Have I not the right firmware?

I have the Macbook Pro 13 inch, late 2011.  I'm on El Capitan.

I've had some strange things happen.  They are usually something of my own making. But today my Macbook pro 13 '' end 2011 Cup twice, then once I had to wait before putting into operation.

I read an article on the EFI and SMC firmware update: https://support.apple.com/en-us/HT201518

I have MBP81.0047.B2a, which seems to be that of three other models (in early 2011)

According to the table, mine is expected to be completed in A2B.  Before I'm going to play with this, am I interpret correctly?  The mid-year change would be quite important?

Read this article. https://support.Apple.com/en-US/HT201518 if you are attempting a firmware update make sure that you follow all the instructions to do so. This problem may have something to do with the firmware. Have you tried a pram reset-command/Option/P/R key and the power button for three chimes at startup? Or reset a SMC.  https://support.Apple.com/en-us/HT201295

  • have I not the right plug ins auto update 38.0.1now very very slow

    yesterday it automatically updated to 38.0.1. It is now very very slow. running win 7 32-bit. tried to update two times, uninstalled and reinstalled without help. plug ins look different and do not know if they are the right ones. also, yesterday I went back to an earlier date and while ms has been updated 26 updates so was firefox. The rest of the system seems ok. Thanks for your help.

    Hi veryslow, please disable graphics hardware acceleration.

    You will have to perhaps restart Firefox for it to take effect, so save any work first (e.g. you compose mail, documents online that you are editing, etc.).

    Then perform the following steps:

    1. Open the Firefox Options tab as follows, click on the menu button

      then select Options.

    2. In the Options of Firefox tab, click Advanced, and then select general.
    3. You will find in the list of parameters, the checkbox use hardware acceleration when available . Uncheck this box.
    4. Now restart Firefox and see if the problems persist.

    This solve your problems? Please report to us!

    Thank you.

  • Have I not the right graphics processor?

    I don't have any of the new features in CS6 creative cloud DOWNLOAD and install.  When I open Photoshop it says that it has detected the graphic material that is not officially supported.

    Is that why I have new features?

    Not sure what you mean. 'New' features such as the non-flou filter come only with PS CC, which is not yet released. Your technical questions have nothing to do with it, but without information system we are unable to help you diagnose the problem.

  • Can I convert a Publisher document to pdf format. I used to be able to do, and now I can't. Have I not the right program?

    How to convert a publisher in pdf file. This program doesn't let me.

    Fix.

    Adobe Reader is a PDF reader.

    Adobe Reader cannot create a PDF file, can not handle the content of a PDF page and can not export the contents of a PDF page.

    To create PDF from the Publisher files buy and install Acrobat. This will install the Adobe PDF virtual printer.

    You can print the PDF using this.

  • all my icons that were normally at the bottom of the screen have migrated to the right side and are all bundled together how to place their return to the bott

    I recently bought a HP 15 laptop with 8.1. I use mainly desktop with latest Mozilla. All my icons that is usually found at the bottom of the screen have migrated to the right side of the screen and boots, to the top, I can't do your choice. I tried to customize without result. I am 75 but strive to keep abreast, but it baffled me.

    Sorry, it's a question of support of Windows, the Windows taskbar does not part of Firefox. I do not use Windows 8.1 myself, and I don't know if the process is the same as on my Windows XP - but maybe click and hold and drag this bar down might work like on Windows XP.

    If you do not understand what I said, or it does not work, here is a popular Windows 8 support forum that should be able to help you.

  • When connecting on MacMini, password is auto-complete with a myriad of points and is not the right password

    When connecting on MacMini after I click on the user, the password field is auto-complete with a myriad of points and is not the right password.

    There suddenly / maybe after the most recent update 2015-008, which I installed it on 8 January 2016.

    I need to delete points, usually I can remove them by double clicking on it and pressing the delete key, but they will not simply remove by clicking in the field and using the delete key, as would be normal. Sometimes it takes a few tries to remove the points, and then I can connect.

    Does my keyboard or a virus, my usb port, the update of security or something else...?

    I use this computer without problem for a few years.

  • Windows 7 Upgrade, saying that it is not the right disc

    I have the HP Windows 7 upgrade CD of 2009 and I'm trying to install it on my genuine HP laptop. First of all, I inserted the CD that is labeled insert everything first. After that everything was checked, I was then asked to insert the upgrade CD, I did, but then I received a notification that the disc I inserted is not the right disk. The CD I'm insertion is the support for Windows 7 Home Premium Upgrade, two CDs have been sent to Microsoft. Is there something I'm missing or is there a way I can work around this problem.

    Looking forward to any help, thank you.

    Note: Running Windows Vista

    Moved from Vista to install, upgrade and activate Forum.

    You try to upgrade to the wrong architecture.

    When important changes to your computer, for example an upgrade, it is always recommended that you back up your system before installing a new version of Windows. In your case, you can upgrade to Windows 7 depending on the edition and the architecture of Windows Vista, you have installed. If you are running a 32-bit version of Vista and upgrade to a 64-bit (Windows 7 edition) version, you'll have a pure make install, it is the opposite case.

    If you are using Windows Vista Home Basic or Premium consumer editions, you can only upgrade to Windows 7 Home Premium or Ultimate. In addition, you can make downgrades, which means, if you are running Windows Vista Ultimate Edition now, you cannot downgrade to Windows 7 Home Premium. You perform logical upgrades:

    Windows Vista Home Basic > Windows 7 Home Basic, Premium or Ultimate

    Windows Vista Edition Home Premium > Windows 7 Home Premium or Ultimate

    Windows Vista Business > Windows 7 Professional, enterprise or ultimate edition

    Windows Vista Business > Windows 7 Enterprise

    Windows Vista Ultimate > Windows 7 Ultimate.

    My PC running the 32-bit version or 64-bit Windows?

  • Could not complete your request because it is not the right kind of document.

    This problem has been occurring for a day now and I honestly have no idea why, I followed the instructions. I've updated my camera raw and photoshop for the latest plugin. I am trying to open an avi file, but it won't open it. Lasts 4 seconds. Usually I was able but yesterday when I tried to open it, it says "Could not complete your request because it is not the right kind of document." Any suggestions because I'm doing the gifs, but I can't because photoshop won't let me open the avi file. file.

    You use file > import > video frames to layers?

  • I want my categories to bookmarks to open on the left, not the right.

    When my favorites opens and I go to a subcategory, they open on the right side of the page and I would like to make them open on the left side of the page. Also, there is a large gap between the subject and the arrow of sub categories, such as about eight inches across the page. They bring closer that sometimes when I move the arrow all the way through to the triangle that comes out the subcategory he shifts to an another subcategory.
    Thanks for your help.

    Who did reduce the width of the page, but it didn't help me find ways make the subtopic open on the left side, not the right as it does now. He did this Fire Fox update itself. Thanks for the initial information if the part worked. Aloha

  • type of product key and he says that's not the right number

    I typed in the product key, but he says that's not the right number.  I checked it several times.  It's a HP Windows Vista Home Premium.

    As HP shipped computers with Windows preinstalled, it is likely that you are using the incorrect product key. The Windows product key is usually in a label in the computer chassis, while the office is usually available to a box or envelope.

  • "not the right kind of document" - eps & ps

    This seems to be a problem with photoshop, as I see it.

    The strange thing is that Photoshop CS2 can open files, EPS and PS, which was very convenient to generate a tiff high-resolution InDesign layouts. Now, suddenly, it cannot open or postscript file - and reads "could not complete your request because it is not the right kind of document.

    I re-installed Photoshop Album CreativeSuite; I also tried to apply the steps from here http://kb2.adobe.com/cps/329/329945.html , but the only "solution" was to recreate the preferences file, which did not help either.

    Clues? Thanks in advance.
