How do you send an NSURL representing a new file, as returned from an NSSavePanel, to an XPC service such that the service is granted permission to create the file? I can successfully pass an NSURL to the XPC process if the NSURL represents an existing file. This is documented in Apple's Documentation: Share file access between processes with URL bookmarks This involves creating bookmark date while passing 0 in as the options. However, if you try to create bookmark data for an NSURL that represents a file that is not yet created, you do not get any bookmark data back and an error is returned instead: Error Domain=NSCocoaErrorDomain Code=260 "The file couldn’t be opened because it doesn’t exist." Simply passing the file path to the XPC process, by way of: xpc_dictionary_set_string(message, "file_path", url.fileSystemRepresentation); Does not grant the XPC create/write permissions. Is there an API or trick I'm missing? Note that the user should be allowed to save and create new files anywhere of their choosing, thus restricting URLs to only those within a group or container shared between the app and service isn't really viable. Using the latest of everything on macOS with the xpc_session API...

Filed as rdar://FB11975037 When macOS Ventura is run as a guest OS within the virtualization framework, the main menu bar items will not be displayed correctly if VZMacGraphicsDisplayConfiguration defines a large resolution. The menu bar titles appear to be using the same color as the menu bar itself. When the Appearance is set to Light, the menu bar items are effectively invisible. When the Appearance is set to Dark, the menu bar items are drawn in what looks like a disabled state. This only affects the menu bar item titles on the left-hand side. The date-time and menu bar icons on the right side are always displayed in the correct color. This appears to be a regression in macOS Ventura as this issue is not present in macOS 12 running as a guest. This bug can be easily reproduced using Apple's own Virtualization sample code titled: "Running macOS in a Virtual Machine on Apple Silicon Macs" Steps to reproduce: Follow the sample code instructions for building and installing a VM.bundle. Before running 'macOSVirtualMachineSampleApp', change the VZMacGraphicsDisplayConfiguration to use: width = 5120, height = 2880, ppi = 144. Run 'macOSVirtualMachineSampleApp' and notice that the menu bar titles on the left side of the screen are not correctly drawn in the guest instance. This has been tested on: Host: macOS 13.1 Guest: macOS 13.x (All versions) Hardware: MBP 14" M1 Pro 32GB/2TB Is there anything that can be done to resolve this issue?

The new Virtualization framework (and sample code!) are great. It's a lot of fun to run the sample code and quickly fire up multiple VMs of macOS running as a guest. However, the inability to authenticate with any iCloud services is a significant roadblock. Xcode, for example, is not allowing me to authenticate my developer account. Are there any plans to resolve this issue so that iCloud accounts can be authenticated from within a VM?

In WWDC21 session 10233: Bring Encrypted Archives and Performance Improvements to Your App with Accelerate, there is an example of encrypting a directory using the AppleArchive framework. There is also accompanying sample code. However, that sample code uses a SymmetricKey and the hkdf_sha256_aesctr_hmac__symmetric__none profile. The key is set by calling context.setSymmetricKey(encryptionKey). How can you perform the same operation of encrypting a directory using AppleArchive but with a "human" password? (i.e.: A password provided by the user from a prompt?) Simply changing the profile to hkdf_sha256_aesctr_hmac__scrypt__none and then calling `context.setPassword("MyPassword") producing the following output "Error setting password (invalidValue)." I also tried using the command line aea application, but received the output Password is too short. Prompt: > aea encrypt -v -password-value "password" -profile 5 -i MyDirectory -o MyDirectory.aea Operation: encrypt input: FOO output: FOO.aea profile: hkdf_sha256_aesctr_hmac__scrypt__none worker threads: 10 auth data (raw): 0 B compression: lzfse 1 MB Error 0xb9075800 Password is too short Main key derivation failed (-2) Main key derivation Invalid encryption parameters Finally, in the file AEAContext.h, there is a comment associated with the method AEAContextSetPassword() that states: Set context password Stores a copy of password in context. Required to encrypt / decrypt a stream when encryption mode is SCRYPT. An internal size range is enforced for the password. The caller is expected to enforce password strength policies. @param context target object @param password password (raw data) @param password_size password size (bytes) @return 0 on success, a negative error code on failure I cannot find any other documentation that states what the password policy. And if there is a password policy for AppleEncryptedArchives, does that mean AEA is not a good fit for encrypting personal directories where the user just wants to use "any old password", regardless of the password's strength?

In a triple-column split view, it's common to hide the primary view when the user selects an item from a list. In some cases, the supplemental view is also hidden when an item is selected from that list, thus leaving only the detail view visible. What is the correct way to hide the primary view on selection and then to optionally hide the supplemental view on selection using the new NavigationStack? (Notes is a good example of the sidebars hiding after the user selects a folder in the sidebar.)

I'm trying to use an NSImage that represents an SF Symbol as the contents of a CALayer. NSImage has an API for this in the form of [NSImage layerContentsForContentsScale:]. On the NSImage documentation page, there's even a few paragraph at the top dedicated to using this very method. But how do you set the color you want the image to render as if the image is an SF Symbol? NSImageView has .contentTintColor which works great, but CALayer has no such property. final class SymbolLayer: CALayer { func display() { // Just an example... let image = NSImage(systemSymbolName: "paperclip", accessibilityDescription: nil)! let actualScaleFactor = image.recommendedLayerContentsScale(contentsScale) // This obviously produces a black image because there's no color or tint information anywhere.     contents = image.layerContents(forContentsScale: actualScaleFactor) } } Is there a way you can configure the CALayer or the NSImage itself to have some sort of color information when it generates the layer contents? I've attempted to play around with the SymbolConfiguration coolers but without any success. (Even when wrapped inside NSAppearance.performAsCurrentDrawingAppearance.) The best I can come up with is to use CALayer.draw(in:) and then use the old NSImage.cgImage(forProposedRect:...) API. I can then set the fill color on the CGContext and go from there. Is there a more efficient way? override func draw(in context: CGContext) { let image = NSImage(systemSymbolName: "paperclip", accessibilityDescription: nil)!   var rect = bounds image.size = bounds.size let cgImage = image.cgImage( forProposedRect: &rect, context: nil, hints: [.ctm: AffineTransform(scale: contentsScale)] )! NSApp.effectiveAppearance.performAsCurrentDrawingAppearance { // Draw using an Appearance-sensitive color.     context.clip(to: bounds, mask: cgImage)     context.setFillColor(NSColor.labelColor.cgColor)     context.fill(bounds)   } } This is for macOS 12+.
