Here are some news ...
As a workaround to this issue, you must activate RTAS for Oberheim SEM V so Analog Lab find the full plug-in.
Sorry for the weirdness and inconvenience.
The Oberheim SEM V installer copies the vst plug-in into /Library/Arturia/Oberheim SEM V only if the RTAS is installed (The RTAS wraps this .vst plug-in).
At the same time, Analog Lab searches for Oberheim SEM V.vst in the same directory.
This will be fixed in the next update Analog Lab by searching for Oberheim SEM V in /Library/Audio/Plug-Ins/VST.
Until it is released, the workaround consists in installing the RTAS plug-in.
The situation is exactly the same for Wurlitzer V, but Jupiter-8V is different.
Hope it helps,
