Select and mask tool not working CC2017

[zxcvbn1234]

I tried using the new select and mask tool (having been very familiar with the old refine edge tool) after upgrading to CC2017 and when that launches, the tools do not work. The lasso tool does not create a selection, and if I bring in a selection started in the main photoshop workspace, the refine edge brush tool does nothing when I paint over the edge.  The transparency slider also does nothing.  I am working on a MAC running Sierra. So far this is the only bug I've found in the update.  Anyone else having this problem?

Guess I will call Adobe support because I have tried everything everyone suggested on here, and now my laptop  photoshop home screen is just blank. There are no tutorials there like there used to be now that I changed the preferences.
