libpeerconnection.log on your Macintosh HD?

libpeerconnection.log – Google Product Forums. Turns out it is there because of Google Chrome. The issue was fixed in the past but appears again. Angelo-Victor Bratianu has the easy solution. Just go to your Utilites folder and then start terminal. Type this in:

chflags hidden /libpeerconnection.log

Then press Return/Enter. Then check and the file will be hidden!
