Dear all,

I am trying to install the last version of JabRef 4 for OS X (JabRef\_macos\_4\_0\_0-beta.dmg) but the installation did not work. I run the following commands bellow to make sure that I have the correct java versions. My java version seems fine for me, but please let me know if you have any idea how I could fix this problem.

Many thanks, Fernando
