I had to uninstall Overbridge in Sierra, even with using the steps outlined here using ditto to strip away the 32 bit portion of the kernel extension.
On my machine it worked, but the system was using so much CPU that it was impossible to work, so I looked at Console.app and there were thousands of assertion errors from Elektron every second (something about buffer being 48 when it should be 0).
I’m guessing if it was as easy as to just strip the binary, they would’ve released an update already.
Just want to shout out a massive thanks to this forum.
Coming from El Capitan on a fully loaded Macbook Pro 2013 with Overhub only recognising 1 of my machines… USB 2.0 trick didnt work…
Upgraded to Sierra and followed the little Terminal hack after re-installing Overbridge and rebooting and now I get 6/6 in A4 and 8/8 on Rytm on the USB 3.0 cable supplied - Ableton working without a glitch (for now!)
In any case, massive thank you to all contributors for their insight - it’s forums and members like these that make this all worthwhile. so THANK YOU.
Yep - I was in the same boat. I was telling this to both Elektron and Access support and neither would believe me. Both kept telling me that they had the same Mac as me and there were no problems.
I’m convinced that Apple has been doing something like - using different USB chips, from different manufacturers - even on the same model Mac, where the MacOS driver support for one is/was worse than the other.
Still, after nearly 2 years struggling, looks like they eventually came through.
I wrote to Elektron support a cpl of days ago when the USB 2.0 trick didnt work… this is what they replied which is pretty much consistent with what we know. Unless I missed it in this thread, I was not aware of the “place at opposite ends of the overhub” trick mentioned in their reply:
This is unfortunately an issue in how OS X handles USB connections. The operative system doesn’t allow the user to allocate more than 2 channels in some cases. Our drivers and hardware (Overhub) cannot change how the operative system handles USB devices. What you could try however is to connect your Rytm and Analog four to the opposing sides of the Overhub (far left and far right port), this should use both individual controllers on the Overhub and should let OS X address them separately.
More specifically El Capitan. They introduced some changes to the USB stack in that update to harmonize with iOS. Caused a lot of issues unfortunately. Seems to be better in Sierra.
Thank you so much! Just got my new Rytm and I don’t have free inputs in my audio device, so without Overbridge things were looking bleak… But the kext fix terminal commands + reboot worked! \o/ (10.12.1, not clean install.)
