I don’t know if anyone has had/is having trouble installing the latest Dorico update because of trouble with the elicenser.
I never got the [Allow] message - the message I got was that Synopsos was already running something else (i.e. Sibelius which I had already quit and done a restart).
This Steinberg help article cured it for me …
If you simply click on [OK] in the error message box, your Steinberg program will get permanent access to Synsopos.app and its license can be verified successfully. In this case, no further action is required.
However, if you already have clicked [Don’t Allow], licenses cannot be verified and your Steinberg software won’t run. In this case, please follow these steps:
Select System Preferences… from the Apple menu.
Open the Security & Privacy panel.
Select the Privacy tab.
Select Automation in the list of options on the left as shown on the screenshot below.
The Steinberg program that needs to access Synsopos.app should now be listed on the right.
Check Synsopos.app beneath your Steinberg program’s entry.
If further Steinberg programs are listed, you might want to give them access to Synsopos.app, too.
Next time you start your Steinberg program, it will launch as usual.
