I just reposted IDL 8.5 on my MAC Pro workstation running OS X El Capitan and I have received my new license.dat file but am unable to get the license activated. When I double click on the LicenseWizard an xQuartz windows opens but closely immediately and when i try to use the command line prompts i get the following errors. bash-3.2$ cd /Applications/exelis/idl85/bin bash-3.2$ . ./idl_setup.bash bash-3.2$ sudo ./lmgrd_install Password: bash-3.2$ sudo ./exelislicense IDL Version 8.5, Mac OS X (darwin x86_64 m64).
