Hi there @Stefano_Ricci
Every ANA 2 presets packs from Sonic Academy comes with a Win & Mac installers.
On MacOS it's just a matter of running the .pkg installer and all file & presets are automatically installed in their respective directories on your Mac. The default install path on MacOS is /Library/Application Support/Sonic Academy/ANA 2/Presets ( this is the main MacOS Library folder, not the User Library ).
You actually don't need to access the presets, once you've run the installer(s) just open ANA 2 inside your DAW and you should see the new presets in the presets banks list, from the Pull Down Arrow next to Preset Name area. ( Pic 01 ).
Clicking on the Preset Name area will bring up the Presets Browser window and there's also a "Refresh" button at the bottom of the Presets Browser ( Pic 02 ).
So after a successful installation, all your new presets should appear in there.
