2. OS X Mountain Lion (10.8.3+) Compatibility: If you are running an old Mac Pro or MacBook Pro from 2009-2012 on Mountain Lion, 9.1.8 is the only version that runs flawlessly without graphical glitches.
3. Improved Audio Unit (AU) Validation: This update fixed the infamous "AU Validation crashes" that plagued third-party plugins from Waves and Universal Audio.
4. Quick Swipe Comping Reliability: The take folder comping feature finally stopped losing edited fades when reopening projects.
5. Export All Tracks as Audio Files: A crucial feature for stem mastering was optimized to handle over 100 tracks without crashing.

Bottom line: If you’re running Logic Pro 9 on macOS Mavericks or Yosemite, 9.1.8 is the most stable version you can install. Logic Pro 9
