I currently have my macros sync'd to the "old" machine (Intel Mac Mini) where it works perfectly (pops up a window with the results of the command). Nothing happens on the new machine when I hit Run. I checked Accessibility permissions for both KM and KME. What am I missing?
At one point, I was trying to get a shell script working and found a post here (can't find it now) that had a script that would ensure the KM shell environment had the same path as the terminal. I downloaded and ran that script and for some reason, the ENV_PATH variable it created in settings was the actual command I was trying to get to work. Once I deleted that ENV_PATH variable, everything worked as it should. Thank you @griffman for the help! The script was called "Make ENV_PATH Variable in Keyboard Maestro using the Terminal v1.00"
