One Mac.
Every account, its own app.
MacDupl clones the desktop apps you already use into fully isolated instances — separate logins, separate data, separate Dock icons. Work and personal, side by side. No more logging out.
7-day free trial · macOS 13+ · Apple Silicon & Intel · Notarized by Apple
Real second instances,
not browser-tab workarounds.
Each clone is a genuine macOS app with its own identity — the original stays untouched and independently launchable.
Instant clones
Pick an app, name the instance, choose a color. MacDupl builds the clone in ~2 seconds and it launches instantly after that.
Nearly free on disk
Clones are APFS copy-on-write duplicates: a 700 MB app costs almost nothing extra — the copies share disk blocks with the original.
True isolation
Every instance keeps its own logins, cookies, caches and preferences. Credentials never leak between clones — or into the shared Keychain.
Its own Dock icon
Each clone gets a color-tinted, badged icon and a real identity in the Dock, Launchpad and app switcher. You always know which one is which.
100% private
No telemetry, no analytics, no cloud. Everything happens on your Mac — the only network calls are license checks and app updates.
Easy to manage
Launch, stop, reset a session, recolor, or delete any instance from one dashboard. MacDupl keeps itself updated with signed automatic updates.
Three clicks to a second instance.
No configuration files, no command line, no browser profiles.
Pick an app
MacDupl scans your Applications folder and shows everything it can clone, classified automatically.
Name & color it
"Work", "Personal", "Client X" — choose one of nine icon tints so the Dock never gets confusing.
Hit Create
About two seconds later there's a new app in your Dock with its own login, ready to sign in to your second account.
Built for the apps you actually use.
MacDupl detects each app's engine and applies the right isolation strategy automatically.
| App family | Examples | Support |

| Chromium browsers | Chromium-based browsers | Full isolation, separate profiles |
| Firefox family | Gecko-based browsers and mail clients | Full isolation via dedicated profiles |
| Native apps BETA | Everything else | Isolated home directory; sandboxed App Store apps may not work |

Questions, answered.
Is this allowed by the apps I clone?
MacDupl only duplicates apps that are already installed on your Mac, locally, for your own use — nothing is redistributed or modified on any server. Some services have their own rules about multiple simultaneous accounts, so it's your responsibility to comply with the terms of the apps you clone.
What happens when the original app updates?
Clones are snapshots of the app at the moment you created them. When the original updates, open the clone's Edit sheet and hit Save — MacDupl regenerates the clone from the new version while keeping your login and data intact.
Why does a clone ask for microphone / screen permissions again?
Because each clone is a genuinely separate app in macOS's eyes, the system asks for permissions once per clone. That's the flip side of real isolation — the same mechanism that keeps your accounts from leaking into each other.
Does it work with App Store apps?
Apps that rely on the App Store sandbox may not launch as clones — cloning is marked beta for native apps. Electron apps, Chromium browsers and the Firefox family — where multi-account pain is worst — are fully supported.
Is any of my data sent anywhere?
No. MacDupl has no telemetry and no analytics. The only network requests it ever makes are validating your license key and checking for app updates.
How much disk space do clones use?
Almost none. Clones are APFS copy-on-write duplicates that share their disk blocks with the original app. Only each instance's own data (logins, cache) takes real space.
What are the system requirements?
macOS 13 Ventura or later, on Apple Silicon or Intel. MacDupl is signed and notarized by Apple.
