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.
