We are working with Apple to see if we can come to a resolution that will support reporting HW S/R and still work correctly with all versions of macOS. The 6.0.59 is reporting when the HW sample rate changes, and this is what is causing the problem on 10.12.6

MacOS 10.12.x has a bug that the v.6.0.59 firmware is stimulating the bug was not present in earlier versions of macOS and was fixed in macOS 10.13.x Jeremiah wrote on Sat, 28 July 2018 01:57 My ULN-2 and ULN-8 are not recognized as audio devices when connected using USB to my 2014 Macbook Pro is runs MacOS 10.12.6. I power cycled the box, and it didn't recognize it.Īfter connecting it to the Mac Mini and back, it recognized it again. (I reported this issue, it's obviously unrelated). I played some more music, added a channel strip to the main output. I disconnected from the Mac Mini, then plugged it into the Macbook Pro and it recognized it. I connected the box to the Mac Mini, it recognized it. I went through the four scenarios in my first paragraph, with no success. I managed to crash the box loading a macro, so I power cycled the box and it was no longer recognized. I was able to play music through both boxes.Ĭonfused, I plugged the ULN-8 into my MacBook and it recognized it as an audio device and played back music. I connected my ULN-8 to the same and it recognized it as an audio device. I connected my ULN-2 to an old MacMini running 10.6.8 and it recognized it as an audio device. I connected my ULN-2 to a Windows 7 box and it identified it as an audio device but stated that it couldn't start the device in Device Manager. MIO Console recognizes both units and let me update the firmware (the problem was happening before doing so too).

I have tried the above steps with MIO Console open and closed, without success. I have tried letting both units power on fully before plugging the USB cable in and power the units on while they are plugged in, but the units do not show up in the OS sound settings as audio devices.
