I notice the system storage space slowly creeping up. I was about 11 GB a couple of weeks back, now showing 14.97 GB. How do I find out what is causing this? I *think* part of it may be downloaded software update (that is not installed yet), but I suspect that is only a small portion of the increase. Running Sierra 10.12.1 15 inch Pro (mid 2015) 2.2 GHz / 16 GB / 256 GB Iris Pro Thanks!
