Version 4.1.8 fixes a few critical bugs, and the Mac installer is now signed with our Apple Developer ID so it will install without complaining on Mac OS X 10.8 and 10.9. We are still working on a few fixes for 10.9 Mavericks but those require a bit more time and will be released in version 4.1.9.
Hit that download, then read the short releases notes:

[FIXED] SMPTE delay causes weird jumps around the 1 (and 2 and 3 and…) minute mark
[FIXED] Arena doesn’t remember DMX Preferences
[FIXED] Clip menu does not always work for active clip
[FIXED] Crash on shutdown with windowed output
