How do I sync iCloud iWork documents with Lion? I have been using my iPad with Numbers and would like to be able to just open them up on my Mac with Lion. I can not figure out how to connect/sync to iCloud documents. I have checked iCloud documents for syncing, but my documents don't appear on my Mac. 
I have even set up my mobile documents folder on the desktop. I can drag files to the iCloud that way, but then I can not open them from that folder. Frustrating.
Unfortunately, Macintosh does not (yet) support complete iCloud synchronization for documents. We can only hope that Apple will implement this at some point soon.

In the mean time, go to http://www.icloud.com/ and sign in. You can drag documents to and from the appropriate section on your computer, and it'll work with your iPad. There's still another bug, which involves Mac > Mac syncing, but as long as you just do iPad > Mac or Mac > iPad, it'll work fine. :)

Also, there is a folder located at ~/Library/Mobile Documents/ which contains your iCloud-enabled apps' data. This includes the iWork suite, but unfortunately iWork documents aren't saved as the normal filetypes (e.g. ".pages"), so they can't be opened on their own.
