FYI for any on Catalina follow these instructions to get it working!

1. Run this terminal command on the file: xattr -d com.apple.quarantine [path/to/extern.mxo] (see for details: https://cycling74.com/articles/using-unsigned-max-externals-on-mac-os-10-15-catalina)

2. Make a modification to the max patch by opening up the patch editor and typing into a text box and deleting it or anything else that doesn't modify the workings of the patch.

3. Save it. It should now work.
