Narrative:

I departed M78 and after landing I was informed that an unknown aircraft crossed close to my aircraft at M78. My company has tracking capabilities continuously showing my location; altitude; direction and speed. I did not see the other aircraft in that area or hear any radio transmissions from the aircraft on CTAF. I had switched to company frequency in about the mentioned area. I was told the other aircraft was on a simulated instrument approach with a safety pilot and was maneuvering for the approach to M78. It was a cavu day.
