iDefrag is advanced Mac OS X disk defragmentation and optimization tool. Supports the very latest features of HFS+, including journaling, case sensitive filenames and adaptive hot file clustering (which means it won't mess-up the Hot Zone).
What's new in this version:
- Minor change to the behaviour of the "Check for Errors" option.
- Compatible with upcoming Gatekeeper changes in 10.9.5 update.
- Fixed a hard-to-trigger bug in our HFS code that might have caused a crash.
