Hello everyone,

Every time I try to open gse_mapviewer via the terminal on Mac OSX, I keep getting the message: "This program needs access to the screen.
Please run with a Framework build of python, and only when you are
logged in on the main display of your Mac."

I do not know how to get past this issue on my computer.

Any help would be appreciated.

Sorry, this is a complete pain inflicted by Anaconda Python on Mac OSX. FWIW, it's a daily struggle for me too, and I've complained to them. ;)

There are two possible solutions:

   a) [recommended for most Mac Users] Install the Larch Apps. using one of these methods:
         1. Open a Terrminal, and type 'larch_makeicons'. If this does not work, make sure Anaconda was installed and
            that the Anaconda bin directory is in your path. Or maybe just type $HOME/anaconda2/bin/larch_makeicons

2. Or, browse in Finder to $HOME/anaconda2/bin (or where ever you installed Anaconda python) and click on `larch_makeicons`

This will create a Larch folder on your Desktop with several Apps (with icons and everything!) including Larch_GUI and GSEMapViewer.

b) [python-aficionados] Use 'pythonw' instead of 'python' to launch Python apps that will draw to the screen, as with

pythonw $HOME/anaconda2/bin/gse_mapviewer

You can even edit the gse_mapviewer to have 'pythonw' instead of 'python' in the first line. This won't persist through updates.

OTOH, if you install from source, this will get fixed at install time. I believe there might be a way to fix this at "conda install time",
but I haven't worked out the details for that yet.....

Hope that helps!
