How to sign and notarize a macOS app with Conveyor

Pre-reqs

• On a mac (possibly not needed, but I didn't test on windows/linux)
• Want a notarized mac app (self-distribution, not on mac app store, although it may still work for mac app store, not sure)
• Need an apple dev account ($100 a year)
• Integrate conveyor via these instructions https://conveyor.hydraulic.dev/17.100.1/tutorial/tortoise/2-gradle/ and this sample https://github.com/hydraulic-software/compose-multiplatform-starter

1. Go to ~/Library/Preferences/Hydraulic/Conveyor/ Inside of that folder there will be apple.csr

Source: https://conveyor.hydraulic.dev/17.0/running/#initial-setup-and-default-config

1. Go to https://developer.apple.com/account/resources/certificates/add and click "Developer ID Application". The page will now show you two different certs. It seems like an "older" cert format is auto-selected, but the new one works and has a longer expiration.

1. Apple will give you a .cer. Place it somewhere (I just put it in my Conveyor Prefs directory)

2. Now you need an api key to use apple's notarization service. Go to https://appstoreconnect.apple.com/access/integrations/api and create it with the "Developer" role.

Source: https://conveyor.hydraulic.dev/17.0/configs/keys-and-certificates/#configure-apple-notarization

Your final defaults.conf:

# Your private root key, from which all other generated keys are deterministically derived.
app.signing-key = "keyring"

# Credentials needed for the macOS app approval process.
 app.mac.notarization {
   issuer-id = abc-123-123-123-ABC123
   key-id = ABC123123
   private-key = /Users/cidle/Library/Preferences/Hydraulic/Conveyor/AuthKey_ABC123.p8
 }

app.mac.certificate = /Users/cidle/Library/Preferences/Hydraulic/Conveyor/cert_from_apple.cer

Note: Even though the docs make it seem like you might need app.mac.signing-key, you do not.

Note 2: app.mac.certificate can be a relative path (to the defaults.conf) it doesn't have to be absolute
