@simonpham After check your solution, seems like it need Cmake rebuild that rlottie? Sorry I am a Unity Developer and have no experience how to do it, need more clues.

Hello @chile109, thanks for trying out. It seems that the current compiled native libraries are targeting only x86_64 architecture. And you have the arm64 CPU.

You can check it yourself In terminal:

konstantingindemit@Konstantins-MBP OSX % file libLottiePlugin.dylib
libLottiePlugin.dylib: Mach-O 64-bit dynamically linked shared library x86_64
konstantingindemit@Konstantins-MBP OSX % file librlottie.dylib
librlottie.dylib: Mach-O 64-bit dynamically linked shared library x86_64

Can you please try out the attached files. Archive.zip You need to unpack the zip archive, close Unity project and replace the dylib files in the git/unity-rlottie/unity/RLottieUnity/Assets/LottiePlugin/Plugins/OSX folder.

With the attached files I get following in terminal:

konstantingindemit@Konstantins-MBP rlottieOSXArm64 % file libLottiePlugin.dylib 
libLottiePlugin.dylib: Mach-O universal binary with 2 architectures: [x86_64:Mach-O 64-bit dynamically linked shared library x86_64
