Installing
Two clicks, once.
Kynd Agent installs by dragging it to Applications, like anything else. The first time you open it macOS will stop and ask — here is exactly what it says, what to click, and why it happens at all.
Handed a copy on a USB stick or external drive? Then none of this applies to you. Drag it to Applications and open it — the warning below only appears on copies downloaded through a web browser.
-
Drag it to Applications
Open the .dmg you downloaded. A window appears with the Kynd Agent heart on the left and your Applications folder on the right. Drag one onto the other, then eject the disk image.
-
Open it the first time
Double-click Kynd Agent. macOS will say it cannot verify the developer. This is expected, and it is not an error — it is macOS telling you the app has not been through Apple's paid signing programme. Which path you take depends on your macOS version:
macOS 15 Sequoia and later
Click Done on the warning. Open System Settings → Privacy & Security, scroll to the bottom, and click Open Anyway next to the message about Kynd Agent. Confirm once more.
macOS 13 and 14
Control-click (or right-click) Kynd Agent in Applications and choose Open from the menu, then Open again in the box that appears.
-
That is the last you will see of it
macOS remembers your answer. Every launch after the first one opens straight away, and updates from inside the app do not ask again.
Why does it ask at all?
Honestly? Because Kynd Agent is not signed with an Apple Developer certificate yet.
That certificate costs $99 a year and requires registering as an identified developer with Apple. Kynd Agent is built by one person, and that has not been bought yet. Until it is, macOS treats the app the way it treats anything it has not seen a certificate for: it asks you first.
It is worth knowing what the warning does and does not mean. It does not mean macOS found anything wrong with the app — it means macOS cannot confirm who wrote it. The download itself is served over HTTPS from this site, and the app is checksummed, so if you want to verify you got the real thing you can compare the SHA-256 in latest.json against your download.
If it says "damaged" instead
A copy that says "Kynd Agent is damaged and can't be opened" has usually had its quarantine flag mangled in transit — by a download manager, or by being passed through a file-sharing service. Re-downloading from the download link fixes it in almost every case. If it persists, this one line in Terminal clears the flag by hand:
xattr -dr com.apple.quarantine "/Applications/Kynd Agent.app"
That command removes the "downloaded from the internet" marker on that one app and nothing else. You should be sceptical of any website telling you to paste commands into a terminal — including this one — so it is here as a last resort, not the normal route.
