in the moment it is not possible to use the MR816 interface with osx el captain.
do anyone know a workaround. will steinberg satisfy customers with a firmware update for el captain and the MR816 interface?
thx and all the best.
I’m sure an update is coming. You might also want to keep an eye at this:
Yamaha was a bit faster than Steinberg to post a Yosemite compatible driver, perhaps they will this time as well.
