exiftool install instructions for macOS Package .pkg might need updating because in macOS Sequoia 15 the old workaround to open an unnotarized app via control-click > Open does not work anymore.
The official way is to dismiss the alert with "Done", and open System Settings > Privacy & Security > Security and click Open Anyway and proceed to install.

Removing the quarantine flag continue to work:
xattr -d com.apple.quarantine ExifTool-13.00.pkg
exiftool -XAttrQuarantine= ExifTool-13.00.pkg
It would be possible to allow apps from "Anywhere" via a Terminal command but that is a security hole I'd not recommend.

Thanks. I still plan on properly signing ExifTool if I can, but I haven't found time to work on this.

I've finally updated the install page. I did have a go at getting the app signed, but didn't make it very far before I gave up. :(
