Can't reliably compile for Apple M1

[grex]

tldr: What is the correct way to enable M1-compatible builds?

We're using NatCorder in a Desktop Unity project with a NatML Cloud subscription (username grex).

In order to create a working build that will work on Apple M1 Silicon ...

• we have to change this file Packages/ai.natml.natcorder/Plugins/macOS/NatCorder.bundle (i can't seem to find the original forum and/or discord link for this fix)
• and change its Mac platform setting to AnyCPU (from x86_64). When compiled without this change, the build will throw a DllNotFoundException on launch.

However, the file constantly gets reverted to the x86_64 value and Unity spits out the following warning: The package cache was invalidated and rebuilt because the following immutable asset(s) were unexpectedly altered: Packages/ai.natml.natcorder/Plugins/macOS/NatCorder.bundle

• What is the correct way to enable M1-compatible builds?
• And if it means modifying this file, how do we prevent it from constantly being overwritten?

Our modified NatCorder.bundle: https://gist.github.com/grex/61e041103d242629a592a9bb0d11f3ce

Diff: https://www.diffchecker.com/3mEcRjQu

Our NatCorder version is 1.8.4 (also tried 1.8.6 but same problem persists)

Hey @grex what version of Unity are you using? It seems that Unity changed the plugin importer in Unity 2021, so I was able to confirm this issue. I'll publish an update later today with the fix.

The workaround is to manually import NatCorder into your project:

1. In manifest, import the ai.natml.hub: 1.0.9 package instead.
2. Download NatCorder as a .zip from GitHub.
3. Unzip and place the folder in your Packages/ folder.

Thanks for bringing this to my attention.

Thank you! Our Unity Version is 2021.3.0f1

Fixed in 1.8.7.
