This is because my app is not signed, and Apple's developer account is a little expensive for me.You just need to click the Cancel button, then go to the Settings -> Privacy and Security page, click the Still Open button, and then click the Open button in the pop-up window. After that, there will be no more pop-up warnings when opening Pot.

If you cannot find the above options in Privacy & Security, or get error prompts such as broken files with Apple Silicon machines. Open Terminal.app and enter the following command (you may need to enter a password halfway through), then restart Pot:

sudo xattr -d com.apple.quarantine /Applications/pot.app
