The docs here outline how to create a CSR/ and request a certificate.
https://developer.apple.com/help/account/certificates/create-a-certificate-signing-request
"Accounts preferences
Use Accounts preferences to manage developer account assets (signing certificates and provisioning profiles), add repositories, and add servers.
To open Accounts preferences, choose Xcode > Preferences and click Accounts."
I have the latest version of XCode, I don't see Preferences / Accounts anywhere? I can go here and create a certificate: https://developer.apple.com/account/resources/certificates/add
but it wants a CSR, which loops back around to the XCode thing. So, I can't figure out how to create a singing cert for my iOS app.
Launch Keychain Access located in /Applications/Utilities.
This doesnt seem to exist in Mac OS Sequoia 15.5
