Hi
I've just started using the 'Beta' of the OneDrive for Business OSX client (Yosemite, 10.10.2). It seems stable and has already synced over 8GB of files for me.
One issue: please can it ignore . (invisible) files, eg, .DS_Store? I use the *nix side of OSX a lot and so I have invisibles showing; the OneDrive client tries to sync them, gives up, and I get 0-length 'new' files in the web interface as a result.
Ta for releasing it; we've just been told we're all moving to OneDrive (from DropBox) so I was panicking!
