[Build] Released asset for v1.20.1 doesn't work on macOS Sequoia

[avijit-chakroborty]

Describe the issue

There are two released artifacts for the v1.20.1:

1. onnxruntime-osx-arm64-1.20.1.tgz
2. onnxruntime-osx-universal2-1.20.1.tgz

The first one won't run onmacOS Sequoia with M3 with unloadable mach-o file type 10 error:

The XCode Toolchain I used has the following version:

$ pkgutil --pkg-info=com.apple.pkg.CLTools_Executables
package-id: com.apple.pkg.CLTools_Executables
version: 16.2.0.0.1.1733547573
volume: /
location: /
install-time: 1734109928

The Second one (onnxruntime-osx-universal2-1.20.1.tgz) has both x86 and arm64 as expected. But runtime is very slow. For SLM models such as llama3.2-1B ONNX we are getting around 120 tokens per second when built from source, whereas with this version it's about 1 token per second!. Perhaphs a Debug version is included in the released tarball?

Eitherway, it's impossible to use onnruntime 1.20.1 on macOS uness built from source.

Urgency

Many of the developers use MacBook for their development platform. Since the release is broken for Mac, it would be very nice to address this for the upcoming release v1.20.1.

Target platform

macOS M3 running Sequoia 15.3.1 with XCode toolchain 16.2.0.0.1.1733547573 or later

Build script

Compile any c++ progarm linking with the onnxruntime on macOS Sequoia and the weeor will show up during running.

Starting with the simpler onnxruntime-osx-arm64-1.20.1.tgz.

Looking at the library it appears to have been built for arm64 as expected. I'd suggest you check how you're loading/using the library.

tmp/onnxruntime-osx-arm64-1.20.1/lib/> file libonnxruntime.dylib
libonnxruntime.dylib: Mach-O 64-bit dynamically linked shared library arm64

Thanks @skottmckay for looking into this. After debugging of my build setup - it turned out to be an issue on my side. So closing this.
