Hi Eugene,

based on the log you provided I believe the issue seems to be with macfsevents, not doit itself.

If macfsevents 0.8.1 does not work have

• tried a different version (0.1, 0.2, 0.2.1, 0.2.2, 0.2.3, 0.2.4, 0.2.5, 0.2.6, 0.2.7, 0.2.8, 0.3, 0.4, 0.5, 0.6, 0.7)?
• checked the macfsevents Git repositories for related fixes?
• discussed the issue with macfsevents upstream?

Best, Sebastian
