I found an old MIDI interface in my closet and hooked up the MCU through that, and – success! now i need to hook up the XT, but the old MIDI interface only has a single input, so unless i get another MIDI interface, i'll be using only the MCU for now. (apparently ports 3 and 4 are defunct when running it this way? thats what the manual implies.) its a step in the right direction. thanks for your help! i very much appreciate it.

ah...sorry. no luck means....the MCU Pro and XT proudly display their credentials, but none of the faders work. the only thing that does work is the transport. i can stop, start, and even activate record, but the channel strip faders are dead and the display shows nothing. since the last post, i tried more, and ended up getting (oddly) the XT to display channel names and the faders to work... only on the XT. the MCU itself is not responding. its very selective. then i will open up another project and none of it works. try another, and sometimes the XT works. sometimes. unfortunately i can't connect via MIDI only. my only choice is the USB. the MCU goes directly into the Mac, not via hub. my I/O is a Mackie Onyx Blackbird, Firewire, and there is no midi option on that either (that machine is its own unique headache, mainly due to lack of driver support from Mackie). so, to recap: yes, the MCU and XT are 'seen' but only function sporadically and in limited ways.

Hi - I'm sorry, i was not focussed on this issue for a while, but I'm back in the weeds again with it. I have tried this scenario about 8 times, with no luck. I have not missed a step: "1. Update your MCU Pro & XT Pro control surfaces to 4.0.3 (still no update for the C4 Pro) 2. Delete the control surfaces on LXP within the control surface setup 3. Quit LXP 4. Delete that .cs file in the hidden preference folder. 5. Turn off MCU & XT. 6. Restart Mac. 7. UNPLUG all midi cables & usb from MCU & XT (including those plugged into each other). 8. Launch LXP & open Control Surface set up. 9. While holding select buttons of faders 1 & 2 on each unit, turn on MCU & XT then select Logic by pressing vpots on either channels 7 & 8. 10. Plug MCU's USB into Mac (or your USB hub) then scan for new device. 11. Once the MCU is read/confirmed, plug the midi for the XT into & out of the MCU then scan for that device." beyond that, i have run out of ideas. (in the midst of all this, Apple released another little update for Logic, but it did not fix this issue). is anyone else out there still in the weeds on this one? setup: iMac 27-inch, late 2009 2.8 Ghz Intel Core i7 20GB RAM 2TB HD OS X Yosemite 10.10.2 Logic Pro X 10.1.1 Interface: Mackie Onyx Blackbird Controllers: MCU Pro + XT, v. 4.0.3 thanks

this shouldn't be listed as SOLVED, because it is not solved. I've tried every fix out there, and none of them work. unless I'm totally alone!

The solution posted by eightyocho does not work for me. I've tried it many times now.

this may be more of a Mackie issue than Apple. Mackie is not only notorious about being several OS's behind in their updates, but they also acknowledge it and yet offer no timeline at all. Their customer service is horrible. They cannot keep up with Apple.

such a headache. many Mackie users are very miserable right now. i've been following it. my workaround was this: i created a 100GB partition on my 2 TB HD. i downloaded a Mavericks installer, which i did by going to the app store and listing "purchased" items and there it was. trouble is, Yosemite will not run a Mavericks installer! (why?) SO - i dig out my Lion installer discs, boot from that, install Lion on the partition. Lion will NOT run the Mavericks installer unless its upgraded to 10.6.8, so i do that. THEN - Mavericks can be installed. so currently i run everything from the partition, until they release a fix. its a bit psychotic as i have to boot back into Yosemite to access certain files or run other things, but it is nice having a dedicated audio partition. I made my project files on the Yosemite partition available to the Mavericks partition, so i can go back and forth, although i worry i am creating a monster but i haven't run into any problems yet. I'm even running Logic X off the Yosemite partition, while in Mavericks. no issues. kind of weird. i would rather not do it this way, needless to say. Thanks, Mackie. I also have a Late '09 iMac and Blackbird, and found Mackie lagging behind on driver support back when I was running OS X 10.7...but the 4.0 drivers solved everything and it was running beautifully...and I have no excuse (other than stupidity) for rushing into Yosemite. What was I thinking??? When I contacted Mackie Support, this is the response I got: "The Onyx Blackbird is not supported OSX Yosemite and the v4.1.0 driver will not work. Here in Tech Support I do not have an ETA on when new drivers will be available. Keep connected to our website for any future driver updates for the Onyx Blackbird. My best suggestion would be to revert your computer to an older version of OSX." It's not a Firewire cable issue, it's their drivers (again)...so I guess I'm now looking for a new Firewire interface, because I don't want to go back to 10.9. (sigh) Probably go with Saffire, but if Santa comes early, maybe a Fireface. I think I'm done with Mackie. Love the hardware, but the driver support is consistently late.

I spoke with a Mackie rep, and you're starting to see this popping up on their Facebook page, too: they acknowledge the issue but have no ETA for a fix. I find this pretty crappy; the Yosemite public beta was out for months. they had no one working on this? I'm stuck facing the idea of downgrading to Mavericks, which I'm dreading.

I use a Firewire-based interface with my 27" iMac (2010) - the Mackie Onyx Blackbird. I researched online to see if there were any known issues and i found none, so i (probably hastily) took the plunge. Bad idea. Now the iMac 'sees' the Onyx, but the Onyx will not work -- it does not 'see' the iMac back. Its only been a day or so, and i opened a ticket with Mackie about it, so i hope there is a fix soon. Bottom line: Mackie Onyx Blackbird does not play well at the moment with Yosemite.
