Cannot uncheck Safari preference to "Open 'safe' files after downloading".

The option to open the 'reliable' files after downloading Safari preferences (general tab) is grayed out so that the selection cannot be changed. It is currently enabled, and I want to uncheck.

Running OS - X El Capitan version 10.11.4 on a Macbook of 2015 the retina with 1.1 GHz Intel M Core with 8 GB of DDR3 memory. I applied all the updates that are available. It's a pretty clean machine all other software/applications installed - only the latest version of Microsoft Office, Microsoft Remote Desktop and Symantec's Solutions have been added.

What would make that and more importantly, how do I do if I can check/uncheck?

Remove the test and com.apple.Safari.plist file.

Empty the trash.

Quit all applications.

Hold down the option key and click on the "Go" menu in the Finder menu bar.

Select 'Library' in the menu dropdown.

Library > Preferences > com.apple.Safari.plist

Right-click on it and select "place it in the trash.

Close the Finder window.

Turn it back on.    Restart Safari.

If this does not help, "put back" the com.apple.Safari.plist

Right click on the trash icon in the Dock, then select 'open '.

Right-click on the com.apple.Safari.plist and select 'Put Back'.

If this does ' t solve the problem:

PC Backup.

Reinstall OS X El Capitan 10.11

Reinstall OS X from recovery

  • Error message - Windows cannot open this file after downloading program

    After several days in offline mode, I went online to update Microsoft Security Essentials and click on analysis complete.  It took an hour.  After that, I found that all my programs were virgins, almost of all of the standard microsoft Microsoft Security Essentials is.  I tried to download it again, plus others such as adobe acrobat, but all said "windows cannot open this file".  I asked help from Microsoft but received access denied.  I feel like an illegal immigrant, as all the doors were closed.  What does that mean?  My OS would be illegal?  It is Windows XP and was purchased new in the retail price in 2004 and has only once been out of my hands when I sent it repairs and have 2 GB ram added.  Any ideas?

  • I can't open the file after download

    Im trying to download cs 5 design standard but when I try to open the file, it says cannot open files z, I want the regular exe. file, how can I get that >?

    Normally a download will include an exe file and a file in which you run the exe file and it installs the software from the zip file.

    You can download the demo version of the software through the page linked below and then use your current serial number to activate it.

    Don't forget to follow the steps described in the Note: very important Instructions in the section on the pages of this site download and have cookies turned on in your browser, otherwise the download will not work correctly.

    I just finished installing an upgrade of the LR5 from a DVD.

    After that, I downloaded the last update that I have this case is LR5.6.

    My problem is that I can not extract the files in the upgrade.

    I just got a message from the installer tells me that there is a problem of extracting some files and check that there is enough memory on my computer. The message is also suggest to check that I'm authourized to use the target for extraction.

    I reinstalled LR5, I tried to download a new upgradefolder several times, I tried to extract it in different folders.

    There is enough memory and my computer meets the requirements. (I am the administrator of course.)

    Does anyone have a solution?

    Thanks in advance!

    After the recent update (security 2015-006, Mac OS 10.10.5, Yosemite), I can longer open all files in Microsoft Excel or Word.

    When I tried to open the files in the "Open recent" list, Excel reports "Excel cannot open the workbook. The file name or path contains invalid characters (for example, /). "Same error message appears when I go into the folder and open the file in Excel.

    When I tried to open an existing file of the word, he pointed out that "this is not a valid file name.

  • How to open my file after ' cannot find - filename-"error message?

    OK, the bottom line is, InDesign crashes and I can't recover my file. I get a "File not found" error message when I try to open the file.

    I use CS6 on a MacBookAir, OS X Yosemite.

    I tried to find the "InDesignFileRecovery" folder, I can not find anywhere, is not in my file library or Caches.

    However, I work in dropbox, so I headed over to dropbox to recover from their "previous versions". It starts to get weird. There are a lot of versions (I back up very regularly), but when I download a previous version (I know was fine) it downloads with the extension indd.txt. So I remove the txt extension and keep the indd and everything seems fine, but then that recovered file gives the same message. I tried renaming the file opening and recovered that same "file not found" error message.

    I can open InDesign and open the file from the previous day, but nothing of the box of older versions of work this day of. I'm SO sick of what's going on. It happened to me last week, so far I lost 20 hours work :-(

    I tried quit InDesign and restart the Mac, does not help. The only thing I can think of is to "save under" every two hours, at least, if all goes well then I lose only 2 hours of work.

    I found the answer on another thread. The solution is to open in InDesign and when you select the file to open, choose "open copy". It worked! Cannot believe it. Still don't know why dropbox tactics did not work well...

  • Cannot open .zip files after AutoUpdate
