Hello I am looking at taking advantage of managing some features via DDM in an app. I noticed in the ServicesConfigurationFiles link (https://developer.apple.com/documentation/devicemanagement/servicesconfigurationfiles) it says You can create an executable that uses service configuration files by calling the mcf_service_path_for_service_type method in the libmanagedconfigurationfiles.dylib system library. You pass in an identifier for your service type and the method returns the file system path for the directory that contains the corresponding service configuration files. Use those files to override the standard or default configuration the executable would otherwise use. See libmanagedconfigurationfiles.h in the macOS SDK for more detail. I can't find any more references or information on mcf_service_path_for_service_type, libmanagedconfigurationfiles.dylib or libmanagedconfigurationfiles.h anywhere. Is there any information somewhere about this? Or how to use it? Or a POC small example?

I am interested in managing some configuration files for an app using Declarative Device Management (DDM) and noticed a blurb on the ServicesConfigurationFiles developer page that makes it seem like 3rd party apps can take advantage of DDM service files. But I'm not exactly sure how https://developer.apple.com/documentation/devicemanagement/servicesconfigurationfiles You can create an executable that uses service configuration files by calling the mcf_service_path_for_service_type method in the libmanagedconfigurationfiles.dylib system library. You pass in an identifier for your service type and the method returns the file system path for the directory that contains the corresponding service configuration files. Use those files to override the standard or default configuration the executable would otherwise use. See libmanagedconfigurationfiles.h in the macOS SDK for more detail I can't find any more details in the developer documentation on this. How would this be used? Could someone give an example or small POC?

I've been spending days trying to solve the memory leak in a small menu bar application I've wrote (SC Menu). I've used Instruments which shows the leaks and memory graph which shows unreleased allocations. This occurs when someone views a certificate on the smartcard. Basically it opens a new window and displays the certificate, the same way Keychain Access displays a certificate. Whenever I create an SFCertificateView instance and set setDetailsDisclosed(true) - a memory leak happens. Instruments highlights that line. import Cocoa import SecurityInterface class ViewCertsViewController: NSViewController { var selectedCert: SecIdentity? = nil override func viewDidLoad() { super.viewDidLoad() self.view = NSView(frame: NSRect(x: 0, y: 0, width: 500, height: 500)) self.view.wantsLayer = true var secRef: SecCertificate? = nil guard let selectedCert else { return } let certRefErr = SecIdentityCopyCertificate(selectedCert, &secRef) if certRefErr != errSecSuccess { os_log("Error getting certificate from identity: %{public}@", log: OSLog.default, type: .error, String(describing: certRefErr)) return } let scrollView = NSScrollView() scrollView.translatesAutoresizingMaskIntoConstraints = false scrollView.borderType = .lineBorder scrollView.hasHorizontalScroller = true scrollView.hasVerticalScroller = true let certView = SFCertificateView() guard let secRef = secRef else { return } certView.setCertificate(secRef) certView.setDetailsDisclosed(true) certView.setDisplayTrust(true) certView.setEditableTrust(true) certView.setDisplayDetails(true) certView.setPolicies(SecPolicyCreateBasicX509()) certView.translatesAutoresizingMaskIntoConstraints = false scrollView.documentView = certView view.addSubview(scrollView) // Layout constraints NSLayoutConstraint.activate([ scrollView.leadingAnchor.constraint(equalTo: view.leadingAnchor), scrollView.trailingAnchor.constraint(equalTo: view.trailingAnchor), scrollView.topAnchor.constraint(equalTo: view.topAnchor), scrollView.bottomAnchor.constraint(equalTo: view.bottomAnchor), // Provide certificate view a width and height constraint certView.widthAnchor.constraint(equalTo: scrollView.widthAnchor), certView.heightAnchor.constraint(greaterThanOrEqualToConstant: 500) ]) } } https://github.com/boberito/sc_menu/blob/dev_2.0/smartcard_menu/ViewCertsViewController.swift Fairly simple.
