At some point I had to renew my Mac App Store certificates, so I've done so, and now that I'm attempting to build for submission to the app store, I'm getting: "No certificate for team 'My Name' matching '3rd Party Mac Developer Application: My Name (MY_ID)' found". But where to get a 3rd Party Mac Developer Application certificate? Under Xcode's "Manage Certificates", there is no "3rd Party Mac Developer Application" under the "+" button. There are only: Apple Development Apple Distribution Mac Installer Distribution Developer ID Application Developer ID Installer (all of which I have).

For years I've been using Receigen for receipt verification for the Mac App Store build of my application. However, with the deprecation of exit code 173, I am moving to StoreKit-based verification and have a couple of questions. I have followed the instructions from https://developer.apple.com/documentation/storekit/apptransaction/shared and have something like this (simplified): Swift: @objc class ValidateReceipt: NSObject { @objc func validate() async -> Bool { do { let verificationResult = try await AppTransaction.shared switch verificationResult { case .verified(_ /*let appTransaction*/): // StoreKit verified that the user purchased this app and // the properties in the AppTransaction instance return true; default: // The app transaction didn't pass StoreKit's verification return false; } } catch { // Handle errors return false; } } } Objective-C: ValidateReceipt *validateReceipt = [[ValidateReceipt alloc] init]; [validateReceipt validateWithCompletionHandler:^(BOOL result) { if (result) { // Successful app purchase validation } else { // App purchase validation failure } }]; Thing is, I always get a valid result, i.e., in ValidReceipt.validate(), the case .verified block always runs. Even when exporting a new release build of my app and running it (without any _MASReceipt). When using exit code 173, an .app without a _MASReceipt would prompt for app store login. Nothing of the sort happens now. Am I misunderstanding the documentation / doing something wrong / missing something obvious?
