You'll see a security warning

Aethis isn't signed with an official certificate, so your computer will show a warning when you try to open it. This is normal for indie software — here's how to proceed:

  • macOS: You'll see "Aethis can't be opened because Apple cannot check it for malicious software." Go to System Settings → Privacy & Security and click "Open Anyway".
  • Windows: You'll see "Windows protected your PC" from SmartScreen. Click "More info" then "Run anyway".

Signing certificates cost several hundred dollars per year. Since Aethis is free during the pre-release phase, it's distributed unsigned. The code is open for review on GitHub.
