First launch on macOS

If macOS says SquirrelDisk “can't be opened” or “is damaged”, it's because the app is distributed outside the App Store. Either:

  1. Open System Settings → Privacy & Security, scroll down and click Open Anyway next to the SquirrelDisk message, then confirm.
  2. Or run this in Terminal, then open SquirrelDisk again:
xattr -dr com.apple.quarantine /Applications/SquirrelDisk.app

On recent macOS versions, right-click → Open is no longer enough.

First launch on Windows

If “Windows protected your PC” appears, click More info, then Run anyway.

For the portable .exe you can also right-click the file → Properties → tick Unblock → OK.
