Make for target dmg fails after Mac OS update to 12.3.1

Pre-flight checklist

• I have read the contribution documentation for this project.
• I agree to follow the code of conduct that this project uses.
• I have searched the issue tracker for a bug that matches the one I want to file, without success.

Electron Forge version

6.0.0-beta.61

Electron version

15.3.0

Operating system

macOS 12.3.1 Arm 64

Last known working Electron Forge version

6.0.0-beta.61

Expected behavior

I recently applied the OS update recommended by MacOS. The current version of the OS is 12.3.1.

Before the update, the build was working fine as expected.

Actual behavior

After the update, the build fails with the following message:

✔ Resolving Forge Config
We need to package your application before we can make it
✔ Preparing to Package Application for arch: arm64
✔ Preparing native dependencies: 2 / 2
✔ Packaging Application
Making for the following targets: dmg, zip
✖ Making for target: dmg - On platform: darwin - For arch: arm64

An unhandled error has occurred inside Forge:
An error occured while making for target: dmg
Command failed: bless --folder /Volumes/Trici --openfolder /Volumes/Trici
bless: The 'openfolder' is not supported on Apple Silicon devices.

Steps to reproduce

Update the macOS to the latest version and that should cause it to break.

Other libraries have reported same issue: https://github.com/tauri-apps/tauri/issues/3719 https://github.com/create-dmg/create-dmg/issues/127

I updated the electron-installer-dmg to the version 4.0.0.

After updating when I tried to make or publish I was getting the following error:

The code signing was failing. This was due the fact that a testapp binary was available in the location shown above. For older versions of appdmg that was not the case. For now I deleted the testapp binary from that location and the signature error does not happen anymore.

Not sure why the testapp binary is there for the latest version. The commits in the appdmg repo dont give any indication that this changed.

@singhshashi thanks for your answer, that’s not true unfortunately. It is trying to access APP-darwin-x64 file while making APP-darwin-arm64

UPD: never mind, that was my config problem (the name was hardcoded). I’m sorry for that and thanks for your help
