Opening Mobile Documents folder in Finder on Sierra As of Sierra(?) opening ~/Library/Mobile Documents in the Finder actually takes you to ~/Library/Mobile Documents/com~apple~CloudDocs. This the Finder stylizes as "iCloud Drive" and only has folders for certain applications.

It is still possible to access Mobile Documents proper through Terminal, but even when opening the directory in Finder directly from Terminal it redirects to com~apple~CloudDocs.

Is it possible to access the root Mobile Documents folder from Finder?
I found a really nice type of workaround for this from here. Essentially you need to run the following command in Terminal:

ln -s ~/Library/Mobile\ Documents/ ~/Desktop/Real\ iCloud\ Drive


This will create an alias on your desktop that shows all the folders in the Mobile Documents folder when you open it. You are free to browse it to your liking—albeit with one caveat: you can't directly open any folders. You'll have to use the list view's ability to expand folders and then view files from there.
