Description

The documentation for QFileSystemWatcher says:

On Mac OS X 10.4 [...] an open file descriptor is required for
 each monitored file. [...] This means that addPath() and
 addPaths() will fail if your process tries to add more than 256
 files or directories to the file system monitor [...] Mac OS X
 10.5 and up use a different backend and do not suffer from this
 issue.

Unfortunately, the last sentence above is not true: see this commit ("Removing the usage of FSEvents-based backend for now as it has a few bugs...").

This means the current code for easyhg 1.2 fails badly on OS/X because it runs very quickly into kqueue's open file descriptor limitations.
