Hi everyone, sorry for replying to an old topic but I didn't see anything else close to what I am looking for, and would prefer to do this rather than create a new topic.   As you can see in the screen shot below, via the dashboard, I'm able to list the OS and even export it via CSV. This is great, but is only good per-network.  I can't list all devices on all networks at once.  However, when I try to query the same OS info via the API, it's hit or miss at best. It only ever shows "Windows", where the dashboard shows the various versions of Windows detected.     I'm using the networks endpoint refrenced above: https://api.meraki.com/api/v1/networks/<NETWORKID>/clients   Below is an example of a few of the fields retrieved when looping through the clients retrieved.  OS2 field is the field deviceTypePrediction.     Below are all the fields for one device, where it just shows "Windows", where the dashboard shows "Windows7/Vista".     Is there something I'm missing?   Thanks! ...
