Opening the macOS beta
The macOS beta builds are for Apple Silicon (M1 or later) only. They are not signed or notarized yet, so macOS blocks the first launch. To open an app:
- Open the .dmg and drag the app to Applications.
- Open the app once. macOS stops it.
- Open System Settings, then Privacy & Security, and click Open Anyway.
- If macOS says the app is damaged and can’t be opened, run this in Terminal, then open the app again:
xattr -dr com.apple.quarantine "/Applications/Post.app" xattr -dr com.apple.quarantine "/Applications/Flock.app" xattr -dr com.apple.quarantine "/Applications/Loft.app" xattr -dr com.apple.quarantine "/Applications/Migrate.app" xattr -dr com.apple.quarantine "/Applications/Pidgeon.app"
Verify your download
Recompute the SHA-256 of the file you downloaded and compare it to the checksum on the button. If they do not match, the download is corrupt or tampered and must not be run.
# macOS / Linux shasum -a 256 <downloaded-file> # Windows (PowerShell) Get-FileHash <downloaded-file> -Algorithm SHA256
