Hi SandyCohen
Glad to hear your enthusiasm regarding the Mac beta so far!
The Web Standalone is unfortunately not a 1-on-1 and will show equivalent to our 'Draft' rendering mode, this is the same when not on Mac, this is simply due to technical limitations, you can find more information on the limitations in our Knowledgebase article here as well.
Video textures are also not supported due to these limitations, it seems we hadn't added that to the list yet, however.
Should there still be a big difference between your project and the Web Standalone then you can of course contact us to see what might be causing this.
Some example images of the 'Draft' quality project vs. the Web Standalone would be helpful in that case.
Regarding the disabling of WASD controls for Web Standalones, this is due to some key combinations that are often made as mentioned by Alexander in this post.
You can however forward your feedback directly via our Public Voting Portal here to our Product Management team.
