I am not sure why this is happening, but on my macbook macOS Sierra log files are being written to /private/tmp that look like this:

wifi-11-25-2019__21:01:29.log   wifi-11-25-2019__21:06:18.log
wifi-11-25-2019__21:01:30.log   wifi-11-25-2019__21:06:19.log

wifi-11-25-2019__21:01:36.log

The only reason I found this was because System was over 100GB and I investigated with Disk Inventory X and saw the log files wasting my SSD. I have a feeling it is the airport utility.

How can I stop this from happening?
