Building on macOS 10.15 fails. Can't locate Mac/Memory.pm

Which version of electron-builder are you using?

• 20.44.4:

What target are you building for?

• Mac(dmg):

I’m on MacOs 10.15 (beta2). While trying to build dmg I get following exception:

Error: Exit code: 2. Command failed: /usr/bin/perl /private/var/folders/9c/tprqfcrs66qff3x86tdp3_xw0000gn/T/t-yGVUjs/1-dmgProperties.pl

Possible issue with Perl on new Mac OS?

@UdaraJay Thanks a lot. And to whom don’t know how to build pkg instead of dmg, you could edit the package.json:

"build":{
      "mac": {
          "icon": "build/icons/icon.icns",
          "target":"pkg"
       }
}
