posting this before Chris posts a solution. I followed this thread with the same problem and managed to get it working. Essentially goes like this: 1. successfully execute ./install-cnet.sh with no apparent problems, the error occurs when calling the executable cnet 2. install anaconda for mac from [https://www.anaconda.com/download/], make sure its specifically for M1/M2/M3 by selecting drop down 3. once its fully installed, a compatible version of libc++.1.dylib should come with it, for me it was located in [/opt/anaconda3/lib/libc++.1.dylib] 4. create a symlink from that file into [/usr/local/lib], which I did with the command [sudo ln -s /opt/anaconda3/lib/libc++.1.dylib /usr/local/lib/libc++.1.dylib] 5. calling cnet will now come with another error that libunwind.1.dylib is required in @rp*th (which is shorthand for /usr/local/lib by default) 6. download the libunwind.1.dylib file given by Chris earlier in this thread and place it into the [/usr/local/lib] directory and cnet should now work
