What's new in this version:
- Fixed iDefrag to work on 10.10 again (was partially broken in 5.1.2 because of a bug in OS X and/or the developer tools relating to code signatures).
- Improve the rejection of old licenses to make it obvious what’s happening.
- Fixed an unusual crash that might be caused by pre-release versions of Mac OS X.
