Well people, it works.
I did exactly what the instructions in the link Purusha provided above and I now have Overbridge working with my Analog Four (1.23c) on macOS Sierra (with the new update pushed out today).
Now, admittedly, I installed the update but did not test overbridge with it without having first tweaked with the above instructions so two possibilities:
- The 10.12.1 macOS update fixes Overbridge (could someone test if that alone does the trick?)
- The technique that I'll describe below fixes Overbridge on macOS Sierra.
Here's the steps I took (modified it a bit from the instructions given on the virus board):
Open the Terminal app.
Copy, as a backup, your Overbridge kernel extension to the desktop:
sudo cp -a /Library/Extensions/ElektronOverbridge.kext/Contents/MacOS/ElektronOverbridge ~/Desktop/
Extract the 64-bit portion of the kernel extension and copy it back to your Extensions system folder:
sudo ditto --arch x86_64 ~/Desktop/ElektronOverbridge /Library/Extensions/ElektronOverbridge.kext/Contents/MacOS/ElektronOverbridge
No reboot necessary, I currently have Overbridge running inside Live 9.7 on macOS Sierra 10.12.1
Wow! Thanks a bunch @Purusha
