Apple has released their new OS , I am happy to say, Vezér is fully compatible with 10.10 Yosemite. But don't rush, before upgrading to the new OS, here is a checklist to make sure everything will be working:
Make sure all of your apps compatible with Yosemite.
Make sure all of your gears (MIDI devices, capture cards, etc.) works well with Yosemite.
Do a backup of your system before upgrading to Yosemite.
