What helps
For a technical issue, include:
- your macOS version and Onlink version;
- which area was involved — Internet Health, Diagnose, History, reports, alerts, or a speed test;
- the exact message or behavior you saw;
- whether a VPN, captive portal, or unusual network setup was active, when relevant.
Screenshots can help, but remove or hide public IP addresses or anything else you would rather not share. Never send passwords, authentication codes, or private network credentials.
