All platforms

Not sure which Mac you have? Choose Apple menu, About This Mac: Chip means Apple Silicon, Processor means Intel. The SHA-256 checksum of every file is in SHA256SUMS.txt.

Install

Two minutes, then you're in.

On a Mac

  1. Open the downloaded .dmg and drag Halo by Synquic into Applications.
  2. In Applications, right-click (or Control-click) Halo by Synquic, choose Open, then choose Open again in the dialog.
  3. If macOS still refuses, open System Settings, Privacy & Security, scroll down and click Open Anyway next to the message about Halo, then confirm.
  4. You only do this once. After that, Halo opens normally.

Why the warning: Halo is not yet signed with an Apple Developer ID certificate, so Gatekeeper cannot confirm who made it. Download Halo only from this site or the official releases page.

On Windows

  1. Run Halo-win-x64.exe from your Downloads folder.
  2. If Windows protected your PC appears, choose More info, then Run anyway.
  3. Follow the installer. You can choose the folder Halo installs into.
  4. Open Halo by Synquic from the Start menu.

Why the warning: the installer is not yet signed with a Windows code-signing certificate, so Microsoft Defender SmartScreen does not recognise it. Download Halo only from this site or the official releases page.

System requirements

  • macOS 12 Monterey or later, on Apple Silicon or Intel.
  • Windows 10 or 11, 64-bit.
