Parall is the first and only macOS app that lets you run multiple instances of any app - natively and without hacks. Create independent macOS app shortcuts with unique data, environment variables, command line arguments and HOME overrides. Each shortcut behaves like a standalone app with its own Dock icon and settings. Works fully offline, privacy-friendly, and ideal for Chrome-based browsers, Firefox, Slack, Notion, VS Code, Dropbox, Discord and more. Parall is now live in the Mac App Store.

DockLock Lite stops the macOS Dock from jumping between screens. Lock it in place, choose allowed displays, or temporarily unlock movement with a key. No system hacks, just a simple fix for a decade-old annoyance. Try for free, upgrade for full control.
