You can customize the installation if you do not want to install all plug-ins.

Before the close of 2021 I was able to use the fabfilter plugins and I purchased during the winter sale. Now I’m hearing you have to have Mac OS 10.12 or higher in order to use them. Is there legacy compatibility for Q3, L2, MB and C2 plugins.
