Apple released OS X® Yosemite this week. MOTU has worked with Apple to ensure current MOTU products are compatible with OS X Yosemite, and to provide a smooth transition for your MOTU products when you upgrade to OS X Yosemite.
The latest versions of all MOTU software and audio/MIDI hardware drivers available at motu.com/download (including several driver updates posted this week) appear to be compatible with OS X Yosemite, although compatibility testing is still on-going. In some cases, MOTU software updates may be available soon to achieve 100% compatibility. Check motu.com frequently for further announcements in the near future.
