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.
