feat: build macos universal for binary and installer

[hiento09]

Description:

We need to enhance our build process to support macOS universal binaries and installers. This will ensure compatibility across both Intel (x86_64) and Apple Silicon (arm64) architectures.

Requirements:

• Build the macOS universal binary (combining x86_64 and arm64 architectures) for the application.
• Modify the installer to include the universal binary, ensuring it can run on both Intel and Apple Silicon machines.
• Update the CI pipeline to automatically build the macOS universal binary and installer as part of the release process.

Acceptance Criteria:

• The application should run natively on both Intel and Apple Silicon Macs.
• The installer should properly detect the architecture and install the universal binary.
• Verify that the build process is integrated into the CI pipeline and functions as expected.

Additional Notes:

• Test on both Intel and Apple Silicon Macs to ensure compatibility.

We need to modify the macOS updater source code and test it as well cc @vansangpfiev @dan-homebrew @gabrielle-ong

Include @vansangpfiev here for the macOS updater source code change.

@hiento09 FYI, for 154, I ran the Universal installer. However, when running a model, encountered the following error:

@hiento09 FYI, for 154, I ran the Universal installer. However, when running a model, encountered the following error:

@dan-homebrew can I check how you installed version 154 nightly? I just tried the following scenarios for Mac silicon and Mac intel and they all succeeded:

• Fresh install using the local installer universal
• Fresh install using the network installer universal
• Update from an older version before the Mac universal version existed

I just tried a scenario as follows and encountered a similar issue to what you mentioned:

• My machine is a Mac Silicon
• I downloaded version 152, but the mac amd64 version – it still installed because my machine has Rosetta, but at this point, the llamacpp engine installed is the amd64 variant, which causes it to not run on Mac Silicon.
• I ran cortex update to download version 154 universal and tried running cortex chat tinyllama:1b-gguf.

@hiento09 I'm closing this issue as the mac Universal installer is complete. Thank you! 🎉
