Have been trying to fix this editor access problem for Embedded Python Block work for a long time on MacBookPro, Intel CPU, Sequoia, radioconda.
It had worked a while back then stopped. Have re-installed GNURadio several times trying gnuradio, MacPorts, HomeBrew and cleaned and reloaded Mac. Still have the python window come up that says Open in Editor or Choose Editor and both bring up the empty file window with no editor access. Something somewhere isn’t set right. Regards, Craig.
