Halo questions
Short answers. More detail in the Getting started guide.
Is Halo really free?
Yes. Halo is free for Mac with no account, no license key and no subscription. If it helps your shows, you can buy us a coffee.
Why does macOS say it can't verify Halo?
Halo is not notarized by Apple yet, so macOS asks you to confirm the first time. macOS 15 Sequoia or later: double-click Halo, click Done, then System Settings > Privacy & Security > Open Anyway. macOS 14 or earlier: Control-click Halo > Open > Open. Full steps: Open Halo the first time.
Right-click > Open doesn't work on my Mac.
On macOS 15 Sequoia and later Apple removed that shortcut. Use System Settings > Privacy & Security > Open Anyway. You only need to do it once.
macOS says Halo is damaged.
Drag a fresh copy of Halo from the disk image into Applications, then repeat the first-launch step.
Does Halo send my audio anywhere?
No. Speech recognition runs on your Mac with the models built into the app. Halo has no account, no analytics and no cloud AI. See the Privacy Policy.
Does it need the internet?
No. Halo talks to grandMA3 over your local network or on the same Mac. The download is the only time you need the internet.
Which Macs and consoles work?
Apple silicon Macs (M1 or newer) with macOS 12 or later, with grandMA3 onPC 2.5 or a grandMA3 console on the same network. Intel Macs and Windows are not supported yet.
Can Halo change my show file?
No. The HaloSync plugin only reads names. Halo sends only the commands you call, and starts in Dry run so nothing is sent until you turn it off.
Can I use the show caller's feed instead of a mic?
Yes. In Settings > Voice pick your audio interface, Dante Virtual Soundcard or SoundGrid input and the caller's channel.
Can I call from my phone?
Yes. Turn on Phone remote in Settings and scan the QR code. It works on your local network only and is protected by a PIN.
Halo can't hear me.
System Settings > Privacy & Security > Microphone: turn on Halo. Then pick your mic in Halo's Settings > Voice.
Nothing moves on the console.
Dry run is still on, or the OSC line is missing Receive Command or Enable Input. See Getting started step 4.
