Cannot copy the required library into /usr/lib --- not permitted

[enzyme69]

I am following your tutorial but stuck here: 192-168-1-7:lib jimmygunawan$ sudo cp /Users/jimmygunawan/Downloads/librecord3d_unity_streaming.dylib .

Operation not permitted. And I cannot just drag and drop in Finder either.

@enzyme69 If you are unable to copy even with sudo, then is an alternative you can try; make a new folder in e.g. Documents — let's call it record3d_lib — into which you copy librecord3d_unity_streaming.dylib and then you just add record3d_lib into the DYLD_LIBRARY_PATH:

# Copy the .dylib into a folder
mkdir /Users/jimmygunawan/Downloads/record3d_lib
cd /Users/jimmygunawan/Downloads/record3d_lib
cp /Users/jimmygunawan/Downloads/librecord3d_unity_streaming.dylib ./

# Open .bash_profile to save the "library-lookup" folder
open /Users/jimmygunawan/.bash_profile

Add this line on the end of .bash_profile and save it:

export DYLD_LIBRARY_PATH="/Users/jimmygunawan/Downloads/record3d_lib:$DYLD_LIBRARY_PATH"

Now you should be able to run the demo — let me know if that helped.

I followed your direction on file copy and path inside .bash_profile but not 100% sure if all I did was correct because I am still seeing nothing in Unity.

I updated the README with new instructions (the old instructions were meant for Mac OS 10.13).

In short: instead of copying the .dylib into /usr/lib, it should be copied into /usr/local/lib as that is the same place where the library gets copied when building it from sources.
