to the TV.  I tried under displays and it shows the TV as a display but I can't get the image on the TV.......Please help.

  • Mini Display Port behaving badly. Anyone else have this problem?

    I have had an ongoing issue with a mini display to VGA adapter, every time I plug it in it becomes erratic over the course of use. It will lose signal and send the monitor blank if I go to remove any of the usb peripherals in the back of the unit. I have returned the unit to Apple 2x now and they have replaced the logic board 2x and the mini display to VGA adapter, yet this is still happening.
    I have tried it with different monitors and cables etc, but this is still going on.
    Is a mini DVI to VGA any more reliable?
    Has anyone else had this issue

    Thanks for the suggestion , but after an extensive talk with tech support and running through the usual troubleshooting regime we came to the conclusion that the best thing for all concerned is that Apple send me a mini DVI-VGA adapter. I am cool with that. No matter what combination of adapters and cables and monitors I plugged the mini into I kept coming up with the same results and my local guys had the same thing happen.
    Thanks anyway.

  • Do I have a mini display port?

    Hello - would anyone be able to confirm if I have a mini display port? I think I only have Thunderbolt but am really not sure, am clearly quite silly!
    Would appreciate help. I have an iMac which I bought in Sept 2011 and it uses Mac OS X......but you will already know this. Oh, and it is 21"
    Thanks
    Pandora

    Okay - I have a feeling that the mini display and thunderbolt port are the same??
