Halo v1.0.2

Halo v1.0.2 — tidier window previews.

What's new

• Cleaner preview layout. When you fan out an app's window previews, they now tile in a compact, screen-aligned grid with uniform spacing, instead of spreading along a diagonal that changed with the icon's position on the ring. The arrangement is consistent for every spot around the ring and stays on-screen (1 window → single card, 2 → a row, 3–4 → 2×2, 5–6 → 3×2, and so on).

Update

Already on Halo? Click the menu-bar icon → Check for Updates… and it'll download and relaunch into this version. Or grab Halo.app.zip below.

Requires macOS 26 (Tahoe) on Apple Silicon. Not Mac App Store eligible (self-build / sideload only).

macOS says it "could not verify Halo is free of malware"?

That's expected for a downloaded Halo.app.zip — the release is signed with an Apple Development certificate, not a notarized Developer ID one, so Gatekeeper blocks the first launch. Two ways past it:

1. Terminal (recommended). Move Halo.app to /Applications, then strip the quarantine flag:

   xattr -dr com.apple.quarantine /Applications/Halo.app

   This also prevents Gatekeeper App Translocation, which would otherwise break the permission grants and the in-app updater.
2. System Settings. Try to open Halo once (let it get blocked), then go to System Settings ▸ Privacy & Security, scroll down to the "Halo was blocked" notice, and click Open Anyway. (On macOS 26 the old right-click ▸ Open bypass no longer works for unnotarized apps.)
