macOS Mojave (10.14): private space not available in the Finder?

So, is there any way the fine folks at WD can expedite this update? It is completely unacceptable that developer betas for Mojave have been out since June and they didn’t see fit to plan ahead for this. This can be pretty crippling for users who rely on this service every day and now download files they need to work on, and save everything to their internal hard drives before transferring them to the cloud drive.

Come on WD! You’re a pretty large company to have not figured all of this out already
