Strange... Seems like a leak in the Intel card graphics driver. MM is not allocating any graphic card resources while playing (just when starting a new media) and if there was a leak we would see it wathever the hardware / OS Version.
Do you activate "Use Hardware Acceleration" on your movie ? Is it playing with FFMPEG or AVFoundation player ? You could try switch this option on or off. It should have no effect, but that's an interesting test (in the case of AVFoundation, Apple framework handles the video textures itself, so if MM crashes with that, QuickTime player should also crash after playing back the movie for a week
If you are actually using AVFoundation, you should try with FFMPEG, but not with ProRes cause it's slow with FFMPEG. Use H264.
Here are your other options:
- Try with 10.12 (graphic drivers are different on different OS Version)
- Configure your computer to reboot for instance each 2 days at a specific time and put your MadMapper project file in startup items (and MM preference / Misc / "Fullscreen when opening a project at startup" checked)
