# OS X Mountain Lion

# ENVI 5.0 and OS X 10.8 installation

<span class="caps">ENVI</span> 5.0 requires additional packages not included in OS X 10.8 Mountain Lion.

Java – <span class="caps">ENVI</span> has required Java for years. The <span class="caps">ENVI</span> installer will prompt the user and download it as part of <span class="caps">ENVI</span> installation.

X11 – X11 is no longer included with Mountain Lion, but the installer will prompt the user to manually download X11 v2.7.2 or later from [http://xquartz.macosforge.org](http://xquartz.macosforge.org)

Installing X11 using the installer defaults seems to work for most users. v2.7.4 was tested and does seem to work.

# Install Sophos on Mac OS 10.8

By default, Mac OS 10.8 only allows users to install applications from ‘verified sources’. <span class="caps">BOL</span> downloads are not verified; therefore, upon installation you will receive the error message: “Downloaded Program.mpkg” can’t be opened because it is from an unidentified developer.

To allow the installation:

Go to System Preferences—&gt; Security &amp; Privacy  
Click on the lock icon in the bottom, left corner and enter the Admin password  
In the General Tab, under the header “Allow applications downloaded from:”, choose Anywhere.
