Could you build this?
Partial Duplicating macOS app bundles while altering their bundle identifier, sandboxed container paths, and application signatures to prevent collision requires specialized macOS system architecture knowledge.
What it would actually take: Built in Swift/Objective-C, it involves duplicating the `.app` bundle, modifying the `Info.plist` (specifically `CFBundleIdentifier`), re-signing the app with ad-hoc certificates using `codesign`, and provisioning separate container directories in `~/Library/Containers` or `~/Library/Application Support`. The hard part is bypassing modern macOS Gatekeeper, hardened runtime restrictions, and Apple Silicon code-signing requirements without invalidating proprietary apps or breaking iCloud/Keychain entitlements.
