Dear Casey,
The SDKtool interacts which whatever version of the ssc library you load. You can use the "Load/unload library" and "Choose SSC library" buttons in the Module Browser to choose a different library.
To load the current library in SDKtook for macOS, open a Finder window, and control-click the SAM app icon to show the package contents, and copy /Contents/Frameworks/ssc.dylib to the Desktop or some other folder you have access to. Then start SDKtool, and in the Module Browser, click
Choose SSC library and open the ssc.dylib file.
As you may already know, as of SAM 2018.11.11, the SDKtool now comes with the SAM desktop software. We did that with the intention of making it easier to keep code you generate from SAM consistent with the SSC library you explore in SDKtool. If you have more than one version of SAM installed on your computer, or copies of different SSC libraries, you can load those libraries in SDKtool -- for example, using SDKtool that comes with SAM 2018.11.11, you can load the SSC library from a SAM 2017.9.5 installation, or a copy of an even older SSC library version 174. The new instructions on the SDK page provides some additional explanation:
sam.nrel.gov/sdk.
Best regards,
Paul.
