I'm wondering if anyone has Yosemite yet and if it's causing compatibiility issues. I'm guessing Logic Pro X will work, but I'm curious about Logic Pro 9, the Native Instrument stuff, Reaper, etc. I konw it's early, but I'm curious. I was pleasantly surprised that Logic Pro 9 works with Mavericks - hoping I can squeeze one more OS update without having to buy the update for Logic.
