Does your MAC unzip .zip files automatically?

When you download a .zip file in Safari on your MAC, does it unzip automatically?  This can be problematic if you are downloading .zip files for later use (such as future import into Blackboard).  There is a setting that you can change to prevent Safari from automatically unzipping the file:

  1. Open Safari.
  2. From the Safari menu, select PreferencesSafari preferences
  3. On the General tab, find the “Open Safe Files After Downloading” feature (usually at the bottom).
  4. Uncheck the box to prevent .zip files from opening automatically.   Disabling this feature can also help to protect your computer from malware and trojans.
  5. Once you have disabled the feature, download the .zip file again and it will remain intact without opening.uncheck

 


If you prefer to leave this feature enabled,  you can find the original .zip file in the trash.  Simply drag the original .zip file from the Trash to your desktop for use.

PDF files are blank and can’t be downloaded on a Mac in Firefox

Description:

Users have been experiencing difficulties with viewing/downloading/accessing PDFs in Firefox on a Mac computer.  A user clicks a link to a pdf and either nothing happens, or a new blank tab/window opens.  The PDF is never downloaded or opened.

 

Product affected:

Firefox on a MAC

Vendor response:

 
 

Problem resolved:

When you install or update Adobe Reader, it installs a plugin for viewing PDF files inside Firefox and sets that as the default. The problem is that this plugin does not work.   A workaround is available.  In order to view PDF files again follow these steps:

  1. In Firefox, go to the Tools menu.
  2. Select Add-ons.firefox tools addons plugins
  3.  On the left menu, click PLUGINS.
  4. Locate the Adobe Acrobat NPAPI Plug-in and click the DISABLE button on the right.  This will disable the Plugin.plugins npapi ask to activate
  5. Check the link to the PDF and see if you can now access the file.  If it is not working as expected, you will need to change the setting in Firefox.  From the Firefox menu, click Preferences.preferences
  6. On the Applications tab, do a search for PDF.
  7. Check the actions for the content type (application/pdf).  Change the action to match your desired outcome.  If you would like to Use Preview, select that option.  If you want to use Adobe Reader, select that option.  If you want to use a PDF Plugin that you’ve installed, select that option.   If there are no options available, select USE OTHER and locate the application on your computer that you would like to use to view the PDF.Applications pdf actions
  8. These actions should correct the problem. Check the link to the PDF again, and it should work as expected.   If not, please contact us.
