Clone apps into isolated instances
MacDupl turns an installed Mac app into a separate instance with its own login state, data, and Dock identity. The original app stays intact and can still be launched independently.
MacDupl
MacDupl is a macOS utility that clones installed desktop apps into isolated instances so separate accounts can run side by side with their own logins and Dock icons. It supports a free trial, then continues free with one clone or unlocks unlimited clones with a one-time purchase.
What MacDupl does
MacDupl is a macOS utility for creating isolated copies of installed desktop apps so each account can run in its own app instance. The product is aimed at people who need separate work, personal, or client logins without repeatedly signing out.
Each clone is presented as a real macOS app with its own Dock icon and account state. MacDupl says it uses local APFS copy-on-write duplication, so clones launch quickly, share disk blocks with the original, and keep their own logins, cookies, caches, and preferences separate from one another.
The product is designed around common desktop app families that are difficult to multi-account cleanly, including Electron apps, Chromium browsers, Firefox-based apps, and some native apps in beta. A free trial unlocks the full feature set for seven days; after that, MacDupl can continue free with one clone or be unlocked with a one-time Pro purchase.
Core features
Engine-aware isolation
The app applies different isolation methods depending on the app family: full isolation for Electron apps and Chromium browsers, dedicated profiles for Firefox-based apps, and an isolated home directory for supported native apps in beta.
Fast, low-disk creation
Clones are assembled locally as APFS copy-on-write duplicates, so creation is fast and the clone shares disk blocks with the original. The site says a second instance is typically created in about two seconds.
Separate visual identity for each account
Each clone gets its own color-tinted, badged icon and a distinct identity in the Dock, Launchpad, and app switcher, with nine icon tints to help distinguish accounts.
Instance management in one place
From one dashboard, you can launch, stop, reset a session, recolor, or delete an instance. MacDupl also handles signed automatic updates.
Automatic app discovery and compatibility lookup
MacDupl scans the Applications folder and classifies what it can clone automatically. The compatibility page also lists supported apps and lets users request one if needed.
Common ways people use MacDupl
Separate work and personal accounts
Keep a work login and a personal login open at the same time in separate app instances, so account state does not bleed between contexts and you do not have to sign out repeatedly.
Client or workspace isolation
Run different client, tenant, or workspace accounts side by side for apps such as Slack, Notion, Figma, and similar desktop tools, with each clone maintaining its own data and preferences.
Dedicated browser profiles
Create isolated browser instances for Chrome, Brave, Edge, or Firefox-based workflows when you need separate profiles, sync accounts, or extensions without mixing them together.
Multi-account native app workflows
Use beta-supported native apps to keep account sets or settings apart when a direct-download version is available and the app is not sandboxed.

- Uses local copy-on-write duplication, so clones are created quickly and share disk blocks with the original.

Cons
- Sandboxed App Store apps are not supported and are hidden rather than cloned.

FAQ
Can I legally use MacDupl with any app?
MacDupl clones apps that are already installed on your Mac and creates isolated instances with separate logins and data. It is intended for personal use on apps you have locally installed, and some services may have their own rules about multiple simultaneous accounts.
What happens when the original app updates?
MacDupl detects when the original app version changes and regenerates the clone automatically when MacDupl starts and when you click Launch. If you open a clone directly from the Dock or Spotlight while MacDupl is not running, you may briefly get the older copy until MacDupl refreshes it.
Can I try the full version before buying?
Yes. The free trial unlocks the Pro feature set for 7 days. After that, you can keep using MacDupl free with one clone, or buy the one-time Pro license to create unlimited clones.
Does MacDupl work with App Store apps?
Sandboxed App Store apps cannot be cloned because their data lives in a shared container. MacDupl hides those apps rather than producing a broken clone. The supported path is usually the direct-download version of the app, if one exists.
Does MacDupl send usage data anywhere?
No. MacDupl says it has no telemetry and no analytics. The only network requests it makes are license validation and app update checks.
