What is MacDupl?
MacDupl allows users to create isolated, duplicate instances of their existing macOS desktop applications. This means you can run multiple accounts for the same app simultaneously, each with its own separate logins, data, caches, and preferences, without any cross-contamination. It's designed for individuals who need to manage distinct work and personal accounts, or multiple client accounts, within the same application on a single Mac, eliminating the need for constant logging in and out.
The tool achieves this by cloning apps using APFS copy-on-write technology, making the duplicates lightweight and efficient. Each cloned instance appears as a genuine macOS app with its own unique identity in the Dock, Launchpad, and app switcher, identifiable by customizable color tints and badges. MacDupl automatically detects the app's engine (Electron, Chromium, Firefox, Native) and applies the appropriate isolation strategy, ensuring complete separation and privacy for each instance.
Key Features
- App cloning for isolated instances
- Separate logins, cookies, caches, and preferences per instance
- Unique color-tinted and badged Dock icons for each clone
- Automatic detection and isolation strategy for different app engines (Electron, Chromium, Firefox, Native)
- APFS copy-on-write for efficient disk usage (near 0 MB extra disk per clone)
- Centralized dashboard for managing all app instances
- Automatic updates for clones when the original app updates
- No telemetry or cloud-based data storage

MacDupl FAQ
How does MacDupl ensure data isolation between cloned app instances?
MacDupl ensures complete isolation by giving each clone its own separate logins, cookies, caches, and preferences. Credentials never leak between clones or into the shared Keychain. For Electron, Chromium, and Firefox-based apps, it provides full isolation, while native apps get an isolated home directory.
What happens to my cloned app instances when the original application receives an update?
When the original app updates, MacDupl automatically regenerates the clone from the updated original, preserving your existing login and data. This process occurs when MacDupl starts or when you launch an instance through MacDupl. To ensure clones are always up-to-date even when launched directly from the Dock or Spotlight, you can enable the 'Keep MacDupl running in the background' setting.
Why do cloned apps sometimes ask for macOS permissions (like microphone or screen recording) again?
Each cloned instance is treated as a genuinely separate application by macOS. This means that for security and isolation purposes, the system will prompt you to grant permissions (such as access to the microphone or screen recording) for each individual clone, just as it would for any new application.
Can I clone any application installed on my Mac, including those from the App Store?
MacDupl can clone most desktop applications installed on your Mac. However, sandboxed App Store apps, such as WhatsApp or Microsoft Office, cannot be cloned effectively. This is because their data often resides in a shared container that a duplicate copy would still access, negating the isolation purpose. MacDupl will hide these incompatible apps from its cloning options.
How does MacDupl manage disk space when creating multiple app clones?
MacDupl utilizes APFS copy-on-write technology, which means that clones share disk blocks with the original application. This makes the extra disk space required for each clone almost negligible, typically around 0 MB, even for large applications. Only changes specific to the clone consume new disk space.
