Hello all, I have been struggling to open Figtree on my new mac. I finally succeeded today, so I thought I'd share.
I am working with the .dmg download (version 1.3.4) of figtree. (I've found the .tgz to be kind of buggy -- I could open it, but it had GUI problems.)
I was not able to open the application by pointing and clicking. From the iterm command line, these two commands worked for me:
export JAVA_HOME=$(/usr/libexec/java_home -v 1.8)
CLASSPATH=/put the path here/Figtree_v1.4.3/lib open -a /put the path here/FigTree\ v1.4.3.app/
As I understand it, the first command says which version of java to use. This should not be needed if you only have the one correct version of java installed.
The second command points figtree to the right libraries and then opens figtree.
