Starting with v3.8.0, the macOS version will ship unsigned

Unfortunately, I can no longer pay for the Apple Developer Program in order to sign applications, I simply don't have a way to pay. Therefore, starting with version 3.8.0, the macOS version will ship unsigned.

Launching the application:

1. Go to System Preference
2. Click Security & Privacy
3. Select the Allow button under the Allow apps downloaded from section

No problem, just don't stop building it cause its an absolute gem.
And thanks for everything.

On macOS 15.2, you can open the app by first trying to launch it (it will be blocked) and then going to the settings Privacy & Security to click “Open Anyway.”

Previously, it used to show the "Open Anyway" button for blocked applications. But, I'm not able to find it now.
I'm on macOS Tahoe Version 26.0.1 (25A362).

Edit: Nevermind! The Option 2 from troubleshoot section helped me.
