Should I reinstall OS

My 13-inch Macbook Air mid-2011 is to have a nervous breakdown. Could not connect and determined that it was because the keyboard is stuck on all caps. Use an external keyboard to open a session. Screen acting goofy, Safari crashes sometimes, still stuck on caps. I have reset the SMC. I managed somehow reset the NVRAM, although this was difficult. Even using the external keyboard, it kept taking me to disc utilities. I guess because the change was on the lock, (even with the external)? I was able to reset the NVRAM once, and then, it seemed that everything was fine. Closed the MBA, got it home, opened it, and the plugs have been locked again. You need to use an external keyboard to log, then got the funky screen behavior, etc.

The MBA is not necessary, so I'm open to experimentation. I have never reinstalled an operating system. Think it might be worth?

Start Safe Mode removes the system caches that can help.

Follow these steps to start in safe mode.

  1. Start or restart your Mac.
  2. As soon as you hear the startup tone, hold down the SHIFT key.
  3. Release the SHIFT key when you see the logo Apple appears on the screen.

After the Apple logo appears, this may take longer than usual to reach the login screen or your office. This is because your Mac performs a check of directory of your drive to boot in safe mode.

To leave safe mode, restart your computer without pressing any keys during startup.

  • Why should I reinstall the CD content for first 10 items?

    Hello

    I installed the software Adobe first 10 Elements and Photoshop Elements 10 a WIN7 (x 64) GERMAN

    The content CD is installed, too.

    After some correct initialization of software (start up), we will say I used it 5 times with success, the next launch of first Elements 10 shows

    complain in a popup window:

    "An incomplete set of materials (instant film, title - and menutemplates for example.). has been installed. To install all of the complete content, insert

    your DVD content or download content from the internet.

    You want to install the content now? »

    My only solution is to uninstall the DVD content completely and reinstall!

    That's mean! It will take only 15 minutes to do and certainly isn't a correct behavior!

    I'm running the latest version and checked updates!

    If someone could help me correct this serious fault, I would really appreciate...

    Thank you, Klaus

    Same thing happened for me using Windows 7 64 bit. Given that the content has been installed in Program files (x 86), I moved the content to the folder in Program Files/Adobe first Elements 10. She merged the elements contained in the existing folders. Then I turned off the error message telling me that I had no content. Seems to work fine and I have now everything from loading when I start the program.

  • Should I reinstall InDesign? Problem suddenly.

    Mac G5. Final Tiger. ID CS 3.0.1

    I got this version of ID for a long time and never a problem. Up to now. If I click on the application itself, or on an .indd file, I now get an error message saying ID does not recognize serial number and I need to reinstall.

    Is there a way to get around this?

    I the InDesign CS disc in its case and to the rear is the serial number. I think it's 3.0 not 3.0.1. Is this a problem?

  • iMovie 11 starts to load then goes down, worked fine yesterday.  What's wrong?  Should I reinstall?  I'm in El Capitan

    Just made my first film on iMovie 11 to show the new apple TV.  Worked well started a new project two days ago, but now when I try to open iMovie it starts with 'validation library iMovie on computer' and then seems to load the last project I worked on, (I can see the clips) and then it just stops.  Then the problem page, and even if I select Reopen, the same series of events occurs.  Does anyone know how to fix this?  It is strange that it worked before and I haven't added anything on my Mac.

    You may have a corrupted project.  Try iMovie with the alt (option down key).  This prevents automatically trying to open the last project and may allow you to access other projects or even the problem.

    Many people make problems of running iMovie 11 (= 9 version) State under El Capitan.  I recommend you to consider upgrading to version 10.1

  • to update without permissions, then had to uninstall and reinstall the browser

    I have Firefox setup to inform me of updates, but not really up-to-date without anything to say so. Today, Firefox itself upgrade v37, is crushed, then would not be re - open. After several re-booting my computer I had to uninstall and reinstall the browser and now it the patch v37. If I wanted to auto-update feature I would choose the option for that, but I did not.

    Questions are "why it update when it is not supposed to" and "why he should be reinstalled after it updated itself without permission»

    When the message about an update to Firefox being available, the user has to the [first] see this message, which tends to go behind the main browser window if the user is either click on something to the exact instance dialog box appears. And [2nd] say "not now" immediately, otherwise after that 30 seconds the download will proceed without waiting for a response. It's like this since June 2008 when Firefox 3.0 came out.
