We'd like to use a custom setup for our new students via a modified User Template folder. On macOS 14 the new user template is located at /Library/User Template/Non_localized I can add e.g. another folder here (as "root"): drwxr-xr-x 2 root wheel 64 8 Apr 13:58 newFolder And when a new user is created this folder is added to users homedir, as expected. But this folder has an additional unexpected ACL: $ ls -lde newFolder drwx------+ 2 newuser staff 64 8 Apr 13:59 newFolder 0: group:everyone deny delete Is there any documentation about the user template handling for current macOS versions? We are specially interested in How are ACLs added Predefining standard preferences (e.g. connected servers are visible on desktop) Ayn clue here?

We are used to use a SMB-based network homedir for students in our labs. Unfortunately this does no longer work with current macOS versions (Apple case 101442640823). Therefore we need a workaround. My idea is to use a standard user account which is reseted daily. Therefore I created "USER" and made the initial setup after the first login. My plan was to create a tar-active and a launchdaemon script which does remove /Users/USER and extract the tar archive to get a fresh USER home. This does not work: I cannot remove as root the old home dir via "rm -rf /Users/USER" due to permission errors. I want not remove and re-create the user via dscl because the initial first login setup should not be needed every day. I want to reset USERS home to an archived backup of a defined status. Any clue how to solve this issue?

I have an animation depending on a range. When the end is reached the value is reseted to 0. Unfortunately I get a "rollback" animation which looks very bad but I have no idea how to handle it. Here is a sample code: import SwiftUI let clockTimer = Timer.publish(every: 1, on: .main, in: .common).autoconnect() struct ContentView: View { static func getSecond(_ d : Date) -> Int { let dc = Calendar.current.dateComponents([.second], from: d) guard let s = dc.second else { fatalError("Can't get value!") } return s } @State var s = ContentView.getSecond(Date()) var body: some View { ZStack { Rectangle() .fill(.white) .frame(width: 200.0, height: 200.0) Rectangle() .fill(.red) .frame(width: 80.0, height: 1.5, alignment: .center) .offset(CGSize(width: 50, height: 0)) .rotationEffect(Angle(degrees: 360.0 / 60.0 * Double(s) - 90.0)) .animation(.smooth, value: s) } .onReceive(clockTimer) { currentDate in s = ContentView.getSecond(currentDate) } } } #Preview { ContentView() } Any clue how to solve this issue?

I made a log analyzer which does currently use the SHELL which works fine. Now I wanted to replace it with native Swift code but the result is really slow. Here is an example with about 100 MB real log data. It needs just a second via SHELL but more than 80 seconds with Swift code. Is there a way to improve the Swift code? In SHELL I use % time (cd /regTest/logs;cat access.log access.log.1 | grep '26\/Apr' | egrep -v '(www.apple.com/go/applebot | www.bing.com/bingbot.htm | www.googlebot.com/bot.html | Xing Bot)' | awk '/GET/ {print $1}' | sort -n | uniq 1>/dev/null) 1,09s user 0,05s system 105% cpu 1,081 total Here is the result of my Swift test: % time ./regTest Found 1813 lines. 82,54s user 0,26s system 99% cpu 1:22,83 total My Swift sample code import Foundation import RegexBuilder guard let fullText = try? String(contentsOf: URL(filePath: "/regTest/logs/access.log")) + String(contentsOf: URL(filePath: "/regTest/logs/access.log.1")) else { print("Cannot read files!") exit(1) } let yesterdayRegEx = Regex { Capture { "26/Apr" } } let botListRegEx = Regex { Capture { ChoiceOf { "www.apple.com/go/applebot" "www.bing.com/bingbot.htm" "www.googlebot.com/bot.html" "Xing Bot" } } } let dateMatch = fullText.split(separator: "\n") .filter{ $0.firstMatch(of: yesterdayRegEx) != nil } .filter{ $0.firstMatch(of: botListRegEx) == nil } print("Found \(dateMatch.count) lines.")

Hi! I write a time table like app where entries on a day planner are created and modified. It works well but since the latest additions I get random crashes after clicking an UI control. Any clue how to debug such an issue?

Hi! I have a strange issue for my SwiftUI based App on macOS. Opening and saving a file works well when the app is already open. But when I double click a file in Finder to launch the App the file is not opened. When I double click the file again it gets loaded. I assume that I missed something simple but I can't get a clue from documentation and internet searching. Any clue how to proceed to open a file on application launch?

Hi! I have a strange error in my SwiftUI app and need a clue how to solve this issue. I work on a timetable like app where I hold the data in the App struct @StateObject private var appData = VorlesungsHandler() and the classes are defined as public class VorlesungsHandler : ObservableObject { let dayList : [Weekdays] = [.Montag, .Dienstag] @Published var vorlesungen : [Vorlesung] = [ Vorlesung(…), … ] … } and class Vorlesung : Hashable, Equatable, Identifiable, ObservableObject { @Published var subject: ModuleType @Published var person : Personen let vID = UUID() … } The appData object is passed down to the views and subviews via .environmentObject(appData) and it seems to work well. Now I face an error when I change the array „vorlesungen“ in Appdata via func updateVorlesung(oldID : UUID?, newV : Vorlesung) { if oldID == nil { self.vorlesungen.append(newV) return } for i in 0..<self.vorlesungen.count { if self.vorlesungen[i].vID == oldID! { self.vorlesungen.remove(at: i) self.vorlesungen.append(newV) break } } } The error message is Fatal error: Duplicate keys of type 'Vorlesung' were found in a Dictionary. This usually means either that the type violates Hashable's requirements, or that members of such a dictionary were mutated after insertion. This error does not occur every time but 30 to 50% of the changes. In my tests I did also add self.objectWillChange.send() in front of all array-change commands but it does not help. Any clue how to solve this issue?

Using a simple script to get the EXIF-information from a photo tell application "Image Events" set theOpenFile to open "/PATH/TO/IMAGE.HEIC" set theTags to name of metadata tags of theOpenFile close theOpenFile return theTags end tell I get for the same image (from an iPhone) following results macOS 13.2 {"format", "hasAlpha", "formatOptions", "typeIdentifier", "dpiHeight", "dpiWidth", "path"} macOS 10.14.6 (Mojave) {"samplesPerPixel", "hasAlpha", "dpiHeight", "dpiWidth", "bitsPerSample", "profile", "formatOptions", "ExifColorSpace", "pixelHeight", "path", "creation", "software", "space", "pixelWidth", "format", "make", "model", "typeIdentifier"} So it is no longer possible to read the image meta data using AppleScript on macOS Ventura, i.e. the creation date.

I made a test with a new XIB-based project using this code     func applicationDidFinishLaunching(_ aNotification: Notification) {         guard let content = window.contentView else {             print("Error: cannot access windows contentview!")             return         }                  let tv = NSTextView(frame: NSMakeRect(100, 300, 200, 40))         tv.string = "Text subview"         tv.font = NSFont.systemFont(ofSize: 30.0)         content.addSubview(tv)         let chartView = NSHostingView(rootView: myChart())         chartView.setFrameSize(content.frame.size)         content.addSubview(chartView)         content.printView(self)             } "myChart" is s sample view using Charts. The window does show the text and the chart but the print shows the text only. How can I get the SwiftUI-View printed? My goal is a PDF output of a SwiftUI view. There are already several older threads with similar questions but no solution, yet.

I wrote a little test app which must also run on some older Macs still using macOS 10.14.6. When I copy the app to the old Mac I get following error message: You can’t use this version of the application “APPNAME” with this version of macOS. You have macOS 10.14.6. The application requires macOS 10.14 or later. It seems to be a build bug… I use Xcode 13.3 on macOS 12.3.1. Any clue how to solve this issue?

Hi! I have an issue calling mount_smbfs with a user from a specific domain. A sample shell call is mount_smbfs -N -o nodev,nosuid "//DOMAIN;USER:PASS@SERVER_ADDRESS" /SOMEPATH Using the code below I get an invalid command because the semicolon ends the command in shell. var server = "//DOMAIN;USER:PASS@SERVER_ADDRESS" let remotePath = "/REMOTEPATH" let localPath = "/LOCALPATH" let cmd = Process() cmd.executableURL = URL(fileURLWithPath: "/sbin/mount_smbfs") cmd.arguments = ["-N", "-o nodev,nosuid", "\(server)\(remotePath)", localPath] Using a quoted semicolon var server = "//DOMAIN\;USER:PASS@SERVER_ADDRESS" does also not work, because the backslash is quoted to DOMAIN\\;USER automatically via Process class. So I end up with two backslash. Using quotes did also not work for me. Any clue how to solve this issue?

Hi! I wrote a backup console application. It does use ssh/sshfs to access a web server via public key. Also it does send an SMTP-mail when finished. If the process is started via launchctl load DAEMON it works always properly (RunAtLoad is true). But when the daemon is called automatically at night it does not always work. In my log I get these errors: ssh: connect to host SERVERURL port 22: Undefined error: 0 and Failed sending: NIOConnectionError(host: "mail.mydomain", port: 25, dnsAError: Optional(NIOCore.SocketAddressError.unknown(host: "mail.mydomain", port: 25)), dnsAAAAError: Optional(NIOCore.SocketAddressError.unknown(host: "mail.mydomain", port: 25)), connectionErrors: []) it does run on a MacMini M1 with macOS 12.2. Any clue what's wrong or how to find the reason of this issue? PS. On another MacMini (Intel) with macOS 11.6 the backup works since a year but there is always an admin user logged in.

Hi! I need a clue how to solve this issue. I can't build a universal command line app on my new MacBook Pro. I use Swift with some Swift packages and get the error Could not find module 'NIO' for target 'x86_64-apple-macos'; found: arm64, arm64-apple-macos, at: BUILDPATH Where do I have to look in Xcode (v 13.1) to get universal packages?

Hi! I wrote a backup program in Swift which is used for several servers. It does send an email each day about the backup status. Currently I use /usr/bin/mail because it works well with via postfix configuration. Now I need to add an attachment (an image about the access statistics) and this is not possible using the mail command. I looked at the docs and I found NSSharingService(named: NSSharingService.Name.composeEmail) but it does just create a mail which is opened in Mail.app. Is there really no OS provided way to send an SMTP mail without any user interaction? I don't want to implement a 3rd party SMTP-Library. TIA, GreatOm
