Run two Claude accounts on Mac
Run Work and Personal Claude accounts side by side — two real apps, two logins, two Dock icons, both signed in permanently.
7-day free trial · $19 once · macOS 13+ · notarized by Apple
What you get
- Separate accounts. Each instance holds its own Claude login and its own conversation history.
- Separate plans. Keep a work subscription and a personal account open at the same time.
- Cowork runs in instances. A Claude instance can run Cowork — the instance's signature preserves the macOS virtualization entitlement it needs.
- Its own Dock icon. Colour-tinted, so the right account is one click away.
Verified hands-on. Cowork support in instances is verified as of MacDupl 0.1.11 — on 0.1.10 and earlier, opening Cowork in an instance reported that Claude's installation looked corrupted. If you hit that, update MacDupl rather than reinstalling Claude; the instance rebuilds itself on next launch.
- Cowork support verified as of MacDupl 0.1.11 — on 0.1.10 and earlier it reported the installation as corrupted.
- An instance's code signature preserves the macOS virtualization entitlement that Cowork specifically needs.
How to set it up
- Pick the app
Open MacDupl and choose Claude from the list of apps installed on your Mac. - Name and colour it
Call it “Work”, “Personal” or a client's name, and give it one of nine icon tints. - Hit Create
About two seconds later there's a new Claude in your Dock — sign into the second Claude account — Cowork and conversation history stay isolated per instance.
Questions about Claude
Does Cowork work in a cloned Claude?
Yes, as of MacDupl 0.1.11. Cowork needs macOS virtualization, and the instance's signature preserves the entitlement that requires. If you see a “Claude's installation appears to be corrupted” message, you're on an older MacDupl — update it.
Can I use a different plan in each?
Yes. Each instance signs into its own Claude account, whatever plan that account is on.
Is my conversation history shared?
No. Each instance has its own isolated data, so history and settings stay separate.
What about Claude Code?
That's a separate answer: clone VS Code and the Claude Code extension inside each instance holds its own Claude account. See the VS Code page.
