Problems starting Lightning Controller II on Mac OS (Intel Mac, 2019)

Post by kalvemusic »

Hi together,

I just wanted to try the latest Lightning Controller Version II on my Mac. After downloading the Software I tried to start and got the following error message: efk_usb library not found!

I tried to copy the Image to my Programs folder (thought that the access to the file which exists within the folder would work than) but now chance.

Can you please tell me the issue with that?
(Mac OS Sequoia 15.7.2)

Best regards

honestly I did... to be sure I repeated all steps, but I still get the same error.
(I have a Mac with an Intel processor from 2019)
Not sure what I should try out next
