Hi @juanlopez4691, thanks for reporting this!

The macOS build is currently in beta and is not yet signed with an Apple Developer ID certificate, so macOS Gatekeeper flags it as "damaged."

Workaround:

After dragging AeroFTP to Applications, open Terminal and run:

sudo xattr -rd com.apple.quarantine /Applications/AeroFTP.app

Then launch the app normally. Keep in mind that you may still experience some instability since the macOS version has not been fully tested yet.

Why this happens: AeroFTP is an open-source project and does not currently have an Apple Developer ID certificate. The app is cryptographically signed via Sigstore for supply-chain integrity, but macOS Gatekeeper requires Apple's own code signing to let apps launch without warnings.

We are actively working on full Apple support (code signing + notarization) and hope to have it ready soon. In the meantime, if you need a fully stable experience, feel free to try AeroFTP on Linux (.deb, Snap, AUR) or Windows (.msi) where everything is well tested.

Thanks for your patience, and sorry for the trouble!
