Hi, When I try to install the latest release (2.2.1) on an M1 MacBook Pro using the GUI installer, I get the error "The operation couldn’t be completed. (com.apple.installer.pagecontroller error -1.) Couldn't open "Phenix-2.2.1-6174-MacOSX-arm64.pkg" I have already removed extended attributes, so that's not the problem. Checking xattr gives this % xattr ~/Downloads/Phenix-2.2.1-6174-MacOSX-arm64.pkg com.apple.macl This is also not a time-out issue; the installer just never launches.
