My apologies if this belongs in another subforum. I have been having issues getting HALion to work on my Macbook Pro running 10.14, with no external drives attached.
Firstly - I downloaded the sounds installer via the Steinberg Download Assistant (which then proceeded to download the file via Chrome. Intentional?).
I then ran the dmg file, which seemed to run and install without issue. However, running the Steinberg Library Manager revealed that nothing was installed. I looked in both /Library/Application Support/Steinberg/ and ~/Library/Application Support/Steinberg/ for any HALion files but was not able to find any. I then copied all of the files from the Additional Content folder in the dmg to the VST Sound folders in /Library/Application Support/Steinberg. This caused the files to show up in the Library Manager.
However, when running Dorico, no HALion playback works. Loading and playing other VST instruments works without issue. Opening the edit panel for HALion in the Play window reveals the HALion GUI, but there are no instruments as options. I have attempted to attach a screenshot below. Hopefully it works.
I’ve done reinstalls with no more luck. Please let me know if there other steps I should take, or if anyone has gone through anything similar.
