Issue: Downloading the MacOS version of IConyc and opening it brings up this error.
Fix: Run the command in MacOS Terminal:
xattr -cr <Location of the app>
and it will run.
Since I have an Intel Macbook I can send the file after running the command (and it may fix it), or you could include this fix in the description of the itch page. Hope this helps.
