TapNoise has no Check for Updates button. It looks for a newer version by itself, about once a day, and keeps the answer until the next check.
When an update is out
When a newer version is available, the menu shows Download TapNoise with its version number, above Settings…. Click it to open the download in your browser.
Install the update
- Open the download and drag TapNoise into Applications, replacing the older copy.
- Open TapNoise from Applications. macOS may ask you to confirm once more. See Open Anyway.
- If an agent now says it has moved, click Repair in Settings › Agents. See repair an agent that says moved.
Your license covers every update, so you don’t need a new key.
If the menu doesn’t show Download TapNoise, TapNoise hasn’t seen a newer version yet. It checks again about a day later, and only while it’s online.
