First launch

Once
Xynthis is signed but not yet notarized by Apple, so macOS blocks the first launch once. Approve it and you're set.
  1. 1Open the DMG and drag Xynthis to Applications.
  2. 2Open Xynthis. macOS says it can't be opened.
  3. 3In System Settings, go to Privacy & Security and click Open Anyway.
  4. 4Confirm. macOS won't ask again.
  5. 5Paste your license key when Xynthis asks. It's on the License page of your account.
