Good Day I am a Ph.D. Student at Univ. Cumberlands. I tried to download the software as required by our course. Site source for download is gretl.sourceforge.net/osx.html Either option that is downloaded, does not open. The message given on my Mac is : the software needs to be updated for malicious software, contact developer. Greatly appreciate your assistance on this matter. Please confirm this email has reached you via reply. Respectfully, Satra
