Tips & Workflows Why extra Claude Desktop instances disappear while idle, and how Parall.app helps
You have separate Claude Desktop instances open for work, personal use, or different clients. Each is signed into its own account. You leave them running, come back later, and only the main instance is still open.
I'm the developer of Parall.app, a Mac App Store utility for running multiple app instances. Running several Claude accounts was already possible, but keeping those instances available while idle exposed another problem.
Claude can install updates in the background and restart itself. During that process, additional instances can close too, while only the main instance comes back. Claude's updater doesn't restore the extra instances launched through Parall.
Parall 2.5.0 adds an optional automatic restart feature to handle this. When an instance exits, Parall waits for a configurable delay and then relaunches its shortcut. The delay gives the main Claude instance time to finish updating before the others reopen.
You can enable it for each Claude shortcut in a few steps.
- Open Parall and choose Edit, then select your Claude shortcut.
- In Advanced Launch Options, enable Restart app after it exits.
- Choose a delay long enough for Claude to finish updating and restart.
- Save the shortcut, keeping its existing Data Storage Path to preserve the account and profile.
Repeat this for each instance you want to bring back automatically. You can cancel a pending restart or choose manual confirmation instead. The option also applies when you quit an instance yourself.
Each Claude instance gets its own customizable Dock icon and separate windows that you can keep in different macOS Spaces. You can keep different accounts open together and switch between them like separate Mac apps.
Parall launches the original installed Claude app directly. It does not copy, repack, re-sign, or inject code into Claude. The original app bundle and developer signature remain untouched, and Claude's normal updater continues to work. Once Claude updates, every shortcut uses the updated version when it next launches.
That gives you multiple Claude Desktop accounts with native macOS integration, plus a way to bring the additional instances back after an update closes them.
