Message unavailable 10.11.4 Bluetooth upgrade

OK so I installed the 10.11.4 level because it was proposed in the section updates in the app store.

Since then, no Bluetooth, so no keyboard or trackpad, unless I hook them up via brightening cables.

I tried-

1 deleting the Bluetooth plist file and restart with no other connected devices.

2 reset the SMC.

3. the 1 and 2 above

Have had no results so still no bluetooth.

I'm not impressed, for a brand new iMac to fail on an Apple update and, more important still, it has not impressed SWMBO, (one that must be respected), which was anyway anti passage from Windows to Apple. If I lose - no change there then

What else to try? Back to Apple?

You restart just your Mac, or are you stopping and then restart only to have continued problems bluetooth? I have 2 computers here El Capitan 10.11.4 and none missed a beat with Connectivity Bluetooth - with Apple, or third-party products.

  • Messages in the Sierra have not upgraded

    I upgraded to Sierra and my messages app have not improved. It's always the old version with all the names of the contact of my conversations replaced with their phone numbers. If I try and type a name to add a contact on a new message, the application crashes.

    When I look at the modification date of the application in the application folder says 'may 7, 2012', so that all my other wealthy apps goes back to the year underway (2016). I tried to reinstall Sierra again without change.

    Please let me know if anyone knows how to solve this problem.

    Thank you!

    Save a backup copy of your Messages application on a USB key, and then delete the Messages from your Applications folder on your Mac. He may request a username/password admin name. Don't forget to empty the trash after that. Then, try to reinstall the Sierra again and see if that does not copy the new Messages on your Mac application. If something goes wrong, you always have your initial request of Messages and can be replaced from the flash drive.

  • After upgrading to version 9.0.1, I still get a message saying that I need to upgrade. Why?

    When I open Firefox, the message on the screen says I need to upgrade. I have updated and restarted my computer, but the message is still there.

    Change your home page.

    It - http://www.google.com/firefox - is the old Page to start Firefox used by the Firefox 3.6 and earlier versions of Firefox, I do not think that it is maintained by Google.

    From version Firefox 4, Firefox uses a 'local' with the address Start Page of Subject: House. It looks like the old start Page, but this isn't exactly the same thing.

  • Error7 message about the signature unidentified, the upgrade and installation of iTunes 10.5 for Windows Vista.

    Original title: error upgrading and installation of iTunes 10.5 for Windows 6.

    I tried all kinds of ways to solve this problem, but I can't seem to find a solution. This all started when I tried to update my iTunes to version 10.5. Then came the error message 7 on unidentified signature etc. I could not even run my iTunes more then. I started download iTunes again to repair and it just doesn't work. I don't have problems with the installation of my iTunes for the first time a year ago and upgraded whenever I allow it.

    All other methods I tried to correct the error includes:
    • Uninstall iTunes completely and everything that it supports the programs and files (Quicktime, supporter of Mobile, Hello, Safari etc.)
    • Download Quicktime separately after you have uninstalled it as suggested by other users in some forum.
    • Update the frame Microsot.NET as suggested by the Apple Support site.
    • Manually started the installation of such Windows program suggested by one of the answers on this site:

      a. click the Start button, and then type services.msc in the start search box and press ENTER.
      b. Locate the Windows Installer service.
      c. check that the status is started. If the condition column is empty,
      d. right-click on Windows Installer, and then select start.
      e. If you get error trying to force start the Windows Installer service, then try to change the Startup Type to automatic.
      f. restart the computer.

      I have tried for at least 10 times and I have not yet set and am frustrated. Would be really grateful a solution to this soon.

      Windows Version: Windows Vista Home Premium - Version 6.0 (build 6002: Servie Pack 2).

      Thank you.

  • Tell me how to get rid of the pop-up message that happens since I've upgraded to the new Firefox 7

    I've upgraded to Firefox 7.0.1 and whenever I try to open any page I get pop up the following:

     SECURE CONNECTION FAILED
    

    toolbarqueries.Google.com: 443 uses an invalid security certificate.
    The certificate is valid for www.google.com
    (Error code: ssl_error_bad_cert_domain)
    This could be a problem with the configuration of the server, or it could be someone trying to impersonate the server.

    It is annoying and had me "foxed" but I think that you must all find the answer was there on Firefox all the time - UPDATE YOUR FIREFOX. Like Firefox, go to the top left of the screen - you may first need to click on the Firefox icon, but the 'File' through 'Help' options should be located just below anyway. Click on 'Tools', then click on "Options", then select "updates available" - there must be one, click one, and then try to connect on the site of problem once again.
