I forgot, here's the command output:

Traceback (most recent call last):

in_file = open(in_file_name, "r")
IOError: [Errno 2] No such file or directory: '/Applications/Zenmap.app/Contents/Resources/etc/pango/pangorc.in'

I have encountered this issue on OSX 10.10.5.

Log output in /var/log/system.log:

Quick hack: Just create the missing file:

sudo mkdir -p /Applications/Zenmap.app/Contents/Resources/etc/pango && touch /Applications/Zenmap.app/Contents/Resources/etc/pango/pangorc.in

@functio Thanks for this workaround!

@functio ditto workaround!

@functio thank you very much！it work！

I believe this bug should be resolved with the 7.01 release. Please try the new .dmg installer at https://nmap.org/download.html#macosx and let us know if it solves this issue for you.

@dmiller-nmap 7.01 is good! i can use it in OSX 10.11.2

Yep; sorted thank you.

Thanks all! Keep scanning and reporting bugs.

I hate to re-has old issues, but this is happening on a fresh install of 10.11.3 with NMAP 7.0.1 installer. Anything i should be looking for? The workaround listed above also does not work.

FYI -- im getting a different command line error
./zenmap.bin: line 67: ./Contents/MacOS/python: No such file or directory

But the file is there...

Ditto on failing to closing after entering password.

Found solution

It looks like you have leftover files from the previous install of Zenmap. I don't know how to make an installer that deletes those old files, so for now you'll have to delete the Zenmap.app directory entirely and reinstall: sudo rm -rf /Applications/Zenmap.app/

@vinnytroia Please upgrade to Nmap 7.12, which should solve this issue. As @cybernorris points out, you may need to delete the Zenmap.app directory before proceeding. Also, you may encounter a crash in Zenmap that has a known simple workaround.

All you have to do to open Zenmap if this happens is to open terminal and put this in open -a Zenmap type in your password and it should open!
