Okay.
That was the main thing I could think of that usually differs between ffmpeg and mp4box.
Enabling "Config->Output->Container Settings->Mp4 Settings->iTunes Compatibility" usually is also a wise choice when using Quicktime for playback.
Never really cared for Quicktime playback much, since they only support a small fraction of MPEG-4 ASP, MPEG-4 AVC and probably MPEG-4 HEVC.
Got no further idea without even knowing into what format you stuff into your mp4 files.

Ps.: haven't updated MP4Box for quite some time so my guess is that this is probably related to the encoder you use.
