Just add "2>/dev/null" at the end of your command pipe as for example:
find . -name log 2>/dev/nullIn the instance anyone else comes across this problem,
the issue for me ended up being that the folder was "locked".
To remedy this, right click / ctrl+click your user folder and select Get Info.
Under the General subheading, deselect "Locked".
