VST doesn't show up in Ableton

[Flowrest]

I tried to test the vst (Mac) in Ableton.
VST copied into the folder, Ableton started, click "Open anyway" in the security area, Ableton starts without problems, but the plug-in cannot be found in Ableton.
What could be the problem?

Glad to hear it works now. I assume you are the guy who contacted me today, right?
