macOS First-launch Blocks
If macOS blocks launch, confirm that the app came from the official release page, then re-open the system prompt path instead of repeatedly downloading the same file.
Windows SmartScreen Prompts
If SmartScreen appears, verify the source and checksum first. Only continue once the installer origin is confirmed.
Reinstall Cleanly
When install state looks inconsistent, remove the partial install, download again from the release page, and repeat the install flow without mixing old and new archives.
