Today dowloaded electrum-4.4.6.dmg fails on signature verification with electrum-4.4.6.dmg.asc. Both files from https://electrum.org/#download. I use GPG Keychain v.1.12 on macOS 13.5.2 (22G91). Files for version 4.0.9 pass verification.

Update: I found public keys of SomberNight and Emzy. Now verification is ok.
