Why does my Mac Book go to a presenters mode when I connect to a projector?

Why does my Mac go into a presenters mode when connected to a projector or system?

But does it then come fully awake? My MB Pro comes on with out of focus screen as if in a fog but once it comes awake it clears up, there is a progress bar at the bottom showing the progress from sleep

  • Why does my mac book pro have a blue screen when booting up for a second just before the login screen

    When turning on my Mac Book pro before it get to the log in screen it has a blue screen for a couple of second the goes to the login sreen. It seams to take some time to complete the login to my computer.
    can anybody give me some help with this problem.
    Thank you

    The cable connections have (so far) solved this problem for my situation. Even though the monitor's DVI cable was firmly connected to the mini Display port connector, when I touched it the attached monitor would go 'blue' or lose its connection entirely. After disconnecting and reconnecting this junction the monitors would still take a hit on touching the connection. I also checked the connection of the mini Display port connection to the graphics board and could not push it in any further. However, after a second go-round I unplugged this connection to the board and reconnected it. I am certain it was fully inserted the first time. But, connection contacts can oxidize over time and sometimes it may just need to be disconnected and reconnected to 're-wipe' the connections. This effectively cleans them at the point of contact. So in my case I'm thinking it was the connection age that was an issue more than a 'loose' connection. Either way, I haven't had this issue for the past two weeks.

  • Why does my Mac Book pro keep restarting

    why does my Mac Book pro keep restarting and how can it be fixed

    It would be nice if you could include a kernel panic log to verify that your problem is...
    Mid-2010 15" MacBook Pros - the bad NVIDIA GPU
    If you're having frequent kernel panics with your 15" mid-2010, or intermittent screen problems, the problem is, more than likely, the faulty NVIDIA GPU found in a number of those machines.
    Here's just a sample of a kernel panic log that points to the faulty NVIDIA card:
    Kernel Extensions in backtrace (with dependencies):
             com.apple.GeForce(6.4.0)@0x82ac4000->0x82b7afff
                dependency: com.apple.NVDAResman(6.4.0)@0x834a0000
                dependency: com.apple.iokit.IONDRVSupport(2.2.1)@0x82fd3000

    Here's the "official" Apple take on the issue - but the very real kernel panics need not be preceded by 'Intermittent black screen or loss of video'... in fact, you might not experience any video problems at all. Although video problems can certainly be a portent of things to come…
    So what can you do? Print out a copy of your kernel panic and a copy of the Knowledge Base article and take them, along with your machine, to your local Apple Store or an Apple Authorized Service Provider. The unfortunate thing is that many people have passed the “three years from date of purchase” now and Apple is not honoring the free logic board replacement for many users. Some dealers seem to be making some exceptions for those past the three year mark, but don’t count on it…
    Good luck,

    Sounds to me like you may have gotten a machine with hardware issues, but it's hard to say.  It will shut down if it gets too hot, but that's not a normal occurrence.  I have never seen a MacBook Pro shut down due to heat, even after lengthy 3D gaming sessions where the fans are running fast and the bottom of the machine is unpleasant to touch.
    First thing I would try to do is reset the SMC.  If that doesn't help, erase the hard drive and reinstall the system from scratch, which you should always do with a used machine anyway.
    If a fresh system doesn't help, you'll need to get it checked out by Apple.
    Edit: Oh, and sig is absolutely right...  please don't post in all caps!  It's very irritating.

    Why does my mac book only freeze at my office and no where else?

    can you be more specific as to when it freezes?  Have you been able to determine a particular pattern as to why it freezes.  Your question is too vague for anyone that does not have access to your office with your mac in the room.

    How about more info so a diagnosis and help can be formulated? Mac model (size), RAM, OS version, age, battery status? What are you doing when it happens? How often? And if you want to be really abundant, pertinent logfiles?

  • Why does my mac book pro screen go black when it goes to sleep and then will not light up again unless I unplug the power cord

    When I either leave my mac book pro open, but idle long enough for it to go to sleep or close the top and put it to sleep, the only way to light up the screen again is to diconnect the mag. connect power cord. Any ideas why and/or how to  correct this problem?

    So this is what I got when I took my computer into the apple store to have it diagnosed.
    After the apple technician performced several tests, the only thing that fixed the issue was an SMC reset. Based on this he figures it is probably a software or firmware issue that is going on. He is a little concerend how ever that the fans of the comupter don't reach maximal rpm when the computer is displaying the issue. So he recorded the problem, and told me to just perform the SMC reset as needed for the next couple months and wait for a new update from apple. If the issue persists I am to go back to the apple store and they will take the appropriate steps.
    He said an SMC reset doesn't hurt the computer in any way, so its safe to do. I am gonna contact blizzard and let them know about the issue as well because if it is software, it could be their game (Diablo 3) that is causing the issue as well. If I hear of anything new i will let you know. So get on the blizzard form and let them know of the issue to fix the problem faster.
    Thanks for your help,

  • HT1349 why does my mac book pro start up but contunitues to try to load

    can someone help with my mac book it starts up logo appeares then the busy signel conuines to try to load but nothing happens?

    Try starting your Mac in Safe Mode.
    Restart your Mac.
    Press and hold down the Shift key immediately after hearing the startup tone. Be sure NOT to press the Shift key before the tone.
    Release the Shift key when you see the Apple logo and the spinning-gear appear.
    When the Login Window appears, log into your account.
    If you Mac starts up, then the issue may be a problem with one of the Startup items, Login items, or a 3rd-party kernal extension (if you got a kernal panic screen during startup.)
    If your Mac does not start up, use the Startup Manager to see if the startup disk is detected. Note: By default the startup disk is Macintosh HD.
    Try running the Apple Hardware Test. This test is included on the Installation CD that came with your Mac.
