Fixing MEGAN5 installer on Mac OS X Mavericks

I couldn’t install MEGAN5 on my Mac running OS X Mavericks, as it was complaning that the installer was damaged.

The solution was to remove the com.apple.quarantine attribute.

Mount the MEGAN5 installer .dmg file and then copy it to a writable partition such as your home directory:

cd ~
cp -Rf /Volumes/MEGAN .

Then remove the com.apple.quarantine attribute from the files:

sudo xattr -d -r com.apple.quarantine MEGAN

Then run the installer from your home directory as normal.
