Installed Cubase 9 on Mac and it's no where to be found

Hello, I recently got a Zoom R16 and was having some issues with it, though I might use a different DAW (my got to for the last 7 years has been reaper) and see if that was the issue - went to install the Cubase 9 demo, went through all the steps, and it’s not appearing anywhere on my Mac and I appear to be missing 8 odd gigs now. Any help would be much appreciated!
