Install on Mac

Halo runs on macOS 12 Monterey or later, on Apple Silicon and Intel Macs.

Pick the right download

Choose Apple menu, About This Mac. If you see Chip (for example Apple M1 or later), download Halo-mac-arm64.dmg. If you see Processor with an Intel name, download Halo-mac-x64.dmg. Both are on the download page.

Install

1. Open the downloaded .dmg.
2. Drag Halo by Synquic into the Applications folder.
3. Eject the disk image.

Open Halo the first time

Halo is not yet signed with an Apple Developer ID certificate, so macOS cannot confirm who made it and blocks a normal double-click the first time.

1. Open Applications in Finder.
2. Right-click (or Control-click) Halo by Synquic and choose Open.
3. Choose Open again in the dialog.

If macOS still does not offer to open it:

1. Open System Settings, then Privacy & Security.
2. Scroll down to the message about Halo by Synquic and click Open Anyway.
3. Confirm with your Mac password or Touch ID, then choose Open.

You only need to do this once. Download Halo only from this website.

Permissions Halo may ask for

• Keychain: Halo stores your session and your account key in the macOS Keychain, so it opens without typing anything. When you import passwords from another browser, macOS may ask to allow access to that browser's Keychain entry.
• Microphone: only when you turn on voice in Halo AI. Speech is transcribed on your Mac.

Update or uninstall

To update, download the latest version and replace the app in Applications. To uninstall, drag Halo by Synquic from Applications to the Trash. Your encrypted vault stays in your Halo account and comes back when you sign in again.
