Hi, Paul,
thank you for your response! I use macos 13.2 on a completely new Macbook M2. All the installation is new, there is no Time Machine Backup or anything similar involved. I un- and reinstalled "Vienna Assistant" and "Vienna Ensemble Pro" (previously removing many other related things from other folders like Cache, Application Support, Preferences...), but to no avail. VEP keeps installing the Helper Tool, whenever I open it.
One thing that caught my attention was that the plugin scan cannot be finished, because it "quits unexpectedly" due to Steinberg's "The Grant". Which is a bit strange, because eventually it is listed as a VST3 plugin. (See screenshots)
And since you ask: no, I do not have any special security settings, all system settings are the way how they were, when the computer was delivered 3 days ago.
On a side Note: in another post I reported that the logged-in status is not remebered on Chrome (and some other browsers). This is again true on my new computer with a clean and fresh install of the latest Chrome browser. The logg-in status is deleted as soon as I close my browser. When I open it again, I have to log in again...
