Tether 1.5.1

🔄 Tether now updates itself

• Tether checks for a new version once a day and lets you know with a notification. Choose Tether › Check for Updates… to check now, or turn automatic checks off in Settings › About.
• Updates download, verify and install in place, then Tether relaunches. Nothing to drag, and no Gatekeeper prompt.
• Every release is now signed with the same certificate, and Tether only installs an update signed with that certificate. A tampered or substituted download is refused.

🍺 Homebrew

• Install with brew install --cask subhashhhhhh/tether/tether. Homebrew installs skip the "can't be opened" warning.

🔐 Accessibility permission sticks

• Because every release has the same signature, macOS now remembers Tether's Accessibility permission (used for Remote Input and Presentation) across updates. You'll need to grant it once more after installing 1.5.1.

Updating from 1.5 or earlier: those versions can't update themselves, so download 1.5.1 (or install it with Homebrew) this one time. Every release after this installs itself.

⬇️ Install

Homebrew (recommended; no Gatekeeper prompt):

brew install --cask subhashhhhhh/tether/tether

Or download the disk image for your Mac:

• Apple Silicon (M1 and later): Tether-1.5.1-AppleSilicon.dmg
• Intel: Tether-1.5.1-Intel.dmg

Not sure which you have? Apple menu → About This Mac → Chip (Apple Silicon) or Processor (Intel). Tether needs macOS 15 Sequoia or later.

Tether is open source and isn't notarized by Apple, so the first time you open a downloaded copy macOS blocks it. Open System Settings → Privacy & Security, scroll to Security and click Open Anyway, or run:

xattr -cr /Applications/Tether.app

Already on Tether 1.5.1 or later? It updates itself from Tether › Check for Updates…
