VerbSuite Classics by default comes with 7 different Reverb units. All of which are pictured below: 

Expansions can be downloaded individually within the Slate Digital Connect app. Please find installers for the app here: https://app.slatedigital.com/installers 

At this time expansions must be installed to the default location, and only then can they be moved to an external hard drive.

Once an expansion is installed, navigate to Macintosh HD/Library/Audio/Impulse Responses/Slate Digital/VerbSuite Classics/ and move the expansion to the desired location on external HD. Please refer to GIF below for clarification. 

NOTE: Default location is listed on bottom "Finder" window, and external HD is shown on the top window. 

Repeat this process for all installed VerbSuite expansions. Once all units have been installed, you should see units 1-12 listed in the "Devices" section. 

Expansion paths can be added by clicking on the "cog wheel" on the top left of the plugin window. Please see image below: 

NOTE: The paths listed in the image above are simply used as an example. Make sure to select each  expansion's directory up to the expansion name. For example: "/VerbSuite Classics/Bricasti M7 FIR8-96k". If this folder hierarchy isn't followed, the expansions cannot be loaded. 

Troubleshooting

VerbSuite Expansions will not load properly if the "Units" aren't found in the correct directory. Please navigate to the following path to confirm which VerbSuite Classics reverb "Units" you have installed on your machine:

Macintosh HD/Library/Application Support/Slate Digital/VerbSuite Classics/Units/

The image below is what factory default should look like. Units 1-7.

The image below is what all installed expansions should look like. Units 1-12. 

If there are missing units from this directory, please reinstall the expansions.
