Is there any free GAMESS input file maker for Mac OS?

My main purpose is to simulate excited state calculations on a molecule with Time Dependent DFT.


I am looking for free software that makes input files for GAMESS. I have tried Avogadro and it works fine (in Extensions> GAMESS > Input Generator > Advanced tab) but it can not make **TD-DFT** input codes.


I also checked the recommended software by the Gordon Group ([here](http://www.msg.ameslab.gov/graphics/other.html)) and tried installing some of them but couldn't install Gabedit at all (I was unable to compile the binary, maybe because I am using Mac OS X Yosemite). I also tried WebMO but it is available just on iTunes for iOS.


What I need is a software that makes the input code interactively to avoid possible errors.




If you can give me the requisite keywords for TD-DFT in GAMESS, it's not hard to add that to [Avogadro](http://avogadro.cc/)


I've never done TDDFT in GAMESS because I use other programs, but given a link to the docs, it's easy enough to enable more drop-down menus.


That said, you can interactively edit the text in the Avogadro input for *any* quantum program (not just GAMESS).

If you don't want to use Avogadro, the "native" program for GAMESS is [MacMolPlt](http://www.scl.ameslab.gov/MacMolPlt/) which was developed in the Gordon group itself. I haven't checked, but I'd assume it supports TDDFT options, since it enables pretty much everything else in GAMESS.

If you want to use Gabedit, it's in [Homebrew](http://brew.sh). Just `brew install gabedit` after you install Homebrew. I just installed it without issue on Yosemite and it was pretty fast. It seems to have a lot of options for GAMESS, but it's been a long time since I've done computational chem, so I can't tell you whether it has all the TD-DFT options. I didn't get any weird errors or anything, so it seems to run fine.
