How do I use BuildPipeline to build for M1 Mac?

I'm trying to use the build pipeline to automate builds for different platforms, but there don't seem to be options for platform architecture. When using

BuildPipeline.BuildPlayer

I can only specify the target as

BuildTarget.StandaloneOSX

.

How do I specify platform architecture?

 

As far as I understand, the M1 Macs run MacOSX. Is this not the case?

 

Not exactly. If you look in Build Settings, you can select Intel 64-bit, Apple Silicon, or both.

I'd like to know how to set this in code with BuildPipeline

 

I found these posts:

  (^ this post is likely what you're looking for)

@Tautvydas-Zilys could probably be of better help for this.

 

Thanks Mauri, that second link was what I needed

 

If I understand this right this line will set the settings in the editor Build Settings only

Code (CSharp):

1. UnityEditor.OSXStandalone.UserBuildSettings.architecture = UnityEditor.OSXStandalone.MacOSArchitecture.x64ARM64;

In my case, I'm looking for a way to build for OSX intel 64 + apple silicon with

Code (CSharp):

1.   BuildPipeline.BuildPlayer(scenes, targetDir, BuildTarget.StandaloneOSX, buildOptions);

Is there any way to do this ?

 

This is me (one year later) wondering the exact same thing...

The lack of a BuildTarget for Standalonex64ARM64 makes it impossible to reliably build for anything else than Intel64 when calling BuildPipeline.BuildPlayer().

It could also be made possible by letting us specify a MacOSArchitecture in the BuildPlayerOptions.

 

Did you happen to get this figured out? I'm also trying to understand what we are supposed to be doing. Why is there no documentation on this? Very frustrating

Edit: I may have figured it out. Haven't tested this yet, but I think this is whats going on.

When you look at the tooltip for BuidlTarget.StandaloneOSX (which is now the ONLY non-deprecated OSX option), it says "Build a macOS standalone (Intel 64-bit)". I'm pretty sure this is wrong, and that behind the scenes its actually checking for this value to decide what to build:

Code (CSharp):

1. UnityEditor.OSXStandalone.UserBuildSettings.architecture

That can be set to either x64, ARM64, or x64ARM64. I'm assuming x64ARM64 is equivalent to the option you get in File -> BuildSettings to build for both architectures.

Used info from this thread:
https://forum.unity.com/threads/headless-builds-targeting-apple-silicon.1085177/#post-6993635

But I didn't know Apple Silicon uses ARM. I don't have a Mac and am not familiar with these sort of things. Kind of frustrating that its named "Intel" and "Apple Silicon" in File -> BuildSettings, but then x64 and ARM64 in the hidden setting that no one knows about, and that the BuildTarget has a wrong tooltip. Please fix, Unity!
