Rharv is correct. The main program can go on your boot drive, what you called the 1TB HD. The RealTracks and RealDrums (which take up much more storage space) can go on the SSD internal drive. The installer can make this distinction; you do not need to move anything manually afterward. For specific instructions, Jim is correct that the Mac forum would be a better place to get that help. Most of us use the Windows version.

You didn't ask this, but you could decide to install all of BIAB on the 2 TB SSD drive. If your 1TB drive is a hard drive, BIAB will work best on the 2TB SSD.
