Is it possible to force the Macbook to output a VGA signal without EDID

Im an audio visual integrator and I'm constantly running into this issue that if the mac doesn't have EDID present it will not output VGA signal. Quite often we will convert VGA inputs to just RGBHV (or 5BNC) to run to a display or projector. Normally this works fine with most laptops but unfortunately not macs. I've used things like EDID minders in the past to get around this issue but I'm hoping there might be a way to get around this on the software side.

No, the video card cannot be exchanged - you have a pretty decent GPU there; not sure why you'd want to switch it out. You can upgrade the RAM to a maximum of 16GBs. Apple recommends upgrading in matching pairs, so I don't really think I'd try 4GB and 8GB stick.
Both Crucial and OWC have memory available for the new Macs. Both are reputable dealers and know Macs well and I would only buy from these sources (and I would buy Crucial, were it me).
Although your Mac didn't come with a users manual outlining the installation of the additional RAM, you can download the late 2011 model users guide as the models themselves are almost identical.
Good luck - write back with any questions.

  • My Fall 2009 system DVI output to our HDTV doesn't include audio.  Connecting the Macbook headphone output to the TV's RCA plugs works if TV is in AV (PC) mode, but no picture.  DVI to HDMI adapter to TV works fine for picture, but no audio.

    My Fall 2009 model Macbook Pro DVI output apparently doesn't include audion.  Adapting DVI to HDMI works with new LG TV, but doesn't provide sound.  Connecting the Macbook headphone output to the TV's RCA jacks give sound with the TV in AV (PC) mode, but no video.  Is there a fix for this?  Search for a DVI to HDMI adapter that includes a plug for the headphone jack comes up empty, so far.

    DVI has never included audio, sorry.
    There is also no DVI->HDMI adapter including a plug for audio; such thing cannot work without quite a bit of electronic extra effort.
    Instead of much bla-bla, why don't you tell the exact TV model, and we'll try to come up with a solution?
    BTW, no home theater AV receiver present, correct? Sound to come from the TV, correct?

  • Is it possible to force the user to login again when using oauth 2 (implicit grant)

    Hi,
    I'm trying to build an application based on a rest webservice in APEX which is being accessed by a javascript frontend via ORDS. I'm using the "Implicit grant" flow of OAUTH 2.
    When the user is finished with the application, he/she should be able to logout of the application, so another user can login (on the same machine and browser). But, without clearing all cookies, ORDS will automatically give an access token for the previous user, without showing the login screen to allow/deby access to the rest web service.
    (Clearing the cookies is not possible via javascript, since they are httponly)
    I know it is not the "normal" way to use oauth2, but I would like to be able to log-out a user. So how can I force ORDS to show the loginscreen again to give another user the possibility to login?
    Alexander

    You can force the implicit code flow to prompt the user to sign in by including _auth_=force in the approval request query string. To follow the example shown in the developer guide [1]
    change:
    https://server:port/ords/resteasy/oauth2/auth?response_type=token&client_id=CLIENT_IDENTIFIER&state=STATE
    to:
    https://server:port/ords/resteasy/oauth2/auth?response_type=token&client_id=CLIENT_IDENTIFIER&state=STATE&_auth_=force

  • Is is possible to use the MacBook pro as a handsfree for the iPhone?

    Why we cannot control de iPhone using the MacBook pro?.
    It should be very easy, but it is not.
    I even can't pair my MacBook pro with my iPhone, see pic!
    I really do not understand why we can not use the MacBook bluetooth capabilities to make calls, answers calls etc.
    Apple let us use the Mac bluetooth capabilities to use and control our iPhone, it should be easy, also!

    You may think it should be easy, but in reality it is not.  Your MacBook Pro is not a dedicated handsfree headset, and it would take a considerable amount of effort to write the application code to create a program for your MBP to emulate one.  You can find any third party developer you like and convince them to create a Mac App for you which will provide you with a user interface on your Mac, and use Bluetooth to emulate a handsfree headset for your cell phone (it swouldn't even have to be an iPhone) and see just how much they want to charge you for such an application.  You might be surprised to see how high those numbers really are...

  • Is it possible to know the maximum db output of a pair of headphones based on your laptop volume

    Hello all, I just joined the forum on advice from r/audioengineering. I asked this question over there and they thought you would be better to answer.
    My question is fairly straightforward (may not be simple).
    Is there a way to know the maximum db output of a pair of headphones (such as SONY MDR 7506) at a set system output on a macbook pro (for example 4 bars)?
    Ideally I would like to know that the headphones cannot exceed a level (say 75db) no matter what I throw at it. Then I can set the volume level of the mac, and stop worrying about headphone volume for ear damage.
    I produce music on my laptop for hours on end and the volume of the sound can vary widely quickly when different effects and sounds are introduced.
    I know there are headphones that limit the db output, but the limit is too high (usually 95 or 100 db) from what I have seen.
    Thank you for your help (if possible)

    This is a difficult question to answer with any exactness as it depends on a number of factors. Program, test phones sensitivity/resistance...meter response/calibration...etc...
    I just did a quick measurement on a pair of 7506's using a phonic tool with program (classic rock) at ear cup, unweighted. with program approx. -5 bars on the "volume display" was approx. 75db
    With pink noise approx -6 bars about a 75db average (you can subdivide each bar by 4 using shift+option)
    Max w/pink noise 88db.
    This was all sourced from iTunes with the volume on iTunes all the way up.
    Keep in mind this was quick and dirty, but may give you an idea. As I mentioned before there are a ton of variables involved, and this was done quickly.
    Hope this helps you some.
    I should have also mentioned that this is db SPL, and I had the mic in between the cups to iso it from some ambient noise. I don't know if all the machines are alike in output and gain structure.

  • How to install all the drivers for the MacBook with Windows 7 or 8 without the disk from OSX Lion? Where can I find the drivers?

    Guys, a have one big problem..My customer brought me a macbook with windows 7 installed to do a format and reinstallation, but she is no longer the OSX Lion, and do not know how to install the sound drivers, "touchpad", among other drivers, how to solve this? Where can I find the drivers? The MacBook is now with Windows 8 installed.

    Sorry my bad english..
    See is meant. The MacBook has already come for me with Windows 7 installed, checked that it does not have another partition with OSX Lion installed, do not know how the person who did the maintenance before I managed to remove the partition with the Lion, so I can not create a disk or access boot camp because there is no partition Lion and don't own the DVDs of OSX Lion, you understand me?
    There is a boot camp Windows executable? Where do I find, since I poked around and found nothing on ...
    The sound driver is installed, but not working ... and the rest are missing there also, the trackpad also does not work correctly, the right button does not work ... My experience with mac is low, it may be that you do not know how it works correctly the trackpad

  • Using VGA display without EDID possible?

    Hello,
    I plan to buy a Mac mini in the near future but I have a rather specific concern about the display connectivity in advance:
    Is it possible to use an analogue VGA display that doesn't deliver any EDID/DDC ( http://en.wikipedia.org/wiki/EDID ) with the current Mac mini via the Display Port-VGA adapter.
    I'm asking this because a PC with nVidia GF9400 onboard graphics and Windows 7 or Vista immediately turns off the VGA signal when the OS is completely booted.
    I have a MBP (4,1/Early '08) and could use the display in question with the DVI-VGA adapter after manually setting the correct resulution and refresh rate.
    Can I safely assume that the Mac mini's GF 320M behaves the same way with the Display Port-VGA adapter? I don't have any device with a display port output yet so I can't really test it myself.
    There's a concerning customer comment to the Display Port-VGA adapter in the German Apple Online Store stating that this customer couldn't connect a Samsung LCD TV with the adapter.
    Thank you very much for the help!

    Thanks for the tool tip. Seems like the display has EDID after all:

  • Is it possible to power the macbook pro on just the wall charger, without the battery?

    I'd like to be able to not even use the battery on my computer. Is it possible to run it just off of the wall plugin?

    I have a late 08 Macbook Uni,  I wanted to run it without the battery when I first got it since I got used to running my Dell Laptop without batteries to save my battery from dying because of windows bad power management.
    I found out that my macbook runs much slower without the battery.  Can't really tell you why it just does.
    Do remember that Macbooks have a much better power management system than windows.  My Dell Laptop battery didn't even last 3 years before it fully died.
    My late 08 Macbook is way over it's 1000 charge cycle ( i'm at 1067 ) and i'm still getting over 3 hours from my original battery.
    I suggest you leave your battery in.
    Just follow apple's battery care procedure to make your battery last longer - if that's what you're worried about.
    good luck

  • Is it possible to force the implementation of a SAP note?

    Hi guys,
    I am installing SAP CPM, software components CPD 1.0 and PICM 1.0.  During the SAINT installation, I hit an error for both components in the ABAP Generation Phase.  I have found two notes with automatic corrections (1843317 and 2040519) to fix the errors.
    However, when attempting to implement both notes through SNOTE, it shows them as "Cannot be implemented".  I am assuming this is because the software components are not fully installed yet.
    I know that I can get the correction instructions from each note and manually put them in, but one of the notes has 15+ corrections.  Not exactly how I want to spend my day.
    Is there a way to force SNOTE to implement a note that is listed as "cannot be implemented"?  If not, does anyone have a better way to get the corrections applied besides doing each one manually?
    Thanks!
    -Jayson

    Hi,
    Here i would recommend to go for correction instruction instead of searching force implementation of SAP Notes as notes are used to fix bugs under some specific SAP standard codes and affects specific programs even and only recommended if support package still to be provided by SAP.
    Also need to check for the supported releases under SAP notes for performing corrections (strictly based or relevant for mentioned releases.)
    Hope you will understand and will try to avoid any issues by opting any force methods to implement the SAP Notes.

    Gaurav

  • Is it possible to see the Drill down output in the expanded format by default in SSRS reports?

    Hi Guys,
    I have created a drill down report. If i preview my report , by default i can see the out put in the aggregated level and i have to drill  it to down levels if i want. My requirement is i want to see the data in the leaf level by default means report
    should be displayed in the expanded format to the leaf level, if i want i can drill up the report later. 
    Is this possible in SSRS? Can some one help me out on this?
    Thanks in advance.
    Regards,
    kiran

    Hi ,
    Thanks for the reply. but if i follow this steps i can see the output in the expanded format but + and - symbols will be interchanged. That means if i drill up i have (-) before the column name and if i drill down it will be (+). 
    For this to work you need to set properties initial appearance of toggle image

    under www/ there is no *.java file???? only html file???
    Is there anyway somebody in blueprint who just create source zip file like it used to be in 1.3.2?
    with setup.xml and build.xml and link up there? It will say one day work for somebody.
    Also ERROR -

    Also, shows error! at chrome I don't know at iexplorer.
    please try -

    You have to execute the installer jar file.
    This will create a folder with all the source codes inside.
    I wasn't aware of any need for cvs.

  • Is it possible to disable the keyboard on a macbook?

    I have a 13", early 2008 MacBook, running 10.7.5. Does anyone know if it's possible to disable the MacBook's own keyboard when I have a separate keyboard plugged into it? It would really help prevent unintentional typing/deleting/opening of apps etc. by the cat!

    Hello pmacd12 and welcome to Apple Support Communities,
    I can't think of a software solution that wouldn't involve something you wouldn't want to do. A hardware solution would involve disconnecting the top case but that would also disconnect the power switch.
    I think you should make a hard cover to cover the keyboard when you're using it. Aluminum or hard fiberboard would do nicely.
    My cat doesn't bother my keyboard, just whacks me with her tail or puts her paw on my shoulder meaning she wants to be let out!
