Delete file from Mac but not iCloud
I would like to use the iCloud in order to effectively manage my stuff so that I don't need to get a bigger hard drive for my MacBook. My plan was to put everything into the iCloud folder within Finder, and then select an option to remove the local copy and just leave a copy in iCloud Drive, available for me to download if I wanted it. This is what I did with my music collection when I got iTunes Match and it worked really well.
However I can't seem to find any way of making this happen? When they're syncing there is the little cloud symbol indicating it's syncing but when it has finished the cloud symbol completely disappears and I can't find an option to delete the file from the local drive without deleting it from iCloud Drive as well.
Any ideas? Am I just being daft and missing something obvious?! I've tried searching for help on it but couldn't see anything.
MacBook Pro, iOS 9.0.2
