Question: Electron/Electron Builder get info about binary

[jrohlandt]

We are distributing our Electron app for Macs using Intel and also Apple Silicon. We are using electron-builder --mac --x64 --arm64 to create an Intel and ARM version.

I need a way to know if a user on Apple Silicon has accidentally installed the Intel version of the app.
Currently I'm able to get the platform and architecture of the system.
But how can I get the architecture that the .dmg file was built for?
I thought "process.target_arch" would be it but it is always undefined.

Electron: ${process.versions["electron"]} Node: ${process.versions["node"]} Chromium: ${process.versions["chrome"]} Platform: ${os.platform} Architecture: ${os.arch} Target Arch: ${process?.target_arch} OS Version: ${process.getSystemVersion()}

I'm not sure it's possible to detect DMG architecture. I was under the impression that it wouldn't matter to the host system since the app within it could still be a different arch than what the OS of the DMG was built on/for.

FWIW, the electron-updater autoupdater should automatically update to the arm64 version of your app, even if the intel version was initially installed

electron-builder/packages/electron-updater/src/MacUpdater.ts

Lines 81 to 87 in afc6a34

	// allow arm64 macs to install universal or rosetta2(x64) - https://github.com/electron-userland/electron-builder/pull/5524
	const isArm64 = (file: ResolvedUpdateFileInfo) => file.url.pathname.includes("arm64") || file.info.url?.includes("arm64")
	if (isArm64Mac && files.some(isArm64)) {
	files = files.filter(file => isArm64Mac === isArm64(file))
	} else {
	files = files.filter(file => !isArm64(file))
	}

Ok thanks.
