Installation, Usage, and Compatibility

Step‑by‑step installation:

1. Visit the official Koala website and click the “Download for Mac” button.
2. The DMG file will appear in your Downloads folder; double‑click to mount it.
3. Drag the Koala icon into the Applications folder shortcut shown in the installer window.
4. Launch Koala from the Applications folder or Spotlight search.
5. On first launch, macOS may prompt you to confirm that you trust the developer—select “Open” to proceed.
6. Sign up with an email address or use an existing Koala account to start chatting.

First‑time configuration: After logging in, Koala walks you through a quick setup wizard. You can import contacts from your macOS address book, customize your avatar, and choose your preferred theme. The notification panel lets you set “Do Not Disturb” periods, ensuring that alerts only appear when you want them.

System requirements: Koala runs on macOS 10.13 (High Sierra) and later, including macOS Ventura and the latest Apple Silicon builds. The app is universal, meaning it runs natively on both Intel‑based and M1/M2 Macs without emulation, delivering consistent performance across devices.

Usage tips for power users: Take advantage of keyboard shortcuts such as ⌘+N for a new chat, ⌘+F to search within a conversation, and ⌘+Shift+M to mute a specific thread. The “Quick Send” pane lets you drop files directly onto the chat window, automatically generating a preview thumbnail. For teams, the “Pin” feature keeps important messages at the top of a group chat, reducing the need to scroll back for key information.
