I have a brand new 16 inch macbook pro fresh out of the box, installed the latest zsuite and the latest beta, and had no luck. The icon would appear for a second an disappear, running from “show package contents” gave me an error about not having permission to access the framework it needed.
I opened terminal and ran
“sudo /Applications/Z-Suite.app/Contents/MacOS/Z-Suite ; exit;”
that allowed it to open and stay open, and then open normally after that.
I assume there is a missing permission somewhere but I have a work around for now.
